Methods A mail-out survey (census of Ontario endodontists, periodontists, prosthodontists, and oral and maxillofacial surgeons; n = 498, 40% response rate) and a Web-based survey (sample of Ontario general dentists; n = 1983, 15% response rate) were conducted. Participants ranked their treatment preferences for 4 clinical scenarios: an anterior or posterior tooth, without or with previous RCT. Associations between treatment preferences and covariates were explored by using bivariate and logistic regression analyses (P ≤ .05). Results For all 4 scenarios, the majority of participants preferred either RCT or ISC, whereas other treatment options were preferred by ≤3.1% of the participants in any professional registration category. A pattern of declining preference for RCT and increasing preference for ISC was noted across the scenarios, with significantly lower preference for RCT and higher preference for ISC associated with teeth needing repeated RCT compared with initial RCT (odds ratio [OR] = 3.3; confidence interval [CI], 2.5– 4.4). Preferences were significantly lower for RCT and higher for ISC among general dentists (OR = 6.4; CI, 2.3–17.6), prosthodontists (OR = 9.1; CI, 3.0–28.3), periodontists (OR = 18.3; CI, 6.4–51.6), and surgeons (OR = 30.1; CI, 10.8–86.6) when compared with endodontists. Conclusions More surveyed dentists preferred RCT than ISC for teeth with apical periodontitis requiring initial RCT than repeated RCT. The dentists' preferences were associated with their professional registration but not with other characteristics.
