Comparison of two different sutures on postoperative complications following periapical surgeries: A prospective, randomised controlled trial

Wound closure is a key element for successfulhealing of surgical sites and aids in reducing postoperative complications likepain, swelling, infection, etc. Literature has advocated use of sutures,surgical clamps, and adhesive agents for securing and stabilizing detachedtissues for the subsequent satisfactory healing. Sutures are the most frequently used medical devicefor wound closure. They support tissue during the early phase of healing untilit regains enough tensile strength. Regardless of the suture material origin,its essential role is to support the tissue until continuity of surface andenough tensile strength is regained during the process of wound healing. Good sutures require specific physicalcharacteristics and properties, such as good resistance to traction,dimensional stability, lack of memory, good knot security, and sufficientflexibility to avoid damage to the oral mucosa. At the same time, theymust avoid or limit bacterial adhesion and proliferation to those parts exposedto oral fluids, thereby avoiding contamination inside the wound. A good suturematerial must show a brief exudative phase and must not interfere with cellularproliferation or connective tissue organization. There are many suturingmaterials now available in the market. These materials are classified asbraided multifilament and monofilament or bio absorbable and nonabsorbable. However, the selection of suture material forperiapical surgery is often based on surgeons’ choices rather than scientificdata and has not been extensively investigated. Hence, we propose a randomizedcontrolled trial to compare efficacy of 4-0 prolene (3/8 reverse cutting)versus 4-0  PTFE suture (3/8 reversecutting) in periapical surgeriesin terms of postoperative complications, along with patient as well assurgeon’s satisfaction.
