CBCT: a revolutionary diagnostic aid for endodontic dilemmas

Area of Science:

• Dental Imaging
• Endodontics
• Radiology

Background:

• Endodontic management relies heavily on diagnostic imaging for accurate diagnosis and treatment planning.
• Conventional radiography (2D) has been the standard, but limitations exist in visualizing complex root canal anatomy and surrounding structures.
• The advent of cone-beam computed tomography (CBCT) represents a significant advancement in dental imaging.

Purpose of the Study:

• To review the fundamental principles of cone-beam computed tomography (CBCT) technology.
• To present the diverse applications of CBCT in contemporary endodontic practice.
• To highlight the advantages of CBCT over conventional imaging in endodontic diagnosis and treatment.

Main Methods:

• Review of existing literature on CBCT technology and its use in endodontics.
• Analysis of CBCT's capabilities in data acquisition and 3D image reconstruction for maxillofacial imaging.
• Evaluation of CBCT's diagnostic accuracy for endodontic conditions such as external resorption, root canal variations, and apical periodontitis.

Main Results:

• CBCT provides a 3D perspective, overcoming limitations of 2D radiography in endodontic assessment.
• CBCT systems offer small field-of-view images with adequate spatial resolution for endodontic applications.
• The technology enables accurate determination of the size, site, and extent of endodontic pathologies, including external resorption and apical periodontitis.

Conclusions:

• Cone-beam computed tomography (CBCT) is a valuable imaging tool that has revolutionized endodontic diagnosis and treatment.
• CBCT offers superior visualization of root canal anatomy and periapical tissues compared to conventional radiographs.
• Its application in endodontics aids in precise diagnosis, treatment guidance, and post-treatment evaluation, often at a lower radiation dose than conventional CT.
