Management of invasive cervical resorption: observations from three private practices and a report of three cases.

Invasive cervical resorption (ICR) is a type of external resorption that is not well understood or well known in the dental community. It is often misdiagnosed, leading to improper treatment or unnecessary loss of the tooth. Treatment may involve the periodontium as well as the tooth and pulp, and management can be complex. Early diagnosis and appropriate treatment are the keys to a successful outcome. This article discusses the decision-making process and management of ICR, with emphasis on the restorative aspects of treatment. Three treatment cases are presented that include nonsurgical and surgical approaches, with recalls of 4, 8, and 9.5 years.
