About
The aim of this randomized-controlled clinical trial is to compare the patient morbidity and root coverage outcomes of a sub-epithelial connective tissue (SeCTG) used in combination with a coronally advanced flap (CAF) and tunnel technique (TT).
The primary objective of the study is to demonstrate the superiority in terms of the post-operative course and pain of the CAF+SeCTG when compared to the TT.
Full description
The aim of this randomized-controlled clinical trial is to compare the patient morbidity and root coverage outcomes of a sub-epithelial connective tissue (SeCTG) used in combination with a coronally advanced flap (CAF) and tunnel technique (TT).
The study will be designed as a single-centre, randomized, clinical trial on the treatment of single gingival recessions. The study assessed two different treatment modalities: the tunnel technique with subepithelial connective tissue graft (TT), compared to the coronally advanced flap with subepithelial connective tissue graft (CAF+SeCTG) in terms of clinical outcomes, and post operative morbidity.
50 patients with one gingival recession each will be treated. Evaluation of patient morbidity will be performed 3 days and 1 week after the surgery. Clinical outcomes will be evaluated 12 months post operatively. Clinical outcomes included percentage of root coverage (RC) and complete root coverage (CRC) will be recorded. Patient morbidity will be evaluated with questionnaires.
Clinical measurements (1 week before surgery and at the 12 months follow-up)
Patient morbidity
Kolmogorov-Smirnov test will be used to analyze distribution of continuous variables. Continuous variables are expressed as means ± standard deviation (SD) and compared at baseline by the U Mann-Whitney test. This test will be also used to compare mean changes post vs. baseline measurements. The Wilcoxon test will be used to compare post vs. baseline measurements. Spearman correlation will be used to evaluate associations.
Level of significance was set at 0.05. The SPSS v. 20 software (SPSS Inc., Chicago, IL, USA) will be used for all analyses.
