The relationship between general health and lifestyle factors and oral health outcomes

Aim The primary research question addressed in this paper was 'are lower than average oral health scores observed for those patients who report problems with general health and high-risk lifestyle factors?' Methods A population analysis was conducted on the first 37,330 patients, assessed by 493 dentists in the UK, to receive a Denplan PreViser Patient Assessment (DEPPA) at their dental practice. The Oral Health Score (OHS) was generated using a mixture of patient-reported factors and clinical findings and is an integrated component of DEPPA. Patients' self-reported risk factors included diabetes status, tobacco use and alcohol consumption. Patients' general health was measured by self-report, that is, a yes/no answer to the question 'have you experienced any major health problems in the last year for example a stroke, heart attack or cancer?' Multivariable linear regression analysis was employed to study the association between the OHS and general health and risk factors for patients in the DEPPA cohort. Results The mean age of participants was 54 years (range 17-101; S.D. 16 years) and the mean OHS for the group was 78.4 (range 0-100; S.D. 10). 1,255 (3%) of patients reported experiencing a major health problem in the previous year. In the fully adjusted model, diabetes, tobacco use, excessive alcohol consumption (three or more drinks per day), and poor overall health in the preceding year were all associated with a statistically significant drop in the mean OHS of patients. Having diabetes was associated with a 1.7 point (95% CI 1.3-2.1, P < 0.001) drop in OHS, tobacco use was associated with a 2.7 point (95% CI 2.5-2.9, P < 0.001) drop in OHS, and excessive alcohol consumption was associated with a 1.8 point (95% CI 1.3-2.4, P < 0.001) drop in OHS. The mean OHS in patients who reported a major health problem in the preceding year was 0.7 points (95% CI 0.2-1.2, P = 0.006) lower than that of patients who did not report a major health problem in the preceding year. Conclusion The current study has demonstrated that patient reported general health and risk factors were negatively associated with an overall composite oral health score outcome in a large population of over 37,000 patients examined by 493 dentists. While the clinical significance of some of the reported associations is unknown, the data lend support to the growing body of evidence linking the oral and systemic health of individuals. Therefore, GDPs may be in a unique position to influence the lifestyle and general health of patients as part of their specific remit to attain and maintain optimal oral health.
