Abstract

Effects of disinfectants, storage time and calcium hydroxide [Ca(OH)2] on tooth fracture strength were investigated. Part 1: 160 specimens were compression tested after various disinfection and storage regimes. Sodium hypochlorite significantly reduced loads at fracture followed by long-term distilled water. Other solutions had no effect. Fracture resistance was inversely proportional to storage duration and directly proportional to tooth size. Part 2: 100 incisors were impact tested after Ca(OH)2 medication. Mature teeth had significantly higher fracture resistance. Coronal access cavities significantly reduced fracture strength of immature but not mature teeth. Ca(OH)2 for 1 and 12 months did not affect tooth strength
