目的:评价排龈膏和排龈线在固定义齿修复中对牙龈保护、牙体预备、印模清晰度及修复体适合性的作用。方法:检索中国生物医学文献数据库、维普数据库、中国期刊全文数据库和万方数据库;同时手工检索纳入文献的参考文献及中文口腔医学杂志。偏倚风险评价由2位评价者使用Cochrane协作网推荐的标准独立完成,同时独立进行数据提取。运用Revman 5.1软件进行Meta分析。结果:共纳入9篇随机对照试验,涉及患者1153例,9个研究均为中度偏倚风险。Meta分析结果显示,排龈膏能够明显保护基牙牙龈健康[RR=1.05,95%CI(1.00,1.11),P=0.04],提高临床医师对牙体预备满意度[RR=1.17,95%CI(1.07,1.28),P=0.0008],提高印模及模型清晰度[RR=1.08,95%CI(1.03,1.13),P=0.0009],且与排龈线相比,有相似的修复体适合性[RR=1.07,95%CI(0.96,1.19),P=0.21]。结论:排龈膏在保护基牙牙龈健康、提高口腔医师对牙体预备满意度和提高印模及模型清晰度方面优于传统排龈线,在提高修复体适合性上也不逊色于传统排龈线,但还需要多的临床随机对照试验予以验证。
OBJECTIVE: To evaluate the effect of row gingival crevicular line and gingival retraction line on gingival protection, dental preparation, impression clarity and prosthesis fit during prosthetic restoration. Methods: The Chinese biomedical literature database, VIP database, Chinese periodical full-text database and Wanfang database were searched. At the same time, the references and the Chinese Journal of Stomatology were searched manually. The bias risk assessment was independently performed by two reviewers using the Cochrane Collaboration recommended standards, with independent data extraction. Meta-analysis using Revman 5.1 software. Results: A total of 9 randomized controlled trials involving 1153 patients were included, all of which were at moderate risk of bias. The results of Meta analysis showed that the row gingival ointment significantly protected gums of abutments (RR = 1.05,95% CI (1.00,1.11), P = 0.04], and improved the satisfaction of clinicians on tooth preparation [RR = 1.17, 95% (RR = 1.08, 95% CI (1.03, 1.13), P = 0.0009] compared with those of the gingival retraction line (CI = 1.07,1.28, P = 0.0008) Body suitability [RR = 1.07, 95% CI (0.96, 1.19), P = 0.21]. Conclusion: Gingivalgia gingivalis is superior to conventional gingival retraction line in protecting gingival health of dental abutments, improving dentist’s satisfaction with dental preparation and improving impression and model definition, and is not inferior to traditional gingival retraction in improving fit of prosthesis Gingival line, but also need more clinical randomized controlled trials to be verified.
