Fracture resistance of endodontically treated maxillary central incisors with varying ferrule heights and configurations: In vitro study.

摘要: Objective: The objective of this study is to determine the best ferrule configuration endodontically treated teeth. Materials and Methods: A total 40 freshly extracted maxillary central incisors were collected. Teeth allocated into following four groups each having 10 Group 1 teeth restored with crowns (CRN), 2 (RCT CRN), 3 cast dowel cores incorporating uniform mm (2 FRL), 4 (1 FRL). Crown preparation was performed varying heights, cemented resin modified glass ionomer cement kept in 100% humidity for days, all specimens loaded failure a universal testing machine at 0.5 mm/min. Results obtained form kilo Newton Newton. Result: statistical analysis applied an variance detect presence group differences. Pair wise comparisons between analyzed Tukey Kramer significant difference test multiple comparisons. Conclusion: Ferrule had role fracture resistance custom post core Endodontically more resistant than those ferrule.
