Objective: To determine the dental treatment needs of Canadians and how they are distributed. Methods: A secondary analysis of data from the Canadian Health Measures Survey was undertaken. Weights were applied to make the data nationally representative. Bivariate and multivariate regressions were used to identify predictors of need. Sensitivity, specificity, positive and negative predictive values were calculated to compare self-reported and clinically determined needs. Results: Of the 34.2% who required dental treatment, most needed restorative (20.4%) and preventive (13.7%) care. The strongest predictors of need were having poor oral health, reporting a self-perceived need for treatment and visiting the dentist infrequently. A discrepancy was found between clinical and self-reported needs. Conclusions: Roughly 12 million Canadians have unmet dental needs. A number of factors are predictive of having unmet dental conditions. Program and policymakers now have information by which to assess if their programs match the dental needs of Canadians.MAS
