This survey aimed to determine the consensus among endodontic specialists and practitioners worldwide on the diagnosis of selected case scenarios, and to suggest modifications to the current diagnostic terms. The survey found a lack of consensus among clinicians, regardless of their training and region of practice, on the appropriate diagnostic terms for specific clinical conditions.
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 < .05). Results The survey included 421 participants. 74% were endodontists, and 46.1% were amongst the 'Specialised North American' group and 53.9% amongst the 'International Practitioners'. Eleven of 12 control conditions had an almost complete agreement amongst the participants regarding the diagnostic terms selected, ranging between 82% and 96%, with no other diagnostic term exceeding the 10% threshold. All the controversial conditions yielded more than one diagnostic term selected/condition that exceeded the 10% threshold for groups ('Specialised North American' and 'International practitioners'). There were no differences in the diagnostic terms selected between the two groups; however, the weight for each term varied between the groups in some cases. Conclusion There is a lack of consensus amongst clinicians, regardless of their training and region of practice, on the appropriate diagnostic terms to be used in particular clinical conditions. More diagnostic terms and modifications in the current terms may be required to establish a more reliable diagnostic terminology.
