Description

To evaluate the association between the width of keratinized tissue and attached gingiva with root coverage outcomes in RT1 gingival recession defects of maxillary and mandibular anterior teeth treated with subepithelial connective tissue graft (CTG) using a minimally invasive technique : modified vestibular incision subperiosteal tunnel access(m-VISTA). OBJECTIVES 1. PRIMARY OBJECTIVES 1. To analyze relation and association at 3 and 6 months outcomes in terms of CRC, mRC and gingival margin position with baseline parameters including width of keratinized tissue and width of attached gingiva, after providing mucogingival plastic surgery in the form of m-VISTA+CTG for the treatment of RT1recession defects. 2. To evaluate 3 and 6 months outcomes (percentage of root coverage, width of keratinized tissue and width of attached gingiva), after providing mucogingival plastic surgery in the form of m-VISTA+CTG for the treatment of RT1recession defects. 3. To access the long-term stability of gingival margin achieved from 3 months to 6 months. 2. SECONDARY OBJECTIVES 1. To access recession depth (RD), recession width (RW), probing pocket depth (PPD), mid buccal clinical attachment loss (bCAL), change in gingival thickness (GT) at baseline, at 3 months and 6 months. 2. To access patient related outcomes measures (PROM) in pain and hypersensitivity in teeth with gingival recession undergoing recession coverage.

Interventions

Vestibular incision subperiosteal tunnel access with connective tissue graft in treating RT 1 gingival recession defects (Procedure)
the aim of this prospective clinical study is to determine if anatomical factors such as keratinized tissue width and attached gingiva width influence recession defects coverage of RT1 recession treated with minimally invasive surgical technique along with connective tissue graft. Keratinized tissue width and attached gingiva width are considered important for maintaining gingival health and long-term stability after root coverage. However, there is limited and unclear evidence on how much keratinized or attached gingiva is actually needed for successful root coverage. Most previous studies have focused on soft tissue thickness rather than these parameters.
