Submit
8. Bitewing radiographs are also known as interproximal radiographs

Explanation

Bitewing radiographs are commonly used in dentistry to capture images of the crowns of the upper and lower teeth. These radiographs are called "bitewings" because the patient bites down on a small tab or wing-shaped device that holds the film or sensor in place. The purpose of bitewing radiographs is to detect dental caries (cavities) and monitor the health of the interproximal areas, which are the spaces between the teeth. Therefore, it is correct to say that bitewing radiographs are also known as interproximal radiographs.

Submit
9. The paralleling technique is used a film-holding device

Explanation

The statement is true because the paralleling technique is indeed used as a film-holding device. This technique involves aligning the X-ray beam perpendicular to the film or image receptor, ensuring that the X-rays pass through the patient's body parallel to each other. This helps in reducing distortion and producing accurate and clear images. By using the paralleling technique, the film or image receptor is securely held in place, allowing for precise positioning and minimizing the risk of movement or blurring during the X-ray procedure.

Submit
10. Radiation exposure times are the same for children as for adults

Explanation

The statement is false because children are generally more sensitive to radiation than adults. Their developing bodies and organs are more susceptible to the harmful effects of radiation.

Submit
15. The fundamental principle of panoramic radiography is based on the pronciple of tomography

Explanation

Panoramic radiography is a dental imaging technique that captures a wide-angle view of the entire oral cavity, including the teeth, jaws, and surrounding structures. It is based on the principle of tomography, which involves capturing images of specific layers or sections of the body while blurring out other areas. In panoramic radiography, the x-ray tube and film/detector rotate around the patient's head, capturing images at different angles. These images are then combined to create a single panoramic image. Therefore, the statement that the fundamental principle of panoramic radiography is based on the principle of tomography is true.

Submit
16. The cervical collar on the lead apron protects the reproductive organs 

Explanation

The statement is false because the cervical collar on the lead apron is designed to protect the neck and cervical spine, not the reproductive organs. The lead apron itself is used to shield the reproductive organs from radiation exposure.

Submit
17. What detemines the quality of radiation 

Explanation

The quality of radiation is determined by kilovoltage. Kilovoltage refers to the amount of energy that is applied to the x-ray tube, which in turn affects the penetration and quality of the radiation produced. Higher kilovoltage results in higher energy x-rays that can penetrate deeper into the patient's body, resulting in better image quality. Milliamperage, on the other hand, determines the quantity or amount of radiation produced, but does not affect the quality. Therefore, kilovoltage is the key factor in determining the quality of radiation.

Submit
18. Another name for the lead diaphragm is the 

Explanation

The lead diaphragm is commonly known as a collimator. A collimator is a device used to narrow down or restrict the size of a beam of particles or waves. In the context of radiology, a collimator is used to shape and limit the X-ray beam, ensuring that only the desired area is exposed to radiation. The lead diaphragm within the collimator helps to block and shape the X-ray beam, reducing scatter and improving image quality. Therefore, collimator is the correct term for the lead diaphragm in this case.

Submit
19. Using E -speed film instead of D-speed film will reduce the developing time

Explanation

Using E-speed film instead of D-speed film will not reduce the developing time. The speed of the film refers to its sensitivity to light, with E-speed being less sensitive than D-speed film. However, the developing time is determined by the chemical process required to develop the film, and it is not affected by the film's speed. Therefore, the statement is false.

Submit
20. What determines the amount or quantity of radation

Explanation

Milliamperage determines the amount or quantity of radiation. Milliamperage refers to the current or flow of electrons through the X-ray tube. Increasing the milliamperage will result in a higher quantity of radiation being produced, while decreasing the milliamperage will reduce the amount of radiation. The milliamperage setting is an important factor in controlling the exposure and ensuring appropriate radiation dose for the patient.

Submit
21. The area on the tungsten target where the electron hit is the 

Explanation

The focal spot refers to the area on the tungsten target where the electron hit. When electrons strike the target, they create X-rays that are emitted from a small region known as the focal spot. This spot is crucial in determining the resolution and clarity of the resulting X-ray image. A smaller focal spot size leads to a sharper image with better detail, while a larger focal spot size may result in a blurrier image with reduced detail.

Submit
22. The storage phosphor imagin is anoth type of direct digital imaging system

Explanation

The given statement is incorrect. The storage phosphor imaging is not another type of direct digital imaging system. It is a type of computed radiography (CR) system that uses a storage phosphor plate to capture and store X-ray images. These images are then read and converted into digital format using a laser scanner. Direct digital imaging systems, on the other hand, use digital detectors such as amorphous selenium or amorphous silicon to directly capture and convert X-ray images into digital format without the need for a separate storage medium. Hence, the correct answer is False.

26. THE _____ IS ONE OF THE MOST WIDELY USED IMAGE RECEPTORS IN DENTAL DIGITAL RADIOLOGY 

Explanation

CCD stands for Charge-Coupled Device, which is a type of image receptor commonly used in dental digital radiology. It is widely used due to its high resolution and sensitivity to light, making it suitable for capturing detailed dental images. PID, on the other hand, stands for Position Indicating Device, which is not an image receptor but a component used to align the X-ray beam. Therefore, the correct answer is CCD.

Submit
27. When the xrays strike the film, the information is recorded on the film.  This is called digital imaging.

Explanation

The given statement is false because when x-rays strike the film, the information is not recorded digitally. Instead, the x-rays create a latent image on the film, which is then developed using chemicals to create a visible image. This process is known as traditional or analog imaging, not digital imaging.

Submit
28. Labial mounting is when the depressed dot is toward the operator as if the operator is viewing the films from inside out.

Explanation

Labial mounting is when the depressed dot is away from the operator, as if the operator is viewing the films from outside in. Therefore, the correct answer is False.
