Objectives: Until today there is no definite treatment protocol for the highly prevalent apical periodontitis (AP) and concerns have been raised that some teeth which could be retained with root canal treatment (RCT) are replaced with implant-supported crowns (ISC). This study evaluated German dentists’ preferences for the treatment of AP regarding the selection between tooth retention using initial/repeated RCT compared to extraction followed by replacement with ISC, fixed or removable dental prostheses or no replacement.
Methods: Using an online-survey German dentists (n=260, 11,45% responds rate) rated different treatment options for four case scenarios with AP: an anterior/posterior tooth without/with previous RCT. Statistical analysis included rmANOVA for intra-case comparison and Chi2 test for independence for associations (p ≤ .05).
Results: Tooth retention using initial/repeated RCT was ranked first of all four case scenarios with 99,6-98,9% of the participants rating this option as (very) appropriate for the treatment of AP. ISC after tooth extraction was second-ranked with 70,7-56,6% (very) appropriate ratings. Results show a higher preference for ISC on posterior teeth or teeth with previous RCT. Mean rating levels of the different treatment options show a significant difference for all four case scenarios (p < .001). The preference for retention of posterior teeth using RCT is associated with the work experience of the dentists (p ≤ .05). Preference for retention of teeth with previous RCT is associated with the percentage of privately-insured patients in the dentist’s practice (p < .001).
Conclusions: The majority of German dentists prefer tooth retention using initial/repeated RCT for the treatment of AP. The presented results reflect a lack of consensus regarding the indication of different treatment options for AP among the respondents.
