Effect of calcium hydroxide on the fracture resistance of dentin

Journal of Research of the National Institute of Standards and Technology, 2011
An increased incidence of fracture has been reported in teeth where root canals were treated with calcium hydroxide. Edge chipping is one test used to measure the resistance of brittle materials to fracture. Presently, no studies have reported on edge chipping in teeth.

Nanofibril-mediated fracture resistance of bone [PDF]

Bioinspiration & Biomimetics, 2021
Abstract Natural hard composites like human bone possess a combination of strength and toughness that exceeds that of their constituents and of many engineered composites. This augmentation is attributed to their complex hierarchical structure, spanning multiple length scales; in bone, characteristic dimensions range from nanoscale ...

Crack growth resistance in nuclear graphite [PDF]

, 2002
R-curve behaviour is often used for evaluating crack growth resistance in quasibrittle materials but few studies have focused on polycrystalline graphite. In this study, R-curve behaviour in three commercial grade nuclear graphites, of varying structure

Fracture Resistance of Ceramics: Edge Fracture Method [PDF]

Strength of Materials, 2005
Fracture resistance of macrohomogeneous linear elastic yttria, scandia, alumina, zirconia, and silicon nitride ceramics was studied upon flaking of the edges of rectangular specimens with the Rockwell indenter. The correlation between the obtained estimates and fracture toughness test results gained by the single-edge V-notched beam method was ...

Fracture resistance of veneers in premolars [PDF]

European Journal of Dentistry, 2018
ABSTRACT Objective: The purpose of the study was to compare the fracture resistance of ceramic veneers and composite resin veneers with and without dental preparation. Materials and Methods: Forty freshly extracted mandibular premolars were selected and randomly assigned into four groups (n = 10): Group NPR = no dental preparation and direct ...

Fracture Resistance of Reattached Hydrated Fragment of Fractured Incisors

International Journal of Clinical Pediatric Dentistry, 2020
Fragment reattachment procedure provides conservative treatment option when an intact fractured fragment is available. Rewetting of fractured fragment before reattaching has shown better bond strength of attached fragment. Therefore, fracture resistance of reattached fractured fragment with hydration and without hydration was evaluated and compared ...
