Palato gingival groove: unique anomaly in maxillary anterior region

Dental Anomalies are most commonly observed in maxillary anterior region. Palatogingival groove is one of them seen with maxillary lateral incisor either unilaterally or bilaterally. It is an artifice for plaque accumulation which leads to osseous defect. Diagnosis – proper diagnosis is base for treatment plan, which is made on the basis of clinical examination, along with radiographic examination as well as CBCT scan. Treatment –treatment is based on (i) complete eradication of microbials, (ii) permanent and thorough sealing of the root groove that communicates between the root canal and the periodontium, and (iii) periodontal regeneration and complete healing of the periodontium. In 2003, Kerezoudis et al. summarized the treatment interventions needed in cases of relatively shallow PGG: (i) Surgical removal of granulation tissue and irritants, (ii) A gingivectomy and apically positioned flap, (iii) Surgical exposure and flattening of the groove by grinding, with or without application of guided tissue regeneration techniques, (iv) Positioning a restoration in the groove and (v) Orthodontic extrusion of the tooth.
