Statistical elimination based approach to jaw and tooth separation on dividing cells and young cells. The correct answer is: 99% heat and 1% x-rays. The bitewing radiograph (BW) is an image that depicts the maxillary and mandibular crowns of the teeth, providing a clear image of the interproximal surfaces of the teeth and allowing for detection of interproximal caries. The molar image should show the distal of the second premolar and completely include the terminal molars on each side of the patient's mouth. Panoramic imaging allows the dentist to do all the following EXCEPT - determine if the tooth is percussion sensitive 35.
