A survey of general dentists on the involvement of endodontists in restorative procedures.

Abstract

Background: The authors investigated, via a web-based survey, the perceptions of general dentists in the United States regarding endodontists restoring endodontically treated teeth (ETT).

Methods: A 15-question survey was distributed to American Dental Association members. Participants were asked to rate their comfort with various scenarios. In the control scenario, an endodontist placed restorations without prior discussion with the general dentist. In the experimental scenario, an endodontist trained in endorestorative procedures, having previously discussed their intentions, placed the restorations. Data were analyzed using descriptive statistics, Fisher exact test, McNemar test, and false discovery rate adjustment (P_adj).

Results: The response rate was 48% (N = 544). General dentists were significantly more likely to accept the experimental scenario than the control scenario for post space creation (88.1% vs 84.2%; P_adj = .026), post placement (66.7% vs 52.2%; P_adj = 3.35e-13), and core placement (68.2% vs 55.1%; P_adj = 2.28e-12). Overall, 69% (374) supported endodontists placing restorations after discussion with referring general dentists, 12.9% (70) disagreed, and 18.4% (100) were undecided. Opponents (67) cited lack of trust (64%) and billing preferences (18%). Undecided general dentists (83) identified residency training (28%), case portfolios (16%), and individualized discussions (13%) as factors likely to increase acceptance. More recent graduates, female practitioners, those practicing at community clinics, in rural or urban areas, and in the South or West were significantly more comfortable with endodontists placing restorations (P_adj < .05).

Conclusions: General dentists broadly supported endodontists restoring ETT if they were trained in endorestorative procedures and after prior discussion.

Practical implications: Endodontists should communicate their intent to restore ETT with general dentists to facilitate interdisciplinary collaboration.
