This study considers X-ray power diffraction (XRD) applied to the study of mineral-based biomaterials used in odontostomatology. By means of this method the following materials were analysed: reabsorbable Dac Blu, non reabsorbable Dac Blu, non reabsorbable atomized Dac Blu, non reabsorbable fine Dac Blu, reabsorbable Biocoral 450, Calcitite 2040-12, Orthogel, Apagen, BTF 65, Calcitite 4060-2, Osprogel, Bio-oss, Biostite, Osprovit, Merck Hydroxyapatite. These analysis allow the identification of the crystalline phases, the study of the crystallinity and the crystal chemistry of the samples prepared as powder mixtures. This method permits the determination of the physical chemical and crystalline characteristics of these mineral based biomaterials formed by powders or transformable in powders. All of this information is indispensable for the evaluation of the functional biocompatibility of a biomaterial when its reaction in a biological environment is already known. This method has a great number of advantages against the traditional methods, marking with solid phases, it does not destroy the sample, it does not modify the physical or chemical characteristics and gives more information.
本研究考虑将X射线粉末衍射（XRD）应用于口腔医学中使用的矿物基生物材料的研究。通过该方法，对以下材料进行了分析：可吸收的Dac Blu、不可吸收的Dac Blu、不可吸收的雾化Dac Blu、不可吸收的细Dac Blu、可吸收的Biocoral 450、Calcitite 2040 - 12、Orthogel、Apagen、BTF 65、Calcitite 4060 - 2、Osprogel、Bio-oss、Biostite、Osprovit、默克羟基磷灰石。这些分析能够识别结晶相，研究作为粉末混合物制备的样品的结晶度和晶体化学。该方法可以确定这些由粉末形成或可转化为粉末的矿物基生物材料的物理化学和结晶特性。当已知生物材料在生物环境中的反应时，所有这些信息对于评估生物材料的功能生物相容性都是必不可少的。与传统方法相比，该方法具有许多优点，它以固相标记，不破坏样品，不改变物理或化学特性，并且能提供更多信息。
