The study also aimed to provide a more objective definition of the term ‘uncomplicated’ root canal treatment as described by the Association for Dental Education in Europe (ADEE) and the European Society of Endodontology (ESE) undergraduate curriculum guidelines for Endodontology. Methodology: The development process involved a narrative review of the literature to identify the complexity factors associated with root canal treatment on permanent teeth; an iterative development and analysis process to assess the weighting of these factors; and the programming of digital software to enhance the efficiency and user interface of the assessment form. Validation of the tool was sought with a panel of 35 specialist endodontists to assess clinical scenarios and assess the consensus inter-examiner agreement with the outcomes provided by the E-CAT. The inter-user and intra-user reliability studies were conducted with 15 dentists to evaluate the same clinical cases and by repeating the experiment 9 months later. The ease of use of the form was also assessed. Results: The E-CAT was successfully developed with a total of 19 complexity criteria and hosted on a secure server under the domain of www.e-cat.uk. The tool provides a smart interactive filtering mechanism and automatic background calculation of the risk scores. Three levels of complexity were defined: class I (uncomplicated), class II (moderately complicated) and class III (highly complicated). The consensus of the panel of endodontists had excellent agreement with the outcome of the E-CAT. The inter-user and intra-user reliability was found to be 0.80 and 0.90, respectively. The average time to assess a case was 1:36 min. Conclusion: The E-CAT gave promising results providing an efficient and reliable platform to assess the complexity of cases undergoing root canal treatments. The study design allowed the formulation of a more objective definition to describe ‘uncomplicated’ root canal treatment as referred to by the ESE and ADEE guidelines. This study is advantageous for educational, public health and referral pathways.
