Abstract

It is a well established fact that there is a fluid transport system through the dentin, however to the present time very little has been done regarding this system in teeth that have been endodontically treated.

The present work was conducted in vivo using the lower incisors of rats as the medium for the study.

A selected number of Sprague Dawley rats (36 animals), whose average age was 60 days, and whose body weight averaged about 180 grams, were given an anesthetic of Sodium Pentabarbitol, .05 to .07 ml. per 100 grams body weight. This anesthetic was injected intraperitoneally.

The tips of the incisors were removed and endodontic procedures performed, using Cavit as a filling material. Acriflavine HCl was then injected intraperitoneally and the animals were sacrificed at different intervals.

Immediately after sacrificing the animal, the lower jaws were frozen and sections were prepared. The sections were then observed and photographed under the Ultraviolet microscope.

It was observed that there was a greater fluorescence of the dentinal tubules bounded by the peridontal membrane, and there was a lack of fluorescence in the tubules bounded by the wall of the canal.
