[Interpretation of the gingival inflammatory infiltrate].

The investigation of tooth eruption in dermoid cysts of the ovary allows one to observe in the chorion at the level of the epithelial attachment, an anatomical component that seems to correspond to a local system of defense. Up until now this has been considered to be a secondary inflammatory response resulting from the bacterial or mechanical assault. This component is found to form when the tooth erupts and constitutes an important element in the physico-pathogical process and of the immune response of the dental organ.
