ResumoSurface material removed with an excavator from 23 lesions diagnosed clinically as arrested dentine caries has been analysed by X-ray powder diffraction. While hydroxyapatite was present in all samples analysed, crystalline non-apatitic phases were detected in six of the samples. These were weddellite, whewellite, calcite, brushite, whitlockite and octocalcium phosphate. In only one sample, however, was a non-phosphatic phase, weddellite, predominant. In the remainder the non-apatitic phases were minor components although the results indicate that the distribution may be heterogeneous.
