Root resorption-an overview

Root resorption is a naturally occurring phenomenon in primary dentition for the exfoliation of teeth. Root resorption in permanent teeth is a pathologic process that is not only specific to trauma or infections of pulp but also likely to occur due to untoward sequelae of any orthodontic procedures. There are internal and external types of root resorption, each having its variety. External apical root resorption is primarily asymptomatic, thereby mostly accidentally revealed by radiographic examination. Early diagnosis is essential to prevent, and manage the consequences, and to provide an optimal treatment option for the patient.
