CBCT in Periodontics

Cone-beam computed tomography (CBCT) was introduced to the dental community more than 20 years ago.¹ This technology gathers quality images of the dentition and surrounding structures that provide valuable, real-time information for dental implant planning. More recently, CBCT imaging has been found to aid in the diagnosis and treatment of various periodontal conditions.² But this added radiation dose and cost, and how they compare with conventional diagnostic imaging, should be considered. No matter how low the radiation dose, it is deemed excessive if it does not improve therapeutic outcomes.^3,4

Currently, a complete periodontal assessment and a full-mouth radiographic series are still key components in establishing a periodontal diagnosis.⁵ However, an exact measurement of the alveolar bone height and morphology using CBCT scans could enhance accuracy.⁶ However, the decision to use this imaging modality must be reached on a case-by-case basis, because the increased radiation exposure may not be warranted for all patients.⁵
