What size film is used for anterior PAs in patients with narrow arches?

For patients with narrow arches, size 1 film is utilized for anterior periapical radiographs. This film size is smaller and specifically designed to fit comfortably in the smaller spaces of a narrow dental arch, allowing for optimal imaging of the teeth and supporting structures in the anterior region. The use of size 1 film helps ensure that the entire tooth and its surrounding area are captured clearly without the risk of overlapping or excessive negative space that larger films might introduce. Size 2 films are generally used for standard adult periapical images, while sizes 3 and 4 are even larger and are typically not suitable for narrow arches. The choice of film size is essential in achieving accurate radiographic results and ensuring patient comfort during the procedure.
