光固化复合树脂配合前牙美容修复对牙齿美观及牙周指标的影响

目的 探讨光固化复合树脂配合前牙美容修复对牙齿美观及牙周指标的影响。方法 选取2019年 1月-2022年8月在济南市口腔医院行前牙美容修复的80例患者为研究对象,按照随机数字表法分为研究 组和对照组,每组40例。对照组给予纳米复合树脂配合前牙美容修复治疗,研究组给予光固化复合树脂 配合前牙美容修复治疗,比较两组牙齿美观度、牙周指标[牙龈指数（GI）、菌斑指数（PLI）、龈沟液量 （GCF）]及并发症发生情况。结果 研究组表面光滑度、牙体形态、颜色、固位评分均低于对照组,差异 有统计学意义（ P ＜0.05）;两组治疗后3 d GI、PLI及GCF指标均低于治疗前,且研究组低于对照组,差异 有统计学意义（ P ＜0.05）;两组并发症发生率比较,差异无统计学意义（ P ＞0.05）。结论 光固化复合树 脂配合前牙美容修复可提高患者的牙齿美观度,改善牙周指标,且不会增加不良反应发生几率,安全性较 高,值得临床应用。

Effect of Light-cured Composite Resin Combined with Cosmetic Restoration of Anterior Teeth on Dental Aesthetics and Periodontal Indexes

Objective To investigate the effect of light-cured composite resin combined with cosmetic restoration of anterior teeth on dental aesthetics and periodontal indexes. Methods A total of 80 patients who underwent cosmetic restoration of anterior teeth in Jinan Stomatological Hospital from January 2019 to August 2022 were selected as the research objects. According to the random number table method, they were divided into study group and control group, with 40 cases in each group. The control group was treated with nano-composite resin combined with cosmetic restoration of anterior teeth, and the study group was treated with light-cured composite resin combined with cosmetic restoration of anterior teeth. The tooth aesthetics, periodontal indexes [gingival index (GI), plaque index (PLI), gingival crevicular fluid (GCF)] and complications were compared between the two groups. Results The surface smoothness, tooth morphology, color and retention score of the study group were lower than those of the control group, the differences were statistically significant ( P <0.05). The GI, PLI and GCF indexes of the two groups at 3 days after operation were lower than those before operation, and the study group was lower than the control group, the differences were statistically significant ( P <0.05). There was no significant difference in the incidence of complications between the two groups ( P >0.05). Conclusion Light-cured composite resin combined with cosmetic restoration of anterior teeth can improve the patient''s tooth aesthetics, improve periodontal index, and will not increase the probability of adverse reactions. It is safe and worthy of clinical application.
