What is tuberculoma?
Tuberculosis may also involve the bone of the maxilla or mandible. One common mode of entry for the microorganisms is into an area of periapical inflammation by way of the blood stream; an anachoretic effect.
It is conceivable also that these microorganisms may enter the periapical tissues by direct immigration through the pulp chamber and root canal of a tooth with an open cavity. The lesion produced is essentially a tuberculous periapical granuloma or tuberculoma. These lesions were usually painful and sometimes involve a considerable amount of bone by relatively rapid extension.
