To study the clinical performance of two candidates for improvement of the original Gluma bonding system.
Eight teeth with cervical buccal abrasion/erosion lesions were identified in 40 patients. The lesions were conditioned with an oxalic acid solution followed by either a HEMA-glutaraldehyde bonding agent or a formamide-containing bonding agent. The lesions were restored with a hybrid composite. Each patient received the same number of restorations with the two different bonding formulations. All restorations were made by the same operator (JK). Evaluations were based on the USPHS system.
No difference between the two groups as to retention, marginal adaptation and discoloration was observed after 3 years. Eight restorations were lost and a slight increase in marginal discoloration was seen during the observation period.
研究两种用于改进原始Gluma粘结系统的材料的临床性能。
在40名患者中确定了8颗患有颈部颊侧磨损/侵蚀性病变的牙齿。先用草酸溶液对病变进行预处理,然后分别使用甲基丙烯酸羟乙酯-戊二醛粘结剂或含甲酰胺的粘结剂。用混合复合材料修复病变。每位患者接受相同数量的使用两种不同粘结配方的修复体。所有修复体均由同一名操作者(JK)制作。评估基于美国公共卫生服务(USPHS)系统。
3年后,两组在固位、边缘适应性和变色方面未观察到差异。在观察期内,有8个修复体脱落,边缘变色略有增加。
