RESUMEN

BACKGROUND: Dental anxiety is a common issue among adolescents. Despite the use of smartphones being an important part of their daily lives, only a few digital-based interventions for dental anxiety have been tested in randomized controlled trials (RCT). AIM: The aim of this study was to evaluate a new smartphone application (App) named FALE, which was designed to demonstrate interest from the dentist to adolescent and to reduce dental anxiety. DESIGN: This is a RCT in which 184 adolescents aged 10-19 years were randomly allocated into the intervention group (IG) or the control group (CG). The intervention was applied in the waiting room before the consultation at a dental clinic. The IG answered the FALE, which contained 14 questions-of which the first and last questions addressed anxiety, whereas the CG answered the question about anxiety twice with an interval between them. RESULTS: There was a significant difference in the distribution of anxiety rating frequencies before and after the intervention period in both groups. For the IG, there was a reduction in anxiety after the intervention of 16.29%, and, in the CG, a reduction of 2.2% (p < .001). CONCLUSION: The FALE App effectively reduced dental anxiety before the appointment.

RESUMEN

BACKGROUND: Temporomandibular disorders (TMDs) are multifactorial, and high levels of stress seem to increase symptoms. The association with exposure to violence has not been explored in adolescent populations. OBJECTIVE: To examine the association of self-reported symptoms of temporomandibular pain and jaw dysfunction with child physical abuse, intimate partner violence, forced sexual intercourse, and bullying victimisation. METHODS: An epidemiological, cross-sectional, school-based study was conducted in Olinda, northeast Brazil. The sample comprised 2,431 adolescents aged 14-19 years. TMD-related symptoms and exposure to violence were assessed with questions from the 3Q/TMD screener and queries on exposure to different forms of violence. Multilevel logistic regressions were conducted to evaluate how 3Q screen-positive responses are associated with self-reported exposure to violence. RESULTS: Self-reported TMD-related symptoms had a prevalence of 40.5%. Significantly more females than males screened positive to all 3Q/TMD questions (p < .001). Adolescents experiencing intimate partner violence (p = .012) and bullying (p < .001) had significantly higher odds of 3Q positive responses than those who reported no exposure to violence. Significant associations of TMD-related symptoms with forced sexual intercourse (p = .014) and with bullying (p = .007) were observed. CONCLUSION: Adolescents with self-reported symptoms of temporomandibular pain and jaw dysfunction were significantly more often exposed to some type of violence. The number of adolescents reporting TMD-related symptoms increased in a dose-response manner with the number of violence forms the individual had experienced.

RESUMEN

ABSTRACT Objective: To translate, perform a cross-cultural adaptation and reliability analysis of the Survey of Anxiety and Information for Dentists (SAID) for use with Brazilian adolescents. Material and Methods: The SAID was translated into Brazilian Portuguese and back-translated to English. An expert committee compared both versions and examined their equivalence. Then, a face validation was performed with 10 adolescents. The SAID was applied in printed format with 25 questions. Participants answered and commented on the questions with a researcher to confirm the understanding and provide suggestions. The suggestions were implemented, and the expert committee approved the final version of the SAID in Brazilian Portuguese. The psychometric properties were tested with 60 adolescents aged 10 to 19 years. Participants answered the Brazilian version of the SAID before their first dental appointment and two weeks later to determine test-retest reliability. Reliability was analyzed by internal consistency analysis (Cronbach's alpha) and test-retest (ICC). Results: The instrument presented excellent reliability according to internal consistency (Cronbach's alpha = 0.77) and test-retest coefficients (ICC = 0.88; 95% CI: 0.81-0.93). The Kappa coefficients and the degree of agreement of the dichotomous questions indicated good reproducibility of the new version. Conclusion: The SAID translation, cross-cultural adaptation and reliability analysis were completed successfully. Thus, the Brazilian version of the SAID can be a useful survey tool for dental care of adolescent patients.

RESUMEN

Introdução: A ansiedade odontológica interfere nos cuidados com a saúde bucal, causa resistência em ir ao consultório odontológico e dificulta o trabalho do cirurgião-dentista. Objetivo: determinar a prevalência de ansiedade relacionada ao tratamento odontológico em adolescentes, por meio de uma revisão da literatura. Material e método: Revisão da literatura, realizada através da busca ativa de informações na "Biblioteca Virtual em Saúde" (bvsalud.org) nas bases de dados MEDLINE e LILACS, totalizando a produção bibliográfica de um período de 25 anos. Foram adotados os seguintes descritores: "ansiedade ao tratamento odontológico" e "prevalência", de forma integrada. Foram incluídos estudos originais que avaliaram prevalência de ansiedade ao tratamento odontológico, conduzidos com indivíduos entre 10 e 19 anos de idade, com amostra representativa da população estudada. A busca foi limitada a publicações nos idiomas inglês, português ou espanhol; e do tipo artigo científico. A metodologia seguiu as recomendações PRISMA. Resultados: Foram identificados 7 artigos preenchendo os critérios de inclusão. A prevalência de ansiedade relacionada ao tratamento odontológico variou de 6,5 a 25,6% entre adolescentes, distribuídos entre Europa, Ásia e Oceania. Houve também diversidade de instrumentos utilizados para avaliação da ansiedade. Conclusão: A prevalência de ansiedade relacionada ao tratamento odontológico apresentou grande variabilidade entre as pesquisas analisadas, podendo chegar a » dos adolescentes. Observou-se uma carência de estudos de prevalência consistentes nessa faixa etária(AU)

Introduction: Dental anxiety interferes with oral health care, causes resistance to going to the dental office and hinders the work of dentists. Objective: to determine the prevalence of dental anxiety in adolescents, by means of a review of the literature. Material and method: Integrative review of the literature, conducted by active search in the "Virtual Health Library" (bvsalud.org) in the MEDLINE and LILACS databases, retrieving the bibliographic production in a period of 25 years. The following keywords were selected: "dental anxiety" and "prevalence", combined in an integrated manner. Original studies that evaluated the prevalence of dental anxiety were included, conducted in subjects aged between 10 to 19 years, with a representative sample of the studied population. The search was limited to publications in English, Portuguese and Spanish languages and scientific article type. The methodology followed the PRISMA recommendations. Results: Seven articles that fulfilled the inclusion criteria were identified. The prevalence of dental anxiety ranged from 6.5 to 25.6% among adolescents, which varied across the countries Europe, Asia and Oceania. Several instruments were used to evaluate dental anxiety. Conclusion: The prevalence of dental anxiety presented great variability among the analyzed studies, reaching up to 1/4 of the adolescents. There was a lack of consistent prevalence data in this age group(AU)
