Abstract
High resolution TEM, X-ray diffraction analysis, infrared absorption spectroscopy, thermogravimetry, and chemical and electron microprobe analyses showed that in dentinogenesis imperfecta the mineral phase is a carbonated apatite with crystallites of normal size, but less numerous than in normal dentin. Losses of Ca, P, and Mg, and a higher Ca/P ratio and water content were recorded.
