Coronally Advanced Flap with and without Connective Tissue Graft for Treatment of Miller’s Class I and II Gingival Recession: A Comparative Study

Background and objectives: Gingival recession is apically located marginal tissue to the cemento-enamel junction. This problem could be linked to mechanical cause like brushing teeth, or it could be related to periodontal disease. Root covering is indicated for a number of reasons, including aesthetic purpose, root sensitivity, managing or preventing root caries, cervical abrasion, and improving restorative results. The purpose of this study was to examine the results gained from the surgical treatment of localized gingival recessions utilizing coronally advanced flap surgery with and without connective tissue graft. Methods: This study is a clinical cross over study and consists of thirty volunteers with Miller classification, class I and II gingival recession, who visited Duhok Dental Training Center in Duhok city. it starts from December 2022 to May 2024. A comparison study of two procedures was conducted to examine the reduction in gingival recession. 30 patients with gingival recessions had surgery: 15 in the first group (Coronally advanced flap) and 15 in the second group (coronally advanced flap combined with connective tissue graft). Results: According to the investigation there was significant reduction for both techniques (coronally advanced flap and connective tissue graft) for gingival Class I and II recession treatment (-1.53, -2.7) respectively at (P < 0.001). Conclusion: Both surgeries lead to significant reduction of gingival Class I and II recession, provide better root coverage and better esthetic outcomes.
