NCT05460988 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 46

No results posted yet for this study

Summary

There are no studies comparing reinstrumentation and flap surgery for the treatment of residual periodontal pockets.

The aim of this RCT is to compare the re-instrumentation vs the flap surgery in terms of PD reduction, CAL gain, gingival recession, need of an additional surgery and pocket closure. Moreover, PROMs will be evaluated

Conditions

  • Periodontal Pocket
  • Periodontitis

Interventions

PROCEDURE

Flap surgery

All the sites showing a residual pocket in a sextant allocated to surgery group will receive flap surgery. After the administration of oral local anaesthesia (Articaine 1:100000) an intrasulcular flap will be raised. In order to preserve interdental tissue the flaps will be designed accordingly the principles of papillary preservation flap. Toot root will be carefully debrided using both ultrasonic instruments and Grecey's curettes. Bone recontouring and ostectomy/osteoplasty will be avoided. Single simple sutures will be used to close the flap (Vicryl 5-0).

PROCEDURE

Non surgical re-instrumentation

The sites showing remaining pockets (PD\>4mm), in the sextants allocated to re-instrumentation group, will be treated with subgingival debridement. The subgingival debridement will be performed after the administration of local oral anaesthesia (Articaine 1:100000) using a periodontal tip on ultrasonic instrument (EMS) and Gracey's curettes.
