This case report presents a complicated type 3a DI in a maxillary lateral incisor with labial talon cusp and root bifurcation. Although lingual talon cusp is common in maxillary lateral incisor, labial talon cusp is rare. An auxiliary palatal root in maxillary lateral incisor is also unusual. No such case involving all three variations has been described in the literature. The DI was classified as type B4 according to Schulze and Brand, as it involved division of pulp and root. DI was managed by orthograde MTA, radisectomy and periodontal regeneration was done for the palatal root. Labial talon associated with DI and can lead to early periodontal\/pulpal involvement. Type 3 DI can affect the root with marked dilatation and division. Additional palatal root should be carefully detected in type 3a DI and managed with the aid of CBCT.<\/jats:p>","DOI":"10.1111\/aej.12635","type":"journal-article","created":{"date-parts":[[2022,5,30]],"date-time":"2022-05-30T13:00:05Z","timestamp":1653915605000},"page":"192-201","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Rare
