Improvement of Periodontal Parameters in Untreated site After Periodontal Surgery at Adjacent sites

ABSTRACT: The aim of this study was to find out whether surgical treatments performed on each quadrant would have any influence on the periodontal status of the untreated quadrants. 25 patients with severe chronic periodontitis were selected and received full-mouth scaling and root planning. After 8 weeks, quadrant-wise surgery was performed during four consecutive sessions at 2-week intervals for sites with probing pocket depth (PPD)>5 mm and bleeding on probing (BOP). Clinical parameters including PPD, BOP, and clinical attachment level were recorded at baseline, session prior to surgery, and 8 weeks after last surgical visit. The mean PD of pockets>3mm was reduced from 4.09±1.32 mm at baseline to 1.37±0.87 mm at the end of the study. Although the data from visit six (8 weeks after surgery in quadrant four) showed significant differences compared to those from all other visits. Pockets with a baseline depth of 5 mm>PPD>3 mm, 7 mm> PPD ≥ 5 mm, and PPD≥7 mm showed reductions from 3.55±0.35 mm, 4.17±0.22 mm, 7.19±0.54mm, respectively, at baseline to1.18±0.97 mm, 1.35±0.50 mm, 2.64±0.38 mm, respectively, at the end of the study. Overall, mean PAL improved from 4.13±1.37 mm to 3.35±0.83 mm at visit five and decreased slightly to 3.05±0.34 mm after the last visit. BOP decreased from 88.65%±25.25 % at baseline to 8.97%±10.67 % at the end of study. There was a marked difference between the BOP scores of visits one, two, and three and those of visits four and five. Also, a remarkabl
