The relationship of medical and dental factors to perceived general and dental health.Richmond S, Chestnutt I, Shennan J, Brown R Dental Health and Biological Sciences, School of Dentistry, Cardiff University, Cardiff, UK. richmonds@cardiff.ac.uk OBJECTIVE: To determine the relative importance of dental and medical features in relation to perceived oral and general health in a sample of 31-year-old individuals. SUBJECTS AND METHODS: The present study used information collected from the longitudinal Cardiff Survey, which commenced in 1981. The initial sample consisted of 1018 11-year-old Caucasian schoolchildren. Three hundred and thirty-seven individuals attended the latest examination in 2001 (aged 31 years). For every individual who attended in 2001, the following information was collected: perceived general and oral health recorded on a five-point Likert scale; self-reported medical history; SF-36v(2) questionnaire; assessment of dental features; and the Index of Complexity, Outcome and Need (ICON). RESULTS: Ninety-four and 82% of individuals reported good-excellent general and oral health, respectively. Females reported a higher level of physical health than males as measured using the SF-36v( 2). Four medical conditions were associated with perceived poor general health: mental [odds ratios (OR); 95% confidence limits (95% CI): 4.5; 1.1-18.4], gastrointestinal (OR 3.4; 95% CI 1.2-9.5) and genitourinary disorders (OR 7; 95% CI 1.6-30.2), and conditions that did not readily fit into a defined category or system (OR 12.8; 95% CI 3.9-42.3). The highest prevalence of dental factors was gingivitis followed by gingival recession and plaque. Photographically assessed dental factors associated with self-reported poor/fair oral health were fillings (OR 0.45; 95% CI 0.2-0.9), root caries/abrasion (OR 0.37; 95% CI 0.1-0.9) and gingivitis (OR 0.31; 95% CI 0.1-0.9). There was a statistically significant association between oral and general health. Of those individuals reporting fair-poor oral health (18%), the proportion also reporting fair-poor general health was 63.6%. Unexpectedly, per-unit increase in ICON score was also significantly associated with fair-poor general health (OR 0.97) with clinically relevant increases of 7 ICON units producing an OR of 0.82. CONCLUSION: The relative importance of the various dental and medical conditions has been identified. Further studies are required to explore the importance of ICON in perceived medical health and importance of the various conditions on oral and general health over different age groups.
