Week 7 (Chapter 12): Dental Images and the Dental Radiographer

Why is a clinical exam alone considered insufficient for a complete diagnosis?

It only allows the dentist to see the soft tissues and the teeth.

Which of the following is an example of 'Detection' that cannot be identified clinically?

Early bone loss around the root of a tooth due to periodontal disease.

What is the primary reason why the benefit of dental x-rays outweighs the risk?

Because they detect hidden problems that, if left untreated, would cause much greater harm and pain.

How do dental images help 'minimize and prevent' future surgical procedures?

By allowing for early detection of caries before they reach the pulp.

A patient like 'Emily' (CAL 3 mm) is hesitant to get vertical bitewings. What is the best clinical argument for the benefit of this image?

It allows us to monitor your bone levels and prevent further attachment loss through early intervention.

Which clinical principle ensures that we use the least amount of radiation possible to get a diagnostic image?

The ALARA principle

What's another name for extra teeth?

Supernumery teeth

If a patient's tooth was extracted years ago but they still feel pressure in that area, which radiographic finding might explain this?

A retained root fragment.

Why is a radiograph essential for a patient with supernumery teeth?

To see if the extra teeth are interfering with the roots of the permanent teeth.

Why is 'Quality Control' considered a patient protection responsibility?

Because it reduces the need for 'retakes,' thereby lowering total radiation exposure

Which task involves organizing processed x-rays into a frame or digital template according to their location in the mouth?

Mounting

Which goal is directly supported by avoiding 'retakes'?

Client Protection and Operator Efficiency

Why is 'meticulous processing' listed as a client protection measure?

Because poor processing leads to non-diagnostic images, which requires a retake.

Which of the following contributes the most to reducing patient radiation dose?

Using digital sensors or F-speed film instead of D-speed film.

What is the primary method of avoiding x-radiation as a dental radiographer?

Avoding priamry beam

If you are unable to leave the room during an exposure, where is the safest place to stand?

At an angle of 90 to 135 degrees to the primary beam.

Which of the following is considered a 'secondary change' due to trauma that would be identified on a dental image?

A fractured root that is not visible above the gumline.

Why is comparing 'follow-up' images with 'initial' images a critical part of the patient record?

To monitor the progression or healing of a condition, such as bone regeneration after periodontal therapy.
