原花青素联合Nd:YAG激光对牙本质小管的封闭能力及牙本质粘接效果研究
Study on the sealing ability and bonding effect of proanthocyanidins and Nd:YAG laser on dentinal tubules
摘要
Abstract
Objective:To explore the effect of using proanthocyanidins(PA)and Nd:YAG laser on the sealing ability and dentin adhesion desensitization in the occlusion of dentinal tubules.Methods:Thirty healthy extracted molars collected from Hengshui Fourth People's Hospital were selected,and 60 dentin samples were obtained after treatment.They were ran-domly divided into three groups:PA group(n=20,PA treatment),laser group(n=20,Nd:YAG laser treatment),and com-bined group(n=20,PA+Nd:YAG laser).The diameter and relative area of dentinal tubules,closure,permeability,acid cor-rosion resistance,and dentin bonding strength in three groups were compared.Results:In comparison of the PA group and la-ser group,the diameter and relative area of dentinal tubules in the combined group were smaller(P<0.05),and in compari-son of the PA group,those in the laser group were smaller(P<0.05).In comparison of the PA group and laser group,the sealing depth in the combined group was greater,sealing rate was higher(P<0.05),in comparison of the PA group,the seal-ing depth in the laser group was greater,and sealing rate was higher(P<0.05).In comparison of the PA group and laser group,the penetration depth in the combined group was greater(P<0.05),and in comparison of the PA group,that of the la-ser group were greater(P<0.05).There were differences in the comparison of acid corrosion resistance between the three groups,time,and interaction(P<0.05).Intra group comparison:10 min and 15 min were lower than 5 min,and 15 min was lower than 10 min(P<0.05).Comparison between groups:in comparison of the PA group and the laser group,the combined group was higher at each time period(P<0.05),and in comparison of the PA group,the laser group was higher(P<0.05).In comparison of the PA group and the laser group,the bonding strength of the combined group was higher(P<0.05),and in comparison of the PA group,the laser group was higher(P<0.05).Conclusion:PA and Nd:YAG laser can reduce the diam-eter and relative area of dentinal tubules,improve the sealing and permeability,and promote the improvement of acid corrosion resistance,and dentin bonding strength.关键词
