摘要
目的:探讨减数正畸联合牙周系统治疗对重度牙周炎错颌畸形患者牙周相关指标及牙槽骨高度的影响。方法:80例重度牙周炎错颌畸形患者(共168颗减数牙)均给予减数正畸联合牙周系统治疗,并与336颗减数牙邻牙和336颗对照牙相对比。比较治疗前后牙周相关指标[探诊深度(PD)、龈沟出血指数(SBI)]、牙槽骨高度[相对骨高度(RBH)]、龈沟液炎症因子[白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)]水平及牙根吸收情况。结果:与矫治前比较,矫治后减数牙邻牙及对照牙PD、SBI比较,差异无统计学意义(P>0.05);矫治前与矫治后,减数牙邻牙与对照牙PD、SBI比较,差异均无统计学意义(P>0.05)。矫治前,减数牙邻牙与对照牙RBH比较,差异无统计学意义(P>0.05);矫治后,对照牙RBH与矫治前比较,无统计学差异(P>0.05),减数牙邻牙RBH大于矫治前(P<0.05),但与对照牙RBH比较,差异无统计学意义(P>0.05)。矫治前,减数牙邻牙近、远减数侧RBH差异无统计学意义(P>0.05);矫治后,减数牙邻牙近减数侧RBH与矫治前比较,差异无统计学意义(P>0.05),但小于远减数侧RBH(P<0.05),远减数侧RBH大于矫治前(P<0.05),患者龈沟液IL-6、TNF-α水平低于矫治前(P<0.05),减数牙邻牙牙根吸收百分比为12.8%,高于对照组的4.4%(Z=8.752,P<0.05)。结论:减数正畸联合牙周系统治疗没有对重度牙周炎错颌畸形患者牙周组织造成明显影响,在一定程度上提升减数牙邻牙牙槽骨高度。
Objective:To investigate the effects of reduced orthodontics combined with periodontal system treatment on periodontal parameters and alveolar bone height in patients with malocclusion of severe periodontitis.Methods:80 patients with malocclusion of severe periodontitis(168 reduced teeth in total)were treated with reduced orthodontics combined with periodontal system,and compared with 336 adjacent teeth and 336 control teeth.The periodontal related indicators[probing depth(PD),sulcus bleeding index(SBI)],alveolar bone height[relative bone height(RBH)],the level of inflammatory cytokines[interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)]in the gingival-crevicular fluid and root resorption were compared before and after treatment.Results:There was no significant difference in PD and SBI between the adjacent teeth and the control teeth after treatment(P>0.05).There was no significant difference in PD and SBI between the adjacent teeth and the control teeth before and after treatment(P>0.05).Before treatment,there was no significant difference in RBH between the adjacent teeth of the reduced teeth and the control teeth(P>0.05).After treatment,the RBH of the control teeth was not significantly different from that before treatment(P>0.05).The RBH of the adjacent teeth of the reduced teeth was greater than that before treatment(P<0.05),but there was no significant difference from that of the control teeth(P>0.05).Before treatment,there was no significant difference in RBH between the proximal and distal sides of the reduced teeth(P>0.05).After treatment,there was no significant difference between the RBH of the proximal side of the reduced teeth and that of the anterior side(P>0.05),but it was smaller than that of the distal side(P<0.05).The RBH in the distal decrement side after treatment was greater than that before treatment(P<0.05).After treatment,the levels of IL-6 and TNF-αin the gingival crevicular fluid were lower than those before treatment(P<0.05).After treatment,the percentage of root resorption of adjacent teeth of the reduced teeth was 12.8%,which was higher than 4.4%of the control group(Z=8.752,P<0.05).Conclusion:Reduction orthodontics combined with periodontal system treatment has no significant impact on the periodontal tissue of patients with severe periodontitis malocclusion,and will improve the alveolar bone height of the adjacent teeth of the reduced teeth to a certain extent.
