Xenogenic Collagen Matrix and Subepithelial Connective Tissue Graft in the Treatment of Gingival Recession

Gingival Recession Localized Moderate Clinical Trial

Official title: Clinical Comparison of Coronally-advanced Flap Plus Xenogeneic Collagen Matrix (Fibro-Gide®) and Subepithelial Connective Tissue Graft in the Treatment of Gingival Recessions

Status Completed

Clinical Trial Summary

this study is a Clinical evaluation of using Xenogenic collagen matrix (XCM) plus coronally advanced flap (CAF) compared to subepithelial connective tissue graft (SCTG) plus coronally advanced flap to treat Miller class I gingival recession. A split-full-split thickness flap will be elevated in the (XCM+CAF) group while it will be an only partial thickness flap in the (SCTG+CAF) group. The sample size will be 15 patients. Each patient has bilateral Miller Class I gingival recessions; and as a split-mouth study design one side will be treated with (SCTG+CAF), while the other will be treated with (XCM+CAF).

Clinical Trial Description

The aim of this study is to clinically compare between the subepithelial connective tissue graft (SCTG) plus coronally advanced flap (CAF) which is defined as the golden standard for the treatment of gingival recessions and Xenogenic collagen matrix (XCM) plus coronally advanced flap (CAF) to treat class I Miller gingival recession. CAF elevation will be done as it described by (De Sanctis & Zucchelli 2007) with modifications in the the control group.The flap will be partially elevated in the (SCTG+CAF) group while it will be a split-full-split thickness flap in the (XCM+CAF) group, and finally the flap will stabilized coronally. Fifteen patients who have bilateral buccal Miller Class I gingival recession defects will be enrolled in this study. These defects will be distributed randomly into two groups: the test group (XCM+CAF) and control group (SCTG+CAF). Clinical parameters will be evaluated: Recession depth (REC), change in visible plaque index, recession width (RW), width of keratinized tissue (KT), thickness of gingival tissue (GT), probing depth (PD), clinical attachment level (CAL), healing index (HI), questionnaires will be given to evaluate each of patient perceptions, pain index (PI), and changes in root sensitivity by using visual analog scale (VAS). ;
