A Scanning Electron Microscopic Study of Hypercementosis
The purpose of this study was to evaluate morphological characteristics of teeth with hypercementosis that are relevant to endodontic practice. Twenty-eight extracted teeth with hypercementosis had their root apexes analyzed by scanning electron microscopy (SEM). The teeth were divided according to tooth groups and type of hypercementosis. The following aspects were examined under SEM: the cont...
متن کاملTongue structure in the long-eared hedgehog (Hemiechinus auritus): A scanning electron microscopic study
The aim of this study was to investigate the dorsal surface of the long-eared hedgehog tongue using scanning electron microscopy. The tongue of the long-eared hedgehog is rectangular-shaped with an elongated body and a widened root and a marked deep median groove can be seen on its dorsal surface. A characteristic feature of the lingual root is presence of two huge laterally situated folds. The...
متن کاملLight and scanning electron microscopic study of the lingual structure in the budgerigar (Melopsittacus undulatus)
BACKGROUND: The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. OBJECTIVES: The aim of the present investigation was to investigate lingual structure in adult budgerigar. METHODS: Tongues of 12 adult budgerigars were used ...

متن کاملMorphogenesis of human bronchial diverticulum. A scanning electron microscopic study.
Diverticulosis of the bronchial wall was found in patients not only with, but also without, chronic obstructive lung disease; it appeared to start as submicroscopic depressions and dilatations of the ducts of the bronchial gland on the mucosal surface. Multiple depressions and dilatations fused to form a diverticulum which herniated between and through the smooth-muscle cellular bundles. Ruptur...
