Diagnosis consensus among endodontic specialists and general practitioners: An international survey and a proposed modification to the current diagnostic terminology

Abstract

Introduction: This survey aimed to determine the consensus amongst endodontic specialists in North America and practitioners worldwide to diagnose the pulp and periapical conditions of selected case scenarios encountered in daily practice using the American Association of Endodontists (AAE) pulpal and periapical diagnostic terms. Secondly, an attempt was made to suggest modifications in terms accordingly. Methodology: A survey designed by two endodontic educators was sent to endodontists in North America and clinicians worldwide through an electronic database. The survey included socio-demographic questions followed by the clinical and radiographic presentations of four clinical scenarios. The participants were then requested to provide the pulpal and the periapical diagnosis of 11 teeth presented in these cases (22 answers in total/participant) using the AAE diagnostic terminology. Cases were designed to include 12 pulpal/periapical conditions as control (non-controversial conditions) and ten so-called controversial conditions. A proportion threshold of 10% was required for any diagnostic term to be reported in this survey. The participants were divided into two groups based on the region of endodontic training and/or practice to ‘Specialised North American’ or ‘International Practitioners,’ and their results were statistically compared using chi-squared tests (p
