The objective of this study was to compare the structure, morphology and enamel-composite and dentin-composite interface in the teeth of patients with chronic renal failure, predialysis and healthy patients, using two methods: atomic force microscopy (AFM) and scanning electron microscopy (SEM). Most of the tested enamel specimens showed a mixed type of failure. The AFM examination indicated a deep engraving for enamel and dentin in sick people compared to healthy people. The average value of the roughness (Ra) in enamel and dentin from healthy patients were significantly different (p <0.001) than from enamel and dentin in patients with renal failure. Regarding the SEM images, the dentin-composite material interface in teeth extracted from healthy patients, has uniformity, compared to the dentin-composite interface in teeth extracted from predialysis patients where a discontinuous hybrid layer with some gaps was identified.
Keywords: atomic force microscopy, scanning electron microscopy, enamel-composite interface, dentin-composite interface, predialysis
