Case # 3: By: Dr. Robert Gottlieb and Suzanne Newkirk
Radiographic Resorption:
Perioscopic view of external root resorption #15.Suggested Etiology: Impacted 3rd molar The below case identifies external root resorption which extends into the cementum and dentinal structures.
Pre-op radiograph #15
The above pictures identify the resorption. The interior of the resorption is quite hard and may be Reparative dentin, which is formed as a reaction to external stimulation.
Treatment for this type of defect may vary depending upon the extent of the resorption.

Treatment of Root Resorption by Dr. John Y. Kwan
The below pictures define an area of root resorption that clinically and radiographically exhibited pocketing and bone loss. The attached video link shows a microsurgical repair of root resorption with Geristore; a radiopaque, hybrid ionomer composite used for subgingival restorations.
