The aim of this study was to assess the clinical performance of two adhesive restorative systems (Single Bond/Filtek P-60 and Single Bond/Filtek Z-250) in posterior teeth using a modified United States Public Health Service (USPHS) system.
A total of 70 restorations were placed in molars and premolars in 30 patients (14 females and 16 males; 18-40 years) by one operator. All restorations were directly evaluated by two examiners at baseline, six months, and 12 months using the following modified USPHS rating criteria: marginal integrity, marginal discoloration, surface texture, contour, postoperative sensitivity, and recurrent caries.
At six and 12 months all restorations were available for evaluation of marginal discoloration, surface texture, contour, postoperative sensitivity, and recurrent caries that remained with 100% Alpha-ratings at recalls for both restorative systems. Marginal integrity for P-60 was scored as 94.3% and 91.4% Alpha at six and 12 months, respectively, and rates for Z-250 were 100% and 97.1% Alpha at six and 12 months, respectively. Statistical analysis was completed with Fisher's exact and McNemar Chi-square tests at a significance level of 5% (P<0.05).
All restorations were clinically satisfactory and no significant differences were found among them.
Posterior resin composite restorations placed under appropriate conditions provide a satisfactory clinical performance.
本研究旨在使用改良的美国公共卫生服务(USPHS)系统评估两种粘结修复系统(单键/3M Filtek P-60和单键/3M Filtek Z-250)在后牙中的临床性能。
由一名操作人员在30名患者(14名女性和16名男性;年龄18 - 40岁)的磨牙和前磨牙中放置了总共70个修复体。在基线、6个月和12个月时,由两名检查人员使用以下改良的USPHS评级标准对所有修复体进行直接评估:边缘完整性、边缘变色、表面质地、外形、术后敏感性和继发龋。
在6个月和12个月时,所有修复体均可用于评估边缘变色、表面质地、外形、术后敏感性和继发龋,两种修复系统在复查时这些指标均保持100%的A级评分。P-60修复体边缘完整性在6个月和12个月时的A级评分分别为94.3%和91.4%,Z-250修复体在6个月和12个月时的A级评分分别为100%和97.1%。采用Fisher精确检验和McNemar卡方检验进行统计学分析,显著性水平为5%(P<0.05)。
所有修复体在临床上均令人满意,且它们之间未发现显著差异。
在适当条件下放置的后牙树脂复合修复体具有令人满意的临床性能。
