Clinical Evaluation of Flowable Composites in Cervical Lesions: 18-Month Results

OBJECTIVES: The purpose of this study was to evaluate the 18-month clinical performance of one microhybrid and three different types of flowable resin composites in noncarious cervical lesions. METHODS: A total of 252 noncarious cervical lesions were restored with Admira Flow (Voco,Germany), Dyract Flow(Dentsply,Germany), Filtek Flow(3M/Espe,USA) and Filtek Z250(3M/Espe, USA) according to manufacturers' instructions in 37 patients(25 Female, 12 Male). All restorations were placed by one operator. The restorations were evaluated clinically within 1 week after placement and after 6, 12, 18 months using modified USPHS criteria by two other examiners. The data were analyzed with Chi-square and McNemar tests(p<0,05). RESULTS: At the end of 18 months; 212 restorations were evaluated with a recall rate of 84%. Significant difference was found between Admira Flow and Dyract Flow for color match and marginal discoloration. No significant difference was demonstrated for marginal adaptation, anatomical form, seconder caries and surface texture between the resin composites. Totally 23 restorations were lost and the retention rate was 90% and in this criteria there was no significant difference between the materials. CONCLUSION: It was concluded that; in this study flowable composite resins demonstrated acceptable clinical performance in non-carious cervical lesions after 18 months. However; further evaluations are necessary for the long-term clinical performance of these materials.
