Deformities of the dentoalveolar ridge are usually the result of developmental defects, periodontal disease, trauma, or surgical insult. Various techniques are available to correct ridge defects. In this case presentation, ridge augmentation was achieved utilizing an acellular dermal matrix allograft in lieu of an autograft. This report demonstrated an acceptable esthetic result with a signific...

Taste buds consist of four kinds of cells which have distinct characteristics and play different roles in recognizing chemical compounds contained in foodstuffs. In this study we describe a procedure for separating viable taste bud cells from the fungiform papillae in mice. After sacrifice with CO(2), the mouse tongue was excised and immediately incubated in collagenase II and dispase II. The e...

In a previous paper (Tomaszewski, 1951) a survey was made of the side-effects of chloramphenicol and aureomycin treatment. These were divided into general, gastro-intestinal, genito-rectal, and oral manifestations. Changes in the oral cavity were found more frequently than in other parts of the body. They consisted of dryness of the mouth, throat manifestations, angular stomatitis, and changes ...

Tichy, F.: The Morphogenesis of CircumtJallate PapiUae and the Differentiation of Taste Buds in the Pig at 41 to 64 Days of Prenatal DefJe/opment. Acta vet. Bmo, 60, 1991: 99-1()()' Samples of tongues collected from porcine foetuses at 41, 44, 50, 53, 57 and ~ days after fc:rtilization were examined for the appearance and development of surface lingual structures. At each of the stages studied,...

Though 'lingual thyroid' has been an accepted term for many years, precise terminology might be served better by the use of ectopia to indicate those cases-the majority-in which no thyroid tissue exists in the orthotopic (prelaryngeal) site, the prefix lingual indicating the site of ectopia. Ectopia also serves to describe the situation in which a 'thyroglossal cyst' is solid and represents the...

For homeostasis, lingual taste papilla organs require regulation of epithelial cell survival and renewal, with sustained innervation and stromal interactions. To investigate a role for Hedgehog/GLI signaling in adult taste organs we used a panel of conditional mouse models to manipulate GLI activity within epithelial cells of the fungiform and circumvallate papillae. Hedgehog signaling suppress...
