Abstract 122 traumatized teeth with radiographic evidence of abnormal hard tissue formation in the pulp cavity were examined 10-23 years (mean 16 years) after the time of injury. Judged radiographically, partial obliteration (pulp chamber not discernible, root canal markedly narrowed but clearly visible) had occurred in 44 teeth (36\%). Normal periradicular conditions were found in all teeth with partial obliteration. Seventy-eight teeth (64\%) were recorded as totally obliterated. Pathologic periradicular changes indicating pulp necrosis as a sequel to the total obliteration was observed in 16 teeth (21\%). The late development of pulp necrosis was significantly related to teeth classified as severely injured, and to teeth with complete root formation at the time of injury. Furthermore, a comparatively rapid progress of the calcifying process appeared to be correlated with periradicular radiolucency.
