A 12-Month Clinical Evaluation of Three Different Universal Adhesives in the Restoration of Non-Carious Cervical Lesions
Objectives: The aim of this randomized, controlled prospective clinical trial was to evaluate and compare the performances of three different universal adhesives using a flowable universal composite resin in the restoration of non-carious cervical lesions (NCCL) over 12-month period.
Methods: Eighteen participants recieved 99 restorations from a single operator. NCCLs were divided into three groups according to adhesive systems used:Clearfil Universal(CU), Ibond(IB) and G-Premio Bond(GP). No enamel bevel was placed and no mechanical retention was created for the NCCLs. Prior to adhesive procedures, selective etching was performed with %37 phosphoric acid. Adhesive systems were applied following manufacturers’ instructions and the lesions were restored with a flowable composite resin (Geanial Flowable Universal). Restorations were finished and polished immediately after placement and scored with regard to retention, marginal discoloration, marginal adaptation, sensitivity, surface texture and color match using modified USPHS criteria after a week(baseline) and 6 and 12 months. Descriptive statistics were performed using Chi-square tests.
Results: The 6 and 12-month recall rates were 100%. Retention rates for the three groups were also 100% at both evaluations. No restorations exibited post operative sensitivity in 6- and 12-month observations. After 6 months, 2 GP restorations recieved bravo scores for marginal adaptation, 1 GP restoration recieved bravo score for marginal discoloration and 2 CU restorations recieved bravo scores for surface texture and color match. At 12-month evaluation, 2 CU, 3 IB and 5 GP restorations showed bravo scores for marginal adaptation whereas only 3 IB and 3 CP restorations showed bravo for marginal discoloration. A total of 10 (CU:2,IU:3,GP:5) restorations exhibited bravo scores for surface texture and 3 (CU:2, GP:1) restorations showed bravo score for color match. No statistical differences were found among the tested adhesives for any criteria evaluated(p>0.05).
Conclusions: The three adhesive systems demonstrated similar performances during 12-month follow-up in the restoration of NCCLs.
