Qualitative and quantitative phospholipid composition of porcine deciduous teeth pulp was studied by microthin-layer chromatography. Basing on the differences in the levels of individual phospholipids in the pulp of deciduous and permanent teeth, the authors come to a conclusion on the inadequate structural organization and functional activity of the pulp of deciduous teeth.

The electric characteristics were lowered or absent in 87 patients wearing removable metal-based dentures. The explanation is as follows: in patients with plastic plate dentures and permanent metal prostheses in the oral cavity the electric charges pass between the prostheses via the saliva and oral tissues; in patients with metal-based plate dentures the charges pass along the metal basis, which fact is due to high electric conductivity of metal. Therefore in patients with plastic removable dentures the electric charges have a more detrimental effect on the oral tissues.
