In vitro studies with X-ray diffraction

Dobrinka Mitkova Damyanova


Introduction: Different teeth and tooth surfaces with a variable risk of developing caries. Fully developed enamel consists of hydroxylapatite carbonate (KHA) (92-93% by weight of the temporary teeth) and less than 1-2% by weight of organic substances. Enamel no cells and therefore can not be biologically restored. Objective: The purpose of the study is an analysis of the coating deposited on the enamel of deciduous teeth.

Methods: The hotel is on temporary teeth enamel which is coated with lacquer mineralization Clinpro™ White Varnish with TCP (Tri-Calcium phosphate) (3M). The study is done in‚ High-tech laboratory for specialized X-ray and tomography methods „of an apparatus for X-ray system PANalytical Empyrean. Results: Measurements of the near-surface thin film experiment shows shift peak at larger angles corresponding to available fluorapatite. Analysis of the coating: Fluorapatite (Fluor Apatite, Apatite- (CaF)) of the formula Ca5 [F | (PO4) 3].

Conclusions: There is formation of the coating due to the diffusion of ions of the lacquer to the surface of the enamel of the tooth. Cover is constructed mainly of fluorapatite. In the depth of enamel gradually becomes predominant phase hydroxyapatite. Analysis of the core shows that the tooth is composed of hydroxyapatite and calcium.
