Periodontal disease has a high prevalence in many countries. The early detection of periodontal disease is important in preventing tooth loss, and subsequently, maintaining the patient’s general health.

The current diagnostic approaches including clinical probing and intraoral radiography have shown several limitations in their reliability. Conventional diagnostic methods for periodontal disease include probing gingival tissues and performing radiographs to evaluate bony support.

Radiographs give us information about the amount and type of alveolar bone defect. Hence, they are valuable in the detection of bone defects, the estimation of their severity, the evaluation of the treatment outcome, and making prognosis.

Using two-dimensional (2D) radiographic methods, we can only observe the interproximal surfaces, and as a result, bone loss may be underestimated due to having a 2D view of three-dimensional (3D) structures. CBCT as a diagnostic tool is widely used in dentoalveolar surgeries, implantology, general /specialized dentistry (orthodontics,endodontics, periodontics, and forensic dentistry), and otolaryngology.
