  1. Types of Radiographic Surveys Reference Reading: Chapter 16

  2. Types of Surveys • Intraoral- • Periapical Examination • Interproximal (bite-wing) Examination • Occlusal Examination • Extraoral • All of these types of examinations involve large areas of the skull and jaws. You will learn more about these later in the course.

  3. Periapical Examination • Purpose: • To examine the ENTIRE tooth, from tip of crown to tip of root (plus 2-3mm!) • Type of film used: • Periapical film • Comes from the Greek • “peri” = around • “apex” = tip of the root

  4. Periapical Radiographs

  5. Interproximal Examination • AKA the “Bite-wing” examination • Used to examine the crowns of both the maxillary and mandibular teeth on a single image. • Used to examine adjacent tooth surfaces (mesial and distal), as well as crestal bone.

  6. Bitewing Radiographs

  7. Bitewing Radiographs

  8. Occlusal Examination • Used to examine large areas of the upper or lower jaw. • Uses a #4 size film in adults; a #2 size film in kids.

  9. Occlusal Radiographs

  10. Occlusal Radiographs

  11. Complete Mouth Radiographic Survey (CMRS) • AKA: • Full Mouth Survey (FMS) • Full Mouth X-rays (FMX) • “complete series”

  12. CMRS • Defined as a series of intraoral dental radiographs that show all of the tooth-bearing areas of both jaws. • CMRS can include bite-wing radiographs or not.

  13. Tooth-bearing Areas • Regions of the jaw where the 32 teeth are normally located. • Tooth bearing areas include: • Dentulous areas • Teeth still present • Edentulous areas • Teeth no longer present

  14. Number of Films? • To include all teeth, and every tooth-bearing area, a CMRS will range from 14 – 20 images. • The number included on an individual survey is based upon • Radiographic technique used • Number of teeth present
