CDCA Dental Hygiene (ADEX) - Additional Info Sample Questions

Size 1 film would most likely be used to radiograph the:

Correct Answer:
incisors and cuspids.

in dental radiography, different sizes of film are used to capture images of various sections of the mouth. the choice of film size is crucial as it impacts the clarity and coverage of the anatomical structures being examined. size 1 film is particularly suited for radiographing specific teeth in adults and older children, primarily because of its dimensions, which allow for detailed imaging of smaller groups of teeth.

size 1 film is commonly used to radiograph incisors and cuspids. these teeth, located at the front of the mouth, include the central incisors, lateral incisors, and cuspids (also known as canines). the size and shape of size 1 film make it ideal for capturing the detailed structure of these teeth, which are crucial for biting and cutting food. the film's narrower width compared to other sizes allows for easy placement in the limited space available in the anterior region of the mouth, minimizing patient discomfort.

it is important to note that while size 1 film is preferred for front teeth, other sizes are used for different parts of the mouth. for instance, size 0 film is generally used for children whose smaller mouth requires a smaller film for comfortable placement and effective coverage. for posterior teeth such as premolars and molars, larger films (such as size 2) are typically used because these teeth have more complex structures and require a larger area to be captured for a comprehensive evaluation.

in the case of a full mouth series, which often involves around 20 films in a typical adult dental examination, the use of size 1 film for the incisors and cuspids ensures that these critical teeth are imaged with sufficient detail and clarity. this is essential for diagnosing conditions such as cavities, alignment issues, and other dental problems that predominantly affect the front teeth.

hence, when considering the best use of size 1 film in dental radiography, it is most appropriately utilized for radiographing the incisors and cuspids. this targeted use allows for optimal imaging results, aiding in accurate diagnostics and effective treatment planning for dental health issues affecting these essential teeth.

Which dosimeter can only be reset after it has gone through an annealing process that wipes the device clean?

Correct Answer:
the optically stimulated luminescence dosimeter.

the optically stimulated luminescence (osl) dosimeter is a sophisticated device used for measuring radiation exposure. unlike other types of dosimeters, such as the film badge dosimeter, the osl dosimeter requires a specific process to reset its measurement capabilities. this process is known as annealing.

annealing involves heating the dosimeter to a high temperature and then cooling it down. this process is necessary because once the osl dosimeter has been read, it does not automatically reset itself. instead, the annealing process is required to clear the stored radiation information from the dosimeter's crystals, effectively wiping the device clean. this is crucial because it removes all previous radiation exposure data, ensuring that each new measurement period starts with a clean slate.

the necessity of the annealing process marks a significant difference between the osl dosimeter and other types, such as the direct reader dosimeter, which can be reset immediately after reading without any additional procedures. the unique feature of the osl dosimeter is its ability to store radiation information in a luminescent form, which is then stimulated optically for readings. this method provides accurate and sensitive measurements of radiation exposure but also necessitates the annealing process to reset the device.

after undergoing annealing, the osl dosimeters are reissued to employees or users for repeated usage. this capability to be reused multiple times not only makes osl dosimeters cost-effective but also environmentally friendly by reducing electronic waste. each cycle of use followed by annealing ensures that the dosimeter maintains its accuracy and reliability in monitoring radiation exposure over time.
