This case report describes a radiographical, histological and histochemical study of an extracted mandibular tooth with progressive external root resorption. The cells which appeared to be responsible for the hard tissue resorption showed an intense acid phosphatase activity, similar to that of bone‐resorbing cells. Some aspects on the etiology and pathogenesis of resorptive process that occurred in the present case are discussed.
