A method for the preparation of circumpulpal dentine for lead analysis is described. The technique consists of cutting 6oo-,L-thin sections of deciduous teeth, and, utilizing a vice, fracturing off the circumpulpal dentine from the coronal dentine. Both dentine and circumpulpal dentine of teeth of normal American children and previously identified lead-poisoned children were prepared in this fa...

متن کاملAnalysis 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...

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 ...
