3M Vitrebond光固化玻璃离子间接盖髓材料的临床应用(英文)

Clinical application of 3M Vitrebond-a light-cure glass ionomer liner/base

选取2007-06/09大连市口腔医院牙体牙髓科临床诊断为深龋近髓的102例患者184颗患牙。分为Vitrebond组54例92颗患牙和Dycal组48例92颗患牙,分别采用Vitrebond光固化玻璃离子和Dycal氢氧化钙制剂盖髓后3MZ250树脂充填。治疗后1周Vitrebond组2颗牙、Dycal组9颗牙出现牙髓症状(P<0.05)。半年追踪观察Vitrebond组1颗牙,Dycal组3颗牙充填物脱落、松动(P>0.05);Vitrebond组1颗牙,Dycal组8颗牙出现颜色差异(P<0.05)。提示3MVitrebond光固化玻璃离子在减少牙髓刺激、美观上均优于Dycal氢氧化钙制剂。

A total of 184 teeth obtained from 102 cases （27 males and 75 females aged 17-64 years） were selected from Department of Tooth and Dental Pulp, Dalian Stomatology Hospital from June to September 2007. All the teeth with deep caries which resulted from caries showed no pulp. Ninety-two teeth obtained from 54 cases were regarded as Vitrebond group which were used by light-cured glass to cover pulp; while, the other 92 teeth obtained from 48 cases were regarded as dycal group which were cured by dycal calcium hydroxide. Finally, 3MZ250 resin was used in this study. A half-year following up showed that the filling shed and loose were observed in the Vitrebond group （n=1） and the dycal group （n=3） （P 〉 0,05）. There were significant difference in color between Vitrebond group （n=1） and dycal group （n=8） （P 〈 0.05）, suggesting 3M Vitrebond light-cured glass was superior to dycal calcium hydroxide in decreasing dental pulp stimulation and improving dental appearance.
