RESUMEN
<p><b>OBJECTIVE</b>To evaluate the value of cone beam CT (CBCT) in the treatment of jaw bone cyst.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>The CBCT images clearly demonstrated detailed information about the cyst, which was verified in the operation and helpful to the surgical preparation and treatment.</p><p><b>CONCLUSION</b>CBCT is more advantageous in the diagnosis and treatment of the jaw bone cyst than traditional panoramic radiography and periapical film.</p>
