Periapical x-rays are used to capture images of a specific area of the mouth, such as a single tooth and its surrounding structures. This type of x-ray requires a small film size to focus on the targeted area and limit exposure to other areas of the mouth. Option A, '0', would be too small to capture the desired image, while option B, 'Orthodontics', is larger and used for full-mouth scans. Option C, 'Interproximal/BWX', is also a larger film size typically used for capturing images of multiple adjacent teeth. Therefore, option D is the best choice for adult Periapical x-rays as it is the ideal size for isolating the specific area of interest.
