Effects of bleaching agents and adhesive systems in dental pulp: a literature review

The dental pulp may be exposed to wide array of irritants that are noxious to the health and functions of this tissue. Irritants can be either short-term and longterm irritating agents or trauma. Each type of irritant or injury will have different effects on the pulp, which are characterized by acute inflammation, chronic inflammation or necrosis1. The pulp develops inflammation as a basic protective biologic defense mechanism in response to any type of injury. Common examples of irritants are dental caries, cavity preparation procedures, traumatic injuries, and chemical substances, like bleaching agents and adhesive systems.




The effect of chemical substances or restorative procedures on dentin and pulp is the result of a complex interaction among many factors such as, health of the underlying pulp, thickness and permeability of the intermediate dentin layer, mechanical injury during tooth preparation, toxicity of the restorative material and microleakage.
