Tooth resorption (TR):

Resorption of dental hard tissue

Internal resorption (RR:)

Tooth resorption originating within the pulp cavity

Stages of Tooth Resorption 

Stage 1 (TR 1):  Mild dental hard tissue loss (cementum or cementum and enamel). TR1
Stage 2 (TR 2): Moderate dental hard tissue loss (cementum or cementum and enamel with loss of dentin that does not extend to the pulp cavity). TR2 TR2 TR2 radiograph
Stage 3 (TR 3): Deep dental hard tissue loss (cementum or cementum and enamel with loss of dentin that extends to the pulp cavity); most of the tooth retains its integrity. TR3 TR3 clinicalTR3 radiograph
Stage 4 (TR 4): Extensive dental hard tissue loss (cementum or cementum and enamel with loss of dentin that extends to the pulp cavity); most of the tooth has lost its integrity.TR4a Crown and root are equally affected; TR4a TR4a radiograph
Stage 4 (TR 4): Extensive dental hard tissue loss (cementum or cementum and enamel with loss of dentin that extends to the pulp cavity); most of the tooth has lost its integrity.TR4b: Crown is more severely affected than the root; TR4b TR4b clinicalTR4b radiograph
Stage 4 (TR 4):: Extensive dental hard tissue loss (cementum or cementum and enamel with loss of dentin that extends to the pulp cavity); most of the tooth has lost its integrity.TR4c: Root is more severely affected than the crown. TR4c  TR4c radiograph
Stage 5 (TR 5): Remnants of dental hard tissue are visible only as irregular radiopacities, and gingival covering is complete. TR5 TR5 clinicalTR5 radiograph
