Radiographic Assessment of the Healing Pattern Associated With Periradicular Endodontic Microsurgery
A study testing Piezo endodontic surgery and Conventional endodontic surgery in people with Periapical; Infection, run by King Abdullah University Hospital at 2 sites in Jordan.
Trial summary
Endodontic periradicular microsurgery is a dental procedure to treat apical periodontitis in cases in which healing has not occurred after non-surgical treatment or if it is not feasible. Recent advances in techniques and materials have resulted in more predictable outcomes. Read more about this study

About this study
Official title: A 2D and 3D Radiographic Assessment of the Healing Pattern Associated With Conventional and Piezoelectric Periradicular Endodontic Microsurgery
Endodontic periradicular microsurgery is a dental procedure to treat apical periodontitis in cases in which healing has not occurred after non-surgical treatment or if it is not feasible. Recent advances in techniques and materials have resulted in more predictable outcomes. Piezotome is a new and innovative device, but limited evidence is available regarding its use in endodontics. The aim of this study is to assess the healing pattern of conventional periradicular microsurgery and piezoelectric periradicular microsurgery in 2- Dimensional and 3-Dimensional imaging, and further to perform histological analysis for the presence, location, and arrangement of bacteria in the excised apical portion of the root canal system.
Read the detailed description
After meeting the inclusion criteria, a total of 44 Patients in need of endodontic microsurgery with persistent symptoms after acceptable primary root canal treatment or failed retreatment with persistent symptoms/periapical lesions will be included in this study. Participants will be randomly allocated to group one; conventional periradicular surgery or group two; piezoelectric periradicular microsurgery. A preoperative digital periapical and limited view cone beam computed tomography (CBCT) radiographs will be taken for each patient. At 12-18 months recall visit a second digital periapical radiograph and limited view CBCT will be taken. All images will be evaluated on high-definition LCD display with installed ImageJ software and CBCT software, and window settings will be fixed for all cases. Radiographs will be evaluated by two calibrated dentists. The excised root tip with their surrounding tissues will be fixed immediately after harvesting for 24 hours at 4 °C by immersion in 1% glutaraldehyde and 1% formaldehyde and referred to histopathologic laboratory. Fixed specimens will be demineralized in 10% formic acid and processed. Serial sectioning with hematoxylin and eosin staining will be done to locate the areas with the most severe reactions. In addition, the Taylor modification of the Brown-Brenn staining will be used to detect the presence of bacteria.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Piezo endodontic surgeryProcedure or surgery
Osteotomy will be done with Piezosurgery touch. After the soft tissue curettage and uncovering the root apex, the last 3 mm of the root apex will be resected perpendicular to the long axis of the tooth using piezotome. apical preparation will be performed and Biodentine®retrograde filling material will be placed. The flap will be re-approximated and interrupted suture using non-absorbable monofilament suture will be applied. Finally, Post-operative parallel Digital view.
Conventional endodontic surgeryProcedure or surgery
After the soft tissue curettage and exposure of the root apex, the osteotomy will be performed using a conventional surgical handpiece. The same steps will be followed to prepare and restore the root, as well as to reposition the flap.

| Conventional endodontic surgery | Experimental | Experimental: Conventional endodontic surgery The osteotomy will be applied under magnification with a surgical operating microscope at the apical third of the root.
