OBJECTIVES Excessive heat produced during the curing of light-activated dental restorations may injure the dental pulp. The maximum temperature excursion at the pulp-dentin junction provides a means to assess the risk of thermal injury. In this investigation we develop and evaluate a model to simulate temperature increases during light-curing of dental restorations and use it to investigate the...
Polybutadiene acrylic acid acrylonitrile (PBAN) is binder for composite solid propellants used in spacecraft systems which its curing kinetics is so important. In this research, the effect of functionality of epoxy curative on the curing kinetics of PBAN is researched. Equivalent stoichiometric ratios of PBAN and di-functional (DER 331) and tri-functional (LY 5052) epoxy curatives was cured at ...
PURPOSE The aim was to evaluate the effect of curing mode and different dentin surface pretreatment on microtensile bond strength (µTBS) of self-adhesive resin cements. MATERIALS AND METHODS Thirty-six extracted human permanent molars were sectioned horizontally exposing flat dentin surface. The teeth were divided into 12 groups (3 teeth/group) according to the dentin surface pretreatment met...
