title: Absorbed doses with intraoral radiography. Function of various technical parameters.
abstract: Both the maxillary incisor and mandibular molar regions of a Rando phantom were radiographed using specific technical parameters. The parotid gland and thyroid gland doses were measured using thermoluminescence dosimetry. Tube voltage, total filtration, mAs, collimation, and cone length were varied while keeping the other factors constant. Increased tube voltage or total filtration generally resulted in a slightly increased absorbed dose. Absorbed dose was decreased as the beam was more tightly collimated or the cone length was increased.
