New dimensions in endodontic imaging: Part 2. Cone beam computed tomography

Area of Science:

• Dentistry
• Radiology
• Endodontics

Background:

• Cone beam computed tomography (CBCT) provides undistorted 3D imaging of the maxillofacial skeleton and dental structures.
• CBCT offers a significantly lower effective radiation dose compared to conventional computed tomography (CT).
• Early detection and accurate assessment of endodontic problems are crucial for effective patient management.

Purpose of the Study:

• To review the current literature on the applications of CBCT in endodontics.
• To discuss the limitations of CBCT in managing endodontic problems.
• To highlight the role of CBCT in diagnosing and managing periapical diseases, root fractures, and root canal anatomy.

Main Methods:

• Literature review of studies on CBCT applications in endodontic management.
• Analysis of diagnostic capabilities of CBCT for periapical and resorptive lesions.
• Evaluation of CBCT's role in assessing root fractures and alveolar bone topography.

Main Results:

• CBCT enables earlier detection of periapical disease compared to periapical views.
• It accurately assesses the size, extent, nature, and position of periapical and resorptive lesions.
• CBCT is effective in evaluating root fractures, root canal anatomy, and alveolar bone topography.

Conclusions:

• CBCT is a valuable tool in endodontic management, offering superior diagnostic information.
• Its applications include early detection and precise assessment of various endodontic pathologies.
• Understanding CBCT's limitations is essential for optimal clinical application in endodontics.
