RESUMO

ISSUE: Postpartum depressive symptoms may be more prevalent and/or severe in vulnerable populations. BACKGROUND: Postpartum depression represents a serious mental health problem associated with maternal suffering. Despite the relevance and clinical implications of investigating pain during pregnancy and the association with postpartum depression, there is limited research on this topic. AIM: We evaluated the association between pain during pregnancy and postpartum depression symptoms in adolescent and adult women. METHODS: This study included 86 pregnant women (42 adolescents aged 13 to 18 years and 44 adults aged 23 to 28 years) from Trairi region, Northeastern Brazil. The evaluation of pain intensity and postpartum depression symptoms was conducted using the validated instruments of the Pelvic Pain Assessment Form and Edinburgh Postnatal Depression Scale (EPDS), respectively. Mann-Whitney and Kruskal-Wallis tests compared depressive symptoms in relation to pain status. FINDINGS: Overall, pregnant women reporting moderate to intense pain presented more depressive symptoms, with emphasis to "deep pain with intercourse" (p = .09), "burning vaginal pain after sex" (p = .01), "pelvic pain lasting hours or days after intercourse" (p = .06), and "pain with urination" (p = .09). When stratified by age group, significant associations were found only for the adolescents. DISCUSSION: Our results suggest that women reporting pain in different daily situations have higher EPDS scores. CONCLUSION: Pain during pregnancy is associated with postpartum depression symptoms, mainly among adolescents. Adequate screening and pain management during pregnancy may improve women's quality of life.

RESUMO

BACKGROUND: Symptomatic irreversible pulpitis often results in heightened reactions to thermal stimuli such as pain evoked by a cold stimulus, and spontaneous odontogenic pain (unprovoked pain). OBJECTIVE: This study primarily compared the clinical manifestations of odontogenic spontaneous pain and pain provoked by cold stimulus specifically focusing on their sensory discriminative characteristics (intensity, duration and quality) between symptomatic irreversible pulpitis patients with and without referred pain. METHODS: Twenty-three patients with symptomatic irreversible pulpitis with referred pain and 12 patients without referred pain were included in this cross-sectional study. The following outcomes were assessed: odontogenic spontaneous pain and its descriptors; pain evoked by cold stimulus and qualitative sensory testing before and after local anaesthesia; referred pain location; use of analgesic medication; complementary anaesthesia efficacy. T-test, chi-squared and McNemar tests were applied to the data (p < .50). RESULTS: Patients with referred pain presented a greater odontogenic pain intensity (p < .05) when considered the average of the last 24 h. These patients also showed higher pain rating and pain descriptors (p < .05). Intensity and duration of the pain evoked by cold stimulus in the non-affected contralateral tooth at baseline were higher for patients with referred pain (p < .05). CONCLUSION: Symptomatic irreversible pulpitis patients with referred pain present greater odontogenic spontaneous pain and a heightened pain sensitivity. Therefore, patients with referred pain seem more complex from a pain severity perspective, supporting the clinical utility of discriminating symptomatic irreversible pulpitis with and without referred pain.

RESUMO

BACKGROUND: Local anesthetic puncture is often related to the experience of pain. This study aimed to systematically analyze the literature on changes in pain perception during the anesthetic puncture of dental local anesthesia after Photobiomodulation Therapy (PBMT). MATERIAL AND METHODS: An electronic search was performed in eight primary databases (Embase, LILACS, BBO, LIVIVO, MedLine via PubMed, SciELO, Scopus, and Web of Science) and three additional ones (EASY, Google Scholar, and OATD) to partially capture the "gray literature". The PICO strategy was used to identify randomized clinical trials evaluating the analgesic effect of PBMT in the anesthetic puncture site of dental local anesthesia compared to placebo or control groups, without restrictions on publication language and year. Two reviewers extracted the data and assessed the individual risk of bias of the eligible studies using the Cochrane Collaboration Risk of Bias Tool version 2.0. RESULTS: The electronic search found 3,485 records, of which eight met the eligibility criteria and were included in the qualitative synthesis. The studies were published from 2011 to 2022. None of the included studies had a low risk of bias. PBMT groups showed no significant difference in pain scores compared to placebo and control groups of most studies. CONCLUSION: Based on a low to very low certainty of evidence, PBMT seems to have no effect on pain perception during anesthetic puncture in patients undergoing dental local anesthesia.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to a change of pedagogical strategies from on-campus to "online" modality (synchronous and asynchronous learning) and may influence the health of university students, including their mental workload. OBJECTIVE: To identify the association between mental workload, perception of musculoskeletal discomfort (MSD), and the level of physical activity of Masters's students' online learning due to the pandemic. METHOD: This was a pilot descriptive study with a cross-sectional, quantitative, non-experimental study design. The sample consisted of 20 students. To collect the data, the participants answered a sociodemographic questionnaire, NASA-Task Load Index, International Physical Activity Questionnaire, and the Nordic Musculoskeletal Questionnaire. RESULTS: The students presented mental workload at medium (45%) and high (55%) levels, with time demands as the most prevalent dimension. In addition, 80% of the students reported experiencing MSD in the last seven days, with the most frequent areas being the neck and lower back. Regarding the level of physical activity, five students had a low level (25%), five students had a medium level (25%), and ten students had a high level (50%) of activity. CONCLUSION: Most of the students (95%) conduct their master's degree along with maintaining a full-time job. Therefore, the adaptive requirements according to "time demands" is a negative factor because of its contribution to mental workload. Especially in addition to students' perception of musculoskeletal discomfort, organizational aspects would be fundamental to prevent physical and mental health risks.

RESUMO

Abstract Aim: Polymorphisms in the COMT gene can alter enzymatic functions, raising levels of endogenous catecholamines, which stimulates beta-adrenergic receptors related to pain. This study aimed to evaluate whether a polymorphism in the COMT gene (rs4818) is associated with dental pain in children. Methodology: A cross-sectional study was conducted with a representative sample of 731 pairs of children and parents randomly selected from a population-based sample of eight-year-old children. Reports of dental pain was evaluated using a question directed at the parents and self-reported pain using the Faces Pain Scale - Revised. Dental caries experience was determined using the Decayed, Missing, and Filled Teeth (DMFT) index. For genetic analysis, DNA was obtained from oral mucosa epithelial cells of 352 children randomly selected from the initial sample. Results: Children with the CC genotype had higher odds of reporting moderate to intense pain than those with the GG genotype (OR=3.60; 95% CI=0.80-16.20; p=0.03). These same children had greater odds of parental reports of pain (OR=1.93; 95% CI=0.91-4.08; p=0.02). Moreover, lower schooling of parents/guardians and caries experience in the primary dentition were significantly associated with greater odds of a parental report of dental pain (OR=2.06; 95% CI=1.47-2.91; p<0.001; OR=6.26; 95% CI=4.46-8.78; p<0.001). Conclusions: The rs4818 polymorphism of the COMT gene is associated with dental pain. Children with the C allele are more likely to report higher levels of pain. Clinical Relevance: Even though the experience of pain is subjective and multifactorial, this study raises the hypothesis that there is a genetic predisposition to dental pain that should be considered in clinical practice.

RESUMO

Objetivo:Revisar sistematicamente a literatura sobre a efetividade do método computadorizado de anestesia odontológica em relação àdor, comportamento não colaborador e o medo/ansiedade em crianças e adolescentes em comparação com o método convencional. Materiais e métodos:Uma buscaeletrônica foi realizada em cinco base de dados (Biblioteca Virtual em Saúde, Scopus, Embase, Pubmed e Web of Science)e que incluiu ensaios clínicos randomizados. A busca foi realizada em outubro de 2020 eatualizada em maio de 2021 e, não houve restrição de data ou idioma. A avaliação de risco de viés foi realizada usando aRoB 2 e, tambémfoi realizada uma análise qualitativa. Resultados:Foram encontrados 3.518 estudos, e após a remoção das duplicatas, análise do título e resumo e,leitura completa, restaram 26 estudos incluídos. Destes,cinco avaliaram ansiedade/medo, doze avaliaram o comportamento durante a anestesia, e vinte e dois avaliaram a percepção de dor. Não foi observadodiferença significativa na maioria dos estudos entreo uso do método computadorizado em comparação ao método tradicionalpara todos os desfechos analisados. Discussão:Apesar de não parecer haver diferença significativa na percepção de dor, no relato de medo/ansiedade e no comportamento entre o uso do método computadorizado emcomparação ao método tradicional, é fundamentalavaliar o comportamento da criança durante o atendimento odontológico pois suas expressões podem indicar algum desconforto e dor. Esses achados devem ser interpretados com cautela, considerando que quase três quartos dos estudos incluídos apresentaram alto risco de viés. Conclusão:Mesmo com a ausência de diferença, os dispositivos eletrônicos são promissores, visto que promovem uma administração lenta e controlada e resultam em uma anestesia segura e eficaz que coloca-se como alternativa a prática clínica.

Aim:To systematically review the literature on the effectiveness of the computerized method of dental anesthesia in relation to pain, non-collaborative behavior and fear/anxiety in children and adolescents compared to the conventional method. Materials and methods:An electronic search was performed in five databases (Virtual Health Library, Scopus, Embase, Pubmed and Web of Science)that included randomized clinicaltrials. The search was performed in October 2020 and updated in May 2021. The risk of bias assessment was performed using the RoB 2 andaqualitative analysis was also performed. Results:A total of 3,518 studieswere found, and after removing duplicates, analyzing the title and abstract, and completereading, 26 studies remainedincluded. Of these, five assessed anxiety/fear, twelve assessed behavior during anesthesia, and twenty-two assessed pain perception. No significant difference was observed in most studies between the use of the computerized method compared to the traditional method for all outcomesanalyzed. Discussion:Although there does not seem tobe a significant difference in pain perception, fear/anxiety reports and behavior between the use of the computerized method and the traditional method, it is fundamental to evaluate the child's behavior during dental care, as their expressions may indicate some discomfort and pain. These findings should be interpreted with caution, considering that nearly three-quarters of the included studies were at high risk of bias. Conclusion:Even with the absence of difference, electronic devices are promising, as they promote slow and controlled administration and result in safe and effective anesthesia, which is an alternative to clinical practice.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: Although craniofacial pain has been associated with negative psychological aspects, how the patient's perception of their own illness could influence craniofacial pain is not elucidated yet. Therefore, this study aims to identify the main factors and beliefs about the illness that could influence pain intensity and pain duration in people who experienced craniofacial pain in the last 24 hours. METHODS: This cross-sectional study comprised undergraduate students, aged between 18 and 40 years old, who experienced self-reported craniofacial pain in the last 24 hours. Participants answered questions regarding body functions, activities and participation, and personal factors based on the International Classification of Functioning (ICF); In addition, questions from the Brief Illness Perceptual Questionnaire (Brief IPQ) were applied. The analysis was carried out with a single and multiple regression model. RESULTS: The sample comprised 87 volunteers. Pain intensity and duration experienced in the last 24 hours were associate by concerns about the presence of an illness and the need for treatment. Pain intensity was specifically associated with the importance of treatment and the extent to which the patient is concerned about their pain (R2=0.108). Pain duration was associated with how much the individual is worried about their illness (R2=0.1459). CONCLUSION: Both pain intensity and duration experienced in the last 24 hours are associated with concerns regarding the presence of an illness and beliefs related to such illness treatment, which reinforces the influence of psychosocial aspects on pain perception.

RESUMO JUSTIFICATIVA E OBJETIVOS: Embora a dor craniofacial seja associada a aspectos psicológicos negativos, ainda não está totalmente elucidado como a percepção do paciente sobre sua própria doença pode influenciá-la. Portanto, este estudo teve como objetivo identificar os principais fatores e as crenças sobre a doença que podem influenciar a intensidade e a duração da dor em pessoas que sentiram dor craniofacial nas últimas 24 horas. MÉTODOS: Estudo transversal composto por universitários, com idade entre 18 e 40 anos, que relataram dor craniofacial nas últimas 24 horas. Os voluntários responderam a perguntas sobre funções corporais, atividades e participação e fatores pessoais com base na classificação da Classificação Internacional de Funcionalidades (CIF). Além disso, foram aplicadas questões do Questionário de Percepção de Doenças Versão Breve (Brief IPQ). A análise foi realizada com um modelo de regressão simples e múltiplo. RESULTADOS: A amostra foi composta por 87 voluntários. A intensidade e a duração da dor sentida nas últimas 24 horas foram influenciadas pela preocupação com a presença de doença e com a necessidade de tratamento. A intensidade da dor foi associada à importância do tratamento e à preocupação do paciente com sua dor (R2=0,108). A duração da dor associou-se à preocupação do indivíduo com sua doença (R2=0,1459). CONCLUSÃO: Tanto a intensidade quanto a duração da dor vivenciadas nas últimas 24 horas são influenciadas pela preocupação com a presença de doença e crenças relacionadas ao seu tratamento, o que reforça a influência dos aspectos psicossociais na percepção da dor.

RESUMO

Background: Surgical and non-surgical periodontal procedures often lead to postoperative pain. Clinicians use pharmacological methods such as anesthetics, anti-inflammatory drugs, and analgesics for relief. However, the multitude of options makes it challenging to select the best approach for routine dental care. Objective: This review aimed to describe previous studies regarding the pharmacological management used for pain control during periodontal procedures as well as factors that may interfere with patients' perception of pain. Methods: We included studies (period of 2000-2023, whose approach corresponded to the pharmacological protocols used for preoperative, trans-operative, and postoperative pain control in adult patients undergoing surgical and non-surgical periodontal therapy. Results: A total of 32 studies were included in the analysis, of which 17 (53%) were related to anesthetic methods and 15 (47%) were related to therapeutic protocols (anti-inflammatory/analgesic agents). These studies predominantly involved nonsurgical periodontal procedures. Studies have reported that factors related to age, type of procedure, and anxiety can influence pain perception; however, only seven of these studies evaluated anxiety. Conclusions: Numerous methods for pain control can be applied in periodontal therapy, which are accomplished through anesthetic methods and/or therapeutic protocols. Factors such as anxiety, age, and type of procedure are related to pain perception in patients. Thus, it is the responsibility of dentists to evaluate each clinical situation and define the best protocol to follow based on the literature.

RESUMO

OBJECTIVES: The aim of this systematic review was to compare the expectation and perception of pain reported by patients before and after the installation of interradicular mini-implants. MATERIALS AND METHODS: Electronic search was performed in six databases. Inclusion criteria were randomized controlled trials (RCTs) or non-randomized controlled clinical trials (nRCTs); studies using mini-implants in the interradicular region; assessment of pain intensity by visual analogue or numerical scale. The risk of bias assessment was based on the Rob 2 tool and Robins-I. RESULTS: A total of 1566 articles were retrieved, and 21 met the eligibility criteria. Six were classified as high risk, one as critical and the other one as uncertain, according to the Robins-I tool. In articles evaluated by the Rob2 tool, ten were classified as serious risk and three as moderate risk. A meta-analysis was also performed. Weighted means were calculated among the studies using the random-effects model and forest plots were generated. Heterogeneity was assessed through the Q test and I2 statistics. It was observed, with moderate evidence, that on a scale of 0 to 10, the pain expectation (effect size 4.75) is higher than that effectively pain generated by the procedure (effect size 1.94). CONCLUSION: Pain expectation was greater than that actually generated by the procedure, being almost non-existent 7 days postoperatively. CLINICAL RELEVANCE: This study may help the clinician to reassure the patient regarding the sensations that could be experienced during and after the installation.

RESUMO

In this study, we sought to determine the prevalence of musculoskeletal injuries, perceived pain, and physical activity level among Brazilian practitioners of strength training (ST) and functional fitness (FF). Participants were 311 men and women who trained in 10 FF training centers and seven ST gyms. Each participant completed surveys of the prevalence of musculoskeletal injuries, their pain perception, and their physical activity level. A chi square test was used to analyze associations between groups and distributions of injuries. When any significant difference was observed, the difference score was analyzed through the adjusted residual values. Fisher's exact test was used to determined the associations between musculoskeletal injury prevalence and training modality (FF and ST) and between musculoskeletal injury prevalence and practice frequency (times/wk). To measure the magnitude of association between variables, the Phi coefficient was calculated for 2x2 associations and Cramer's V was used whenever the distributions were outside this standard. When the dependent variable presented a dichotomous characteristic, an Odds Ratio (OR) was calculated with a confidence interval of 95%. We found a higher musculoskeletal injury prevalence in the axial skeleton (n = 52; 83.88%) in FF practitioners and in the lower limbs of ST practitioners (n = 9; 52.96%). When the physical activity level cutoff point was set at 300 minutes per week, there was a significant relationship between physical activity and training modality (p = 0.005). There was also a significant association between pain perception and musculoskeletal injury (p < 0.001). Clinical follow-up was a protective factor to being injured (OR = 0.18; CI = 0.06-0.49), and, even after multivariate analysis this significant association was maintained (OR = 0.03; CI = 0.01 - 0.08). Thus, FF practitioners reported more musculoskeletal injuries than STs, and follow-up medical or physical therapy was a protective factor to these injuries. FF practitioners also had a higher level of weekly physical activity weekly than ST practitioners. Functional fitness practitioners may be at a higher risk of injuries than those who participate in traditional strength training.

RESUMO

INTRODUCTION: Oxytocin (OXT) is a peptide hormone produced in the hypothalamus that plays a neuromodulatory role in emotion, stress, and anxiety. Due to its multidimensional role, OXT is a promising target for therapeutic interventions to treat pain. OBJECTIVE: Perform a systematic literature review, followed by a meta-analysis to identify the effects of intranasal OXT on the self-perception of clinical and experimental pain among human subjects. METHOD: A systematic review was conducted in the PubMed, PsycINFO, Scielo, Lilacs, and Web of Science databases, using the keywords Oxytocin, Pain, Analgesia, and Nociception. RESULTS: Fifteen papers were included in the meta-analysis. None of the outcomes presented statistical significance in terms of the interventions' effect size: pain intensity (SMD = -0.02 (CI 95 %: -0.14 to 0.10; p = 0.76)) and pain unpleasantness (SMD = -0.15 (CI 95 %: -0.34 to 0.04; p = 0.12)). No meta-analysis was performed for pain threshold or tolerance because few papers address these outcomes. CONCLUSION: There was no statistically significant effect of intranasal OXT administration on pain perception, considering equivalence limits between (-0.2 and 0.2). However, it must be considered that the study designs may not have been sensitive enough to detect minor analgesic effects of OXT, which, being weak, may also not be perceived at a conscious level. Additionally, OXT effects possibly depend on specific characteristics of the painful condition, such as pain complexity, intensity, and duration, contextual variables like the presence of social and affective support, and individual characteristics.

RESUMO

Background: Resting-state functional connectivity (rs-FC) may aid in understanding the link between pain-modulating brain regions and the descending pain modulatory system (DPMS) in fibromyalgia (FM). This study investigated whether the differences in rs-FC of the primary somatosensory cortex in responders and non-responders to the conditioned pain modulation test (CPM-test) are related to pain, sleep quality, central sensitization, and the impact of FM on quality of life. Methods: This cross-sectional study included 33 females with FM. rs-FC was assessed by functional magnetic resonance imaging. Change in the numerical pain scale during the CPM-test assessed the DPMS function. Subjects were classified either as non-responders (i.e., DPMS dysfunction, n = 13) or responders (n = 20) to CPM-test. A generalized linear model (GLM) and a receiver operating characteristic (ROC) curve analysis were performed to check the accuracy of the rs-FC to differentiate each group. Results: Non-responders showed a decreased rs-FC between the left somatosensory cortex (S1) and the periaqueductal gray (PAG) (P < 0.001). The GLM analysis revealed that the S1-PAG rs-FC in the left-brain hemisphere was positively correlated with a central sensitization symptom and negatively correlated with sleep quality and pain scores. ROC curve analysis showed that left S1-PAG rs-FC offers a sensitivity and specificity of 85% or higher (area under the curve, 0.78, 95% confidence interval, 0.63-0.94) to discriminate who does/does not respond to the CPM-test. Conclusions: These results support using the rs-FC patterns in the left S1-PAG as a marker for predicting CPM-test response, which may aid in treatment individualization in FM patients.

RESUMO

ABSTRACT Objective: We hypothesized that perinatal manipulations of the nitrergic system would affect adult animal behaviors. Methods: We tested this hypothesis by perinatally administering N(G)-Nitro-L-arginine methyl ester (L-NAME), a non-specific antagonist of nitric oxide synthase for 15 days and assessed anxiety- and depression-like behaviors in adult mice. At 70 days of age, the mice were subjected to a battery of tests consisting of the open-field, light/dark box, forced swim, and tail-flick tests. The tests were performed at two-day intervals, and the order of the tests within the battery was determined according to the progressive invasiveness degree. Results: L-NAME-treated animals exhibited decreased anxiety-like behavior in the light/dark box and open field tests, with no change in locomotor activity. Additionally, they demonstrated decreased depression-like behavior in the forced swim test and no change in pain perception in the tail-flick test. Conclusion: The nitrergic system is possibly involved in neural circuitry development that regulates behaviors since blocking perinatal nitric oxide production decreases anxiety- and depression-like behaviors in adult mice.

RESUMO

Pain is present in the dental clinic, whether due to oral problems such as dental caries and its complications or related to dental procedures. Pain evaluation in patients with communication difficulties (PCDs) is challenging for dentists, potentially compromising treatment. The aim of this study was to develop and validate an instrument to assess the perception of dentists about pain in PCDs. This study followed a quantitative methodological approach involving constructing and validating an instrument administered to 50 dentists. The initial instrument consisted of 29 items divided into four domains. Content and construct validity and internal consistency were confirmed. Content validation was performed by judges using the Content Validity Index. The instrument underwent construct validation and internal consistency assessments through exploratory factor analysis and confirmatory factor analysis using Cronbach's α, Kaiser-Meyer-Olkin, and Bartlett's sphericity tests. The final instrument consisted of 21 items divided into three domains, with a high Cronbach's α for one domain and moderate values for the others. The total variance accounted for was above 46.03%. Each factor retained at least three items, with factor loadings greater than 0.3, commonalities greater than 0.2, and eigenvalues >1. Despite the study's limitations, the instrument demonstrated its applicability and potential in evaluating the perception and management of pain in PCDs.

RESUMO

Resumo Mediante estudo observacional, transversal e quantitativo que utilizou os instrumentos de avaliação Brief Pain Inventory (dor), Functional Assessment of Chronic Illness Therapy Spiritual Well-Being (bem-estar espiritual) e Beck Depression Inventory - Short Form (depressão), busca-se avaliar a influência da espiritualidade e da depressão na percepção de dor de pacientes acometidas por neoplasia de mama metastática. A idade média foi 57,3 anos e, das 30 participantes, 24 (80%) tratavam-se em serviço público; 17 (57%) tinham diagnóstico de câncer de mama há mais de cinco anos; e 27 (90%) realizavam alguma prática religiosa/espiritual. Pacientes com escore de bem-estar espiritual acima da mediana apresentaram menor escore dos sintomas depressivos (3 vs . 6; p =0,021). Não houve diferença significativa em relação à mediana do escore total do bem-estar espiritual quando estratificado pela mediana da percepção de dor (31,5% vs . 28,5%; p =0,405). Maior manifestação de bem-estar espiritual pode estar relacionada a menores índices de depressão.

Abstract This observational, cross-sectional and quantitative study, by means of the assessment instruments Brief Pain Inventory, Functional Assessment of Chronic Illness Therapy Spiritual Well-Being and Beck Depression Inventory - Short Form, evaluated the influence of spirituality and depression in the pain perception of patients with metastatic breast cancer. Mean age was 57.3 years. Of the 30 participants, 24 (80%) were treated in a public service, 17 (57%) had been diagnosed with breast cancer for more than 5 years, and 27 (90%) were religious or spiritual. Patients with spiritual well-being scores above the median had lower depressive symptom scores (3 vs. 6; p =0.021). The median total score of spiritual well-being showed no significant difference when stratified by median pain perception (31.5% vs. 28.5%; p =0.405). Greater spiritual well-being may be related to lower rates of depression.

Resumen Este estudio observacional, transversal y cuantitativo utilizó los instrumentos Brief Pain Inventory (dolor), Functional Assessment of Chronic Illness Therapy Spiritual Well-Being (bienestar espiritual) y Beck Depression Inventory - Short Form (depresión), para evaluar si la espiritualidad y la depresión influencian en la percepción del dolor en pacientes con cáncer de mama metastásico. La edad promedio fue de 57,3 años; de las 30 participantes, 24 (80%) recibían atención pública; 17 (57%) tenían diagnóstico de cáncer de mama hace más de cinco años; y 27 (90%) solían tener alguna práctica religiosa/espiritual. Aquellas con puntuación de bienestar espiritual superior a la mediana tuvieron una puntuación más baja de síntomas depresivos (3 vs. 6; p =0,021). No hubo diferencias significativas en la mediana de la puntuación total de bienestar espiritual cuando se estratificó por la percepción mediana del dolor (31,5% vs. 28,5%; p =0,405). Una mayor sensación de bienestar espiritual se relacionó a bajas tasas de depresión.

RESUMO

Background: Probing of the periodontal pocket is an essential part of the diagnosis of periodontal disease and 15-77% of untreated periodontal patients experience pain during probing. Therefore, the objective of this study is to evaluate the pain perceived by patients with dental plaque-induced gingivitis and chronic periodontitis during periodontal probing and the main objective includes the evaluation of the relationship between pain perceived during periodontal probing and gingival inflammatory parameters. Material and Methods: A total of 475 participants were recruited into the study. The patients were divided into two groups: Group-A (Gingivitis Group - 275 patients) and Group-B (Chronic Periodontitis Group - 200 patients). Clinical parameters included analysis of bleeding on probing, simplified gingival index, pocket depth on probing, and clinical attachment level. Pain score was recorded using the HP VAS scale and all patients participated in the study after a detailed explanation of the study protocol. Results: A significant difference in pain perception was noted between groups, highlighting the role of the degree of inflammation in the examination of periodontal parameters. Conclusion: Within the limitations of the present study, we can conclude that pain perception is directly correlated with the degree of inflammation in periodontitis rather than plaque-induced gingivitis during periodontal probing. Therefore, some form of adjuvant topical anesthesia may be considered in order to reduce pain levels in severely inflamed patients, to encourage continued acceptance of supportive periodontal therapy.

Antecedentes: El sondaje de la bolsa periodontal es una parte esencial en el diagnóstico de la enfermedad periodontal. 15-77% de los pacientes periodontales no tratados experimentan dolor durante el sondaje. Por lo tanto, el objetivo de este estudio es evaluar el dolor percibido por pacientes con gingivitis inducida por placa dental y periodontitis crónica durante el sondaje periodontal y el objetivo principal incluye la evaluación de la relación entre el dolor percibido durante el sondaje periodontal con parámetros inflamatorios gingivales. Material y Métodos: Un total de 475 sujetos fueron reclutados en el estudio. Los sujetos se dividieron en 2 grupos: Grupo - A (Grupo de gingivitis - 275 pacientes) y Grupo - B (Grupo de periodontitis crónica - 200 pacientes). Los parámetros clínicos incluyeron el análisis del sangrado al sondaje, el índice gingival simplificado, la profundidad de la bolsa al sondaje y el nivel de inserción clínica. La puntuación del dolor se registró utilizando la escala HP VAS y todos los pacientes participaron en el estudio después de una explicación detallada del protocolo del estudio. Resultados: Se notó una diferencia significativa en la percepción del dolor en el grupo B que en el grupo A, lo que significa el papel del grado de inflamación en el examen de los parámetros periodontales. Conclusión: Dentro de las limitaciones del presente estudio, podemos concluir que la percepción del dolor se correlaciona directamente con el grado de inflamación que se observa en la periodontitis más que con la gingivitis inducida por la placa dental durante el sondaje periodontal. Por lo tanto, se puede considerar alguna forma de anestesia tópica adyuvante para reducir los niveles de dolor en pacientes gravemente inflamados para fomentar la aceptación continua de la terapia periodontal de apoyo.

RESUMO

BACKGROUND: Hemiplegic shoulder pain (HSP) is common after stroke. The pain perception may exacerbate changes in the motor behavior of the ipsi-lesional upper limb, contributing to the functional decline of an individual's motor performance. OBJECTIVE: This study evaluates the influence of pain perception on the aiming movements performed with the ipsilesional upper limb in individuals with unilateral chronic stroke. METHODS: A cross-sectional study was conducted with 41 participants divided into three groups: 1) stroke with contralesional shoulder pain ≥ 3 by the Visual Numerical Pain Scale (SPSG; n = 13); 2) stroke no shoulder pain (nSPSG; n = 14); and 3) healthy control (CTG; n = 14) matched by sex and age. Individuals with stroke were matched for the severity of sensorimotor impairment by the Fugl-Meyer upper limb subscale and the injured hemisphere side. Stroke groups performed aiming movements with the ipsilesional upper limb and the CTG with the corresponding limb using a pen tip on the sensitive surface of a digitizing tablet. Performance across groups was compared by one-way analysis of variance, considering the time since injury as a covariate. The planning and execution variables of the movement trajectory were analyzed, and the significance was set at 5%. RESULTS: Trajectories of the SPSG were slower (p = .010; η2 = 0.22), were less smooth (p = .002; η2 = 0.30), had more directional error (p = .002; η2 = 0.28), and were less accurate (p = .034; η2 = 0.17) than the CTG. The nSPSG and CTG showed similar performance. CONCLUSIONS: The perception of pain impairs aiming movements performed with the ipsilesional upper limb in individuals with unilateral chronic stroke.

RESUMO

Background: Probing of periodontal pockets is an essential part in the diagnosis of periodontal disease. Fifteen to seventy seven percent of untreated periodontal patients experience pain during probing. Hence the aim of this study is to evaluate the pain perceived by patients with gingivitis and periodontitis during periodontal probing. The goals of this study were to compare the patients' pain perception when using a conventional UNC15 probe and a manual pressure sensitive periodontal probe, and to relate the clinical features of gingivitis and periodontitis to the discomfort associated with periodontal probing. Material and Methods: A total of 475 subjects were recruited into the study. The subjects were initially divided into two groups ­ Group ­ A (Gingivitis group - 275 patients) and Group ­ B (Chronic Periodontitis group -200 patients) according to the AAP 1999 Classification. These two groups were further subdivided into two groups each (Gingivitis ­ Conventional Probe ­ GCP, Gingivitis ­ Manual Pressure Sensitive Probe ­ GMPS, Periodontitis - Conventional Probe ­ PCP, Periodontitis ­ Manual Pressure Sensitive Probe ­ PMPS) using a computer generated program of random numbers. Results: A significant difference was noted in pain perception when pressure sensitive probe was used compared to conventional UNC-15 probe. Reduced Bleeding on Probing and Pain scores were noted in Chronic periodontitis subjects with use of pressure sensitive probe, which was statistically significant (p<0.001). Conclusion: Dentistry has changed its focus towards painless dentistry. In this context, the present study presents data towards use of manual pressure sensitive probes, which offers an advantage of low cost when compared to more advanced computerized systems with reduced pain during periodontal examination. It could result in a positive attitude of the patients towards continuous supportive periodontal therapy thereby monitoring periodontal health.

Antecedentes: El sondaje de los sacos periodontales es una parte esencial en el diagnóstico de la enfermedad periodontal. Del quince al setenta y siete por ciento de los pacientes periodontales no tratados experimentan dolor durante el sondaje. De ahí que el objetivo de este estudio fué evaluar el dolor percibido por pacientes con gingivitis y periodontitis durante el sondaje periodontal. Los objetivos de este estudio fueron comparar la percepción del dolor de los pacientes al usar una sonda UNC15 convencional y una sonda periodontal sensible a la presión manual, y relacionar las características clínicas de la gingivitis y la periodontitis con la incomodidad asociada con el sondaje periodontal. Material y Métodos: Un total de 475 sujetos fueron reclutados en el estudio. Los sujetos se dividieron inicialmente en dos grupos - Grupo - A (grupo de Gingivitis - 275 pacientes) y Grupo - B (grupo de Periodontitis Crónica - 200 pacientes) de acuerdo con la Clasificación AAP 1999. Estos dos grupos se subdividieron en dos grupos cada uno (Gingivitis - Sonda convencional - GCP, Gingivitis - Sonda manual sensible a la presión - GMPS, Periodontitis - Sonda convencional - PCP, Periodontitis - Sonda manual sensible a la presión - PMPS) usando un programa generado por computadora de datos aleatorios. números. Resultados: Se notó una diferencia significativa en la percepción del dolor cuando se usó una sonda sensible a la presión en comparación con la sonda UNC-15 convencional (p<0,001). Conclusion: La odontología ha cambiado su enfoque hacia una odontología sin dolor. En este contexto, el presente estudio presenta datos hacia el uso de sondas manuales sensibles a la presión, que ofrece una ventaja de bajo costo en comparación con sistemas computarizados más avanzados con reducción del dolor durante el examen periodontal. Podría resultar en una actitud positiva de los pacientes hacia la terapia periodontal de apoyo continuo, monitoreando así la salud periodontal.

RESUMO

Abstract Objective: To analyze the regions that trigger the attention of adults' gaze when assessing pain in newborn infants' pictures and to verify if there are differences between health and non-health professionals. Method: Experimental study with 84 health professionals and 59 non-health professionals, who evaluated two images of 10 neonates, one at rest and the other during a painful procedure. Each image was shown for 7 seconds on a computer screen, while eye movements were tracked by the Tobii TX300 EyeTracker. After evaluating each image, participants gave a score from 0 (absent pain) to 10 (maximum pain), according to their perception of neonatal pain. For each image, the number and total time of gaze fixations in the forehead, eyes, nasolabial furrow, and mouth were studied. Comparisons between both groups of adults were made by an intraclass correlation coefficient, Student's t-test, and Bland Altman graphic. Results: Health professionals (93% female; 34 ± 9 years old), compared to non-health professionals (64% female; 35 ± 11 years old), gave lower scores for images at rest (0.81 ± 0.50 vs. 1.59 ± 0.76; p = 0.010), with no difference for those obtained during the painful procedure (6.98 ± 1.08 vs. 6.73 ± 0.82). There was a strong or almost perfect correlation for the number of fixations in the mouth, eyes, forehead, and for the total fixation time in the eyes and forehead. Conclusions: Adults, irrespective of their profession, showed a homogeneous gaze pattern when evaluating pictures of neonates at rest or during a painful procedures.
