Background & Aim: Periodontitis has a multi-factorial etiology, the success of its therapy mainly focuses on the eradication or reduction of the exogenous, and endogenous periodontopathogens. Most of the species colonize several niches within the oral cavity. This could theoretically lead to a reinfection of previously disinfected pockets by bacteria from untreated region. This study investigated clinical benefits of a one stage periodontal flap surgery versus multi stage type in the control of a moderate to advanced chronic periodontitis, over 3 & 6-month periods. Method & Materials: In a sequential randomized controlled clinical trial, twenthy patients (15 female,5 male) with moderate to advanced periodontitis were randomly divided to two groups. In test group one stage surgery within 3 days and in control group multi stages surgery in 4 consecutive weekly sesssions was performed. Probing depth (PPD), Clinical attachment level (CAL), Gingival recession (GR), Papillary bleeding index (PBI) and gingival index (GI) were recorded at baseline, 3 and 6 months afterwards, and then statistical analysis was performed.

Results: The mean overall changes in PPD and CAL in multistage surgery up to third month and in one stage at each follow up visit after 3 and 6 months resulted in significant improvement. (P<0.05) The mean changes in PPD and CAL in surgical site of both groups and in non surgical site of the one stage group and mean changes in PBI and GI in both groups at follow up visits (after 3 and 6 months) resulted in significant improvement relative to the baseline. (P<0.05) The mean overall changes in gingival recession and mean changes in surgical sites in multistage group resulted in statistically significant improvement at each follow up visits (after 3 and 6 months). (P<0.05).

Conclusion: These findings suggested that both types surgeries resulted in an improved clinical outcome for the treatment of moderate to advanced chronic periodontitis. Howere one stage surgery demonstrated more stable results in periodontal conditions over 3 and 6 months period in comparison to multi-stage surgery.
