Cone beam computed tomography--current understanding and evidence for its orthodontic applications?

Area of Science:

• Dentistry
• Radiology
• Orthodontics

Background:

• Cone beam computed tomography (CBCT) is an advanced imaging technique for the craniofacial complex.
• CBCT provides high-resolution, three-dimensional (3D) imaging with relatively low radiation doses.
• There has been a substantial increase in CBCT research publications over the last decade.

Purpose of the Study:

• To review the literature on CBCT applications in orthodontics.
• To evaluate the current evidence regarding the impact of CBCT on clinical outcomes.
• To identify areas for future research in CBCT imaging interpretation.

Main Methods:

• Systematic literature review of CBCT applications in orthodontics.
• Analysis of evidence supporting the enhancement of clinical treatment decisions by CBCT.
• Discussion of the implications of detailed CBCT findings.

Main Results:

• Despite its popularity, there is a lack of clear evidence that CBCT data substantially improves orthodontic treatment decisions.
• The interpretation of CBCT images and understanding their clinical implications remain critical challenges.
• Detailed visualization of the dentofacial skeleton does not automatically translate to meaningful clinical impact.

Conclusions:

• Current evidence does not support a significant enhancement of clinical treatment decisions with CBCT in orthodontics.
• Future research should prioritize the interpretation of CBCT images and understanding their clinical relevance.
• The clinical utility of CBCT is limited without improved interpretation and integration into treatment planning.
