Invasive cervical Resorption
Invasive cervical resorption (cervical resorption) is a relatively uncommon form of external root resorption which has been a source of interest and academic debate by clinicians and researchers for over a century. Clinical, radiologic and pathological features of invasive cervical resorption province the basis for a clinical classification which is of use both in treatment planning and for comparative clinical research. Although the etiology of this condition remains obscure, knowledge of potential predisposing factors is important in assessing patients at risk. Treatment, where indicated, should aim at the inactivation of all resorting tissue and the reconstitution of the resorptive defect either by the placement of a suitable filing material or by the use of biological systems.
