Objectives To identify behavioral, preferential, and professional factors influencing the use of amalgam in private practices; and to compare the incidence of the placement of amalgam versus composite resin restorations in the province of Ontario and its pedagogical implications on dental curricula. Methods Participants responded anonymously to a 23‐question online survey about their current use of dental amalgam and composite resins as well as their opinions regarding both dental materials. The explanatory variables were associated bivariately with the outcome variables, and the most significant predictors were identified using the multivariate analysis. Results Higher percentages of amalgam use were reported among clinicians who trained in Canada only ( P = .009), who graduated before 1980 ( p = <.001) and who work outside private practice ( p = <.001). Familiarity with amalgam was higher among clinicians who are female ( p = <.001), older ( p = <.001), trained only in Canada ( p = .017), who graduated prior to 2000 ( p = <.001), and who work in locations with populations over 100,000 ( p = .042). Familiarity with composite resin was higher among clinicians who graduated more recently ( p = .002). A higher percentage of females ( p = <.001), younger clinicians ( p = <.001), recent graduates ( p = <.001), and clinicians who work in private practice ( p = .043) suggested that over 50% of dental student training time be allocated to amalgam. Conclusions Decreased amalgam use was reported by later dental graduates and private practitioners; this may be impacted by familiarity with dental amalgam. As amalgam remains a safe and effective dental material, its removal may not be prudent. Dental educators play a crucial role in the future of amalgam opinion and use.
