Correlations Between Morphology and Evolution in the Structure of the Tooth Germ

Sergiu Daniel S

The aim of this study was the microscopic morphologic assessment of the development of deciduous tooth germs to investigate whether it correlated with the biologic age. Methods: The study material consisted of oral tissue from 20 fetuses with a minimum gestational age of two months or newborns deceased at birth, cases autopsied in the Vaslui County Forensic Service and in the Pathology Laboratory of the Municipal Hospital Barlad, Romania. Legal harvesting, manipulation and conservation conditions were respected; the collection of the specimens was performed only after ethical approval and with the written consent of the family concerned. The investigation methods consisted of routine histological examination of the specimens after they had been processed through special decalcification techniques and stained with hematoxylin-eosin and three special stains. Results: The microscopic evaluation of deciduous tooth germs in cap and bell stage allowed the characterisation of the three main components
