The occlusal view provides the broadest visualization of the floor of the mouth and anterior palate because it captures a large area of the maxilla and mandible in a single image. This view uses a horizontal angulation that encompasses the entire anterior region, allowing assessment of anatomical structures, pathologies, and foreign bodies in the floor of the mouth and palate. Unlike bitewing or periapical views, which focus on limited areas, the occlusal radiograph enables comprehensive evaluation of soft tissue and bone contours in the anterior oral cavity. This makes it invaluable for diagnosing cysts, fractures, and salivary gland stones in these regions. Panoramic views are extraoral and not considered intraoral radiographs.
