Notes part 4

QuestionAnswer
A bitewing view shows the crowns and interproximal areas of the maxillary and mandibular teeth and the areas of crestal bone on a single image.
Bitewing views are used to detect interproximal caries (tooth decay) and are particularly useful in detecting early carious lesions that are not clinically evident.
Bitewing views are also useful in examining crestal bone levels between the teeth.
Basic Principles of the Bitewing Technique: • The image receptor is placed in the mouth parallel to the crowns of both the upper and lower teeth.
Basic Principles of the Bitewing Technique: • The image receptor is stabilized when the patient bites on the bitewing tab or the bitewing film holder.
Basic Principles of the Bitewing Technique: • The central ray of the x-ray beam is directed through the contacts of the teeth, using +10 degrees of vertical angulation
When using a Rinn type of image receptor, red is the... universal color for bitewing holders.
The angulation of the PID is critical in the bitewing technique.
The image receptor-holding instruments and aiming rings provide the proper angulation.
When a bitewing tab is used, the operator must determine both the horizontal and the vertical angulation. Even a slight error will result in an image that is not diagnostic
Bitewing images are positioned parallel regardless of the technique.
Because the curvature of the arch differs in most adult patients, a total of four bitewing views are generally exposed to make sure the posterior contact areas are all open
The premolar bitewing image should include the distal half of the crowns of the canines, both premolars, and often the first molars on both maxillary and mandibular arches.
The molar view should be centered over the second molars.
The occlusal technique is used to examine large areas of the upper or lower jaw.
The occlusal technique is named this because the patient bites or “occludes” the entire film.
Occlusal radiographs can be used for the following purposes: • Locate retained roots of extracted teeth. • Locate supernumerary (extra) unerupted or impacted teeth.
Occlusal radiographs can be used for the following purposes: • Locate salivary stones in the duct of the submandibular gland. • Locate fractures of the maxilla and mandible. • Examine the area of a cleft palate.
THE BASIC PRINCIPLES OF THE OCCLUSAL TECHNIQUE The film is positioned with the white side facing the arch that is being exposed. The film is placed in the mouth between the occlusal surfaces of the maxillary and mandibular teeth.
THE BASIC PRINCIPLES OF THE OCCLUSAL TECHNIQUE The film is stabilized when the patient gently closes on the surface of the film.
Processed radiographs are arranged in anatomic order in holders, mounts
he American Dental Association (ADA) recommends the labial mounting method, where films are placed in the mount with the raised dots facing up (convex).
GUIDELINES FOR MOUNTING RADIOGRAPHS • Handle films only by the edges. • Learn the normal anatomy of the maxilla and the mandible.
GUIDELINES FOR MOUNTING RADIOGRAPHS Label and date the film mount before mounting the films. Include the patient’s full name, the date of exposure, and the dentist’s name. Mount films immediately after processing.
GUIDELINES FOR MOUNTING RADIOGRAPHS • Use clean, dry hands. • Use the order of the teeth to distinguish the right side from the left
GUIDELINES FOR MOUNTING RADIOGRAPHS • Use a definite order for mounting films. For example, start with maxillary anterior periapical films, proceed to mandibular anterior periapical and bitewing views, and finish with maxillary and mandibular posterior periapical views.
GUIDELINES FOR MOUNTING RADIOGRAPHS • Mount bitewing radiographs with the curve of Spee (occlusal plane between the maxillary and mandibular teeth) directed upward toward the distal. The result resembles a smile.
