RESUMEN

INTRODUCTION: Conservative treatments such as physical therapies are usually the most indicated for the management of musculoskeletal pain; therefore, a detailed description of interventions enables the reproducibility of interventions in clinical practice and future research. The objective of this study is to evaluate the description of physical interventions for musculoskeletal pain in children and adolescents. METHODS: We considered randomized controlled trials that included children and adolescents between 4 and 19 years old with acute or chronic/persistent musculoskeletal pain. We included physical therapies related to all types of physical modalities aimed at reducing the intensity of pain or disability in children and adolescents with musculoskeletal pain. The description of interventions was assessed using the Template for Intervention Description and Replication (TIDieR) checklist. We performed electronic searches in the following databases: CENTRAL, MEDLINE, EMBASE, CINAHL, PsyINFO and PEDro up to April 2024. The description of physical interventions was presented using frequencies, percentages and 95% confidence intervals (CIs) of the TIDieR checklist items described in each study. We also calculated the total TIDieR score for each study and presented these data as mean and standard deviation. RESULTS: We included 17 randomized controlled trials. The description measured through the TIDieR checklist scored an average of 11 (5.2) points out of 24. The item of the TIDieR that was most described was item 1 (brief name) and most absent was item 10 (modifications). CONCLUSION: The descriptions of physical interventions for the treatment of musculoskeletal pain in children and adolescents are partially described, indicating the need for strategies to improve the quality of description to enable true clinical reproducibility.

RESUMEN

BACKGROUND: Estimates of prevalence of musculoskeletal pain in children and adolescents vary considerably and the impact of pain on children's life is often not considered. OBJECTIVE: To determine the one-month prevalence of disabling musculoskeletal pain in children and adolescents. The secondary aims are to: 1) determine the body region with the highest prevalence; 2) understand the characteristics of the children with disabling musculoskeletal pain; and 3) describe the parents' perception of the prevalence. METHODS: This cross-sectional study was conducted in public and private schools in the states of São Paulo and Ceará, Brazil. Children self-reported presence and impact of pain, pain intensity, psychosomatic symptoms, and quality of life. Parents completed parent-proxy versions and perception of the child's sleep quality. Descriptive statistics were used to summarise the data. RESULTS: A total of 2,688 children and adolescents were included in this study. The prevalence of disabling musculoskeletal pain in the previous month was 27.1%. The back was the region most often affected (51.8%). Children with disabling musculoskeletal pain were older, heavier, had worse relationships with their family, perceived their backpacks as heavy, carried their backpacks more with one shoulder, had more negative psychosomatic symptoms, had poorer quality of life, and had higher pain intensity. Parents tended to underestimate the presence of pain in their children. CONCLUSION: The one-month prevalence of activity limiting musculoskeletal pain in children and adolescents was 27.1% with the back being the most often affected body region. Parents tended to underestimate the presence of pain in their children.

RESUMEN

BACKGROUND: The social restrictions resulting from the COVID-19 pandemic had a great impact on the routine of children and adolescents, with important consequences such as sleep, eating, and psychological/psychiatric disorders. Even though there are no studies on the subject, it is possible that these changes in habit and routine have also affected arterial stiffness (AS) in this population, which is an important predictor of cardiovascular risk. This study aimed to assess possible changes in AS, anthropometry, and quality of life (QoL) resulting from the COVID-19 pandemic in children and adolescents. METHODS: A controlled observational cross-sectional study was performed with 193 children and adolescents aged 9 to 19 years, allocated into two groups: before the pandemic (BPG) and one year after the pandemic (APG), matched by age and sex. Cardiovascular parameters were measured non-invasively by brachial artery oscillometry with a portable device. The main AS indices evaluated were the augmentation index (AIx) and pulse wave velocity (PWV) derived from the aortic pulse wave. QoL was assessed using the Paediatric Quality of Life Inventory version 4.0 (PedsQL 4.0). RESULTS: Regarding QoL, the APG showed a worsening in emotional (p = 0.002) and school-related (p = 0.010) aspects. There was no statistically significant difference for most anthropometric parameters, except for the hip circumference, which was higher in the APG group (p < 0.001). The main predictor of AS in the paediatric population, AIx@75, was shown to be increased in the APG group (p < 0.001). Other cardiovascular parameters were also different, such as peripheral (p = 0.002) and central (p = 0.003) diastolic blood pressure, stroke volume (p = 0.010), and total vascular resistance (p = 0.002), which were shown to be decreased in the APG group, while the heart rate was increased (p < 0.001). CONCLUSIONS: Our results show that routine changes resulting from the period of social isolation increased cardiovascular risk in children and adolescents, evident by the increase in AIx@75, which is considered to be an important marker of cardiovascular risk in the paediatric population.

RESUMEN

BACKGROUND: Chronic pain is a major health and socioeconomic burden, which is prevalent in children and adolescents. Among the most widely used interventions in children and adolescents are physical activity (including exercises) and education about physical activity. OBJECTIVES: To evaluate the effectiveness of physical activity, education about physical activity, or both, compared with usual care (including waiting-list, and minimal interventions, such as advice, relaxation classes, or social group meetings) or active medical care in children and adolescents with chronic musculoskeletal pain. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, PEDro, and LILACS from the date of their inception to October 2022. We also searched the reference lists of eligible papers, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform. SELECTION CRITERIA: We included randomised controlled trials (RCTs) that compared physical activity or education about physical activity, or both, with usual care (including waiting-list and minimal interventions) or active medical care, in children and adolescents with chronic musculoskeletal pain. DATA COLLECTION AND ANALYSIS: Two review authors independently determined the eligibility of the included studies. Our primary outcomes were pain intensity, disability, and adverse events. Our secondary outcomes were depression, anxiety, fear avoidance, quality of life, physical activity level, and caregiver distress. We extracted data at postintervention assessment, and long-term follow-up. Two review authors independently assessed risk of bias for each study, using the RoB 1. We assessed the overall certainty of the evidence using the GRADE approach. We reported continuous outcomes as mean differences, and determined clinically important differences from the literature, or 10% of the scale. MAIN RESULTS: We included four studies (243 participants with juvenile idiopathic arthritis). We judged all included studies to be at unclear risk of selection bias, performance bias, and detection bias, and at high risk of attrition bias. We downgraded the certainty of the evidence for each outcome to very low due to serious or very serious study limitations, inconsistency, and imprecision. Physical activity compared with usual care Physical activity may slightly reduce pain intensity (0 to 100 scale; 0 = no pain) compared with usual care at postintervention (standardised mean difference (SMD) -0.45, 95% confidence interval (CI) -0.82 to -0.08; 2 studies, 118 participants; recalculated as a mean difference (MD) -12.19, 95% CI -21.99 to -2.38; I² = 0%; very low-certainty evidence). Physical activity may slightly improve disability (0 to 3 scale; 0 = no disability) compared with usual care at postintervention assessment (MD -0.37, 95% CI -0.56 to -0.19; I² = 0%; 3 studies, 170 participants; very low-certainty evidence). We found no clear evidence of a difference in quality of life (QoL; 0 to 100 scale; lower scores = better QoL) between physical activity and usual care at postintervention assessment (SMD -0.46, 95% CI -1.27 to 0.35; 4 studies, 201 participants; very low-certainty evidence; recalculated as MD -6.30, 95% CI -18.23 to 5.64; I² = 91%). None of the included studies measured adverse events, depression, or anxiety for this comparison. Physical activity compared with active medical care We found no studies that could be analysed in this comparison. Education about physical activity compared with usual care or active medical care We found no studies that could be analysed in this comparison. Physical activity and education about physical activity compared with usual care or active medical care We found no studies that could be analysed in this comparison. AUTHORS' CONCLUSIONS: We are unable to confidently state whether interventions based on physical activity and education about physical activity are more effective than usual care for children and adolescents with chronic musculoskeletal pain. We found very low-certainty evidence that physical activity may reduce pain intensity and improve disability postintervention compared with usual care, for children and adolescents with juvenile idiopathic arthritis. We did not find any studies reporting educational interventions; it remains unknown how these interventions influence the outcomes in children and adolescents with chronic musculoskeletal pain. Treatment decisions should consider the current best evidence, the professional's experience, and the young person's preferences. Further randomised controlled trials in other common chronic musculoskeletal pain conditions, with high methodological quality, large sample size, and long-term follow-up are urgently needed.

RESUMEN

BACKGROUND: Childhood obesity is a major cardiovascular risk factor because it predisposes individuals to comorbidities that are implicated in an increased risk of cardiovascular events. Its origin may be related to poor eating habits, such as the intake of foods of low nutritional value or inadequate eating behaviours related to emotional factors. This work aims to evaluate the relationship between the total body mass of children and adolescents and its association with eating habits, quality of life (QoL), and possible changes in early markers of cardiovascular risk. METHODS: This was a cross-sectional observational study that evaluated anthropometric and cardiovascular parameters, QoL, and eating behaviour in 181 children and adolescents aged between 5 and 13 years. Participants were stratified according to BMI/age into three groups (Adequate Weight, Overweight, and Obesity). Anthropometry included weight, height, waist and hip circumferences, waist-hip ratio, and waist-height ratio. QoL was assessed using the Peds-QL 4.0 questionnaire, and eating behaviour was assessed using the Children's Eating Behaviour Questionnaire (CEBQ). Cardiovascular parameters were assessed using the Mobil-O-Graph® device, which measures the pulse wave velocity (PWV) and augmentation index (AIx@75) to estimate arterial stiffness (AS), which is considered an early marker of cardiovascular disease. RESULTS: In addition to the increase in anthropometric measurements (p < 0.001), the Obesity group exhibited behaviour related to food intake (p < 0.05). When analysing QoL, a worsening in the social domain was also observed in the Obesity group (p < 0.05). However, PWV and AIx@75 did not differ between groups. CONCLUSIONS: Eating behaviour is related to the development of childhood obesity. However, early markers of cardiovascular risk related to AS did not change as a function of total body mass in the children evaluated.

RESUMEN

The use of fungal-based biopesticides to reduce pest damage and protect crop quality is often considered a low-risk control strategy. Nevertheless, risk assessment of mycopesticides is still needed since pests and beneficial insects, such as pollinators, co-exist in the same agroecosystem where mass use of this strategy occurs. In this context, we evaluated the effect of five concentrations of three commercial entomopathogenic fungi, Beauveria bassiana, Metarhizium anisopliae, and Cordyceps fumosorosea, by direct contact and ingestion, on the tropical stingless bees Scaptotrigona depilis and Tetragonisca angustula, temperate bee species, the honey bee Apis mellifera, and the bumble bee Bombus terrestris, at the individual level. Furthermore, we studied the potential of two infection routes, either by direct contact or ingestion. In general, all three fungi caused considerable mortalities in the four bee species, which differed in their response to the different fungal species. Scaptotrigona depilis and B. terrestris were more susceptible to B. bassiana than the other fungi when exposed topically, and B. terrestris and A. mellifera were more susceptible to M. anisopliae when exposed orally. Interestingly, increased positive concentration responses were not observed for all fungal species and application methods. For example, B. terrestris mortalities were similar at the lowest and highest fungal concentrations for both exposure methods. This study demonstrates that under laboratory conditions, the three fungal species can potentially reduce the survival of social bees at the individual level. However, further colony and field studies are needed to elucidate the susceptibility of these fungi towards social bees to fully assess the ecological risks.

RESUMEN

INTRODUCTION: Many people undergo fertility treatment to have biological children, but around four in ten patients complete all treatment cycles without having the children they desire. This triggers intense grief from which patients report taking on average 2 years to recover. Fertility guidelines and regulators stress the need to support patients through this process, but there is a scarcity of evaluated interventions to this end and evidence about when and how to offer care is lacking. This study explored patients' and healthcare professionals' (HCPs) experiences of and views about provision of psychosocial care (to patients facing unsuccessful fertility treatment, i.e., care provided by a mental health professional to address the emotional, cognitive, behavioural, relational and social needs that patients have at this stage of treatment). METHODS: Five qualitative online focus groups were conducted with Portuguese participants: three with patients waiting to initiate or undergoing their last cycle of in vitro fertilization/intracytoplasmic sperm injection or having completed it within the last 2 months without achieving a pregnancy and two with HCPs working at fertility clinics. Focus groups were recorded and transcribed verbatim, and data were analysed with Framework Analysis. RESULTS: Thirteen patients and nine HCPs participated. Analysis resulted in 1293 codes, systematically organized into 13 categories, 4 themes and 1 metatheme. The latter showed high consensus about the need for psychosocial care for unsuccessful treatment, but perceived challenges in its implementation. Themes reflected (1) consensual demand for psychosocial care at all stages of treatment but particularly at the end, (2) high perceived acceptability of integrating preventive care initiated during treatment with early psychosocial care only for those patients who experience unsuccessful treatment, (3) perceived challenges of implementing psychosocial care for unsuccessful treatment at clinics and (4) suggestions to promote its acceptability and feasibility. CONCLUSION: Patients and HCPs perceive that clinics should improve care provision across the whole treatment pathway and in particular for unsuccessful fertility treatment. Suggestions were made to inform future research focusing on the development and evaluation of psychosocial interventions to this end. PATIENT OR PUBLIC CONTRIBUTION: Patients and HCPs participated in the focus groups. Two HCPs also revised the manuscript.

RESUMEN

OBJECTIVE: To estimate the prevalence, incidence, and prognosis of back pain in children and adolescents. DESIGN: Prospective cohort study. METHODS: We followed children and adolescents between the ages of 8 and 18 years with and without back pain over 12 months (3, 6, and 12 months) from public and private schools. At baseline, parents (or guardians) answered questionnaires including sociodemographic characteristics and perception of sleep quality of their children and adolescents. Children and adolescents answered questionnaires including sociodemographic characteristics, presence of back pain, pain intensity, quality of life, and psychosomatic symptoms. At follow-up, children and adolescents answered questions about the presence of back pain. RESULTS: Six hundred fifteen children and adolescents were included, 163 of whom had back pain and 452 of whom had no back pain at baseline. The mean age of participants was 11.6 years (SD = 2.5), and the majority were female (n = 362; 59%). The 1-month prevalence of back pain was 26% (95% confidence interval: 23%-30%). The incidence rate of back pain was 35% (31%-40%) over 12 months. Of the 163 participants who had back pain at baseline, 83% had recovered by 12 months. Of those who recovered within 6 months, 31% had a recurrence of back pain at the 12-month follow-up. CONCLUSION: Two to 3 in every 10 children and adolescents reported back pain in the last month. New cases of back pain were reported by 3-4 in every 10 children and adolescents for a period of 12 months. Nearly all children recover within 12 months, but recurrence seems to be common.

RESUMEN

BACKGROUND: Psychosomatic symptoms seem to influence both the onset and development of pain. There is lack of Brazilian-Portuguese questionnaires that measure psychosomatic symptoms in children and adolescents. OBJECTIVE: To translate and cross-culturally adapt the Psychosomatic Questionnaire for Children and Adolescents into Brazilian-Portuguese and English and test the measurement properties of the Brazilian-Portuguese version. METHODS: The translation and cross-cultural adaptation (from Dutch to Brazilian-Portuguese and English) followed six steps. Interviews were conducted in 33 Brazilian children and adolescents. We also recruited 107 children and adolescents with musculoskeletal pain from schools to test the measurement properties of the Brazilian-Portuguese version. The questionnaire was completed twice with a 7-day interval. Ceiling and floor effects, missing data, internal consistency, reliability, measurement error and construct validity were assessed. RESULTS: We recruited 140 children and adolescents from public and private schools. During the cross-cultural adaptation process, no major difficulty answering and understanding the questionnaire were reported by children and adolescents. The questionnaire did not show ceiling or floor effects and had minimal missing data (0.37%). Internal consistency by the Cronbach's Alpha was 0.69. Test-retest reliability by the Intraclass Correlation Coefficient was 0.75 (95% CI: 0.64, 0.84). The smallest detectable change was 6.5 points out of 18 points. We observed a moderate correlation of 0.54 (p<0.01) with the Spence Children's Anxiety Scale, consistent with our a-priori hypothesis. CONCLUSION: The Brazilian-Portuguese version of the Psychosomatic Questionnaire for Children and Adolescents has acceptable measurement properties and is a good option for assessing psychosomatic symptoms in clinical practice and research.

RESUMEN

BACKGROUND: Low back pain is a common health condition for all ages. One quarter to a third of children report persistent pain, including low back pain. CLINICAL QUESTION: The aim of this Clinical Commentary is to provide an overview of evidence-based treatment approaches for children and adolescents with low back pain. KEY RESULTS: Physical, psychological, and pharmacological interventions are effective in reducing pain intensity and disability. Interdisciplinary and patient- and family-centered treatment approaches are the gold standard for persistent pain in children and adolescents. Communication between health professionals, children, and parents is a key part of a therapeutic alliance. The use of holistic and complementary therapies is not supported by compelling evidence. CLINICAL APPLICATION: Physical interventions can be delivered alone or as a component of other interventions. The interventions are delivered over 8 to 12 weeks. Psychological therapies are mostly delivered as a component of a multidisciplinary treatment program: cognitive behavioral therapy is most often used, and interventions usually run from 4 to 10 weeks. Pharmacological interventions should be delivered in combination with physical and psychological interventions. Tailor family-centered interventions to personal aspects, such as age, gender, and family structure. When communicating with children and adolescents, use simple language that is clear and direct. Aim to support trust between health professionals and parents to facilitate family decision making. J Orthop Sports Phys Ther 2022;52(7):419-424. Epub: 18 May 2022. doi:10.2519/jospt.2022.10768.

RESUMEN

The aim of the present transversal study was to evaluate the clinical and biochemical salivary parameters of children with and without erosive tooth wear (ETW). The study population was children aged 4 to 9 years. A trained and calibrated examiner (kappa value for intraexaminer reliability = 0.89) classified the children into ETW (n = 24) and control groups (n = 24), and applied the O'Brien index. The salivary flow rate was initially evaluated by stimulated sialometry (paraffin chewing). Afterwards, the collected saliva was submitted to biochemical analyses of pH, uric acid, total buffering capacity, ferric-reducing antioxidant power, reduced glutathione, calcium, and phosphorus. Among the ETW children, 20 (83%) had dental lesions restricted to enamel, and 4 (17%) presented lesions affecting both enamel and dentin. A statistically significant difference between the groups was obtained only for the pH values (t-test; p = 0.004), with averages of 7.31 and 7.56 for the control and the ETW groups, respectively. Considering the parameters evaluated in general, it is suggested that the salivary profile of children with ETW does not differ considerably from that of children without ETW. However, the pH mean value seems to be slightly higher in ETW children, but is still within the normal physiological range.

RESUMEN

Coronavirus disease 2019 (COVID-19) disease caused by a new coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been associated with many neurological symptoms. The purpose of this article is to describe the neurological manifestations so far reported and their probable pathogenesis. We conducted a literature review on EMBASE, MEDLINE and SCIELO databases using the terms "COVID-19", "COVID", "neurological", "neurologic", "manifestations", "implications", "Guillain-Barre syndrome", "encephalopathy". A total of 33 articles including clinical series, retrospective studies, and case reports were selected and thoroughly reviewed to describe neurological manifestations of COVID-19. There are several neurological manifestations of SARS-CoV-2 infection with different clinical presentations, severity, and prevalence. The most critical ones, such as cerebrovascular disease, encephalopathy, and Guillain-Barre syndrome, were less common and usually associated with previous medical history, known risk factors for cerebrovascular disease or advanced age. The main hypotheses for the spread of the virus are through the hematogenous route or the cribriform plate of the ethmoid bone or a disseminated severe immune response by a cytokine storm. The presence of neurological disturbances associated with laboratory tests alterations is an important clue for the physicians to promptly recognize neurological manifestations of SARS-CoV-2.

RESUMEN

Objetivo: Avaliar a alteração da rugosidade superficial de uma resina composta nanoparticulada (Filtek Z350 XT ® ) após o uso de produtos clareadores de autoaplicação contento baixa concentração de peróxido de hidrogênio. Métodos: Para isto, foram confeccionados 30 corpos de prova deste material, divididos aleatoriamente em 3 grupos com 10 amostras cada, da seguinte forma: G1 (grupo controle) no qual as amostras não foram submetidas à ação de nenhum produto clareador; G2, realização de procedimento clareador com peróxido de hidrogênio a 10% (Crest 3D White Professional Effects Whitestrips ® ) em 2 aplicações de 30 minutos, por 10 dias consecutivos; e G3, tratamento com peróxido de hidrogênio a 7,7% (pincel Pretty Smile ® ) com o mesmo número de aplicações, tempo e dias do G2. Após este período cada corpo de prova foi analisado no rugosímetro Surftest SJ-301, para determinar a sua rugosidade superficial média. Estes dados foram então submetidos à análise estatística por meio da análise de variância (ANOVA) e teste de Tukey, nível de significância de 5% para comparações múltiplas. Resultados: Ao final do experimento, houve diferenças estatísticas significantes entre o grupo controle (G1) e os demais grupos (G2 e G3), com p < 0,05. Porém, quando analisados apenas os grupos submetidos ao clareamento com o peróxido de hidrogênio em diferentes concentrações (G2 e G3), não foi encontrada diferença significativa (p > 0,05). Conclusão: Após 10 dias, os produtos clareadores testados determinaram aumento significativo nos valores de rugosidade superficial média da resina composta nanoparticulada.

Aim: Tod evaluate the change in surface roughness of a nanoparticulate composite resin (Filtek Z350 XT ® ) after using over-the-counter bleaching products, containing a low concentration of hydrogen peroxide. Methods: For this, 30 specimens of this material were made, randomly divided into 3 groups with 10 samples each, as follows: G1 (control group) in which the samples were not subjected to the action of any bleaching product; G2, performing a bleaching procedure with 10% hydrogen peroxide (Crest 3D White Professional Effects Whitestrips ® ), in 2 applications of 30 minutes, for 10 consecutive days; and G3, treatment with 7.7% hydrogen peroxide (Pretty Smile ® ), with the same number of applications, time, and days as G2. After this period, each specimen was analyzed, using the Surftest SJ-301, to determine its average surface roughness. These data were then subjected to statistical analysis through analysis of variance (ANOVA) and Tukey's Test, with a significance level of 5% for multiple comparisons. Results: Statistically significant differences were found between the control group (G1) and the other groups (G2 and G3), with p < 0.05. However, when analyzing only the groups submitted to bleaching agents with hydrogen peroxide in different concentrations (G2 and G3), no significant difference was found (p > 0.05). Conclusions: After 10 days, the bleaching products tested in this study determined a significant increase in the average surface roughness values of the nanoparticulate composite resin.

Materiales y métodos: Se evaluó la acción antimicrobiana de las pastas Guedes Pinto contra cepas aisladas de los siguientes microbios: Streptococcus mutans ATCC 25175 Staphylococcus aureus ATCC 25923, Enterococcus faecalis - ATCC 29212, Pseudomonas aeruginosa - ATCC 4116, Candida albicans ATCC 10231. Se empleó la técnica de difusión en agar por el método de pocillo y en triplicado, utilizando el digluconato de clorexidina al 0,12% como control positivo y solución salina como control negativo. Se transfirió 2 mL del inóculo producido de cada microbio a 100mL de agar fundido a 45ºC, dispensando la mezcla en 30 placas de petri. Las placas fueron mantenidas a temperatura ambiente por dos horas y luego incubadas a 35ºC por 24 y 48 horas. La lectura de los resultados fue sometida al Análisis de varianza de un factor y Test de Tukey para comparaciones múltiples. Resultados: La pasta Guedes-Pinto Convencional formó los mayores halos de inhibición para la mayoría de los microbios, con excepción de Candida albicans, donde ninguna de las sustancias produjo efecto y de la Pseudomonas aeruginosa, para la cual la pasta modificada con Diprogenta® obtuvo mejores resultados, sin diferencia estadística entre ellas. La pasta Diprogenta® presentó mejores resultados que la pasta Otosporin® para todos los demás microorganismos y esto ultimo no formó halo de inhibición para Enterococcus faecalis. Conclusión: La utilización de sustitutos de Rifocort® parece tener un potencial antimicrobiano efectivo contra los principales microbios encontrados en los canales radiculares

RESUMEN

O traumatismo dentário acontece de maneira frequente, tendo maior prevalência em incisivos centrais, podendo ocorrer de várias formas, acometendo o tecido duro e o tecido de sustentação do dente. A severidade do trauma pode ocasionar um processo degenerativo ou uma lesão irreversível até a mortificação da polpa, por isso deve-se observar o estágio de desenvolvimento do dente para correta terapêutica diante de uma rizogênese completa ou incompleta. A necrose pulpar em um dente com ápice incompleto paralisa o seu processo de desenvolvimento o que torna necessário a realização da apicificação. O objetivo desse presente trabalho é relatar um caso clínico de traumatismo em um dente com rizogênese incompleta e a conduta terapêutica instituída para promover a apicificação do mesmo. Entretanto, Durante o tratamento foi um grande desafio promover o fechamento do ápice que fora paralisado após o trauma. Portanto, foi preciso realizar várias sessões de medicação intracanal com hidróxido de cálcio que é o material mais indicado para induzir a formação de barreira calcificada para fechamento completo do ápice(AU)

The dental trauma occurs frequently, having a higher prevalence in central incisors, and can occur in several ways, affecting the hard tissue and the tooth support tissue. The severity of the trauma can cause a degenerative process or an irreversible lesion until the mortification of the pulp, so the stage of development of the tooth must be observed for correct therapy in the presence of complete or incomplete rhizogenesis. Pulp necrosis in a tooth with an incomplete apex paralyzes its development process, which makes it necessary to perform the inoculation. The objective of this present work is to report a clinical case of trauma in a tooth with incomplete rhizogenesis and the therapeutic conduct instituted to promote the apicification of the same. However, during the treatment it was a great challenge to promote the closure of the apex that had been paralyzed after the trauma. Therefore, it was necessary to perform several intracanal medication sessions with calcium hydroxide, which is the most suitable material to induce the formation of a calcified barrier for complete closure of the apex(AU)
