In situ demineralisation of human enamel studied by synchrotron-based X-ray microtomography--a descriptive pilot-study.

摘要: An in situ study was designed to investigate naturally developed demineralisation human enamel a widely non-destructive manner combination with X-ray microtomography. Samples of were carried the oral cavity participants for 24 h daily either 21 or 29 days using so-called intraoral mandibular appliances (ICTs). Demineralisation thereby generated natural way without causing caries subjects' dentition. By employing synchrotron-based microtomography (XMT) volume image analysis, quantification and three-dimensional visualisation different stages mineral density loss possible. Basic features demineralised samples similar those reported earlier vitro studies. However, analysed showed significant differences morphology surface attack degree depending on carrier, exposure time position within ICT. In particular, varying local conditions carrier's seem be than an study. Our results show that ICTs quantitative analysis applied XMT data provides analytical tool which is highly suited fundamental investigation processes.
