  • 摘要:
      目的  探讨二次龈下刮治术治疗牙周病的效果及对探诊深度(PD)、附着丧失(AL)、龈沟出血指数(SBI)及菌斑指数(PLI)的影响。
      方法  选取100例牙周病患者，采用摸球法分为对照组(n=50)与观察组(n=50), 分别采取牙周翻瓣术、二次龈下刮治术治疗，比较2组患者术后PD、AL、SBI及PLI变化。
      结果  术后3、6个月, 2组PD、AL、SBI、PLI指标水平较术前显著下降(P < 0.05); 2组术后3、6个月PD、AL、SBI、PLI指标水平比较无显著差异(P>0.05)。观察组牙槽骨吸收率90.0%, 与对照组牙槽骨吸收率84.0%比较无显著差异(χ2=0.354, P=0.552)。观察组牙龈退缩率6.0%, 显著低于对照组的22.0%(χ2=4.070, P=0.044)。
      结论  二次龈下刮治术治疗牙周病患者疗效确切。

     

    Abstract:
      Objective  To investigate the effect of secondary subgingival scaling on periodontal disease and its influence on probing depth (PD), attachment loss (AL), sulcus bleeding index (SBI) and plaque index (PLI).
      Methods  Totally 100 patients with periodontal disease were divided into control group (n=50) with valvuloplasty and observation group (n=50) with secondary subgingival scaling according to the ball method. Changes of PD, AL, SBI and PLI after treatment were compared between the two groups.
      Results  The levels of PD, AL, SBI and PLI in both groups decreased significantly at 3 and 6 months after operation (P < 0.05), while there were no significant differences in the levels of PD, AL, SBI and PLI between the two groups at 3 and 6 months after operation (P>0.05). The alveolar bone resorption rate of the observation group was 90.0%, which had no significant difference when compared to 84.0% of the control group (χ2=0.354, P=0.552). The gingival recession rate of the observation group was 6.0%, which was significantly lower than that 22.0% of the control group (χ2=4.070, P=0.044).
      Conclusion  Secondary subgingival scaling is effective in treating patients with periodontal disease.
