Article one delves into the complexities of external root resorption.

Root Resorption:
In their Abstract “Root resorption – diagnosis, classification and treatment choices based on stimulation factors”, Fuss, Tsesis and Lin stated “etiology of different types of root resorption requires two phases: mechanical or chemical injury to the protective tissues and stimulation by infection or pressure.”

The Abstract classifies various types of root resorptions according to their stimulation factors:

• Pulpal infection resorption
• Periodontal infection resorption
• Orthodontic pressure resorption
• Impacted tooth or tumor pressure resorption
• Ankylotic resorption

We have found that a history of trauma including excessive occlusal loading and idiopathic pathology are also factors in external root resorption.
