In vitro effect of cavity disinfectants on the bond strength of dentin bonding systems.

Objective: To evaluate the effect of two cavity disinfectants, a 2% chlorhexidine and a 1% benzalkonium chloride solution, on the shear and tensile bond strengths of dentin bonding systems to dentin.

Method And Materials: Superficial dentin was exposed from 84 freshly extracted human third molars. The teeth were randomly assigned to two main groups according to the bonding agent used, either One Step or Optibond Solo.

An in vivo evaluation of hemorrhage control using sodium hypochlorite and direct capping with a one- or two-component adhesive system in exposed nonhuman primate pulps.

Objective: This study evaluated the biologic ability of sodium hypochlorite to control hemorrhage via chemical amputation of the coagulum, to remove dentin chips, to assist healing, and to facilitate formation of a dentinal bridge under two adhesive systems.

Method And Materials: Ninety Class V cavities with mechanical pulpal exposures were placed in the teeth of five adult monkeys and histologically observed. All exposures were prepared with a No.
