Dentine structure and mineralization in hypocalcified amelogenesis imperfecta: a quantitative X‐ray histochemical study

Abstract:

Objective:  This study was undertaken in order to establish the structural and mineralization pattern of the response of dentine to alterations in enamel in hypocalcified amelogenesis imperfecta (AI). Design:  The images and data obtained with scanning electron microscopy and electron probe X‐ray microanalysis in enamel and dentine specimens from control and affected teeth were compared in this study. Patients and methods:  We compared 46 fragments of permanent teeth from patients with clinically diagnosed hypocalcified AI and 20 normal permanent teeth. All specimens were prepared for electron probe X‐ray microanalysis. Results:  Dentine is characterized by thickening of the peritubular dentine and partial obliteration of the dentinal tubules that does not give rise to a compact sclerotic cast. In dentine, calcium levels were significantly higher in teeth with clinically hypocalcified AI in relation with control …
