Morphological characteristics of primary enamel surfaces versus permanent enamel surfaces: SEM digital analysis.

The SEM images of primary teeth enamel show smooth enamel with little areas of irregularity. No linear structures are apparent. The SEM images of permanent enamel show a not perfectly smooth surface; there are furrows and irregularities of variable depth and width.

Also the thickness of primary teeth is almost 1/2 the size of adult teeth and the mineral composition is not that well developed as it takes only 2 years compared to
