Background: In the past decade, gingival tissue has been regenerated using subepithelial connective tissue grafts (SECT). This report presents the use of frozen subepithelial connective tissue (FSECT) for increasing the zone of attached keratinized gingiva (KG).
Methods: Five cases, 4 females and 1 male, aged 55 to 73 years, presented with inadequate attached KG. The SECT grafts were harvested from the palatal flap during conventional flap surgery. All grafts were frozen immediately. Five weeks to 10 months later, the grafts were placed in areas in which patients had inadequate KG.
Results: In all cases, healing was uneventful. All cases were followed up 3 months to 1.5 years. An increase of 1 to 3 mm of KG was achieved.
Conclusions: These cases show that the FSECT graft is useful in treating mucogingival problems. Further randomized controlled trials over long periods of time are necessary to establish whether this procedure offers long-term benefits to patients.

Department of Periodontics, Thai Moogambigai Dental College and Hospital, Chennai, Tamil Nadu, India.
Objectives: Comparative assessment of the effectiveness of coronally advanced flap (CAF) with subepithelial connective tissue graft (SCTG) and the envelope technique with SCTG in Miller's Class I recession utilizing soft tissue-cone-beam computed tomography (ST-CBCT) and root coverage esthetic score (RES).
Materials And Methods: Twenty patients were randomly assigned to Group I (CAF + SCTG) and Group II (envelope technique + SCTG) using the coin toss method, with 10 patients in each group. Recession height (RH) and width (RW), probing pocket depth (PD), clinical attachment level (CAL), and keratinized tissue height (HKT) were assessed at baseline and 6 months.

This study aimed to investigate factors that influence the 12-month outcomes after the treatment of multiple gingival recessions (GRs) with a modified coronally advanced tunnel (MCAT) and a subepithelial connective tissue graft (SCTG), with cross-linked hyaluronic acid (HA, tests) or without (controls). : Twenty-four patients with 266 GRs were treated. A logistic regression model was set to identify the baseline parameters that could predict the 12-month outcomes.
