BackgroundStudies emphasizing toothache in adulthood are scarce in Brazil. A greater understanding of both the prevalence and the self-perception of pain among individuals in this age group (35 to 44 years old) is important, especially considering that this is an economically active population. To describe reports of oral pain and oral pain-related aspects in from Brazilian state capitals and interior cities.MethodsThe sample comprised 9779 adults residing in the state capitals and interior cities from each Brazilian region in the SB Brazil 2010 report, regarding reports of oral pain and their intensity in the last 6 months. The descriptive analysis comparing pain reports between and within the regions and regression analysis of pain related to socioeconomic aspects per region were performed considering α=0.05 difference.ResultsThe highest prevalence of pain was found in the Southeast region (p<0.01), and there was also difference between the state capitals and interior cities in the South (p<0.01), where the prevalence was higher in the capitals, and in the Southeast, where the higher prevalence was in the interior cities (p=0.03). The Northern region had lower pain intensity than the Southeast and Midwest. Comparing pain intensity, only the Northeast region showed statistical difference between state capitals and the interior cities for pain intensity, where the interior cities had higher pain intensity than the three state capitals. Regarding dental office visitations, the Southeast capitals have the highest prevalence (100%) compared to the North and South. The toothache impact on daily activities was as follows: eating difficulty (29.8% to 72.7%), uncomfortable teeth brushing (over 50%), and sleep disturbance (above 13%). Between the Brazilian regions the socioeconomic aspects differ in relation to the pain; the exception being the association between pain, dental care and income, which occurred in the 5 regions. Users of public dental care services were more likely to present pain, comparing to private dental services, OR ranging from 1.72 in the Northeast to 2.85 in the Southeast.ConclusionThe prevalence of pain was higher among Brazilian adults, impacting some of the daily activities. The data also showed many differences in the prevalence and intensity of pain among both the Brazilian regions and the cities within the same region.

Aim: To estimate tooth loss prevalence among adolescents in São Paulo, considering socioeconomic and demographic factors, dental service use and pain. Methods: Data were obtained from the São Paulo Oral Health Survey 2008. The sample comprised 2858 adolescents from 15 to 19 years old from public and private schools, who underwent through an oral examination. In addition, a questionnaire was applied regarding the characterization of factors related to socioeconomics, demographics, use of dental services and pain in the last six months. At least one tooth lost was the outcome. The independent variables included gender, ethnicity, parents' schooling, type of school, number of rooms, people and cars per home, family income, dental service use, decayed teeth, toothache. A multivariate logistic regression model was used. Results: The prevalence of tooth loss was 7%. The independent variables decayed tooth (RP=1.71), toothache (RP=2.04), father's schooling-elementary (RP=1.40) and per capita family income-less than 1/ 2 a minimum salary (RP=1.45) were associated with the outcome. Conclusions: The results suggest that socioeconomic factors may contribute to the increase of early tooth loss among adolescents.

BACKGROUND AND OBJECTIVES: Third molar extraction is an invasive and potentially adverse procedure and may induce pain. This study aimed at evaluating the efficacy of face-to-face information about postoperative pain and analgesic consumption to patients submitted to third molar extraction. METHOD: This was a longitudinal study with 123 patients randomly distributed in two groups: Control (CG) and Experimental (EG). Short form Mc Gill pain questionnaire was used (Sensory Pain Estimate Index, Affective Pain Estimate Index, Present Pain Intensity and Global Pain Experience Evaluation) in the following moments: preoperative period, immediate postoperative period, mediate postoperative period I, mediate postoperative period II and suture removal. Face-to-face information was given to EG patients immediately after the preoperative moment. Chi-square test was used for statistical analysis, mixed models were used for repeated measures (SAS program's Proc Mixed), in addition to Tukey test (α = 5%). RESULTS: Data suggest a statistically significant difference between groups in Sensory Pain Estimate Index in the immediate postoperative period, showing that immediate postoperative pain report was lower in the group receiving face-to-face information. CONCLUSION: Face-to-face information has decreased postoperative pain. These strategies are critical to establish effective coping responses and to improve postoperative adherence.

Este artigo avalia o efeito da informação prévia face-a-face sobre a ansiedade e as medidas fisiológicas de pacientes submetidos à exodontia de terceiros molares. Participaram 123 pacientes, distribuídos nos grupos: Controle e Experimental. Utilizou-se para avaliação da ansiedade: Escala de Ansiedade Odontológica de Corah e Inventário de Ansiedade Traço-Estado. A avaliação da ansiedade ocorreu nos momentos: Pré-Cirúrgico, Pós-Cirúrgico Imediato, Pós-Cirúrgico Mediato e Remoção de Sutura. A avaliação fisiológica ocorreu nos momentos: Pré-Cirúrgico, Pós-Cirúrgico Imediato e Remoção de Sutura. A informação face-a-face foi oferecida ao Grupo Experimental após o primeiro momento. Utilizou-se os testes Qui-Quadrado, Análise de Variância com Modelo Misto e Tukey (α=0,05). O resultado sugeriu não haver diferença estatisticamente significativa entre os grupos quanto à ansiedade e as medidas fisiológicas. Entretanto, a pressão arterial sistólica e diastólica e os escores de ansiedade foram menores entre os pacientes do grupo experimental, sugerindo possível efeito do procedimento preparatório.

BACKGROUND AND OBJECTIVES: The extraction of the third molar is an invasive procedure and is potentially traumatic for the patient. Preparatory procedures may be used for the management of pain and emotional responses, resulting in a better recovery process for patients. The aim of the study evaluates the effects of a preparatory procedure using an animated informative video on post-surgical pain responses after third molar extraction on youths during the postoperative follow-up. METHODS: 140 patients undergoing third molar extraction were randomly divided into two groups: control (CG) and experimental (EG). For pain assessment, the short-form McGill pain questionnaire was given once before the procedure and four times after the surgery, and the amount of postoperative analgesic consumption was recorded. The informative video was presented to the EG after the first assessment. For data analysis, ANOVA and Tukey tests (p ≤ 0.05) were used. Data analysis indicated that the EG patients reported reduced pain perception for all pain indexes. RESULTS: Significant between-group differences were observed for Sensory and Affective Rank Pain Indexes (PRI-S and PRI-A, respectively), as well as for Global Assessment, at stages 2, 3 and 4 (p=0.0001; p=0.0027; p=0.0001). For Present Pain Intensity, a significant difference between groups was observed (p=0.0004) at stages 3, 4 and 5. The postoperative consumption of analgesics was lower in the EG (p=0.0001), indicating higher medicine consumption by CG patients. CONCLUSION: The results suggest that the preoperative informative video effectively reduced pain perception and the consumption of analgesics.
