- Brief Summary
Microsurgical tunneling flap procedures using connective tissue grafts (CTG) are predictable for treating teeth with gingival recessions. Cross-linked hyaluronic acid can be used in conjunction with subepithelial palatal connective tissue grafts to improve postsurgical results. The aim of this study is to evaluate clinically the use of tunnel technique with CTG and cross-linked hyaluronic acid in addition to CTG alone for the treatment of multiple gingival recessions.
- Detailed Description
The treatment of multiple adjacent recession appears to be challenging for the clinician due to large surgical field, variation in teeth position in the dental arch (prominent roots), variation in recession size, thin phenotype and insufficient keratinized tissue in many teeth. Surgical treatment of all multiple recession in one dental arch during one session appears to be optimum. Surgical treatment time is longer, however patient doesn't need to undergo multiple surgeries, pharmacological therapies and postsurgical instructions. Esthetic concern seems to be one of the most common complaints from patients. Among utilized surgical techniques tunneling flap procedures using connective tissue grafts (CTG) with or without biologics such as an enamel matrix derivative (EMD) or hyaluronic acid (HA) provided the most successful outcomes for the treatment. Cross-linked hyaluronic acid can be used in conjunction with subepithelial palatal connective tissue grafts to improve postsurgical results and improving healing process. The aim of this study is to evaluate clinically the use of tunnel technique with CTG and cross-linked hyaluronic acid in addition to CTG alone for the treatment of multiple gingival recessions.

Group Intervention Description Modified Coronally Advanced Tunnel With Connective Tissue Graft The tunnel technique for root coverage with CTG without Cross-linked Hyaluronic Acid Procedure: A modified microsurgical tunnel technique by Zuhr et al. (2007). Initial sulcular incisions with a microsurgical blade are followed by a split-thickness buccal flap preparations using the tunneling knives. The preparation is extended into the mucosal tissue to gain sufficient flap mobility. The papillary regions are detached in their buccal aspects with the periosteum. The graft is inserted into the tunnel and stabilized with absorbable suspensory sutures. The buccal flap is advanced coronally and stabilized with non-absorbable suspensory sutures.

- Primary Outcome Measures
Name Time Method Periodontal parameters measured before surgery. 1-7 days before surgery 1. Probing pocket depth (PPD) MEASURED IN MILIMETERS: distance from the gingival margin to the bottom of the gingival sulcus
2. Clinical attachment level (CAL) MEASURED IN MILIMETERS: distance from the cementoenamel junction to the bottom of the gingival sulcus
3. Recession height (RH) MEASURED IN MILIMETERS: distance from the cementoenamel junction to the gingival margin
4. Width of keratinized tissue (WKT) MEASURED IN MILIMETERS: distance between the most apical point of the gingival margin and the mucogingival junction
5. Gingival thickness (GT) MEASURED IN MILIMETERS: thickness of the gingiva measured 2-3 mm apical to the gingival margin
- Secondary Outcome Measures
Name Time Method Periodontal parameters measured after surgery. 12 months after surgery 1. Probing pocket depth (PPD): distance from the gingival margin to the bottom of the gingival sulcus
2. Clinical attachment level (CAL): distance from the cementoenamel junction to the bottom of the gingival sulcus
3. Recession height (RH): distance from the cementoenamel junction to the gingival margin
4. Width of keratinized tissue (WKT): distance between the most apical point of the gingival margin and the mucogingival junction
5. Gingival thickness (GT): thickness of the gingiva measured 2-3 mm apical to the gingival margin
ALL ABOVE PARAMETERS ARE MEASURED IN MILIMETERS
