To determine whether the use of Gluma as a desensitizing agent on tooth preparations has any effect upon the bond strength of a resin composite restoration cemented to dentin.
Forty extracted human molars which were caries and restoration-free were occlusally reduced to remove enamel. Twenty of the teeth received a Gluma desensitization treatment and 20 were untreated (controls). Following a 7-day storage period, simulated resin composite inlays were bonded to all of the dentin specimens, using either All-Bond 2 with All-Bond Crown & Bridge Cement or OptiBond with Porcelite Dual Cure. Twenty-four hours later, the shear bond strength of the specimens was determined.
Statistical analysis (paired t-tests) indicated no significant difference in bond strength for Gluma-treated specimens when compared to controls, for either bonding material.
确定在牙齿预备时使用Gluma脱敏剂对粘结于牙本质的树脂复合材料修复体的粘结强度是否有任何影响。
选取40颗无龋坏且无修复体的拔除人磨牙，从咬合面磨除釉质。其中20颗牙齿接受Gluma脱敏治疗，20颗未治疗（作为对照）。经过7天的储存期后，使用全粘结2粘结剂与全粘结冠桥粘结剂或OptiBond粘结剂与Porcelite双固化剂，将模拟树脂复合材料嵌体粘结到所有牙本质标本上。24小时后，测定标本的剪切粘结强度。
统计分析（配对t检验）表明，对于两种粘结材料中的任何一种，与对照组相比，经Gluma处理的标本的粘结强度均无显著差异。
