牙周炎患者种植义齿修复后口腔自我维护的临床观察

目的：探讨菌斑显示剂在牙周炎患者种植义齿修复后口腔维护中的作用。方法整群选择2013年5月—2015年2月在医院进行义齿修复的62例患者共78颗种植体作为研究对象，随机分为观察组和对照组，每组31例39颗种植体。在修复后的口腔自我维护中，对照组给予一般维护，观察组在此基础上给予菌斑显示剂，比较两组患者的牙周参数和种植体周围黏膜炎发生率。结果种植体完成修复2周后，两组患者PLI、SBI、PD和菌斑指数与对照组相较差异无统计学意义(P>0.05)；修复3个月后所有患者观察组PLI、SBI、PD和菌斑指数均优于对照组(P<0.05)；种植修复后1年内，观察组种植体周围粘膜炎平均发生率为45.6%，对照组为59.4%，差异有统计学意义(P<0.05)。结论系统的口腔自我维护能够显著降低牙周炎患者种植体周围黏膜炎的发生率，使用菌斑显示剂让患者对菌斑有良好的自我控制效果显著。

Clinical Observation of Oral Self-maintenance after Implant Denture Repair in Periodontitis Patients

Objective To investigate the effect of dental plaque disclosing agent on oral maintenance in patients with peri-odontitis after implant denture repair. Methods 62 patients underwent implant denture repair with 78 implants in total in the hospital from May 2013 to February 2015 were selected as the subjects and randomly divided into observation group and control group, with 31 patients and 39 implants in each group. For the oral self-maintenance, both groups were given the general maintenance, in addition, the observation group were given dental plaque disclosing agent. And the periodontal parameters and incidence of peri-implant mucositis of the two groups were compared. Results Two weeks after the implant denture repair, the difference in PLI, SBI, PD and dental plaque indexes between the two groups had no statistical signifi-cance(P>0.05). Three months after the repair, these indexes for patients in the observation group were better than those in the control group(P<0.05). And within 1 year after the implant repair, the incidence of peri-implant mucositis was 45.6% in the observation group and 59.4% in the control group, the difference had statistical significance(P<0.05). Conclusion Sys-tematic oral self-maintenance can obviously reduce the incidence of peri-implant mucositis. Dental plaque disclosing agent has good self-control effects on the plaque in the patients.
