Comparison of Microleakage among High Strength Flowable Composites Using Total Etch and Self-Etch Adhesives

Background: The recent flow-able composites available in the market claim high strength by increased filler content but their performance in micro leakage prevention in still not comparatively reported.

Aim: The aim of the study was to evaluate and compare the microleakage of five commercially available high strength flowable composite as preventive resin restoration using total etch and self-etch adhesives.

Methodology: 100 first maxillary premolars with prominent fissures were selected for the study and sealed with Filtek-Z350 XT Flow, Gaenial Universal Flow, Beautifil Flow Plus, Arabesk Flow and Grandio SO Heavy Flow.Subsequent to sealant application and embedding, the micro leakage was tested by immersing in methylene blue and subsequent stereomicroscopy.

Results: Filtek Z-350 XT was better in self-etch technique over total etch technique. Arabesk Flow and Grandio SO Heavy Flow were better in total etch technique over self-etch technique.

Conclusion: With considerations for pediatric dentistry, self-etch materials are recommended. Further clinical studies have to be carried out to draw relevant conclusions on the clinical perspectives.
