Radiography: dental

Contributor(s): Richard Saunders, Simon Girling, Susanna Penman

Introduction

  • Essential in treatment plan and prognosis.
  • Dorsoventral view is more difficult to interpret; must be perfectly straight.
  • Perfectly straight lateral views allow accurate assessment of occlusion, whilst 10-20% oblique laterals improve visualization of individual arcades.
  • Intra-oral views are useful but not essential.
  • Intra-oral technique = non-screened dental film inside mouth.
  • Extra-oral technique = screened or non-screened film outside mouth.

Uses

Advantages

  • Small oral opening aperture makes oral cavity difficult to examine visually so radiography is essential, particularly for assessment below the gum line.
  • Rabbit will already be sedated/anesthetized for thorough oral examination   Dental examination  so easy to take radiographs at same time.
  • Essential to assess condition of tooth roots, bone density, tooth distortion, malocclusion, abscesses, osteomyelitis in order to make treatment plan and prognosis.
