Introduction: Dentin hypersensitivity is a pain arising from exposed dentin, typically in response to clinical, thermal, tactile, evaporative or osmotic stimuli that cannot be explained as arising from any other form of dental pathology. Most authorities agree that Brannstrom’s “Hydrodynamic Theory" of nerve stimulation due to movement of dentinal fluid, best explains dentin hypersensitivity. T...

BACKGROUND Bleached dental enamel can be more susceptible to staining than the enamel that has never been bleached, especially right after tooth bleaching. The aim of this study is to evaluate the effect of surface treatments and waiting time prior to contact with dye on bleached enamel staining susceptibility. MATERIAL AND METHODS One hundred teeth were bleached with 35% hydrogen peroxide (W...

Tooth bleaching is one of the most popular cosmetic dental procedures opted by patients who desire pleasing smile. It simplest, least invasive means available to lighten discolored vital teeth. A number desensitizing agents have been tried in an attempt counteract bleaching-related sensitivity. This study was done compare effect two different for controlling post operative sensitivity after pow...

Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), potassium nitrate, and sodium monofluorophosphate are desensitizing agents that help in reducing teeth sensitivity. However, indecisive evidence exists regarding their efficacy. Therefore, this study was conducted to compare the efficacy of casein nitrate with after in-office vital bleaching. A randomized controlled trial on 2011 pati...

A casein phosphopeptide (CPP) was prepared from beta-casein of cow's milk and the effect of this peptide on the absorption of calcium from a ligated segment of rat small intestine was investigated. CPP injected into a ligated loop of rat small intestine enhanced absorption of calcium from the loop and augmented the deposition of calcium in the femur. Furthermore, CPP inhibited the precipitation...
