Dental trauma classification is a system used to categorize and diagnose injuries to the hard dental tissue and pulp. It is an important tool for dentists to accurately assess and treat dental trauma. The classification system is divided into four categories: Class 1, Class 2, Class 3, and Class 4.
Class 1
involves a simple crown fracture with little or no dentin damage.Class 2
involves an extensive crown fracture that affects a significant amount of dentin but not the dental pulp.Class 3 involves an extensive crown fracture with dental pulp exposure.
Class 4
involves the loss of the entire crown, with signs of repair and part of the dental hard tissue interposed in the fracture line on the palatal side of the root. This classification system was developed by Andreasen and Andreasen in 199 and is known as the Traumatic Dental Injury (TDI) classification system. It is designed to be easy to use and understand, so that dentists can quickly diagnose and treat dental trauma.The TDI classification system is an important tool for dentists to accurately assess and treat dental trauma. It also helps to increase public awareness about the importance of proper diagnosis and management of dental trauma.
