Comparative evaluation of the laterally closed tunnel technique with connective tissue graft and collagen matrix for treating localized type 1 gingival recession: a randomized, controlled clinical trial.

ABSTRACT:

Objective

There is limited evidence about the short- and long-term outcomes of the laterally closed tunnel (LCT) technique for gingival recession (GR) treatment. This clinical trial aimed to evaluate the short-term clinical effectiveness of and patient-reported outcomes of the LCT technique when used in combination with either connective tissue graft (CTG) or collagen matrix (CM).

Materials and methods

A total of forty patients were randomly assigned to either the control group (LCT + CTG) or the test group (LCT + CM) for localized GR type 1 treatment. Primary outcome measures included recession depth (RD), recession width (RW), root coverage percentages (MRC%), and complete root coverage percentage (CRC%). Secondary outcomes included gingival thickness (GT), keratinized tis
