摘要
目的:对目前常用的排龈药物的排龈效果进行评价,为临床排龈药物的应用提供参考。方法:选择200例单个上前牙缺损的患者,按就诊次序随机分组,应用不同实验药物排龈,以量化打分来评价排龈效果的优劣。结果:3种排龈药物总积分与不含药组总积分有显著性差异(P<0.05),3种药物总积分无显著性差异(P=0.365);各组唇侧与腭侧积分均有显著性差异(P<0.05)。结论:药物排龈效果比单纯棉线排龈效果好,可以推广应用,而3种药物排龈效果无明显差别;在设计腭侧肩台时,尽量把肩台设计在龈上,这有利于基牙预备体肩台的清晰度。
Objective: To compare the effect of different gingival retraction agents on gingival retraction. Methods: 200 patients with single upper anterior missing tooth were randomly grouped according to the visiting sequence. Different agents were applied to retract gingival and the results were evaluated quantificationally. Results: The grade of 3 kinds of agents groups was different from the group containing no agent (P〈0.05). The grade among the 3 kinds of agents had no significant difference. The grade of the buccal side and palatal side was different in every group. Conclusion: Gingival retraction effect is better when the cord contains retraction agents. Supragingival shoulder on palatal side is recommended to improve the marginal definition of preparations.
