Microbial Evaluation and Knot Safety of Different Suture Materials in Patients Undergoing Endodontic Microsurgery-A Randomized Controlled Trial.

Once the patient is selected according to the mentioned criteria , patients will be anesthetized, a full thickness flap will be reflected followed by osteotomy. Periapical endodontic surgery will be performed with the aid of an operating microscope followed by flap approximation and suturing of the surgical site. Suture removal will be carried out 3-5 days. On the day of suture removal, all sutures will be assessed under a surgical microscope and a digital camera. Each suture will then be cut and collected using separate sterile forceps and scissors and transferred to the lab and prepared for microbial analysis.
