A Comparative Analysis of Microleakage around Composite Restoration and Zirconium Ceramic Inlay under Confocal Microscope - An In Vitro Study
Journal Title: International Journal of Health Sciences and Research - Year 2017, Vol 7, Issue 6
Abstract
Aim & Objective: To detect and compare micro leakage of nano composites and zirconia restorations done on extracted teeth using nano composites and zirconium restorative material under confocal microscope. Materials and Methods: 20 caries free maxillary premolars were collected for the study. Class II - box only preparation was done on all extracted teeth out of which 10 teeth were restored using nano composite (ivoclar) and remaining 10 teeth were restored with zirconium ceramic material designed using CAD\CAM. All samples were subjected to thermocycling followed by immersion in Rhodamine-B dye solution for 48 hrs. The samples were sectioned in mesiodistal direction using minitom and dye penetration observed under a confocal laser electron microscope. The results were subjected to statistical analysis. Results: Group II Zirconia ceramic material shows lesser microleakage than group I nano composite. Conclusion: Based on this study it is advisable to use Zirconia ceramic Material for restorative purpose to minimise the micro leakage, further studies with greater sample size is a must to prove its accuracy.
