There were slight variations among the Ca/P molar ratios found by EDS and XPS, suggesting differences in the mineral content from the enamel surface to the interior. 'Exposed prisms' was a secondary pattern. The enamel of sound deciduous teeth showed two main patterns: 'mostly smooth with some groves' and 'abundant microporosities'. The mean ratio between Ca bonded to phosphate and Ca bonded to hydroxyl was approximately 10:1. The crystallite size determined by XRD was 210.82 Â± 16.78 Ã…. The average Ca/P molar ratios were 1.37 and 1.03 by EDS and XPS, respectively. Three enamel patterns were observed by SEM: 'mostly smooth with some groves', 'abundant microporosities' and 'exposed prisms'. Chemical differences between incisors and canines were statistically evaluated using the Mann-Whitney U test (p â‰¤ 0.05).

The enamel of 30 human deciduous teeth was examined by: Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS), X-ray Powder Diffraction ( XRD), Fourier Transform Infrared Spectroscopy ( FTIR), and X-ray Photoelectron Spectroscopy ( XPS).

The purpose of this study was to characterise the enamel surface of sound deciduous teeth in terms of morphology, chemical composition, structure and crystalline phases. Zamudio-Ortega, C M Contreras-Bulnes, R Scougall-Vilchis, R J Morales-Luckie, R A Olea-MejÃa, O F RodrÃguez-Vilchis, L E
