Is there Association between Self-reported Dental visits, ToothBrushing, Fluoride use and Perceived Oral Health Status?

Objectives: Many studies have demonstrated the importance of oral health perceptions in predicting oral health behaviour. Despite the theoretical importance of this concept, the association between self-perceived oral health status and oral health practices has been given relatively little attention in Zimbabwe. The objective of this study was to examine the association between self-reported dental visit, tooth brushing, fluoride use and self-perceived oral health status. Methods: A cross sectional study was conducted and the information was collected using self-administered anonymous structured questionnaire. The sample included high school students from a boarding school in Zimbabwe. The questionnaire includes items on socio-demographic variables, knowledge of oral health, oral health behaviour and self-perceived oral health status. Self-reported dental visit, tooth brushing and fluoride use were the outcome variables. Perceived health status and selected demographic and oral health variables were taken as explanatory variables. Perceived oral health status was reported as poor, good and excellent. Result: Multivariable logistic regression revealed that dental visit was associated with selfperceived status of the teeth [OR for excellent teeth=3.8 (95% CI, 1.3, 11.0, p=0.015)] and toothache [OR=2.6 (95% CI, 1.3, 5.2, p=0.005)]. Tooth brushing was positively associated with Age [OR=1.7 (95% CI, 1.1, 2.6, p=0.011)] and self-perceived status of the teeth [OR for excellent teeth=20.6 (95% CI, 2.3, 182.3, p=0.006)]. A significant positive association was observed between fluoride use and self-perceived status of the teeth [OR for excellent teeth = 14.3 (95% CI, 2.3, 89.2, p=0.004)] after controlling for age and fluoride knowledge. Conclusion: Students with good perceived status of teeth are more likely to have regular dental visit, tooth brushing and use fluorine.
