RT1 - - REC with no loss of interproximal CAL - - Interproximal CEJ is not visible
RT2 - - REC with loss of interproximal CAL - - Interproximal loss of CAL is less than or equal to buccal CAL loss
RT3 - - REC with loss of interproximal CAL - - Interproximal loss of CAL is greater than loss of buccal CAL

Occlusal trauma and traumatic occlusal forces Traumatic occlusal force, which replaces the term “excessive occlusal force” of the previous (1999) classification, is any occlusal force that results in injury to teeth (such as excessive wear or fracture) and/or to the periodontal attachment apparatus. Occlusal trauma is a histological term to describe the injury of the periodontal attachment apparatus. The presence of traumatic occlusal forces and occlusal trauma may be indicated by one or more of the following: (a) fremitus (adaptive tooth mobility), (b) progressive tooth mobility, (c) thermal sensitivity, (d) excessive occlusal wear, (e) tooth migration, (f) discomfort/pain on chewing, (g) fractured teeth, (h) radiographically widened periodontal ligament space, (i) root resportion, (j) hypercementosis. It should be noted that some of the signs and symptoms of traumatic occlusal forces and occlusal trauma may also be associated with other conditions. Therefore, an appropriate differential analysis must be performed to rule out alternative aetiological factors.Traumatic occlusal forces lead to adaptive mobility in teeth with
