Multidisciplinary considerations for the management of palatogingival grooves on incisor teeth: a literature review

摘要

A palatogingival groove is just one of the many morphological abnormalities that may affect the 'embryologically hazardous' region of the maxillary lateral incisor tooth. Although reports of their prevalence are inconsistent, they are not an uncommon finding in clinical practice. Palatogingival grooves may predispose a tooth to localised periodontal attachment loss and/ or endodontic pathology. Morphological variations associated with the grooves may complicate treatment from a periodontal, endodontic or prosthodontic perspective. Thus, the management of a palatogingival groove may necessitate a multidisciplinary approach. This article will provide an overview of the morphology, development and prevalence of palatogingival grooves, and an update on the diagnosis and numerous therapeutic options available.
