Effect of Resin Cement Thickness on the Push out Bond Strength of Fibre Reinforced Composite Post to Root Canal Dentine- An In-Vitro Evaluation.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 12
Abstract
Abstract: Thickness of the resin cement may vary in teeth restored with fibre reinforced composite post especially in situations with large root canal space. The objective of this study was to evaluate the influence of cement thickness on the bond strength of a fibre reinforced composite post system to the root canal dentine. Methods: Eighteen maxillary central incisors were decoronated. The canals were prepared and the specimens were randomly allocated to 2 groups. (n=9). Group A (low cement thickness) in which canals were enlarged to size 1 drill (1.2mm) and size I posts were cemented (1.2) and Group B were enlarged to Size 3 drill (1.5mm) and size 1 post was cemented (1.2). From each sample, 3 sections were taken (1.5 mm thickness). Cement thickness evaluation was done with Universal Measuring Microscope. Each specimen was tested for push out bond strength and data were statistically analyzed. Result: Bond strength of Group A and B did not show significant differences (P=0.5249). But the film thicknesses of these Groups were significantly different (P=0.00000). Conclusion: The increase in cement thickness did not significantly affect the bond strength.
