About

The goal of this randomized clinical trial is to determine whether selective curettage combined with cyanoacrylate tissue adhesive improves clinical outcomes in endodontic microsurgery compared with the conventional approach. The study purpose is to evaluate the postoperative healing associated with this conservative surgical protocol.

The main questions it aims to answer are:

Does selective curettage with tissue adhesive reduce postoperative pain, swelling, and complications compared to complete curettage with suturing?

How does selective curettage affect clinical and radiographic healing of persistent periapical lesions?

Researchers compared complete lesion curettage with suturing to selective curettage (40-70% lesion removal) with cyanoacrylate tissue adhesive closure to assess differences in healing and patient-related outcomes.

Participants :

Underwent endodontic microsurgery using one of the two surgical protocols Attended follow-up visits at 1, 3, and 7 days for clinical evaluation of pain, swelling ,Discomfort , Bleeding , Local reaction and Wound Dehiscence

Attended follow-up visits at 3, 6, and 12 months for clinical and radiographic evaluation of periapical healing using 2D radiographs and CBCT

24 participants in 2 patient groups

Complete Periapical Lesion Curettage and Suturing

Active Comparator group

Description:

patients underwent conventional endodontic microsurgery with complete removal of the periapical lesion followed by flap repositioning and closure using sutures.

Treatment:

Procedure: Complete Periapical Lesion Curettage and Suturing

Selective Lesion Curettage and Cyanoacrylate Tissue Adhesive

Experimental group

Description:

Patients underwent endodontic microsurgery with selective removal of approximately 40-70% of the periapical lesion, followed by flap closure using cyanoacrylate tissue adhesive without sutures.
