摘要

摘要采用正则化求解的序列展开方法，对牙釉质进行了定量纹理研究，构建并分析了由直接极值图重建的取向分布函数。研究发现，健康牙釉质由化学式为 Ca10(PO4)6((CO3)0.75(OH)0.5)的羟基磷灰石形成，具有相当锐利的基底纹理。在牙釉质破坏过程中，羟基磷灰石的质地会发生变化，变得更加分散。

Quantitative Texture Study of the Tooth Enamel

Abstract

A quantitative texture study of the tooth enamel, with construction and analysis of the orientation distribution function reconstructed from direct pole figures, has been performed by the series expansion method with regularization of solutions. It is found that the healthy tooth enamel is formed by hydroxyapatite with the chemical formula Ca₁₀(PO₄)₆((CO₃)_0.75(OH)_0.5), which has a fairly sharp basal texture. During the enamel destruction the hydroxyapatite texture changes, becoming more diffuse.
