Abstract:

Objective To evaluate the value of cone beam CT（CBCT） in the treatment of jaw bone cyst. Methods Twenty-five patients with jaw bone cyst were included, which were examined by CBCT as an addition of panoramic radiography. Through CBCT, the information about the three-dimensional location, the bone wall of cyst and the relationship between cyst, teeth and some other important anatomical structures were studied, surgical preparations and treatments followed accordingly. Results The CBCT images clearly demonstrated detailed information about the cyst, which was verified in the operation and helpful to the surgical preparation and treatment. Conclusion CBCT is more advantageous in the diagnosis and treatment of the jaw bone cyst than traditional panoramic radiography and periapical film.

Key words: cone beam CT, jaw bone cyst, surgical treatment
