Figure 2.

Preferences of the participating dental clinicians regarding treatment decisions for each multirooted tooth in the first and second case modules. The upper two circle graphs in each panel present the proportion of preferences for periodontal therapy (to save the tooth) or placement of a dental implant (after removing the tooth), immediately before and after the debates. The lower graphs show subcategorized results from the periodontal and implant conferences. A tendency was noted among the participants in the periodontal conference to prefer periodontal therapy over dental implants. The preference for periodontal therapy increased after the debates and was also greater in the second case than in the first case.
