Cone Beam Computed Tomography (CBCT) in General Dental Practice

Area of Science:

• Dentistry
• Radiology
• Medical Imaging

Background:

• Cone beam computed tomography (CBCT) is an advanced imaging technique in dentistry.
• CBCT provides higher radiation doses compared to conventional radiography, necessitating careful justification.
• Factors influencing radiation dose include field of view, exposure settings, rotation angle, and voxel size.

Purpose of the Study:

• To provide an overview of CBCT technology in dentistry.
• To summarize the latest European and UK guidelines on CBCT selection criteria.
• To guide general dental practitioners on the appropriate use of CBCT.

Main Methods:

• Review of current literature on CBCT in dentistry.
• Analysis of guidelines published by the European Commission (EC) and FGDP(UK).
• Synthesis of information on dose optimization and diagnostic yield.

Main Results:

• CBCT is a valuable tool when justified and used appropriately.
• Specific selection criteria are available to guide CBCT use.
• Optimizing exposure factors is crucial for minimizing patient dose.

Conclusions:

• CBCT use in dentistry should be based on clear clinical justification.
• Adherence to established selection criteria ensures safe and effective application.
• Minimizing radiation dose while maintaining diagnostic quality is paramount.
