The bisecting technique should be the operator's first choice when exposing periapical radiographs.

Select the correct answer(s).

Every precaution should be taken against retaking radiographs. Retake radiographs are not necessary when the first exposure results in errors that compromise image quality.

Select the correct answer(s).

(0/0)

Explanation

Retake radiographs ARE necessary when the first exposure results in errors.

Experts agree that a kilovoltage setting between 60 and 70 kVP produces quality radiographs while maintaining low radiation dosage; and a kilovotage setting above 90 kVp will unnecessarily increase patient dose and should not be used.

The collimator is a lead washer that increases the size of the x-ray beam; the filter is an aluminum disc that filters (removes) the long wavelength x-rays.

Select the correct answer(s).

(0/0)

Explanation

The collimator is a lead washer that RESTRICTS the size of the x-ray beam;

Consensus of radiobiologists is the dose received from a dental x-ray exposure is not likely to be harmful. Experts do not know what risk a small dose carries so it must be assumed that any dose carries a potential risk.
