Abstract
Background and objectiveManagement of combined endodontic–periodontal lesions needs more clinical investigations. The aim of this prospective randomized clinical trial was to evaluate the effect oftime interval between the non-surgical endodontic treatment (ET) and open flap debridement (OFD) on periodontal healing in combined endodontic periodontal lesions with apical communication. MethodsForty patients were randomly allocated to two treatment protocols. Group 1(immediate periodontal surgery): OFD was performed at 21days of initiation of ET and SRP, and Group 2(delayed periodontal surgery): OFD was performed after 3 months of initiation of ET and SRP. The primary parameters included probing pocket depth (PPD), relative attachment level (RAL) and bleeding on probing (BOP) and tooth mobility (TM). ResultsSignificantly more reduction in PPD, TM and gain in RAL was observed in Group 1 at 3 months of OFD. (P<0.05) Whereas at 6 months follow up of OFD (6 and 9 months of ET in Group1 and Group 2, respectively), intergroup analysis showed statistically comparable reduction in BOP (%), PPD, TM and gain in RAL (P>0.05) in both the groups. ConclusionImmediate periodontal surgery may not affect the outcome of the treatment of combined endo-perio lesions with apical communication.
