dental radiology 1050 ch 16 intro to radiographic exams

radiographic inspection of teeth and intraoral adjacent structures they are: periapical examination, interproximal examination (bitewing teet, inbetween teeth), and occlusal examination = the whole biting surface either maxillary or mandibular

• purpose: to examine the entire tooth (crown and root) and supporting bone
• film type: periapical film (PAX)
• Technique: paralleling technique and bisecting technique

• purpose: to examine crown of both the maxillary (upper) and mandibular (lower) teth on a single film.  proximal examination of adjacent tooth surfaces and crestal bone
• film type:  bite-wing film (BWX)
• technique: bitewing technique

• purpose: to examine large areas of the maxilla (upper jaw) or the mandible (lower jaw) on one film
• film type: occlusal film
• technique: occlusal technique

• a series of intraoral dental radiographs that show all the tooth-bearing areas of the maxilla and mandible
• consist of a combination of periapical and bitewing radiographs. we do 18. 
• dentulous - areas that exhibit teeth
• endentulous - areas where teth are no longer present

areas that exhibit teeth

areas where teeth are no longer present

• must show images with optimum density, contrast, definition and detail
• must show images with the least amount of distortion possible. same size and shape as object being radiographed
• FMX (full mouth) must include all tooth-bearing areas
• PAZ (periapical) must show entire crowns and roots of the teeth being examined as well as 2-3 mm beyond the root apices
• BWX (bite wings) must show open contacts or interproximal tooth surfaces not overlapped

• inspection of large areas of the skull of jaws
• panoramic, ceph

• based on individual needs of the patient
• professional judgement made by the dentist (number, type, frequency)
