[Radiographic localization of the impacted cuspid in the upper maxilla]

Area of Science:

• Dentistry
• Radiology
• Maxillofacial Imaging

Background:

• Impacted maxillary canines are a common dental anomaly.
• Accurate diagnosis is essential for successful orthodontic or surgical intervention.
• Radiological imaging plays a vital role in identifying the position and impaction of these teeth.

Purpose of the Study:

• To review and summarize the various radiological diagnostic aids available for maxillary impacted canines.
• To highlight the advantages and limitations of each imaging modality.
• To provide guidance on selecting appropriate imaging techniques for clinical practice.

Main Methods:

• Comprehensive literature review of peer-reviewed articles.
• Analysis of studies focusing on diagnostic accuracy of different radiological techniques.
• Synthesis of information on conventional radiography, computed tomography (CT), and cone-beam computed tomography (CBCT).

Main Results:

• Conventional radiography (e.g., periapical, occlusal, panoramic X-rays) offers initial localization but limited 3D information.
• Computed tomography (CT) provides detailed cross-sectional views but involves higher radiation doses.
• Cone-beam computed tomography (CBCT) offers a balance of 3D visualization, accuracy, and reduced radiation exposure, making it a preferred modality.

Conclusions:

• Cone-beam computed tomography (CBCT) is currently the most effective radiological tool for diagnosing maxillary impacted canines.
• The choice of imaging modality should be based on clinical needs, diagnostic information required, and radiation safety.
• Continued research into advanced imaging techniques may further improve diagnostic capabilities.
