Sealing Ability of Nano Hybrid Bulk Fill Composites and High Strength Posterior Glass Ionomer Cements in Restoring Class V Lesions - A Microleakage Study
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2017, Vol 20, Issue 3
Abstract
Aim: The aim of the study was to evaluate the microleakage of nano hybrid composite (Tetric N ceram- bulk fill, Ivoclar Vivident, USA) and high strength glass ionomer (GC Fuji IX, GC corporation, Tokyo, Japan) in class V restorations using a dye leakage model. Study Design: Study design included dye penetration model and observing the samples under Stereomicroscope at 20X magnification. Place and Duration: The study was conducted in the Department of Conservative Dentistry and Endodontics, A. B. Shetty Memorial institute of Dental Sciences, Nitte University, Deralakatte, Mangaluru, Karnataka, India over a period of 1 month. Materials and Methods: The study included collection of thirty molars and preparation of class V restorations in each tooth. All the teeth were randomly divided into 3 groups Group I: Cavities left unrestored (Served as Positive control) Group II: Class V cavities restored with high strength glass ionomer (GC Fuji IX), Group III: Cavities restored with nano hybrid bulk fill composites (Tetric N ceram- bulk fill). After thermocycling, all the samples were placed in 2% methylene blue for 48 hours for cervical dye penetration test. All the samples were cut buccolingually using a diamond disk and dye leakage on cervical margin was measured under stereomicroscope at 20X magnification. All the results were subjected to statistical analysis. Results: The Kruskal Wallis test showed significant results for microleakage between groups. Fuji IX showed better sealing compared to Tetric N ceram- bulk fill. Control group exhibited highest microleakage. Mann Whitney U test of pair wise comparison between groups showed no significant microleakage between Fuji IX and Tetric N ceram group. Conclusion: Within the limitations of the present study, none of the materials were free from microleakage. Fuji IX Glass ionomer cements showed less dye penetration than Tetric N ceram.
