Expression of ameloblastin in the human tooth germ and ameloblastoma.
Oral Diseases, 2018OBJECTIVE To analyse the immunohistochemical expression of ameloblastin in the bell stage of tooth germ and compare with ameloblastoma to determine the level of differentiation of tumour cells.

Mucopolysaccharide histochemistry of rat tooth germs [PDF]
Histochemie, 1963 The histochemical distribution and localization of acid mucopolysaccharides and glycoproteins have been studied in rat tooth germs and lower joints. After fixation, sections were stained with PAS, alcian blue-PAS, colloidal iron, colloidal iron-PAS, colloidal iron-Feulgen, azure A and safranin O.

Advances in the identification of deciduous molar tooth germs
Legal Medicine, 2021In forensic anthropology, correct identification of human deciduous teeth is of paramount importance for age-at-death estimation and relies on detailed anatomical descriptions. Yet literature is scarce on indications: details on the morphology of molar tooth germs of fetuses and newborns, developing from multiple mineralized centers that will ...

Sonographic depiction of fetal tooth germs
Prenatal Diagnosis, 1995AbstractRecently, sonography of the fetal face has gained increasing importance in prenatal diagnosis. It is not yet clear whether sonographic depiction of fetal tooth germs would have an influence on the prenatal diagnosis of ectodermal dysplasia syndromes.

Dental Traumatology, 2019
BACKGROUND/AIM Dental trauma is a common emergency in children with primary teeth. The aim of this study was to determine stress propagation to the permanent tooth germ and surrounding bone and soft tissues during dental trauma to primary central ...

Acidic glycosaminoglucuronoglycans of human tooth germs
European Journal of Oral Sciences, 1973abstract – The acidic glycosaminoglucuronoglycans in germs of primary teeth from three human fetuses have been isolated and identified. The biochemical analysis revealed the presence of hyaluronic acid and chondroitin‐4‐suIfate and/or chondroitin‐6‐sulfate while dermatan sulfate and heparan sulfate were not demonstrated.

Artificial Organs, 2016
The purpose of this study was to demonstrate the feasibility of whole-tooth regeneration using a tooth germ-like construct. Dental pulp from upper incisors, canines, premolars, and molars were extracted from sexually mature miniature pigs.

Fascin in tooth germs: an immunohistochemical analysis
Journal of Histotechnology, 2018Development of a tooth is a complex process that involves three stages namely bud, cap andbell which results from the interaction of cells of the oral mucosa and neural crest. During this process, oral and neural crest cells undergo various changes resulting in proliferation, apoptosis,morphological, and cyto-differentiation, which in turn would have ...

Fluorine determination in hamster tooth germs
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1988The delayed 52+ → 12+ nuclear transition of fluorine (Eγ = 197 keV, t12 = 87 ns) emitted after the 19F(p,p′ γ)19F reaction, has been used to measure the influence of fluoride administration on tooth development in vivo. The method used has the advantage of an improved peak to background ratio for the detection of fluorine if measurements are performed ...

The effect of thymectomy on tooth-germ allografts in rats
Archives of Oral Biology, 1971Abstract The development of the lymphoid tissues is dependent on the presence of a normal thymus gland. The removal of the thymus in 24-hr old rats produces a dramatic suppression of immunological activity in lymphoid tissues. When tooth germs were allogenically transplanted to 2-week-old rats totally thymectomized at birth, the transplants grew ...
