Examination of the roots of paramolar tubercles with computed tomography: report of 3 cases.

Computed tomography was used to examine root anatomy in 3 cases of paramolar tubercles. The images clearly showed the structure of the paramolar tubercles, including their root canal morphology. The root of the paramolar tubercle was united with the distobuccal root in each case. Canals were observed in all tubercles and were connected with the canals in distobuccal roots at various levels. In one case, the imaging information was helpful for endodontic treatment. The clinical importance of knowledge of the root and canal anatomy of these paramolar tubercles is discussed.
