      Abstract

      An unusual case of internal resorption has been reported. Extensive resorption of the dentine was seen rediographically and confirmed histologically. Histologic examination revealed bone replacement and almost total osseous metaplasia of the pulp. It appeared that the bone in the pulp chamber was sufficient to maintain the function of the tooth in the dental arch, even in the absence of continuity of dentine or cementum between crown and root.
      Both irregular lamellar bone and seemingly well-organized Haversian bone were found, as well as “osteoid” or “cementoid” which is usually described in cases of internal resorption. Quigley and Curtis16 have published illustrations which indicate that the vascular distribution of the pulp may resemble that of compact bone.
