Treatment of the Palato‐Gingival Groove With Guided Tissue Regeneration. Report of 10 Cases

Abstract

The purpose of this study is to demonstrate the potential of using a barrier in the treatment of palato-gingival groove defects. The study group consisted of 10 patients. Prior to treatment, the palato-gingival groove on maxillary lateral incisors was measured with calibrated periodontal probe from the cemento-enamel junction (CEJ) to the free gingival margin (FGM) and from the FGM to the base of the pocket (BP). Probing depth (PD) was calculated and bleeding on probing indicated. Surgical procedures consisted of flap reflection, removal of granulation tissue, and scaling and root planning of the groove. An expanded polytetrafluoroethylene membrane was sutured over the palato-gingival groove. Six months postsurgery, all measurements were repeated. Statistical analysis compared results using means, standard deviations, and paired t tests. Results showed an improvement in clinical attachment gain, probing depth reduction, and decreased bleeding on probing. This study demonstrates the potential of guided tissue regeneration in the treatment of palato-gingival groove defects. A random blinded clinical trial is necessary, however, to fully assess the potential of this procedure in treatment of palato-gingival groove defects.

Recognition and management of palatogingival groove for tooth survival: a literature review

“…35 Anderegg et al also reported 10 cases of successful treatment after 6 month follow-up using a polytetrafluoroethylene membrane 57…”

Conservative management of a periradicular lesion associated with a palatogingival groove

“…Similarly, Rethman [16] performed periodontal surgery, odontoplasty, citric acid application, and Emdogain therapy. Anderegg and Metzler [17] performed removal of granulation tissue, and scaling and root planning of the groove.…”

“…Case reports have described several treatment modalities to eliminate PGGs, such as odontoplasty, resection of accessory roots, intentional replantation, periodontal regeneration, and extraction. [14][15][16][17][18] Other studies used restorative materials, such as amalgam, glass ionomer cement, and composites, to fill the PGG. [12,19,20] The treatment options vary according to the presence and the depth of the pulp cavity.…”

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

“…Fortunately, newer treatment options are available that provide better potential for retaining these teeth. Although the treatment of teeth with palatal grooves has not been evaluated in a controlled investigation, multiple case reports describe treatment modalities ranging from resection of an accessory root to intentional replantation and periodontal regeneration with various materials depending on the extent of the osseous defect (13)(14)(15)(16)(17)(18). Other authors have reported using restorative materials to eliminate palatal grooves at the coronal aspect (19).…”
