Principles and practice of operative dentistry . rocess of resorption, the result of a low inflammatorycondition, takes place in the walls of the bony crypt in which the crownof the tooth is lodged. This process is most active at the anterior or labialwall and the roof of the crypt, by which the upper portion of the sac andthe bony tissue are removed, as shown in Fig. 209, while the posterior orlingual wall remains unchanged, as it is required to form the labial wallof the crypt of the successional tooth. Prior to this, however, there isformed in the tissues immediately above the bony crypt of the follicle aninflammatory area in which resorption vacuoles are formed which gradu-ally increase in size. The opening made by this process (Fig. 210) finallybecomes larger than the diameter of the crown, thus giving it a roomyexit; but as soon as the crown has passed from the crypt and extrudedthrough the gum, the process of resorption gives place to that of a depositionof new osseous material, which loosely embraces the cervix of the tint; tooth of IkM-niouse, showing area of resorption.
