Abstract
This study was pemformed to evaluate the influence of 6 different solutions to the reattachment on the experimentally exposed Cementum in male rats. A rubber strip was threaded in the distal part of the mandibular first molar. Then, at the removal of the rubber after two days, 6 solutions were applied to the exposed root surface by a needle. Six solutions were composed of (1) Blood, (2) Collagenase, (3) Lipopolysaccharide, (4) Whole Saliva, (5) Calcium-chloride and (6) E.D.T.A.. Those mandibulars were resected for histological evaluations after one week from the application. The results were as follows.
1) Control specimens not applied any solutions showed reattachment without denudation of the root surface, however existing long junctional epithelium which was not seen in normal rats.
2) In the experimental groups of (1), (2), (5) and (6), any particular differences were shown, compared with the control specimans.
3) In groups (3) and (4), some of them showed a slight but distinct denudation of the root surface.
