RESUMO

The purpose of this study was to assess the clinical performance of a monocomponent adhesive system (Excite/Tetric-Ceram Vivadent) and a resin-modified glass ionomer cement (Vitremer – 3M) to restore non-carious cervical lesions using a modified USPHS system. A total of 70 restorations (thirty-five per material) were performed by one operator in 30 patients 23-68 aged. Prior to restorations, teeth were pumiced with a prophy cup and restored following manufacturer’s instructions. All restorations were directly evaluated by two examiners at baseline, 6 months, 1 year and 2 years using the following: retention, marginal integrity, marginal discoloration, wear, recurrent caries postoperative and sensitivity. After two years. The ratings (Alpha and Bravo) of clinical satisfactory restorations were as follows (Tetric-Ceram/Vitremer): retention (79%/100%), marginal integrity (100%/100%), marginal discoloration (100%/100%), wear (96%/100%), recurrent caries (100%/100%) and postoperative sensitivity (100%/100%). Statistical analysis was completed with Fisher’s exact or Pearson Chi-square tests at a significance level of 5% (P<0.05). Intra-groups comparison was completed with McNemar’s test at a significance level of 5% (P<0.05). Results showed that all restorations of resinmodified glass ionomer cement were clinically satisfactory and there was significant difference between materials in retention criterion at 2 years of evaluation.
