Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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)

* Gingival recession height (GH)
* Probing depth (PD)
* Clinical attachment level (CAL)
* Height of keratinized tissue (KTH)

Patient morbidity

* Quantity of analgesics taken during the first week post-surgery.
* Patients' post operative discomfort, bleeding, stress and inability to chew was evaluated with a questionnaire given to patients 3 days following surgery.

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.
