Scanning Electron Microscopy of Root Resorption of Feline Teeth

Abstract

ABSTRACT. Scanning electron microscopy was carried out on 10 feline extracted permanent teeth from 3 cases with root resorption. Various-sized resorption lacunae were well defined, showing an etched pattern and configuration as shown in human deciduous teeth. In cats, regardless of the shape and depth of lacunae, the resorption lacunae showed opening dentinal tubules in the wall with or without cement matrix apperring only in the deep and round lacunae of human cases. Some specific process of mineralization for repairing dental root resorption was suggested in cats. KEY WORDS: feline tooth, root resorption, SEM.

Identifying early osteoclastic resorptive lesions in feline teeth: a model for understanding the origin of multiple idiopathic root resorption

“…The size of small focal lesions observed in this study (10–40 μm), which represents the site of attachment of a single osteoclast, were within the size range of focal lesions described in other scanning electron microscopy studies of feline osteoclastic resorptive lesions (20–40 μm) (32,33,44). Focal lesions were also within the size range reported in studies of deciduous tooth root resorption in the cat (20 μm) (45,46).…”
