Background:
The objective of this research was to assess the efficacy and cost-effectiveness of a non-invasive approach to dental caries management in private dental practice.
Methods:
Private dental practices from a variety of locations in New South Wales were randomly allocated to either non-invasive management of caries, or continue with usual care. Patients were followed for three years and caries incidence assessed. A patient-level decision analytic model was constructed to assess the cost-effectiveness of the intervention at two years, three years, and hypothetical lifetime.
Results:
Twenty-two dental practices and 920 patients were recruited. Within the clinical trial there was a significant difference in caries increment favouring non-invasive therapy at both two and three years. Efficacy was independent of age, gender, medical concerns, fluoride history, or previous history of dental caries, in a population of patients attending for treatment in private dental practices, in a variety of locations both urban and rural. Cost per DMFT avoided estimate was A$1287.07 (two years), A$1148.91 (three years) decreasing to A$702.52 in (medium) and A$545.93 (high) risk patients (three years).
Conclusions:
A joint preventive and non-invasive therapeutic approach appears to be cost-effective in patients at medium and high risk of developing dental caries when compared to the standard care provided by private dental practice.
