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.

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 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 ...
