Experimentelle Untersuchungen zu De- und Remineralisationsprozessen im Wurzeldentin

Zusammenfassung

Um neue Kenntnisse zu Genese und Histopathologie, zur präventiven und therapeutischen Beeinflussbarkeit der Karies zu gewinnen, ist es notwendig, die initialkariösen Prozesse unter In-vitro-Bedingungen zu simulieren und den Einfluss verschiedener Faktoren auf die De- und Remineralisationsvorgänge aufzuzeigen. Die Erzeugung artifizieller kariöser Läsionen sowohl im Schmelz als auch im Dentin erfolgt dabei mit experimentellen Ansätzen und unterschiedlichen Aufgabenstellungen.

Summary

Fluoride application during artificial caries formation results in smaller lesions compared to the controls and a distinct remineralization within the lesions. There were no differences concerning this caries inhibiting effect between the toothpastes used (1400 ppm F- as SnF2/AmF, AmF or NaF). The cementum layer influenced the diffusion processes at the root surface. The combination of polarized light microscopy and X-ray microanalysis is a suitable model for studying de- and remineralization processes in bulk samples as well as in tooth sections.
