Abstract

Introduction:

This article reports 3 representative cases of interdisciplinary management of a palatogingival groove in maxillary lateral incisors. The development, pathology, and effectiveness of management approaches in cases involving a combined periodontal-endodontic lesion with a palatogingival groove are discussed.

Methods:

We describe 3 patients with a noncontributory medical history presenting with a chief complaint related to a maxillary incisor and diagnosed with a combined periodontal-endodontic lesion with a palatogingival groove at Seoul National University Dental Hospital, Seoul, Korea.

Results:

Palatogingival grooves were mostly associated with deep periodontal pockets connected to a periapical lesion. Optional collaborative treatments were performed according to the condition as follows: case 1, root canal treatment (RCT), open flap debridement, odontoplasty, and guided tissue regeneration; case 2, RCT, apicoectomy, open flap debridement, and odontoplasty; and case 3, RCT, crown restoration, root planning, and odontoplasty. After clinical examination and radiographic assessments, the periapical lesion and periodontal deep pocket were successfully resolved with periodontal-endodontic collaborative treatment involving both periodontal surgical procedures (cases 1 and 2) and a nonsurgical procedure (case 3).

Conclusions:

Within the limitations of this study, these case reports show that accurate diagnosis of developmental anomalies and elimination of inflammatory irritants are key factors for favorable long-term outcomes.
