DH103 Dental Radiology Quiz 3 Module 4 Latest Update Already Passed What is the primary purpose of the paralleling technique in dental radiography? To provide accurate and consistent images with minimal distortion How does the exposure time affect the radiographic image? Longer exposure times result in a darker image with more density, while shorter exposure times reduce the amount of radiation exposure What is the significance of the bisecting angle technique in dental radiology? It is used when it is difficult to use the paralleling technique, especially in patients with shallow palates or when there is limited space in the mouth What is the purpose of using an occlusal film in dental radiography? It is used to capture larger areas of the dental arch or for detecting pathology in the palate or floor of the mouth What is the most common type of radiograph used to detect dental caries? 2 Bitewing radiographs What is the primary difference between film-based and digital dental radiography? Digital radiography uses a sensor to capture the image electronically, while film-based radiography uses photographic film What does the term "focal spot" refer to in dental radiography? It is the small area on the anode target where electrons strike to produce X-rays What is the purpose of using a lead foil sheet in dental film packets? To reduce the amount of scatter radiation that reaches the film, improving image quality What is the effect of increasing the distance between the X-ray tube and the sensor on the radiograph? It reduces magnification and distortion, resulting in a more accurate image What is the main reason for using a high-speed film or digital sensor in dental radiography? To reduce the patient’s radiation exposure while maintaining image quality 3 What is the proper orientation of the dental X-ray film when placed in the patient's mouth? The identification dot should be placed toward the occlusal or incisal edge, with the film positioned parallel to the teeth What does the term "shadow casting" refer to in dental radiography? It refers to the principle that X-ray images should closely resemble the object being imaged, with minimal distortion or magnification What is the purpose of the fixer solution in film processing? To remove unexposed silver halide crystals and stop the development process, preserving the image What is the impact of improper exposure time on the radiographic image? It can lead to an underexposed or overexposed image, reducing its diagnostic value What is the role of the intensifying screen in film-based radiography? It helps convert X-rays into visible light, reducing the required exposure time for the film 4 What is the role of the X-ray tube in producing dental radiographs? It generates X-rays by accelerating electrons toward a target What is the function of the lead apron in dental radiography? To protect the patient from unnecessary radiation exposure What does the term "collimation" refer to in dental radiology? It is the process of restricting the X-ray beam to the area of interest to reduce scatter radiation
