Hard-tissue resorption and deposition after endodontic instrumentation.

Hard-tissue resorption and deposition following endodontic instrumentation were studied histologically in forty-one monkey teeth after 2, 7, and 42 days. No medicaments and no root canal filling materials were used. The number and length of lacunae and areas of resorption of the root canal wall, the root surface, and the lamina dura were counted and measured. Resorption, stimulated by instrumentation, was observed after 7 days at all sites. Resorption was slight at the root canal wall and at the root surface and was significantly more severe than normal osteoclastic replacement in the adjacent lamina dura. After 42 days the reaction had subsided at the three sites, but none of the tissue had returned to normal. Inflammatory reaction due to infection of the root canal appeared to enhance resorption after 42 days at the root canal wall and the lamina dura, but this was not observed at the root surface.

Crown and root resorption of a maxillary permanent first molar by an impacted second premolar: a case report.

A case is described of resorption of the mesial aspect of a maxillary permanent first molar in a 13-year-old boy whose maxillary second premolar was impacted. The premolar was partially erupted in the line of the arch and radiography revealed a radiolucent area involving enamel, dentine and cementum on the mesial aspect of the first molar. The first molar was extracted and the premolar erupted normally. The case emphasizes the importance of early diagnosis of developmental abnormalities.

An inhibitory principle in the matrix of periodontally diseased roots.

The inhibitory influence shown by the periodontally diseased root resides in its organic component. Its nature is uncertain and it may be an etiologic factor in periodontal destruction. The apatite structures of healthy and diseased roots are alike in being more receptive to the growth of bone and marrow than are their respective matrices.
