Combined Endodontic-Periodontic Treatment of a Palatal Groove: A Case Report

Conservative management of a periradicular lesion associated with a palatogingival groove

“…[30] Case reports have presented maxillary lateral incisors with PGGs that needed endodontic and periodontal management. [12,31] Different treatment approaches has been performed to manage PGG. Wei et al [14] treated the tooth with PGG by conventional endodontic therapy in combination with periodontal treatment including accessory root resection, odontoplasty and bone grafting.…”

A Micro–Computed Tomographic Analysis of Maxillary Lateral Incisors with Radicular Grooves

“…11, a tiny transverse canal was found between the main canal and the invagination. This communication would allow the penetration of irritants and microorganisms from the periodontal pocket into the pulp tissues, and this continuous threat may lead to pulp necrosis; vice versa, a primary endodontic infection may follow the same path and egress toward the invagination, causing a persisting periodontal lesion (4,10). In these situations, combined endodontic-periodontal treatment is required for ensuring better outcomes.…”

“…It is predominantly found on the lingual aspect of maxillary lateral incisors (2,3). This anomaly is also known as the palatal groove, the palatogingival groove, the radicular lingual groove, a developmental radicular anomaly, the cinguloradicular distolingual groove, and the vertical developmental groove in dental literature (4). In anthropology, it is termed as the interruption groove or the coronoradicular groove.…”

The palato-gingival groove - anatomical anomaly occurred in maxillary lateral incisors: case reports

“…Based on the study of Schwartz et al 10) , the apical one-third of each canal was obturated with gutta-percha (Diadent, Burnaby, BC, Canada) and sealer (AH26; Dentsply, Tulsa, OK, USA). In anticipation of the need for significant odontoplasty of the palato-gingival groove, dual-cure composite resin (Luxacore; DMG, Hamburg, Germany) was then placed into middle and cervical thirds of the two canals for the best possible seal of the root canal system.…”
