How many films typically comprise an adult full mouth series?

18 to 20
10 to 15
20 to 25
8 to 10

The correct answer is: 18 to 20

An adult full mouth series usually consists of 18 to 20 films. This series typically includes a variety of periapical and bitewing radiographs, which are essential for obtaining a comprehensive view of all the teeth and surrounding structures in the mouth. The periapical films provide detailed images of individual teeth roots and surrounding bone, while the bitewings are designed to show the upper and lower teeth in one area, helping to assess interproximal caries and bone levels. The specific number of films can vary slightly based on the dental practice and the individual needs of the patient, but the range of 18 to 20 is commonly accepted within dental protocols. Other possible ranges do not provide enough coverage for a complete evaluation of the mouth, making them less suitable for a full mouth series. For example, fewer than 18 films may miss important diagnostic information about the patient's oral health.
