curved canal, distolingual root, endodontic mishap, prognosis, treatment protocolAbstract
Radix entomolaris (RE) is an anatomical variant of the permanent mandibular molar (MM) with various complex anatomy. However, there is limited literature on the guideline on endodontic management of RE, resulting in unclear understanding on the endodontic treatment outcomes. Hence, this study aimed to map current case reports on endodontic treatment modalities, occurrence of endodontic mishaps, and outcome of MM associated with RE. A systematic search was performed in PubMed, Google Scholar, Scopus, Science Direct, PLOS, and Lilac databases for English articles published between 2000 and 2022 that met the inclusion criteria. The search yielded 1435 results; after screening was completed, only 58 articles were included in the study and critically appraised using JBI critical appraisal tool. Amongst the modifications made in endodontic management of RE were utilising angulated periapical radiograph supplemented with cone-beam computed tomography, extending the access cavity distolingually, and maintaining a small apical size of #25. There were 12% incidence of endodontic mishaps (separated instrument, ledge, missed canal, and extruded sealer) on RE. The success and survival rate of MM associated with RE were 58.7% and 40% respectively, at an average of 8.4 months. The basic management of MM with RE is similar to that of other MM. However, emphasis should be made on RE identification to prevent endodontic mishaps that can influence the endodontic treatment outcome.
