目的探讨牙周基础治疗在伴张口呼吸牙周病中的应用效果。方法 67例存在张口呼吸习惯的慢性牙周病患者为研究对象,均予以牙周基础治疗方案。记录其治疗前后菌斑指数、出血指数及探诊深度等指标变化差异。结果治疗后,大部分受试患者菌斑指数、出血指数及探诊深度示值均较治疗前显著减少,差异具有统计学意义(P<0.05),口腔健康状况理想。结论对伴张口呼吸习惯的慢性牙周病患者予以牙周基础治疗措施,疗效显著,值得临床推广。 Objective To investigate the effect of basic periodontal treatment on periodontal disease with mouth-breathing. Methods Sixty-seven patients with chronic periodontal disease who had oral breathing habits were enrolled in this study. All patients were given basic periodontal treatment. Record before and after treatment, plaque index, hemorrhage index and exploration depth and other indicators of change. Results After treatment, the plaque index, hemorrhage index and depth of exploration in most of the patients were significantly lower than those before treatment, the difference was statistically significant (P <0.05), the oral health was satisfactory. Conclusions The basic periodontal treatment of chronic periodontal disease patients with mouth breathing habits is given, and the curative effect is significant, which is worthy of clinical promotion.
