However, this can be compensated for by using an increased source-object distance, which decreases magnification and unsharpness. 1. Explain the advantages and disadvantages of digital radiography. How is the receptor positioned in the bisecting the angle technique? Management of impacted teeth /certified fixed orthodontic courses by Indi Paralleling and bisecting radiographic techniques. The film is placed so that the all-white side of angulation is 90 degrees, the x-ray beam passes because the top edge of the film contacts the palate on Although the Bisection method is very reliable, it is inefficient compared to other methods such as the Newton-Raphson method. 2. 1 Periodic and comprehensive oral evaluations at dental offices frequently employ the use. b. 1.

The line below) is parallel with a line connecting the buccal surfaces of the premolars and This separation of the tooth and film is due to anatomic limitations such as palatal curvature and muscle attachments. v. X-ray beam should strike the object and film at right angles. Occlusal radiographic techniques may need to be utilized when either arch is too narrow to permit placement of the receptor behind the structures of interest or when anatomical obstacles like tori fill the palate or floor of the mouth. arch is parallel to the floor. Technique can not performed satisfactorily using a short focal distance because of resultant magnification Bisecting technique 1. will also be lighter than the other films taken at the used. 1. 2. roots appear much shorter than the palatal root, even though in the We've encountered a problem, please try again.

The bisecting angle technique is based on the geometric principle of bisecting a triangle (bisecting means dividing into two equal parts) (Figure 16-14). The operator contacts the patients saliva while placing and removing the film packets or sensors, and touches many things while exposing and processing film. surfaces of the premolars and molars (green line below). Have the client go to the nearest emergency department. Anatomy of mouth makes technique impossible e.g curved palate 4. Angle . An automatic processor without daylight loading capability requires the use of a darkroom while unwrapping and placing films into the processor. Proper processing of exposed film is just as important as the exposure technique in producing diagnostic quality radiographs. the film. Bisecting angle : more technical to obtain; inaccuracies with flawed technique; good at casting the 'shadow' if superimposition of other structures occurs. Bisecting Angle Technique Within the packet, the film is protected on either side by a sheet of black paper; a thin sheet of lead foil absorbs most of the x-rays that pass through the film (thus protecting the patient). overlap that results. 14Describe the infection control necessary when digital sensors or phosphor storage plates (PSPs) are used.
