Question 1

According to the American Academy of Oral and Maxillofacial Radiology, who may perform CBCT and implant imaging?

Accepted Answer

According to the American Academy of Oral and Maxillofacial Radiology, both a general dentist with adequate training or experience and a board-certified oral and maxillofacial radiologist may perform CBCT and implant imaging. However, it is important for the operator to have the necessary knowledge and skill to properly interpret the images and make appropriate clinical decisions based on the findings. A dental hygienist is not qualified to perform this type of imaging.

Question 2

Radiation is stopped and may not reach the receptor when it interacts with an area of high attenuation, such as:

Accepted Answer

Large amalgam restorations can absorb or scatter radiation, leading to reduced or blocked radiation reaching the receptor. Soft tissue and normal anatomic structures may also cause some degree of attenuation, but not as significant as large amalgam restorations. Periodontal abscess may enhance radiation transmission rather than attenuation due to the presence of air or gas.

Question 3

If the field of view is large, findings or pathology in other regions of the oral and maxillofacial complex may be accidently included. The size of the field of view should not matter if a high-quality machine is used.

Accepted Answer

The answer of If the field of view is large,...

Question 4

The specialty of oral and maxillofacial radiology was recognized in 1999 by the:

Accepted Answer

The specialty of oral and maxillofacial radiology was recognized by the American Dental Association (ADA) in 1999 through a resolution passed by their House of Delegates. This recognition allowed for the creation of specialized residency programs and board certification in this field, and it also helped to increase awareness of the importance of oral and maxillofacial radiology in dental practice.

Question 5

Metallic restorations may eliminate or hide the surrounding anatomy with the appearance of:

Accepted Answer

Metallic restorations can cause streak artifacts on radiographs, which can make it difficult to assess surrounding anatomy.

Question 6

Many dental professionals who incorporate CBCT into their practices have not had the training required to interpret anatomy beyond the maxilla and mandible. What steps can be taken to correct this deficiency that could potentially hinder the use of CBCT?

Accepted Answer

Incorporating CBCT into educational curricula and offering continuing education courses to dental professionals are both effective ways to correct the deficiency in interpreting CBCT beyond the maxilla and mandible. Hiring a trained interpreter may not always be feasible, and it is important for dental professionals to have the knowledge and skills to interpret CBCTs themselves. Therefore, choices a and c are the best options.
