DANB's Orthodontic Assisting Sample Test

The patient effective dose from bitewing x-rays is:





Correct Answer:
0.4 mrem


the correct patient effective dose from bitewing x-rays is 0.4 mrem. this value represents the amount of radiation exposure a patient receives from a typical dental x-ray procedure involving bitewing views. bitewing x-rays are commonly used to detect cavities between teeth and to assess the level of bone support around teeth.

it's important to understand that 0.4 mrem is a relatively low dose when compared to the overall radiation exposure that individuals receive annually from various sources. for perspective, the average annual radiation dose from all natural and man-made sources is estimated to be around 620 mrem in the united states. of this total, natural background radiation (from cosmic rays, radon, and terrestrial sources) contributes about 300 mrem per year.

in the context of dental x-rays, the use of modern digital x-ray technology and proper shielding techniques ensures that the radiation dose is kept minimal. the focus is always on adhering to the alara principle (as low as reasonably achievable), which aims to minimize radiation exposure while achieving the required diagnostic outcomes.

thus, when considering radiation safety in dentistry, it is helpful to note that the dose from a single set of bitewing x-rays (0.4 mrem) is a small fraction of the overall annual exposure to radiation from all sources. this emphasizes the safety and utility of dental x-rays as a diagnostic tool, contributing significantly to oral health care without exposing patients to undue risk.
