Study Notes
Intraoral Imaging
- Intraoral images are commonly used dental radiographs taken during examinations.
- Success in producing high-quality images involves correct placement, exposure, and processing techniques.
- Using the appropriate technique is dependent on the type of imaging medium: digital sensors, phosphor storage plates (PSPs), or conventional film.
Full-Mouth Survey (FMX)
- A complete dental examination includes dental images; the full-mouth survey (FMX) is typically preferred.
- An FMX comprises both periapical and bitewing images.
Types of Images
-
Periapical Images:
- Capture the entire tooth from the occlusal surface or incisal edge to about 2-3 mm beyond the apex.
- Essential for diagnosing conditions affecting teeth, roots, and surrounding bone; critical in endodontics and oral surgery.
-
Bitewing Images:
- Show upper and lower teeth in occlusion, revealing crowns and a small part of the root.
- Primarily used to detect interproximal decay, early periodontal disease, and assess restorations.
Number of Images
- The total number of images taken in a full-mouth series varies by dentist's preference and patient specifics.
- An adult FMX usually consists of 18 to 20 images: 14 periapical views and 4 to 6 bitewing views.
- The anterior region's imaging may vary based on sensor size and technique:
- Bisecting Technique: Utilizes three anterior views per arch with size #2 film.
- Paralleling Technique: Employs three to four size #1 films for each arch.
