Abstract

Few studies have reported the role of motivation in patient adherence to dental-care programmes or dental home care and prevention of oral disease, particularly in Indonesia. Objective: To cross-adapt the Self-Regulation for Dental Home Care Questionnaire (SRDHCQ) to the Indonesian version, and to study self-regulation for dental home care among adolescents. Methods: The SRDHCQ was cross culturally adapted to the Indonesian adolescents aged 12-13 years old to test its reliability and validity. Intraoral examination was conducted by a single examiner to analyse the number of decayed teeth. The SRDHCQ contains 22 questions with a 7-point scale, which comprises of integrated, identified, introjected, external regulation and amotivation domains. Respondents were randomly selected from 11 junior high schools at six districts in Jakarta. Results: Total respondents studied were 317 students, with prevalence of 71% of the students having decayed teeth, and average number decayed teeth was 2.1. The test and test-retest reliability and Cronbach’s alpha for internal consistency were 0.838 and 0.929, respectively. No significant difference was observed in total SRDHCQ scores between genders. Construct and discriminant validity analysis showed significant results. Conclusions: Our results support the reliability and validity of the Indonesian SRDHCQ for adolescents in Indonesia.

Abstract

Introduction: The masseter and the anterior part of the temporalis are the muscles mainly responsible for the clenching function. Clenching patterns and the activity of these muscles are not expected to differ between male and females, nor between different occlusal classes. Objective: The aim of this study was to determine whether the activity index of the masseter and temporalis muscles is related to occlusal class and gender. Methods: This study involved 145 eighteen-year-old Caucasian volunteers who underwent surface electromyography. The sEMG was analyzed at the moment of 100% occlusal contact. Occlusal classes were determined used plaster casts. Results: The Class I group contained 34 males and 63 females, while Class II had 11 males and 25 females. Comparison of the AcI data showed an insignificant relation between the genders in the activity indices of Classes I and II. Significant relation between male gender and predominance of the masseter muscles, as well as between female gender and an almost equal balance between the muscles, though with a tendency towards a predominance of the temporalis anterior. Conclusion: The activity of masseter muscles during clenching the teeth is bigger in the male than in the female group. Activity index is related to gender.
