Abstract
The dental pulp may be exposed to several irritants that are potentially noxious to the health and
functions of this tissue. Each type of irritant or injury has different effects on the pulp, which are
generally characterized by acute inflammation, chronic inflammation or necrosis. Common examples
of irritants are dental caries, cavity preparation procedures, traumatic injuries, and chemical
substances like bleaching agents and adhesive systems. The present study aimed to review the
current knowledge about the effect of bleaching agents and adhesive systems in the human dental
pulp. The review covered literature from 2004 to 2009, and only relevant manuscripts were
included. Hand search of the references completed the review. Based on literature review, it may
be concluded that all dental procedures associated with bleaching agents or adhesive systems
involve risks to cause pulp damage. However, these risks can be minimized if the causal factors
were known and avoided.
