Which film size corresponds to the dimensions of 1 1/16 x 2 1/8?

The film size that measures 1 1/16 x 2 1/8 inches corresponds to the dimensions typically associated with No. 2 film. This film size is commonly used for periapical and bitewing radiographs in dental imaging.

No. 1 film measures 1 x 2 3/8 inches and is often used for specific areas, such as pediatric cases or narrow anterior teeth. No. 3 film is larger than No. 2, measuring 2 1/4 x 3 inches, and is primarily used for bitewing radiographs in a two-film format. No. 4 film is much larger and usually measures 5 x 7 inches, intended for extraoral views.

Understanding these dimensions is crucial for selecting the appropriate film size for different types of radiographic examinations, ensuring optimal imaging and diagnostic quality for dental assessments.
