14h00 Rapid differential diagnosis of dentomaxillary pathologies by use of CBCT

We propose different diagnostical steps regarding the majority and the most frequent dentomaxillary lesions. The first step is lesional description, the second precise lesional topography, the third discuss a sex predominance and age of diagnosis, and the fourth is a discussion about specificity of semiological signs. The CBCT with its possibilities of three-dimensional and multiplanar reconstructions, with its higher resolution than a CT, allows more accurate differential diagnosis of dentomaxillary pathologies. Diagnosis is always oriented by the clinic aided by CBCT, more rarely by CT or MRI and finally often completed by histological analysis especially in tumoral pathologies.
