![]() Absorbed doses were determined using thermoluminescent dosimeters on the skin surface of sensitive organs of an anthropomorphic phantom. With a small FOV, different areas were scanned (maxilla or mandible, anterior or posterior and TMJ). CBCT scans were obtained on OP300 Maxio unit varying scanning mode (standard, high and endo) as well as size (5 x 5, 6 x 8 and 8 x 15 cm) and positioning of FOV. In addition was compared the absorbed dose of two smaller FOV scans with that of a larger FOV scan for evaluation of temporomandibular joint (TMJ), as it is a bilateral structure. This study aimed to estimate the absorbed dose in cone beam computed tomography (CBCT) exams according to different exposure parameters and size and position of the field of view ( FOV).
