目的:观察不同依从性的慢性牙周炎患者的临床治疗效果。方法:选择经牙周基础治疗4周后进入牙周维护治疗的广泛性中度慢性牙周炎患者150例作为研究对象,通过2年追踪随访、临床检查及再治疗,分析完全依从性与不完全依从性牙周炎患者的第1年、第2年临床指标(PD、AL、BOP)改变。结果:完全依从性组的牙周探诊深度、探诊后出血率在第1、第2年均较基线明显下降,差异有统计学意义(P<0.001),附着丧失均值有所下降,差异有统计学意义(P<0.001);不完全依从性组牙周探诊深度、探诊后出血率、附着丧失在第1、第2年均值较基线明显增高,达到初诊水平,差异有统计学意义(P<0.001);在第1、第2年AL≥1 mm位点百分比及活动性进展率较基线均有提高,差异有统计学意义(P<0.001)。结论:完全依从性慢性牙周炎患者疗效稳定持久;不完全依从性慢性牙周炎患者疗效较差,活动性发生率较高。
Objective: To observe the clinical effects of different compliance chronic periodontitis patients. Methods: A total of 150 patients with extensive chronic chronic periodontitis who entered the periodontal maintenance treatment after 4 weeks of periodontal basic treatment were chosen as the research object. Through 2-year follow-up, clinical examination and re-treatment, the complete compliance and no Patients with complete compliance with periodontitis at 1 year, 2 years of clinical indicators (PD, AL, BOP) changes. Results: The total length of periodontal exploration in complete compliance group and the bleeding rate in the first and second years after treatment were significantly lower than those in baseline (P <0.001), and the mean value of attachment loss decreased (P <0.001). In incomplete compliance group, the depth of periodontal exploration, the rate of bleeding after probing, the mean loss of adhesion in the first and second year were significantly higher than those of the baseline, reaching the first visit, the difference was statistically significant (P <0.001). In the first and second years, the percentage of AL≥1 mm and the rate of activity progression were all significantly higher than those of the baseline (P <0.001). Conclusion: The complete compliance of patients with chronic periodontitis has a stable and long-lasting effect. Patients with incomplete compliance have worse curative effect and higher incidence of active periodontitis.
