Early detection of external root cavities resorption is important because of the unpredictable and irreversible nature of these pathological processes. Our study assessed the sensitivity of the conventional radiography in an experimental model for diagnosing the radicular resorption cavities located in apical and medium radicular third. 150 artificial root resorption cavities were drilled, divided in four categories accordingly to diameter and depth. The conventional radiographs were examined with an X-ray viewing box with 2x magnification and the observers recorded presence and location of the artificial cavities. Conventional radiography can be used as a reliable exam for early detection of large root resorption cavities located
in apical and medium third (80.9%-91.6%). Dentists must be aware by the limits of conventional radiography in detection of medium root resorption cavities (52%-66%). Conventional radiography has higher sensitivity for root resorption cavities located on proximal root surfaces and lower sensitivity for root resorption cavities located on buccal root surfaces.
