Demystifying Tooth Resorption

Resorption is a condition associated with either a physiologic or a pathologic process resulting in loss of dentin, cementum and/or bone. Physiologic resorption is seen in primary teeth that results in their exfoliation and allows eruption of their permanent successors. Pathologic resorption can occur following traumatic injuries, orthodontic tooth movement, or chronic infections of the pulp or periodontal structures and if untreated results in the premature loss of the affected teeth. Early detection and correct diagnosis of tooth resorption is essential for successful management and favorable outcomes. Also, appropriate therapy increases the chances of maintaining the tooth in the mouth, which is particularly important in the esthetic zone of the patient. Delay in treatment via late diagnosis and referral waiting times may be catastrophic. Therefore, timely intervention is essential for optimum management.
