TUBERCULOSIS AND PERIODONTAL DISEASE, WITH SPECIAL REFERENCE TO THE COLLAGEN FIBERS

¹ University of Michigan School of Dentistry, Department of Oral Pathology and Periodontia, Ann Arbor, Mich.

1. No periodontal changes were observed that could be attributed to tuberculosis in 10 rhesus monkeys.

2. No indication of collagen changes was noted in sections from jaws and joints.

3. No observations substantiated the theory of lowered periodontal resistance in tuberculosis.

4. Any increase in incidence of periodontal disease associated with tuberculosis must be produced by local factors of which poor oral hygiene appears to be the most significant.

5. Traumatic periodontal changes resembling diffuse atrophy or periodontosis were observed both in the experimental and in the control animals.
