The majority of studies confirming the safety of bleaching systems are contrasted with a few investigations that have shown surface degradative changes associated with bleaching processes. (2005) stored their samples between bleaching sessions in distilled water. In the case of three studies which showed no effect of bleaching products on enamel surface morphology, (Duschner et al. abstract 2004) human whole saliva was used as a key part of replicating the in vivo situation. Surface microhardness (SMH) measurement has been a frequently used technique for evaluating the effects of peroxide and bleaching products on enamel and dentine.

A 10% carbamide peroxide bleaching agent was evaluated against a placebo agent. Several studies have examined the effects of vital bleaching on pulp histology. Specimens were randomly assigned to seven groups using different bleaching agents as well as a placebo agent.

The authors conclude that bleaching treatment may result in increased tooth brushing abrasion. It is well established that a common adverse effect of vital tooth bleaching is dentinal hypersensitivity. (2006) studied how tooth bleaching abrasive dentifrices might change the outer superficial enamel Human enamel Whitening dark skin creams for Congolese men slabs were exposed in vitro to a 10% carbamide peroxide bleaching agent at different times and submitted to different superficial cleaning treatments.
