Oehlers' Type III DI is the most serious form, in which the inherently invaginated channels communicate with periodontal and dental pulp tissue, increasing the risk of bacterial contamination. However, varying and complex anatomical features make diagnosis and treatment challenging. Conventional endodontic therapies promote healing by avoiding unnecessary interventions (e.g., surgical or other invasive treatments). Radiographic examination can reveal the structural details of such malformations. We obtained multiple procedural details for treating Type III DI based on radiographic analyses from our clinical experience. In addition, we introduce a new classification strategy for the management of Type III DI that is more applicable to treatment needs. This study aimed to discuss the anatomical features and current treatment considerations of Type III DI.<\/jats:p>","DOI":"10.1111\/aej.12847","type":"journal-article","created":{"date-parts":[[2024,4,23]],"date-time":"2024-04-23T10:29:33Z","timestamp":1713868173000},"page":"377-387","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Endodontic management considerations for Type <scp>III<\/scp> dens invaginatus based on anatomical characteristics: A case series"],"prefix":"10.1111","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5777-9452","authenticated-orcid":false,"given":"Jia","family":"Wang","sequence":"first","affiliation":[{"name":"1.
