PRISMLESS ENAMEL IN HUMAN NON-ERUPTED DECIDUOUS MOLAR TEETH: A SCANNING ELECTRON MICROSCOPIC STUDY

The frequency, structure and thickness of the prismless enamel layer in the buccal and lingual surfaces of non-erupted deciduous molar teeth were described. The teeth were extracted, kept in a 70% ethanol solution, dried, coated with gold and examined in a scanning electron microscope JEOL, JSM-6.100. The aprismatic layer was observed in the occlusal, middle and cervical thirds of all buccal and lingual surfaces. The hydroxyapatite crystals were arranged parallel to each other and perpendicular to the enamel surface. No statistically significant differences were observed between the occlusal, middle and cervical thirds, which had 7.257 <FONT FACE="Symbol">m</FONT> m of average thickness.
