背景/目标：以前，我们报告说，SRP导致平均袋深度和附着水平的减少，并降低患病率和水平的拟杆菌，牙龈卟啉单胞菌，齿垢密螺旋体在3个月和6个月后SRP的57例成人牙周炎。在9个月和12个月时监测了57例受试者中的32例。因此，本调查的目的是评估32（平均年龄48+/-11）科目在12个月period.Method的微生物和临床效果的SRP：临床评估菌斑，牙龈发红，化脓，出血探测，袋深度和附件水平之前，SRP和3，6，9，和12个月后治疗。龈下菌斑样本在每次访问和分析使用棋盘DNA-DNA杂交技术的存在和水平的40龈下物种。每例受试者还在每次后续监测访视时接受维持量表测量。使用Wilcoxon符号秩检验分析治疗前后临床参数和细菌种类的患病率和水平的差异。结果：平均囊袋深度（mm+/-SEM）从基线时的3.2 ± 0.3减少到12个月时的2.9 ± 0.3（p
Background/aims: Previously, we reported that SRP resulted in a decrease in mean pocket depth and attachment level and reduced prevalence and levels of Bacteroides forsythus, Porphyromonas gingivalis, and Treponema denticola at 3 and 6 months post-SRP in 57 subjects with adult periodontitis. 32 of the 57 subjects were monitored at 9 and 12 months. Thus, the purpose of the present investigation was to evaluate the microbial and clinical effects of SRP in 32 (mean age 48+/-11) subjects over a 12-month period.Method: Clinical assessments of plaque, gingival redness, suppuration, bleeding on probing, pocket depth and attachment level were made prior to SRP and at 3, 6, 9, and 12 months post-therapy. Subgingival plaque samples were taken at each visit and analyzed using the checkerboard DNA-DNA hybridization technique for the presence and levels of 40 subgingival species. Each subject also received maintenance scaling at each of the subsequent monitoring visits. Differences in clinical parameters and prevalence and levels of bacterial species were analyzed pre- and post-therapy using the Wilcoxon signed ranks test. The Quade test for related samples was used for analysis of multiple visits.Results: Mean pocket depth (mm+/-SEM) decreased from 3.2+/-0.3 at baseline to 2.9+/-0.3 at 12 months (p
