Selection Criteria For Radiography (SBA PAPER)

A patient comes to your dental office for a routine check-up. The patient is asymptomatic, has no history of dental problems, and is not experiencing any pain or discomfort. Which type of dental radiograph is most appropriate for this patient?

A) Panoramic radiograph B) Periapical radiograph C) Bitewing radiograph D) Occlusal radiograph

C) Bitewing radiograph.

According to Selection criteria for dental radiography, 3rd edition, bitewing radiographs are recommended for routine check-ups of asymptomatic patients with no history of dental problems or pain. They are also useful for detecting interproximal caries, which are not visible on a visual examination. Panoramic radiographs are used to view large areas of the mouth and jaws, while periapical radiographs are used to view individual teeth and surrounding structures. Occlusal radiographs are used to view the floor of the mouth and palate.

A patient presents with severe pain in their upper right molars. After examination, the dentist suspects an infection in the pulp of one of the molars. What type of dental radiography is the most appropriate for further assessment of this condition?

A) Panoramic radiography B) Bitewing radiography C) Occlusal radiography D) Periapical radiography

D) Periapical radiography

Periapical radiography is the most appropriate type of radiography for assessment of an infection in the pulp of a specific tooth. Panoramic radiography is not as detailed and may not provide enough information, bitewing radiography would be more appropriate for detecting interproximal caries, and occlusal radiography is not recommended for routine use in adults according to the Selection criteria for dental radiography, 3rd edition.

A 35-year-old patient presents to the dental clinic with a history of recurrent caries in the posterior teeth. The patient's last dental radiographs were taken 3 years ago. According to the Selection criteria for dental radiography, which of the following radiographs is recommended to assess for caries in the posterior teeth?

A) Vertical bitewing B) Panoramic radiograph C) Periapical radiograph D) Horizontal bitewing

D) Horizontal bitewing.

According to the Selection criteria for dental radiography, 3rd edition, the recommended radiograph to assess for caries in the posterior teeth is the horizontal bitewing. This is because it provides a view of the crowns and interproximal areas of the posterior teeth. Vertical bitewings are recommended for the assessment of interproximal caries in the anterior teeth. Panoramic radiographs and periapical radiographs are useful for evaluating other aspects of dental health but are not the recommended radiographs for assessing caries in the posterior teeth.

A dentist is reviewing a patient's case and is considering whether to order a dental radiograph. Which of the following principles should guide the dentist's decision-making process in accordance with Selection criteria for dental radiography?

A) Utilitarianism B) Deontology C) ALARP D) Virtue ethics

C) ALARP, which stands for "As Low As Reasonably Practicable." This principle emphasizes that the dose of radiation should be kept as low as possible while still obtaining the necessary diagnostic information.

A patient asks you about the amount of radiation exposure they receive on a yearly basis. According to the International Atomic Energy Agency, what is the average annual dose of radiation exposure in millisieverts (mSv) for a member of the general public in the UK?

A) 0.27 mSv B) 2.7 mSv C) 27 mSv D) 270 mSv

B) 2.7 mSv

The average annual dose of radiation exposure for a member of the general public in the UK is 2.7 mSv, which includes natural sources of radiation such as radon gas, cosmic radiation, and radiation from rocks and soil. This amount is considered safe and does not pose a significant risk to health.

A patient is concerned about radiation exposure. You settle this patient by using a banana as a reference for amount of radiation in comparison to a dental x-ray. What is the approximate amount of radiation in milliSieverts (mSv) that a banana contains?

A) 0.01 mSv B) 0.1 mSv C) 1 mSv D) 10 mSv

A) 0.01 mSv.

According to the Ionising Radiations Regulations 2017, what is the annual dose limit for radiation exposure for nuclear personnel in the UK?

A) 1 millisievert (mSv) B) 20 millisieverts (mSv) C) 50 millisieverts (mSv) D) 100 millisieverts (mSv)

B) 20msv
