Comparison between coronally advanced flap technique and modified tunneling technique utilizing perforated acellular dermal matrix in treatment of multiple gingival recessions

Abstract

Objective: The aim of the present study was to evaluate the root coverage outcomes treated by modified tunneling technique (MTT) and compare it to coronally advanced flap (CAF) technique utilizing perforated acellular dermal matrix (PADM). Subjects and Methods: Twenty patients with 40 gingival recession (GR) sites of Miller class I and class II were selected to participate in this study. Sites treated by MTT were assigned as group I while sites treated by CAF were assigned as group II. PADM was incorporated in both groups. Patient satisfaction test, root coverage esthetic score (RES) system and periodontal chart including recession height (RH), recession width (RW), width of keratinized tissue (KW), Thickness of the keratinized tissue (TKT) were used in the clinical evaluation. Results: MTT showed superior results in relation to patient satisfaction test and RES. CAF showed higher root coverage percentage (94±0.0) than MTT (89.5 ±9.30) without statistically significant difference among them. Conclusion: MTT is considered a good treatment modality for GR, it meets patients demands and gives clinical acceptable results.
