The objective of this study was to compare the efficacy of supportive periodontal therapy (i.e. scaling and rooth planning, SRP) alone versus a chemical device silica dioxide (SiO2) colloidal solutions (SL) used in association with SRP in the treatment of chronic periodontitis in adult patients.
A total of 20 patients with a diagnosis of chronic periodontitis (40 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients have previously received any surgical or non-surgical periodontal therapy and demonstrated radiographic evidence of moderate bone loss. Two non-adjacent sites in separate quadrants were selected in each patient to monitorize treatment efficacy (split mouth design). Clinical pocket depth (PD) and microbial analysis (MA) were analyzed at baseline and 15th day. SPSS program and paired simple statistic T-test were used to detect significant differences.
Total bacteria loading, Tannerella Forsitia and Treponema Denticola loading were statistically reduced when SiO2 is locally delivered.
SL gel is an adiuvant therapy which should be added to SRP in the management of moderate to severe chronic periodontitis.
本研究旨在比较单独使用支持性牙周治疗（即洁治和根面平整，SRP）与将二氧化硅（SiO2）胶体溶液（SL）化学器械联合 SRP 治疗成人慢性牙周炎的疗效。
选择了年龄在 35 至 55 岁之间的 20 名患有慢性牙周炎（40 个局部慢性牙周炎部位）的患者。这些患者均未接受过任何手术或非手术牙周治疗，并且具有中度骨丧失的放射影像学证据。每位患者选择两个位于不同象限的非相邻部位来监测治疗效果（分组设计）。在基线和第 15 天分析临床牙周袋深度（PD）和微生物分析（MA）。使用 SPSS 程序和配对简单统计 T 检验来检测显著差异。
当局部给予 SiO2 时，总细菌负荷、Tannerella Forsitia 和 Treponema Denticola 负荷均有统计学降低。
SL 凝胶是一种辅助治疗方法，应在中重度慢性牙周炎的管理中添加到 SRP 中。
