Comparative evaluation of one-stage and multi-stages periodontal flaps in patients with localized aggressive periodontitis

Microorganism's transmission ability in the oral cavity, suggest the possibility of re-infection of treated sites by microorganisms which are still present in un-treated sites. Thus, the purpose of the present study is to evaluate the clinical results of treatment of aggressive periodontitis patients in one session and multiple stages. Twenty patients of localized aggressive periodontitis were divided in two unique groups. Test group's surgery was done within 72 h and control group's surgery in 4 sessions with one week intervals. Plaque Index (PI), Gingival Index (GI), Bleeding On Probing (BOP), Pocket Depth (PD), Clinical Attachment Level (CAL) parameters were recorded at baseline and 4 and 8 months after treatment. Collected data were analyzed with SPSS 9 software, Kolmogorov-Smirnov, Bonferroni, Student’s T, Friedman, Wilcoxon, Mann-Whitney tests. The findings showed that both treatment modalities resulted in periodontal improvements, however, GI and BOP parameters after 8 month were better in test group. Analysis of data showed pocket depth reduction in single-rooted teeth in test group, in contrast to control group was better than baseline after 8 months, yet. In multi-rooted teeth pocket depth reduction in test group was also better and more stable than control group (P<0.05) and clinical attachment gain was better and more stable. Based on this clinical study it was shown that the pocket depth reduction and attachment level gain were better and more stable in multi-rooted teeth with single stage technique. Performed surgical procedures in single –rooted teeth resulted the same pocket depth reduction and attachment level gain in both groups.
