Abstract
Objectives: The purpose of this study was to determine bond strength of three self-adhering flowable composites. Materials and Methods: Mean tensile bond strength was measured in three groups – Group A – Constic, Group B – Dyad Flow, and Group C – Fusio Liquid Dentin on sound and demineralized primary teeth. Fracture pattern was studied using a stereomicroscope for each sample and in classified as adhesive, cohesive, or mixed fracture. Results: Mean tensile bond strength in sound enamel of Group A (Constic) was found to be 10.79 + 4.24, Group B (Dyad Flow) was 10.30 + 4.63, and of Group C (Fusio Liquid Dentine) was 11.87 + 4.45. No significant difference was found between the three groups (f = 0.327 and P = 0.724). However, a significant difference was found with demineralized enamel in three groups. Constic and Dyad Flow exhibited adhesive fracture pattern in majority of samples on sound enamel, whereas Fusio Liquid Dentin had mixed fracture pattern. On demineralized enamel, Constic exhibited adhesive fracture pattern majorly, whereas Dyad flow demonstrated mixed pattern and Fusio Liquid Dentin had more of cohesive fractures. Conclusion: Constic, Dyad Flow, and Fusio Liquid Dentin can be used instead of conventional pit and fissure sealants or in small occlusal cavities in primary teeth as a single step material.Keywords
