[Comparative analysis of methods to stimulate and collect dentinal fluid: a clinical and experimental study].

Objective: The aim - to determine the most effective method of dentinal fluid collection and dentinal fluid flow rate stimulation.

Material And Methods: In a series of dentinal fluid collection tests, 3 types of filter membranes «Technofilter» were compared to a blotting nitrocellulose membrane Sartorius 1288. An ability of the studied membranes to adsorb dentinal fluid was assessed based on the data of proton magnetic resonance using signal magnitudes of the organic molecules accumulation in dentine fluid samples.
