SP-08 The New IADT/DTG Classification of Tooth Resorption and Associated Conditions
CE Hours: 1.5
Description: Numerous classification systems have been used in the dental literature over the years to describe the various types of tooth resorption. However, there has been no consensus and the dental profession has not adopted any particular classification for universal use. Compounding this problem has been the use of different, conflicting, confusing, unclear and inconsistent terminology to name the same condition which leads to uncertainty amongst clinicians, researchers and students regarding the diagnosis and management of resorbing teeth. The International Association for Dental Traumatology (IADT) and the Dental Trauma Guide (DTG) have recently collaborated to develop a new, comprehensive classification of tooth resorption and its associated conditions. During this session, this new classification will be presented with justification for the use of specific terminology. Each type of resorption will be defined and described to enable easy diagnosis. The general principles of management of each type of resorption will be outlined to provide clinicians with guidelines to manage their own cases. Examples showing the outcomes of these treatment protocols will also be presented.
Learning Objectives:
- Describe the principles used to develop the new IADT/DTG classifications of tooth resorption and associated conditions
- List the various types of tooth resorption and associated conditions as outlined in the new IADT classification
- Apply the new classification to clinical practice when diagnosing teeth with resorption
