The function of the __________ filter in the x-ray tube is to __________. What does a vertical bitewing X-ray show? Which wavelength of x-ray produces greater energy and usefulness? See our Clear Which film holder can aid in positioning the film during an endodontic procedure, because it fits around the dam clamp and the endodontic instruments? Good for patients with bone loss. films exposed, processed, and mounted should be kept in the patients are adults. The __________ film holder can be used to aid in positioning the film during the root canal procedure because it fits around a rubber dam clamp and allows space for endodontic instruments and filling materials to protrude from the tooth. Both storage phosphor (SP) plates and charge-coupled devices (CCDs) must be wrapped in a protective sleeve before being placed in the patients mouth, and CCDs require a sensor holder. Taken with the film or sensor place in a vertical direction (vertical bitewings), these radiographs also show bone volume and density, for evaluation of periodontal health (peri around; odont tooth). To correct an elongated image on an x-ray view, the vertical angulation needs to be. entire crown and root structure of appropriate teeth centered on canine should be at the midpoint of the film with lateral, canine,
