In-vivo Comparison of Flowable Composites and Fissure Sealants

Objectives: The aim of this study was to compare the clinical performance of flowable composite and fissure sealants, after 2 years in stress-bearing occlusal surfaces. Methods: Totally 34 patients (15,4 ± 4,1), 14 female and 20 male, were enrolled in the study. Overall 104 fissures were restored either flowable composite Admira Flow (AF, Voco) or fissure sealant Fissurit F (FF, Voco). At least two fissures were restored each patient and each restoratives were applied for each patient by one operator. Restorations (50 for AF, 54 for FF) were evaluated by other two examiners and the data were recorded according to the modified USPHS criteria. Double-blinded test were performed at baseline, after 12-month and after 24-month. Obtained data were statistically analyzed by Fisher’s exact test. Results: The cumulative retention rates were %99, %96,5 and % 84,2 for AF and %99, % 94,5 and % 87,8 for FF at baseline, at 12-month recall and at 24-month recall, respectively. There were no statistical significant differences were found. At the end of the 24-month period of time, eight restorations with marginal discoloration received a score of Charlie in AF group and seven restorations were lost in group FF. While the main problem was margin discoloration for AF group, wear and the retention failures were the main problem for FF group. Conclusions: After 2 years, the restorative materials performed clinically well at the occlusal surfaces. Hence we concluded the obtaining results; flowable composite may be recommended for sealing fissures especially at the stress-bearing areas.
