Abstract
Introduction: The study aimed to assess the direct and indirect effect of parental locus of control (LoC) on child oral health-related quality of life.
Methods: As part of the Growing Up in Singapore towards Healthy Outcomes (GUSTO) multicenter longitudinal cohort study, sociodemographic characteristics of parents and their children were obtained at recruitment. Oral health status and dental caries outcomes were assessed at the 5th year post-natal visit and administered alongside the LoC questionnaire. Intraoral examinations were carried out by 3 trained calibrated dental professionals using the modified International Caries Detection and Assessment System (ICDAS-II) criteria. At the 6-year post-natal visit, the Early Childhood Oral Health Impact Scale (ECOHIS) was administered to mothers to assess the oral health-related quality of life (OHRQoL) of their child. Statistical analysis of the direct effects of parental LoC on OHRQoL and the causal mediation effects of dental caries were carried out using the potential outcomes approach with 1,000 simulations.
Results: A total of 312 parent-child dyads were included in this prospective cohort study. At the 5th year post-natal visit, the median decayed, missing, and filled surfaces (dmfs) was 2 (IQR 0-5), while the median LoC was 47 (IQR 43-50). The total effect of parental LoC on ECOHIS was -2.05 (95% CI: -4.03 to -0.08), of which the direct effect through dmfs was -1.45 (95% CI: -3.41 to 0.47). The percentage of the total effect of parental LoC on ECOHIS that was mediated by the presence of dental caries was 29.5% for dmfs, including incipient caries (ICDAS 1-6). The proportion mediated was lower if only active decayed surfaces were considered (23.7%) and higher if only cavitated lesions (ICDAS 3-6) (30.1%) were considered.
Conclusion: The effect of parental LoC on child OHRQoL was mediated in part through the development of dental caries.
期刊介绍：
''Caries Research'' publishes epidemiological, clinical and laboratory studies in dental caries, erosion and related dental diseases. Some studies build on the considerable advances already made in caries prevention, e.g. through fluoride application. Some aim to improve understanding of the increasingly important problem of dental erosion and the associated tooth wear process. Others monitor the changing pattern of caries in different populations, explore improved methods of diagnosis or evaluate methods of prevention or treatment. The broad coverage of current research has given the journal an international reputation as an indispensable source for both basic scientists and clinicians engaged in understanding, investigating and preventing dental disease.
