目的:探讨氧化锆全瓷冠修复后牙周组织的效果。方法:选取于2015年1月至2016年12月就诊于江门市口腔医院的隐裂性牙髓病患者50例,随机分组为两组,对照组采用金属瓷冠修复方式,观察组采用氧化锆全瓷冠修复方式。评估两组患者的修复效果和预后情况,统计修复优良率、并发症发生率及炎症疼痛程度,并且采用自制的调查表调查患者的满意度,予以对比。结果:(1)和对照组对比,观察组修复优良率(92%)和患者满意度(100%)明显更高,并发症发生率(4%)明显更低,数据比较差异具有统计学意义(P<0.05)。(2)与对照组对比,观察组缓解率明显更高,比较差异具有统计学意义(P<0.05);其中观察组无疼痛、轻度患者比对照组明显更多,中度疼痛、重度疼痛患者比对照组明显更少,比较差异具有统计学意义(P<0.05)。结论:氧化锆全瓷冠修复后牙周组织的效果显著,并发症少,能够提高患者的满意度。
Objective: To investigate the effect of zirconia ceramic crowns on periodontal tissues. Methods: From January 2015 to December 2016, 50 patients with cryptogenic endodontic disease who were treated in Jiangmen Stomatological Hospital were randomly divided into two groups. The control group was treated with metal porcelain crown. The observation group was treated with zirconia All-ceramic crown repair. The repair effect and prognosis of two groups of patients were evaluated. The excellent rate of repair, the incidence of complications and the degree of inflammatory pain were calculated. The self-made questionnaire was used to investigate the satisfaction of the patients, and compared. Results: (1) Compared with the control group, the recovery rate of the observation group was significantly higher (92%) and patient satisfaction (100%), the complication rate was significantly lower (4%), the difference was statistically significant (P <0.05). (2) Compared with the control group, the remission rate of the observation group was significantly higher, the difference was statistically significant (P <0.05); in the observation group there was no pain, mild patients were significantly more than the control group, moderate pain, severe pain Patients were significantly less than the control group, the difference was statistically significant (P <0.05). Conclusion: The effect of periodontal tissue repaired by zirconia all-ceramic crowns is significant with fewer complications and can improve patient satisfaction.
