DEVELOPMENT OF THE HUMAN DENTAL LAMINA

Marlei Seccani, Lizeti Toledo Ramalho, Sebatião Hetem, Lourdes Santos-Pinto

Resumo


Dental lamina development was studied in 6–20 weeks of embryo and fetus lives. The upper and lower jaws were prepared in serial sections in both the sagittal and frontal planes. The hematoxylin-eosin staining sections were examined microscopically. It was observed that: (1) the first signs of dental lamina development appear at 11.5 weeks of intrauterine life; (2) the upper and lower first molar deciduous tooth germs are the first formed followed by the upper deciduous incisor; (3) the secondary dental lamina appears at 15.5 weeks for incisors and at 17 weeks of intrauterine life for canine and premolar tooth germs; and (4) the tertiary dental lamina appears at 15.5 weeks for upper molars and 18 weeks of intrauterine life for lower molar tooth germs.
