Abstract

This study examined the fluid movement in dentin associated with the exposure of the root surface for varying periods of time ranging from 75 minutes to 30 days. Eight kittens received experimental defects on the roots of the canines. Just prior to sacrifice a fluorescing dye was injected intraperitoneally to make the fluid within the dentin visible under ultraviolet light. Frozen ground sections were prepared and examined. The results showed that the exposed side of the root had a reduced amount of fluid fluorescence when compared to the opposite side of the tooth which had an intact root surface. The reduced fluorescence was evident from 2 to 14 days with a gradual recovery from 21 to 30 days. A discussion of the mechanisms of fluid movement and how the exposed root could alter fluid flow was presented. A possible correlation with root sensitivity in periodontal disease was also discussed.
