Endo-Perio Lesions and Dentists’ Treatment Approach: A Survey

Abstract Background: Endo-perio lesions have been a great challenge for dentists. The aim of this study was to evaluate the treatment approach of dental practitioners to endo-perio lesions by considering the current endo-perio classification. Methods: An online survey consisting of questions about the treatment approach to three simulated cases with endo-perio lesions by a periapical radiography and questions derived from these cases were prepared. Questions about the patient's age, presence of systemic disease, smoking, and how the single or multi-rooted tooth would affect the treatment plan were also included in the survey. The survey was sent to 1500 dentists via e-mail, WhatsApp and social media. Chi-square test was used for comparison of data. Significance was evaluated at p<0.05. Results: In total, 338 dentists participated the survey and 53% of the participants stated that they perform root canal treatment and initial periodontal treatment simultaneously, when both treatments are required. In Grade 3 case, general dentists, endodontists, and periodontists mostly stated that they would prescribe systemic antibiotics if there was a diffuse extraoral swelling (p<0.05). Moreover, in Grade 3 case, more general dentists chose the option “extraction” as the best choice than endodontists and periodontists (p<0.05). Conclusions: According to the results of this study, general dentists, endodontists, periodontists generally follow different approaches to endo-perio lesions.
