Some preliminary observations on caries (“remineralization”) crystals in enamel and dentine by surface electron microscopy

摘要: The aim of this paper is to demonstrate a variety crystalline forms that occur in the enamel and dentine teeth with lesions undoubtedly due caries which are presumably result “remineralization” process. Two definite crystal types were found carious enamel; flattened rhombohedral (monoclinic) two large rhomboidal faces, prismatic hexagonal cross-section typically flat end-faces. Also on surfaces bodies strongly resembling bacterial faces apparent at their surfaces. In dentine, three different morphological inclusion tubule lumens addition both crystals usually described accumulation peritubular (intratubular) dentine. most abundant species as contaminant was identified β-tricalcium phosphate by X-ray diffraction, we presume correspond crystallites.
