Abstract:

Objectives: To investigate the association between dentists’ geographic density, perceptions of competition, and various non-clinical factors, with clinical decision-making

Methods: This was a cross-sectional, self-administered survey among a random sample of general dentists in Ontario, Canada (n=3,201). The 46-item survey collected demographic, professional, and practice information, and self-perceptions of competition and financial pressures. Competition was quantified using dentist density, defined as the number of dental clinics lying within a one-kilometer radius around a respondents’ clinic address. The outcome (clinical decision-making, or treatment-intensity), was measured using a set of clinical scenarios, which categorized dentists as either aggressive or conservative. Associations were assessed using bivariate analysis and logistic and linear regressions.

Results: One thousand and seventy-five dentists responded (33.6% response rate). Age (p=0.001), place of initial dental training (p<0.001), number of dependents (p=0.001), number of hours worked/week (p=0.043), billings/hour needed to be profitable (p<0.001), number of hygienists employed (p=0.001), perceptions of practice loans (p=0.02), satisfaction with practice busyness (p=0.084), and feeling competitive pressure from other dentists (p=0.037) were associated with treatment-intensity. Dentists who were <40-years old (OR=2.06, 95% CI:1.39-3.06), American-trained (OR=2.48, 95% CI:1.51-4.06), had student loans (OR=3.96,95% CI:1.88-8.33), large practice loans (OR=1.57, 95% CI:1.02-2.42), perceived other dentists as competitors (OR=1.77, 95% CI:1.01-3.10), and perceived large competitive pressure from other dentists (OR=1.63, 95% CI:1.07-2.49), were more likely to be aggressive in their treatment choices. Interestingly, dentists located in low dentist density areas (OR=1.31, 95% CI:1.03-1.68) were also more like to be aggressive.

Conclusions: This study is the first to explore the impact of competition and other non-clinical factors on the clinical decision-making of dentists in a Canadian context and will serve as a foundation for future research in this area.
