Exploring the relationship between canines, sex and age: A CBCT analysis
Radiographic methods using PV and PTVR are important for dental age estimation. According to previous studies, these two markers possess different relationships with age in different sexes but none of the studies have used a homogenous (approximately equal numbers of individuals in each age range) …

CONE BEAM COMPUTED TOMOGRAPHY (CBCT) DOSIMETRY: MEASUREMENTS AND MONTE CARLO SIMULATIONS
<p>Cone beam computed tomography (CBCT) is a 3D x-ray imaging technique in which the x-ray beam is transmitted to an object with wide beam geometry producing a 2D image per projection. Due to its faster image acquisition time, wide coverage length per scan, and fewer motion artifacts, the CBCT …
