RESUMO
Resulting from phase-analytical and chemical examinations there are characteristically habitual differences in the consistency of dental calculus. Very obvious are sex (gender) specific and job specific differences concerning the contents of heavy metals like lead, cadmium, copper, and zinc. Characteristics concerning the quantity, consistency and temper of dental calculus as well as the peal-homogeneous value (pH-value) of the saliva are obvious with miners working in salt-mines.

The efficiency of extremely small particles of hydroxylapatite on a therapy with hypersensitive tooth-necks was approved in a double-blind-study. 90% of the test persons stated an improvement of their complaints after 3-5 days, and 50% became complaintless within the time of study. The manner of working was proved with the help of x-ray inclination and by polarisation-optical studies.

The operative procedure for partially replacing the root with A12O3 ceramic represents a good possibility for preserving teeth in which the pulpa is devitalized. The method used in connection with the well known autoplastic reimplantation not only presents an alternative to the traditional apicoectomy but also provides additional stabilization of the tooth by lengthing the root with cocotostabile and biocompatible A1203 ceramic. The method was tested in humans and monkeys. Argumentation was based on histological examination via light microscopy.
