General and dental pathology with special reference to etiology and pathologic anatomy; a treatise for students and practitioners . Vie 40—A longitudinal section of a normal pulp of man. a. a. a. a odontoblasticlayer- & nerve trunk; c, c, plexus of nerves under odontoblastic layer.

The odontoblasticlayer of the pulp is the only connective tissue in the bodyhaving cells of columnar form. This columnar form does not,however, persist throughout the life of the pulp. It is particu-larly evident prior to and during the formation of dentin; butin old pulps, i. e., after dentin has been formed, the odontoblastsare round or oval. They are the specific dentin-produeingcells—a function which they retain throughout the life of thepulp. They send processes into the tubules of the dentin—the.

The same structural elements are to befound as are indicated in the previous section. dentinal fibrillar or fibers of Tomes, and probably are connectedamong themselves by delicate fibrous processes. Layer of Weil.—The layer of Weil is supposed to be that por-tion of the pulp lying between the odontoblastic layer on theoutside, and the portion of the pulp which is thickly studdedwith connective-tissue cells distributed throughout the gelati-nous matrix of the pulp on the inside. It itself is described asbeing very sparingly embedded with connective-tissue cells. Innumerous specimens this layer does not exist, but whether pres- THE DENTAL ITU AND ITS DISEASES 503 ciil or not, is of qo physiologic import. Von Ebner has attributedthe layer of Weil to shrinkage of the body of the pulp, whileWahlkoflE considers thai the phenomenon is cau
