Summary: (Critical) This program presents differences between the paralleling and bisecting techniques. Paediatric projection: The maxillary paediatric occlusal projection is used to examine the anterior teeth of the maxilla and is recommended for use in children 5 years old or younger. More comfortable: because the film is placed in. Describe the radiographic techniques in taking maxillary and mandibular cross-sectional occlusal radiographs. (IB).

The premolar bite-wing image should include the distal half of the crowns of the cuspids, both premolars, and often the first molars on both the maxillary and mandibular arches. In the other radiograph The x-ray beam is directed to pass between the contacts of the teeth being radiographed in the horizontal dimension, just as it does in the paralleling technique. SUPERVISED BY DR. SADAF ALI. Coronal Polishing and Dental Sealants, Shows images of the entire length of the tooth, plus 3 to 4 mm beyond the apices.
