Peripheral inflammatory root resorption. A review of the literature with case reports.

External resorptions associated with inflammation in marginal tissues are many times misdiagnosed and confused with caries and internal resorptions. A lack of uniformity in nomenclature has added to the confusion. This paper reviews the literature and presents cases to illustrate a rational approach to diagnosis and treatment. A new name is suggested to better reflect the features of this type of root resorption: peripheral inflammatory root resorption.
