Abstract

The Parthenocissus Tricuspidata, genus of the Vitaceae family, is a rustic plant with lianas, whose tendrils tips have organelles called adhesive discs that, set near a substrate, adhere to it.

Studies of A.G. ENDRESS, W. THOMSON, S. JUNKER attribue the disc adhesion ability to an adhesive substance secretion instead of a suction mechanism.

Teeth were set beneath the tendrils and in few weeks the adhesion to enamel, dentin and radicular cement was so strong as the usual adhesion to the wall, except with teeth that were set before in fluoride gel, because of the element cytotoxicity.

Then the adhesion place was investigated with microanalysis and S.E.M.

The microanalysis has shown calcium and phosphorus both on enamel and on adhesion place, while silicon, sulphur, chlorine and potassium were only on the adherent vegetable substance.

The S.E.M. analysis was conducted on the enamel surface, after removing of the vegetable, and perpendicularly to the adhesion surface of the vegetable with the enamel, the dentin and the cementum.
