Aim: To investigate the caries status of, and the delivery of care to, a group of regularly attending adolescent dental patients. To conduct research in primary dental care. A subsidiary aim was to compare the caries status of this sample to population samples.
Setting: General dental practices across Scotland.
Design: A 3-year cohort study.
Subjects: 41 volunteer general dental practitioners and 616 adolescent patients (mean age = 12.1 years at baseline) defined by the practitioners as 'regular' attenders.
Results: All practices remained in the study. 403 subjects were seen at both baseline and final examination and 329 were examined at all 4 annual examinations. The mean D3MFT (dentine caries threshold) was 1.8 at baseline and 3.9 at the final examination, three years later. Of the 541 subjects seen at baseline 62% had experienced either restored or unrestored dentinal caries. Thirty-four percent of all those examined at baseline had all the unrestored dentinal caries. The majority of the disease was to be found in the molar teeth, particularly the first permanent molars. The provision of sealants was relatively high with 85% of subjects having at least one sealed tooth by the final examination. Although disease levels were related to socio-economic status, the Care Index was not.
Conclusions: The 'regularly attending' subjects had a better normative level of dental health than their peers in the Scottish population. However, wide variation was found. The project also demonstrated the feasibility of undertaking research in partnership with general dental practitioners.
