RESUMO
INTRODUCTION: The prevalence of cervical dentin hypersensitivity in patients after corrective orthodontic treatment has been poorly studied, although such hypersensitivity is very common. This study aimed to assess the prevalence of dentin hypersensitivity in patients who received corrective orthodontic treatment, the impact of general oral problems on quality of life, and the impact of hypersensitivity on the quality of life of this population. METHODS: This observational, cross-sectional study evaluated 232 patients who finished orthodontic treatment between 2000 and 2020 for self-reported hypersensitivity and clinically diagnosed hypersensitivity. The following tests were used: tactile, evaporative (bellows), evaporative (triple syringe), and thermal. The patients were also evaluated regarding their quality of life using questionnaires (Oral Health Impact Profile-14 and Dentine Hypersensitivity Experience Questionnaire). We evaluated data with nonparametric statistics. RESULTS: The prevalence of hypersensitivity was higher in women and in those aged <30 years; the most affected teeth were the mandibular incisors and premolars; different diagnostic tests for hypersensitivity may indicate different prevalence values; patients with hypersensitivity had a lower quality of life in most of the domains of both of the tests that were used. CONCLUSIONS: The prevalence of hypersensitivity among patients after orthodontic treatment may be higher than in the general population. Further investigation is needed to indicate the possible factors associated with orthodontic tooth movement.

La hipersensibilidad de la dentina surge ante la exposición de esta y en respuesta a estímulos de diverso tipo, fundamentalmente de origen térmico, evaporativo, táctil, osmótico o químico. Se realizó una investigación abocada a caracterizar la hipersensibilidad dental de pacientes atendidos en consulta de odontología y la respuesta a determinado dentífrico utilizado. En el análisis de estimulación dental se tomaron 308 mediciones de la sensibilidad dental para todos los participantes (n=22), con 7 factores de tiempo (T0 antes del uso del producto, T3 días, T5 días, T8 días, T22 días y T29 días después del uso del dentífrico). Se realizó la prueba paramétrica regresión lineal simple para identificar la tendencia y el ajuste de los datos, al considerar dichas variables como una serie temporal. Se utilizaron 22 tratamientos. Casi el 91,0% expreso que el dentífrico había cumplido sus expectativas, fundamentalmente por la reducción de la hipersensibilidad a corto plazo, mientras que aproximadamente 91,0% de los casos afirmó que compraría el dentífrico (20 casos, IC 95%: 72,2% y 97,5%), respectivamente(AU)
Dentin hypersensitivity arises when exposed to it and in response to various types of stimuli, mainly of thermal, tactile evaporative, osmotic or chemical origin. An investigation was carried out aimed at characterizing the dental hypersensitivity of patients seen in the dental office and the response to a certain toothpaste used. In the dental stimulation analysis, 308 measurements of tooth sensitivity were taken for all participants (n = 22), with 7 time factors (T0 before use of the product, T3 days, T5 days, T8 days, T22 days and T29 days after using the toothpaste). The simple linear regression parametric test was performed to identify the trend and the fit of the data, considering these variables as a time series. 22 treatments were used. Almost 91.0% believed that the toothpaste had met their expectations, mainly due to the reduction in hypersensitivity in the short term, while approximately 91.0% of the cases stated that they would buy the toothpaste (20 cases, 95% CI: 72 , 2% and 97.5%), respectively(AU)

Introdução: A hipersensibilidade dentinária (HD) consiste em uma condição clínica caracterizada por dor localizada, curta e aguda, resultante de estímulos exógenos. Objetivo: Esse estudo objetivou realizar uma revisão da literatura sobre os aspectos relevantes vinculados à HD, como etiologia, diagnóstico, mecanismos biológicos, medidas preventivas e terapêuticas. Metodologia: Foi realizada a busca eletrônica de publicações nas bases de dados Scielo, PubMed, Periódicos Capes, Lilacs e Medline, utilizando os seguintes descritores: "dentin", "dentin sensitivy", "treatment". Os estudos foram publicados no período de 2010 a 2020. Resultados: Observou-se que a HD acomete cerca de 9-55% da população, principalmente indivíduos entre a terceira e quarta décadas de vida, apresentando maior prevalência no sexo feminino, afetando especialmente as regiões vestibulares dos caninos, pré-molares superiores e sequencialmente os incisivos e molares inferiores. O diagnóstico é determinado a partir de testes de sensibilidade, como o mecânico ou a desidratação. O tratamento dispõe de inúmeras propostas baseadas na obliteração dos túbulos dentinários como forma de impossibilitar a movimentação líquida intratubular ou restrição neural dos mecanorreceptores pulpares. Conclusão: Embora os aspectos clínicos sejam bem estabelecidos na literatura, a importância de um correto diagnóstico é essencial para um plano de tratamento adequado, por se tratar de uma condição de etiologia multifatorial...

Introduction: Dentin hypersensitivity (DH) consists of a clinical condition characterized by localized, hort and acute pain, resulting from exogenous stimulus. Objective: This study aimed to conduct a narrative literature review on the relevant aspects linked to DH, such as etiology, diagnosis, biological mechanisms, preventive and therapeutic approaches. Methodology: The electronic search for publications was carried out in the Scielo, PubMed, Capes, Lilacs and Medline databases, using the following descriptors: "dentin", "dentin sensitivy", "treatment". The studies were published in the period from 2010 to 2020. Results: It was observed that DH affects about 9-55% of the population, mainly belonging to the third and fourth decade of life, with higher prevalence in females, especially affecting the vestibular regions of the canines, upper premolars and sequentially the incisors and molars lower. The diagnosis is determined based on sensitivity tests, such as mechanical or dehydration. The treatment has numerous proposals based on the obliteration of the dentinal tubules as a way of preventing the intratubular liquid movement or neural restriction of the pulp mechanoreceptors. Conclusion: Although the clinical aspects are well established in the literature, the importance of a correct diagnosis is essential for an adequate treatment plan, as it is a multifactorial condition...

ABSTRACT: Researchers have reported false positive/negative results of the cold test in the diagnosis of pulpitis. Knowledge of the correlation between results of the cold test and proteins could aid in decreasing the frequency of incorrect diagnosis. To associate the levels of matrix metalloproteinase-8 (MMP-8) with the responses (in seconds) to the cold test in teeth diagnosed with reversible and irreversible pulpitis.A cross-sectional study was performed. A total of 150 subjects were evaluated, of which 60 subjects met the selection criteria. The participants were divided into 3 groups: Group 1, healthy pulps, 20 subjects with 20 posterior teeth (premolars) with clinically normal pulp tissue; Group 2, reversible pulpitis, 20 patients with 20 teeth diagnosed with reversible pulpitis; and Group 3, irreversible pulpitis, 20 subjects with 20 teeth diagnosed with irreversible pulpitis. All participants were evaluated based on the following variables: medical and dental history, cold test, and expression of MMP-8 by enzyme-linked immunosorbent assay in dentin samples.Responses to the cold test between 4 to 5âseconds (second evaluation; Pâ<â.0001) were associated with high levels of MMP-8 (mean, 0.36âng/mL) in the reversible pulpitis group. In the irreversible pulpitis group, the responses from 6 to ≥10âseconds (second evaluation; Pâ<â.0001) were associated with a higher average of MMP-8 levels (mean, 1.97âng/mL).We determined that an increase in the duration of response to the cold test was associated with an increase in MMP-8 levels (Rhoâ=â0.81, Pâ<â.0001) in teeth with pulpitis. The above correlations can be considered an adjunct to the clinical diagnosis of pulpitis.

The aim of the present study was to compare the sensitivity and specificity of pain scales used to assess dentin hypersensitivity (DH). The preferred scale, and toothbrushing habits of participants were also investigated. This cross-sectional study was conducted with students and employees of a Brazilian Federal University who presented DH. The participants answered a questionnaire about their toothbrushing and drinking habits. Hypersensitive and non-sensitive teeth were submitted to tactile and ice stick stimuli. Then, the subjects marked their pain level in the visual analogue (VAS), numeric scale (NS), faces pain scale (FPS) and verbal evaluation scale (VES). DH was also assessed by Schiff scale (SS). The data were analyzed by Wilcoxon and Chi-Square tests, as well as by ROC curve. The mean age of the sample (56 women, 16 men) was 27.8 years. The most prevalent acidic beverage was coffee (36.0%) and the most preferred scale was the NS (47.2%). The pain level was statistically higher in teeth with DH compared to teeth without DH (p < 0.05). The accuracy ranged from 0.729 (SS) to 0.750 (NS). The highest sensitivity value was 81.9% for NS. The SS presented the highest specificity (91%). The visual analog, numerical, verbal evaluation, faces pain, and Schiff scales were accurate for DH diagnosis. The Schiff scale was the preferred scale for DH assessment.

OBJECTIVES: To evaluate the postoperative sensitivity of restorations with self-adhesive resin composite (SAC) (Vertise Flow (VER)/Kerr) compared with conventional resin composite with self-etching adhesive (Filtek Z250 (Z250)/3M ESPE; Clearfil SE Bond (CSEB)/Kuraray). MATERIALS AND METHODS: A randomized, controlled, double-blind, split-mouth, two-arm clinical trial was conducted. Twenty-seven volunteers with third molars indicated for extraction received two deep class I restorations, one with each material. Postoperative sensitivity was measured at 24 h and 15 or 30 days after the restorative procedures using a visual analog scale (VAS). When present, information on the characteristics of the pain was also collected. The data were submitted to the McNemar test (α = 0.05). RESULTS: Regardless of the time intervals, the postoperative sensitivity was observed in 52% and 48% of the CSEB and VERT groups, respectively (p = 1.000). When the evaluation periods were analyzed, the 15-day evaluation presented the highest occurrence of pain, but of mild intensity, in both groups. All patients with sensitivity reported that the pain was localized and of short duration. CONCLUSION: Self-adhesive resin composite Vertise Flow and conventional resin composite with a self-etching bonding agent promoted similar response regarding postoperative sensitivity in deep class I cavities. When postoperative sensitivity was present, mild pain was observed, especially after 15 days of the restorative procedure, which decreased over time. CLINICAL RELEVANCE: Postoperative sensitivity to self-adhesive resin composite (SAC) restorations in deep cavities was comparable with that of conventional restorations with a self-etching bonding agent.

OBJECTIVE: This randomized controlled clinical trial aimed to evaluate the effect of the casein phosphopeptide-amorphous calcium phosphate fluoride (CPP-ACPF) and photobiomodulation (PBM) in the treatment of dentin hypersensitivity (DH), and the impact of this on the health-related quality of life (HRQL). METHODS: Eighty teeth with DH were randomized into four groups and received three treatment sessions: PLACEBO = placebo + LASER application mimicking; CPP-ACPF = CPP-ACPF + LASER application mimicking; PBM = placebo + LASER active application; CPP-ACPF+PBM = CPP-ACPF + LASER active application. Tactile (exploratory probe) and evaporative (triple syringe) stimuli were used to measure DH and were recorded with the aid of a visual analogue scale (VAS) after the 1st, 2nd and 3rd treatment sessions and one-month follow-up. The HRQL was recorded in the DH experience questionnaire (DHEQ). RESULTS: The intragroup comparison showed a significant reduction in DH (p < 0.05) with both stimuli after one-month follow-up. The intergroup comparison with the evaporative stimulus showed that CPP-ACPF+PBM significantly reduced DH when compared to the rest of treatments, after one-month follow-up. CPP-ACPF+PBM group statistically differed from the other treatment groups in the DHEQ evaluation after one-month follow-up. CONCLUSION: After one-month follow-up, the association of CPP-ACPF with PBM was effective in the reduction of DH and promoted a positive impact on the HRQL of the participants of this study.

OBJECTIVE: This study aimed to identify and compare the self-reported and diagnosed prevalence of dentinal hypersensitivity (DH) in an University population; and to verify accuracy, sensitivity and specificity of DH stimuli tests. MATERIAL AND METHODS: Three hundred and eighty patients (67.2% women and 32.8% men) were assessed by questionnaire, clinical exam, tactile and cold water tests. The intensity of DH was assessed using a visual analogue scale, and a calibrated examiner measured the scores using a caliper. The ICC for intra-examiner was 0.990. Scores above 5 mm were considered sensitive teeth. The association between variables was assessed by Chi-square test. ROC curve analysis determined accuracy, sensitivity and specificity of the tests (p < .05). RESULTS: The mean age of participants was 24.08 years. 158 (41.7%) volunteers self-reported the presence of DH, while, 88.7% of the participants were clinically diagnosed (p = .023). In total, 8958 teeth were evaluated, of those 3367 (37.6%) were diagnosed sensitive. The most prevalent teeth with DH were incisors and premolars. The accuracy of the tests with cold water and tactile were 99%. The sensitivity and specificity for cold water and tactile tests were 99.9%, 99.7%, 99.1% and 87.6%, respectively. CONCLUSION: The self-reported prevalence of DH was significantly lower than that clinically diagnosed. The cold test proved to be a highly accurate stimulus for the diagnosis of DH.

La exposición de dentina radicular asociada a una recesión gingival puede producir dolor ante distintos estímulos, situación que puede difi cultar la vida cotidiana de los pacientes que lo padecen, además de presentar complicaciones estéticas que pueden afectar la autoestima. La hipersensibilidad dentinaria tiene una etiología asociada a múltiples factores, siendo el principal factor de riesgo la recesión gingival, situación clínica común que se observa en gran parte de la población. El propósito de esta revisión es reunir distintos conceptos que expliquen la asociación que mantienen estas dos patologías, sus etiologías, el cuadro clínico que presenta la hipersensibilidad dentinaria para poder realizar un diagnóstico diferencial y las distintas opciones de tratamiento para realizar un adecuado manejo de esta condición que incluyen desde recursos terapéuticos que buscan resolver la sintomatología hasta procedimientos quirúrgicos que resultan más invasivos y que se enfocan en tratar el factor predisponente como es la recesión gingival misma (AU)

BACKGROUND: This cross-sectional study aimed to identify the factors associated to the cervical dentin hypersensitivity (DH) in Brazilian adult population. METHODS: Three hundred and eighty patients (67.2% women and 32.8% men) were assessed by questionnaire and thermal test with ice. Participants marked in a visual analogue scale (VAS) the intensity of pain, and a calibrated examiner (ICC 0.990) measured the scores using a caliper. Pain scores above 0.5 mm were considered sensitive teeth. The DH associated factors were investigated by clinical examination. The association between variables was assessed by Spearman correlation and the Chi-square test. Logistic regression was used to determine the variables that predict DH (p < 0.05). RESULTS: The mean age of participants was 24.08 years. In this population, 8958 teeth were evaluated, of those 3037 (33.9%) were diagnosed sensitive. The most prevalent associated factors to DH were abnormal tooth positioning (9.0%), occlusal trauma (6.5%) and gingival recession (5.6%). The erosion predicted significantly the DH on both simple (OR 7.85, p < 0.001) and multiple(OR 4.36, p < 0.001) analysis. CONCLUSION: The exposure of dentinal tubules by erosion is probably the major predictor of dentin hypersensitivity. The healthy tooth is able to protect against DH.

The dentine hypersensitivity (DH) is able to impair the oral health related quality of life (OHRQoL). However, there isn't any specific validated questionnaire to be used in Brazil. The objective was to adapt and to validate the English version of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15) for use in Brazil. DHEQ-15 was cross-culturally adapted into the Brazilian-Portuguese language and then validated in a cross-sectional study with 100 participants recruited at a University clinic. Study sample comprised 2 groups: 100 individuals with DH, and 100 individuals without. The instrument was self-administered twice 7 to 10 days apart. The participants answered a global rating of oral health. The psychometric properties of the Brazilian version of DHEQ-15 were verified through internal consistency (Cronbach's α) and test-retest reliability (intraclass correlation coefficient - ICC), convergent (Spearman correlation) and discriminant (Mann-Whitney test) validity. The significance threshold was set at p<0.05. Sample comprised 69 men and 131 women, of mean age 30.4y. The Brazilian DHEQ-15 demonstrated very good internal consistency (α = 0.945). Test-retest reliability revealed excellent reproducibility (ICC = 0.959, p < 0.001). There was statistically significant correlation between the scores obtained on all DHEQ-15 domains and the global rating of oral health (p<0.001). Participants with DH scored significantly higher than those without DH (p<0.001). This study provides evidence supporting the cross-cultural validity of the Brazilian version of DHEQ-15 for use in Brazil.

Objective The objective of this study was to evaluate dental sensitivity using visual analogue scale, a Computerized Visual Analogue Scale (CoVAS) and a neurosensory analyzer (TSA II) during at-home bleaching with 10% carbamide peroxide, with and without potassium oxalate. Materials and Methods Power Bleaching 10% containing potassium oxalate was used on one maxillary hemi-arch of the 25 volunteers, and Opalescence 10% was used on the opposite hemi-arch. Bleaching agents were used daily for 3 weeks. Analysis was performed before treatment, 24 hours later, 7, 14, and 21 days after the start of the treatment, and 7 days after its conclusion. The spontaneous tooth sensitivity was evaluated using the visual analogue scale and the sensitivity caused by a continuous 0°C stimulus was analyzed using CoVAS. The cold sensation threshold was also analyzed using the TSA II. The temperatures obtained were statistically analyzed using ANOVA and Tukey's test (α=5%). Results The data obtained with the other methods were also analyzed. 24 hours, 7 and 14 days before the beginning of the treatment, over 20% of the teeth presented spontaneous sensitivity, the normal condition was restored after the end of the treatment. Regarding the cold sensation temperatures, both products sensitized the teeth (p<0.05) and no differences were detected between the products in each period (p>0.05). In addition, when they were compared using CoVAS, Power Bleaching caused the highest levels of sensitivity in all study periods, with the exception of the 14th day of treatment. Conclusion We concluded that the bleaching treatment sensitized the teeth and the product with potassium oxalate was not able to modulate tooth sensitivity.

Abstract A test frequently used to complement endodontic diagnoses is the cold test; however, in the last 20 years, authors have reported incorrect results within pulp sensitivity tests. Specifically, a high frequency of false results in posterior teeth, were found. The aim of this study was to identify the most appropriate site for the cold test in molar teeth with a need for endodontic treatment, calculating predictive values, accuracy and reproducibility. A cross-sectional study was performed, evaluating 390 subjects. A total of 152 subjects of both genders from the ages of 15-65 years old participated. The ideal standard was established by direct pulp inspection, and the cold test agent used was 1,1,1,2-tetrafluoroethane. The patients were divided into four groups in relation to the molar tooth: (1) mandibular first molar, (2) mandibular second molar, (3) maxillary first molar, and (4) maxillary second molar. 169 teeth and 676 sites were studied. (a) The most appropriate sites for cold test were the middle third of the buccal surface and cervical third of the buccal surface in the mandibular molars with the following results: Middle third of the first molar: Accuracy 0.93, positive predictive value 0.90 and negative predictive value 0.96. Middle third of the second molar: Accuracy 0.93, positive predictive value 1.00 and negative predictive value 0.90. In relation to third cervical the results were: First molar: Accuracy 0.93, positive predictive value 0.89 and negative predictive value 0.97 y second molar: Accuracy 0.93, positive predictive value 1.00 and negative predictive value 0.90. (b) The highest reproducibility was observed in the middle third of the buccal surface with cervical third of the buccal surface in the mandibular second molar (1.00). The most appropriate site and reproducibility of the sites are auxiliary to complement endodontic diagnose with the cold test.
Resumen Una prueba frecuentemente utilizada para complementar los diagnósticos endodónticos es la prueba de frío. Sin embargo, en los últimos 20 años, los autores han reportado resultados incorrectos con las pruebas de sensibilidad pulpar. Específicamente, se ha observado una alta frecuencia de resultados falsos en dientes posteriores. El objetivo del estudio fue identificar el sitio más adecuado para la prueba de frío en dientes molares con necesidad de tratamiento endodóntico, calculando valores predictivos, exactitud y reproducibilidad. Se realizó un estudio transversal donde se evaluaron a 390 sujetos. 152 sujetos de ambos sexos de 15 a 65 años cumplieron con los criterios de inclusión. El estándar ideal que se utilizó en el estudio fue la inspección directa de pulpa en la cámara pulpar y la prueba de frío utilizada fue el 1,1,1,2-tetrafluoroetano. Los pacientes fueron divididos en cuatro grupos en relación al diente molar: (1) primer molar mandibular, (2) segundo molar mandibular, (3) primer molar maxilar, y (4) segundo molar maxilar. En el estudio se evaluaron 169 dientes con 676 sitios. (a) Los sitios más adecuados para la prueba de frío fueron el tercio medio y el tercio cervical de la superficie bucal en los molares mandibulares con los siguientes resultados: Tercio medio del primer molar: Exactitud 0.93, valor predictivo positivo 0.90 y valor predictivo negativo 0.96. Tercio medio del segundo molar: Exactitud 0.93, valor predictivo positivo 1.00 y valor predictivo negativo 0.90. En relación al tercio cervical los resultados fueron: Primer molar: Exactitud 0.93, valor predictivo positivo 0.89 y valor predictivo negativo 0,97 y segundo molar: Exactitud 0.93, valor predictivo positivo 1.00 y valor predictivo negativo 0.90. (b) La más alta reproducibilidad (1.00) se observó entre el tercio medio con el tercio cervical de la superficie bucal en el segundo molar inferior. El sitio más apropiado y la reproducibilidad de los sitios son auxiliares para complementar el diagnóstico endodóntico con la prueba de frío.

Objective: To determine the frequency of sensitivity after treatment in composite resin restorations Class II of premolars in Iranian patients. Material and Methods: In this descriptive-cross-sectional study, questionnaires were used which included questions about the extent of post-operative sensitivity in posterior composite resin restorations among 178 patients referred to the restoration section. After restoration of the teeth, the patients were called to record sensitivity after the treatment. Post-operative sensitivity was measured 24 h and 1 month with cold stimulation using Visual Analog Scale (VAS) method. The data were analyzed with the SPSS software, through descriptive statistical methods (frequency and percentage, mean, standard deviation). Group comparisons were evaluated using Mann-Whitney U test and p-value <0.05 was considered to be statistically significant. Results: The mean frequency of sensitivity in terms of gender was 0.75 and 0.76 in males and females, respectively. The mean frequency of sensitivity in terms of type of jaw was 0.59 and 1.1, in the upper and lower jaw, respectively. It was also observed that the frequency of sensitivity is higher in adolescent age group, in comparison with other age groups. No significant association between gender as well as type of jaw and post-operative sensitivity frequency was observed (p>0.05). However, age group has a statistically significant association with the frequency of post-operative sensitivity (p<0.05). Conclusion: There is a significant relationship between extent of sensitivity after treatment in composite resin restorations Class II and the age group of patients.

Abstract Objective The objective of this study was to evaluate dental sensitivity using visual analogue scale, a Computerized Visual Analogue Scale (CoVAS) and a neurosensory analyzer (TSA II) during at-home bleaching with 10% carbamide peroxide, with and without potassium oxalate. Materials and Methods Power Bleaching 10% containing potassium oxalate was used on one maxillary hemi-arch of the 25 volunteers, and Opalescence 10% was used on the opposite hemi-arch. Bleaching agents were used daily for 3 weeks. Analysis was performed before treatment, 24 hours later, 7, 14, and 21 days after the start of the treatment, and 7 days after its conclusion. The spontaneous tooth sensitivity was evaluated using the visual analogue scale and the sensitivity caused by a continuous 0°C stimulus was analyzed using CoVAS. The cold sensation threshold was also analyzed using the TSA II. The temperatures obtained were statistically analyzed using ANOVA and Tukey's test (α=5%). Results The data obtained with the other methods were also analyzed. 24 hours, 7 and 14 days before the beginning of the treatment, over 20% of the teeth presented spontaneous sensitivity, the normal condition was restored after the end of the treatment. Regarding the cold sensation temperatures, both products sensitized the teeth (p<0.05) and no differences were detected between the products in each period (p>0.05). In addition, when they were compared using CoVAS, Power Bleaching caused the highest levels of sensitivity in all study periods, with the exception of the 14th day of treatment. Conclusion We concluded that the bleaching treatment sensitized the teeth and the product with potassium oxalate was not able to modulate tooth sensitivity.

Objective:To evaluate the prevalence of postoperative pain and its intensity in association with clinical factors in patients undergoing root canal treatment. Material and Methods:50 subjects over 18 years of age of both genders were included by demand. Questionnaires were applied to subjects in order to obtain demographic data, clinical features about presence of pain and its intensity at intervals of 24 and 48 hours after procedure. Teeth were treated by the crown-down technique in single or multiple visits, aided by irrigation with 2.5% sodium hypochlorite, proceeding to the filling of root canals by the Tagger's hybrid technique, using gutta-percha and zinc oxide-eugenol cement. Data were analyzed with univariate and bivariate statistical test (Fisher's exact test) using SPSS 13.0 software. Results:No statistical difference (p>0.05) was observed between prevalence of postoperative pain and its magnitude in association with clinical variables. Conclusion:Pulp sensitivity (vitality), pre-existence of apical lesion, single-session treatment, use of intracanal dressing, reported pain prior to treatment, and use of analgesic medication were not associated with the prevalence of postoperative pain

O nível de sensibilidade de cada voluntário foi avaliado através da escala visual analógica de dor (VAS) com auxílio do ar da seringa tríplice e exploração com sonda após 12 e 18 meses do tratamento. Na parte 02, in vitro, foram utilizados terceiros molares humanos não irrompidos e recém-extraídos. Todos foram limpos e tiveram suas raízes separadas das coroas. As raízes foram seccionadas em quadrados de dentina com dimensões de 4x4x2 mm, os quais foram embutidos em resina Epoxi e devidamente polidos até uma curvatura de 0,3 ?m, analisados em perfilometria ótica. Estes foram imersos em solução de EDTA 17% por 2min para abertura dos túbulos e armazenados em uma solução de Soro Fetal Bovino diluído em salina tamponada com fosfato. Os espécimes foram divididos aleatoriamente em 12 grupos (n=10) G1: Sem tratamento de superfície, sem dentifrício; G2: Nd:YAG/sem dentifrício; G3: Gluma/sem dentifrício; G4: Nd:YAG + Gluma/sem dentifrício; G5: Sem tratamento de superfície/Colgate Total 12; G6: Nd:YAG/Colgate Total 12; G7: Gluma/Colgate Total 12; G8: Nd:YAG + Gluma/Colgate Total 12; G9: Sem tratamento de superfície/Colgate Pró Alívio; G10: Nd:YAG/Colgate Pró Alívio; G11: Gluma/Colgate Pró Alívio; G12: Nd:YAG + Gluma/Colgate Pró Alívio. Em seguida, as superfícies receberam a aplicação de fitas adesivas nas duas margens, mantendo uma área central de teste exposta de 4 x 1 mm, onde foram realizados os tratamentos de superfície e os ciclos de abrasão correspondentes a 1, 7, 30 e 90 dias de escovação (52 ciclos, 210 segundos de contato com o slurry; 361 ciclos, 1470 segundos de contato com o slurry; 1545 ciclos, 6300 segundos de contato com o slurry; 4635 ciclos, 18900 segundos de contato com o slurry, respectivamente). A cada etapa de abrasão, foi realizada análise em Perfilometria Ótica. Para as analises de permeabilidade e Microscopia Eletrônica de Varredura, foram utilizadas amostras circulares de 6 mm de diâmetro e 1 mm de espessura de dentina...
