Clinical Evaluation of Sutures in Periodontal Surgery

Clinical Evaluation of Four Types of Suture in Periodontal Surgery

The aims of this study were to evaluate and compare tissue erythema, edema and knot loosening among four types of suture one week after periodontal surgery.

Forty patients participated in this prospective, randomized, double-blind clinical trial. Vertical mattress sutures were used following resective periodontal surgery performed by one operator. Four suture materials were selected for evaluation: 5-0 silk; 5-0 polypropylene; 5-0 polyglycolic acid (PGA), and 4-0 polytetrafluoroethylene (PTFE). Seven days after the surgical procedure, the surgeon assessed suture loosening and removed the sutures. A blind researcher clinically evaluated erythema and edema.

Inclusion Criteria:

• Qualification for the study was based on the need for resective periodontal surgery (apically positioned flap and osseous recontouring) at four or more consecutive interproximal sites per quadrant

Exclusion Criteria:

• systemic diseases, such as diabetes, chronic obstructive pulmonary disease, or an immunologic disease that would affect wound healing; allergies to prescribed medication; and/or current pregnancy or breast feeding were excluded from the study
