Abstract
Cone Beam Computed Tomography (CBCT) has transformed dental radiology by offering detailed three-dimensional imaging, enhancing diagnostic precision, and improving treatment planning. This article explores CBCT's principles, wide-ranging applications, benefits, and limitations while addressing concerns such as radiation exposure, interpretation challenges, accessibility, and patient data privacy. Emerging technologies, including artificial intelligence (AI), low-dose imaging, and cloud-based platforms, are highlighted as solutions to these challenges. The inclusion of visual aids such as 3D reconstructions and comparative charts could further improve accessibility for readers. CBCT represents a paradigm shift in dental imaging and holds immense potential for future advancements.

Introduction
Dental imaging has evolved significantly over the years, with CBCT emerging as a pivotal tool in diagnostic and therapeutic procedures. CBCT offers unparalleled accuracy and spatial resolution, providing three-dimensional imaging essential for complex dental and maxillofacial cases. Unlike conventional radiography, CBCT minimizes distortions and delivers volumetric data critical for precise diagnosis and treatment planning [1,2]. This review aims to provide an in-depth analysis of CBCT’s principles, applications, advantages, and limitations while addressing concerns related to accessibility, data security, and radiation safety.
Principles of CBCT
CBCT operates using a cone-shaped X-ray beam that rotates around the patient, capturing multiple images from various angles. These images are reconstructed into a 3D dataset using algorithms, enabling clinicians to visualize anatomical structures in multiple planes. The isotropic voxel property of CBCT provides uniform spatial resolution, a critical advantage over conventional imaging [3,4].
Applications of CBCT
CBCT has versatile applications across various dental specialties
Endodontics: Identification of complex canal systems, root fractures, and periapical pathology [5,6].
Implantology: Precise assessment of bone quantity, density, and proximity to critical anatomical structures like the inferior alveolar nerve [7,8].
Orthodontics: Evaluation of craniofacial structures for treatment planning, airway analysis, and assessment of temporomandibular joint disorders [9].
Oral and Maxillofacial Surgery: Accurate localization of impacted teeth, cysts, tumors, and fractures [10,11].
Periodontics: Measurement of alveolar bone levels and detection of bony defects [12].
Advantages of CBCT
Compared to conventional imaging, CBCT offers several distinct benefits
*High Spatial Resolution: CBCT provides superior visualization of dental and maxillofacial structures [13].
*Volumetric Data: The ability to view images in axial, coronal, and sagittal planes facilitates comprehensive assessment [14].
*Reduced Artifacts: CBCT minimizes superimposition of structures, a limitation of 2D radiography [4].
*Enhanced Treatment Planning: Accurate measurements allow for precise surgical and orthodontic interventions [7].
Limitations of CBCT
Despite its advantages, CBCT is not without challenges
*Radiation Exposure: Although lower than conventional CT, CBCT radiation is higher than traditional 2D imaging. Strategies like low-dose protocols and ALARA (As Low As Reasonably Achievable) principles are essential to mitigate risks [15].
*Interpretation Challenges: The complexity of CBCT data requires specialized training, highlighting the need for continuing education [16].
*Financial Constraints: The high cost of CBCT machines limits accessibility in low-resource settings. Exploring shared-use models and financing options can alleviate this barrier [17].
*Patient Data Privacy: Cloud-based CBCT data storage raises concerns about cybersecurity. Compliance with regulations like HIPAA and GDPR is critical to ensure data security [18].
Future Trends and Technological Advancements
Artificial Intelligence (AI)
AI-integrated CBCT systems are enhancing diagnostic accuracy and reducing interpretation times. Machine learning algorithms can identify patterns and anomalies, paving the way for automated diagnosis [19].
Low-Dose Imaging
Innovations in X-ray technology are reducing radiation exposure, making CBCT safer for routine use [15]. Manufacturers are now offering systems with adaptive exposure control and noise reduction techniques [20].
Cloud-Based Platforms
Cloud storage facilitates the secure sharing of CBCT data between clinicians, improving collaborative care. However, encryption and multi-factor authentication are necessary to ensure data privacy [18].
Augmented Reality (AR) and Virtual Reality (VR)
Integration of AR and VR with CBCT data enables real-time visualization during surgeries, enhancing precision and outcomes [21].
Conclusion
CBCT has redefined dental imaging, offering precise, three-dimensional visualization critical for diagnosis and treatment planning. Addressing limitations such as radiation safety, financial barriers, and data privacy concerns will ensure broader adoption. Emerging technologies like AI, low-dose imaging, and cloud-based platforms promise to enhance the utility and accessibility of CBCT further, cementing its role as a revolutionary tool in dental radiology.
