目的:根据磨牙中重度慢性牙周炎发生不同部位病变比较非手术治疗的疗效。方法:根据单个磨牙深牙周袋发生的部位(颊侧或舌/腭侧)将收集的上、下颌磨牙各分为两组(上颌I组、上颌II组、下颌I组、下颌II组),观察各组治疗前后牙周指标的变化,比较疗效差异。结果:4组病例治疗后6周各项牙周指标均较基线有明显改善,差异有显著性(P<0.01)。上颌两组间及下颌两组间比较,可见6周时上颌II组的PD、BI、CAL均高于上颌I组,差异有显著性(P<0.01);下颌II组的PD、BI、CAL高于下颌I组,差异有显著性(P<0.01)。结论:发生在磨牙的牙周炎症无论是上颌还是下颌,颊侧病变的预后均好于舌/腭侧,差异有显著性。
Objective: To compare the efficacy of non-surgical treatment according to the different parts of the lesions of severe chronic periodontitis. Methods: The upper and lower mandibular molars were divided into two groups (maxillary I group, maxillary II group, mandibular I group, mandibular II group) according to the site (buccal or lingual / palatal side) The changes of periodontal index in each group before and after treatment were observed, and the differences in curative effect were compared. Results: The periodontal indexes of the four groups were significantly improved compared with the baseline at 6 weeks after treatment, the difference was significant (P <0.01). There were significant differences in PD, BI and CAL in maxillary group II between the two groups (P <0.01). The PD, BI and CAL in maxillary group II at 6 weeks were significantly higher than those in maxillary I group Higher than the mandibular I group, the difference was significant (P <0.01). Conclusion: The periodontal inflammation in molars, whether upper or lower jaw, the prognosis of buccal lesions are better than the tongue / palatal side, the difference was significant.
