Invasive cervical resorption as a complication of intracoronal bleaching

Abstract

The article is devoted to invasive cervical resorption (ICR) as a complication of intracoronal bleaching. The purpose of the review: to analyze the available information on ICR according to domestic and foreign literature sources with the study of the mechanisms of the negative effect of dental materials for intracoronal bleaching on the dentin and cementum of the tooth root; processes of occurrence of ICR; properties that restorative products must have to combat this complication. In the course of the study, aggravating factors were identified, which are orthodontic treatment, trauma, dentoalveolar surgery, defects in the development of hard dental tissues. It has been determined that the mechanism of the negative effect of preparations for intracoronal bleaching on dentin and cementum of the tooth root is the process of free radical release. It was revealed that today, the mineral trioxide aggregate (MTA) is the only restorative material that suppresses osteoclastic activity, on the surface of which cementogenesis can occur.
