Periodontal examination involves evaluation of soft and hard tissue parameters to gauge gingival inflammatory changes and quantify attachment loss. Conventional radiographs are vital components of this process and can be used to assess the presence of calculus and other local factors to establish a diagnosis, prognosis, and periodontal treatment plan. The 2-dimensional nature of these images limits their utility. The advent of high-resolution cone beam computed tomography (CBCT) offers 3-dimensional images that might overcome these limitations. We discuss the use of conventional radiographic techniques as well as CBCT for evaluating, diagnosing, and treatment planning patients presenting for periodontal and/or implant therapy.
Key points
- •
A typical periodontal examination involves evaluation of soft and hard tissue parameters to gauge gingival inflammatory changes and quantify the extent of attachment loss.
- •
Conventional dental radiographs can be used to assess the presence of calculus and factors contributing to plaque accumulation, crestal bone heights, infrabony defects, furcation bone loss, and root anatomy.
- •
All of these factors must be taken into consideration to accurately establish a diagnosis, prognosis, and periodontal treatment plan.
- •
The advent of high-resolution cone beam computed tomography offers three-dimensional images that might overcome the limitations of two-dimensional images.
