An introduction to digital radiography in dentistry

Area of Science:

• Dentistry
• Radiology
• Medical Imaging Technology

Background:

• Digital radiography has advanced dental imaging capabilities.
• Intra-oral and extra-oral systems offer different diagnostic perspectives.
• Understanding sensor technology is crucial for optimal image acquisition.

Purpose of the Study:

• To elucidate the fundamental principles of digital radiography.
• To review current intra-oral and extra-oral digital imaging systems.
• To compare the advantages and disadvantages of different digital sensor types, with a focus on orthodontic applications.

Main Methods:

• Explanation of digital radiography principles.
• Review of available intra-oral and extra-oral imaging systems.
• Comparative analysis of charge-coupled device (CCD) and phosphor storage plate (PSP) technologies.

Main Results:

• Digital radiography offers improved diagnostic potential over conventional methods.
• Two primary digital sensor types exist: CCD and PSP.
• Both CCD and PSP systems present unique benefits and drawbacks influencing clinical utility, particularly in orthodontics.

Conclusions:

• Digital radiography systems provide significant advantages in dental imaging.
• The choice between CCD and PSP technology depends on specific clinical needs and applications.
• A thorough understanding of these systems aids in selecting the most effective imaging approach, especially in orthodontics.
