Analysis of lead in circumpulpal dentin of deciduous teeth.
Absorbed lead continuously adds to the lead deposited in the vascularized circumpulpal dentin of the teeth. Thus, this dental tissue is expected to contain a lead concentration which reflects the integrated lead exposure during the time from completion of tooth formation to tooth extraction or shedding. A method has been developed to assess the lead level in the dentin surrounding the pulp cham...
متن کاملStructure and microstructure of coronary dentin in non-erupted human deciduous incisor teeth.
The dentin structure of non-erupted human deciduous mandibular and maxillary central and lateral incisor teeth was studied employing light and scanning electron microscopy. For light microscopy, nitric-acid-demineralized and ground sections were used. The sections were stained by hematoxylin-eosin, picrosirius and azo-carmine methods, and ground specimens were prepared using a carborundum disk ...
متن کاملMorphological Alterations of the Surfaces of Enamel and Dentin of Deciduous Teeth Irradiated with Nd:YAG, CO
Several studies have shown the possible applications of different types of lasers in dentistry clinics, as for example, in the inhibition of carious lesions (Stern et al., 1966, 1972; Yamada, 1996), as well as in their removal (White et al., 1993), in the oral mucous (Taylor et al., 1965), and in gum healing (Chomette et al., 1987), among others. The scanning electron microscope has shown the d...
متن کاملOrthodontic movement in deciduous teeth
Deciduous teeth exfoliate as a result of apoptosis induced by cementoblasts, a process that reveals the mineralized portion of the root while attracting clasts. Root resorption in deciduous teeth is slow due to lack of mediators necessary to speed it up; however, it accelerates and spreads in one single direction whenever a permanent tooth pericoronal follicle, rich in epithelial growth factor ...
متن کاملDentin dysplasia type I—novel findings in deciduous and permanent teeth
BACKGROUND Dentin dysplasia type I (DD-I) is a rare autosomal dominant hereditary disorder which seriously affects the root development of teeth, causing spontaneous tooth loss (in teenagers). At present, the study of DD-I focuses on familial and phenotypic analyses and reports regarding the ultrastructural study of DD-I are few. The purpose of this study was to clarify and discuss the clinical...
