Carisolv化学去龋效果的临床研究

目的比较化学去龋与传统的机械切割去龋在临床应用中的效果差异。方法随机抽取5~8岁的乳牙唇(颊)面颈部中、深龋各20例(共40例),分为实验组和对照组,每组各20例(含中、深龋各10例),分别用Carisolv凝胶化学去龋和机械切割去龋,并在去龋效果、去尽龋所用的时间、疼痛程度、近期牙髓反应等方面用龋齿检知液及统计学分析的方法比较两者之间的差异。结果2种方法去龋效果相同,化学去龋所需要的时间多于机械切割去龋,而在去龋过程中的疼痛感觉及充填后1周的牙髓反应程度方面,化学去龋法明显小于传统的机械去龋法。结论Carisolv凝胶去龋法虽然临床操作需要较长时间,但仍是一种安全有效的无痛微创去龋新技术。

Clinical study on the effect of Carisolv as a chemomechanical caries removal agent

Objective:To study the clinical efficacy of Carisolv in caries removal.Methods:20 primary teeth with middle and 20 with deep class V caries were randomly divided into two groups.Each group contained 10 teeth with middle caries and 10 with deep caries.Carisolv was used in test group and conventional rotary instrument in the control group. Efficacy of caries removal,treatment time, the degree of the pain and the current reaction of pulp between two groups were compared.Result:The Carisolv technique and the conventional method showed the same efficacy of caries removal.The treatment time in test group was longer than that in control group(P<0.01). The degree of the pain and the current reaction of pulp in test group were significant lower than those in control group(P<0.05 and P< 0.01 ).Conclusion:Although Carisolv takes longer time in caries removal than conventional way,it is safe,effective and painless.
