Résumé
The objective of this study was to investigate bone mineral density (BMD) in the growing human mandible by dual-energy X-ray absorptiometry, comparing densitometric data with the nature of the dentition and hence, indirectly, with variation of mechanical stresses. Postero-anterior scans were performed on 58 dried mandibles (between 15 months and 14 years) by a Hologic QDR 1000 X-ray densitometer with "Ultra-Hi-Resolution" software (Hologic Inc., Waltham, MA). The analyses were performed on a polygonal area corresponding to the infero-median region of the mandibular body, and divided into three sections. The sample was divided into two groups according to the appearance of the first permanent molar. A high correlation is detectable between BMD values and age in the group with decidual dentition, while BMD values are significantly less correlated with age in the group with mixed dentition. There are no significant differences between the BMD values of males and females.
