Sažetak:
Aim. The aim of the study was to compare penetration and marginal sealing ability of the resin sealant and flowable composite subjected to thermal and mechanical cycling. Methods. The sample (49 teeth) was divided in 4 groups. The fissures were sealed with Concise White Sealant Light Cure (CWS)(3M ESPE) or Tetric Flow (Ivoclar-Vivadent AG): Group 1 and 2 were etched with 37% H3PO4 for 30s, rinsed & dryed for 15s, and CWS was applied. In group 3 and 4 samples were etched with 37% H3PO4 for 30s, rinsed & dryed for 15s, and Tetric Flow applied. Sealants were polymerized 20 s in all groups. All samples were thermocycled (1800 cycles, 5-55° C, dwell time 10 s). After thermocycling groups 2 and 4 were subjected to fatigue with load application (5000 cycles, force 100N, 1Hz frequency). Microleakage was tested with 50% AgNO3 dye. Teeth were sectioned and photographed under light microscopy (Olympus ; 10x). Values of microleakage were scored with method described by Övrebö and Raadal (1990). Results. Penetration in the fissures was 82 - 92% with significantly lower values for flowable composite (p=0.002). There was no significant difference in leakage between groups with or without mechanical cycling (CWS p=0.81 ; Tetric flow p=0.17). No significant difference between groups with only mechanical cycling was observed (p = 0.85). Conclusion. Both tested materials showed good performance after thermal and mechanical cycling. Penetration of Tetric Flow in the fissures was significantly lower. Using flowable composite as the sealing material can be interesting alternative that deserves further research.
