Dental fear association between mothers and adolescents-a longitudinal study.

ABSTRACT: Aim:To assess the longitudinal association between adolescents' and their mothers' dental fear. Study Design:A longitudinal questionnaire survey study. Methods:A randomized sample of 12-year-old adolescents were selected from local Hong Kong schools. Adolescents and their mothers self-completed the Modified Dental Anxiety Scale (MDAS). The sociodemographic background of the mothers and the oral health habits of the adolescents were also collected and these measurements were repeated at 15- and 18-years-old. Non-parametric tests (Mann-Whitney U test/Kruskall Wallis test) were used to test associations between MDAS dental fear items and independent variables. Logistic regression (adjusted for family's sociodemographic background and adolescent's oral health habits) was performed to evaluate the longitudinal association between adolescents' and mothers' dental fear. Results:A total of 212 mother-child pairs were recruited at baseline (12-year-old adolescents). In the first and second follow-ups (15- and 18-years-old), 195 and 182 mother-child pairs completed the survey. Significant associations between mother's and child's scores in "feeling about having their teeth scraped and polished", "having teeth drilled", and 'having an injection in the gum' were found when adolescents were 12- years-old (P < 0.01) and 18-years-old (P < 0.05), but not at 15-years-old. Conclusion:Adolescents' and mothers' dental fear is associated at 12-years-old and 18-years-old, but not at 15-years-old, which is likely specific to the Hong Kong context but may be extrapolated to other industrialized countries with caution.

Project description:Fear of pain is experienced in acute and chronic pain populations, as well as in the general population, and it affects numerous aspects of the orofacial pain experience, including pain intensity, pain-related disability, and pain behavior (e.g., avoidance). A related but separate construct-dental fear-is also experienced in the general population, and it influences dental treatment-seeking behavior and oral and systemic health. Minimal work has addressed the role of genetics in the etiologies of fear of pain and dental fear. Limited available data suggest that variants of the melanocortin 1 receptor (MC1R) gene may predict greater levels of dental fear. The MC1R gene also may be etiologically important for fear of pain. This study aimed to replicate the finding that MC1R variant status predicts dental fear and to determine, for the first time, whether MC1R variant status predicts fear of pain. Participants were 817 Caucasian participants (62.5% female; mean ± SD age: 34.7 ± 8.7 y) taking part in a cross-sectional project that identified determinants of oral diseases at the community, family, and individual levels. Participants were genotyped for single-nucleotide polymorphisms on MC1R and completed self-report measures of fear of pain and dental fear. Presence of MC1R variant alleles predicted higher levels of dental fear and fear of pain. Importantly, fear of pain mediated the relation between MC1R variant status and dental fear (B = 1.60, 95% confidence interval: 0.281 to 3.056). MC1R variants may influence orofacial pain perception and, in turn, predispose individuals to develop fears about pain. Such fears influence the pain experience and associated pain behaviors, as well as fears about dental treatment. This study provides support for genetic contributions to the development/maintenance of fear of pain and dental fear, and it offers directions for future research to identify potential targets for intervention in the treatment of fear of pain and dental fear.
