["Push-pull" perfusion technic, a new approach applied to the study of transdentinal fluid].
The flux through the dentin tubuli is at the origin of the hydrodynamic theory of tooth sensitivity. After a review of the various in vivo techniques reported in the literature, this study describes an original method of dentin perfusion--so called "push-pull" and specific to this topic. With this technique, the authors have demonstrated the kinetics of this flux, as well as the effect of some factors (age, colchicine, ouabain), on transdentinal fluid exchanges. The analysis of all these results suggests that a combination of active and passive movements could be at the origin of this flux, the temporary inhibition of which could present major advantages in current Periodontics practice.
