Restoring a tooth with massive internal resorption to form and function: report of case

Article Abstract:

Preserving the function of teeth with internal resorption (pathological absorption and removal of the tooth material) is difficult, and the case study is presented of the efforts made in this regard on behalf of a young, healthy patient. In the absence of major trauma, but after a slight chip was made in the right upper first molar following the patient's biting on a strain gauge (to measure biting force), extensive resorption had taken place in the tooth. Endodontic treatment (treatment of the tooth pulp) was begun, but surgery was avoided because of the danger of perforating this fragile tooth. The nonsurgical approach is described; it consisted of inserting a temporary restoration, then removing it a week later and filling the tooth canals with gutta-percha (a latex material) and sealer. This was then removed and the tooth restored two weeks later by filling the pulp chamber (the resorbed area) with glass ionomer cement and amalgam (a material containing mercury) filings. The tooth was then filed and beveled to aesthetically pleasing proportions. At one year follow-up, the tooth was functioning well, with slight discoloration. Possible reasons for this excessive resorption are discussed. The unconventional approach used is recommended only for teeth with intact cusps (the points on the tooth's chewing surface), since worn cusps could hasten tooth perforation with subsequent wear and tear.

Forceps extraction of teeth with severe internal root resorption

Article Abstract:

It is possible to do a simple extraction of an upper tooth even if only a thin shell of the root remains. Normal extraction methods might crumble the root, and surgical techniques would remove much of the bone behind the lip needed for future restoration. The tooth is opened, internal decay removed, the interior etched with a 37% solution of phosphoric acid, washed out, primer and bonding agent inserted, and then a fast-setting composite material. After 10 minutes, the tooth can be extracted in one piece with forceps, leaving the bone behind the lip intact.
