Iatrogenic root resorption of upper first permanent molars associated with orthodontic treatment. Report of a case. 1987

F J Hill

A case of severe resorption of the roots of upper first molars, associated with second molar impaction, is reported. The possible causes of this condition, which occurred as a complication of rapid maxillary expansion and distal movement of the first molars, are discussed.
