Dental Imaging Array Technologies: A Review and Update

Sanat Kumar Bhuyan, Rupsa Nayana


Digital radiography has evolved and co-existed with the dental imaging since four decades. The complete replacement of digital imaging in place of conventional screen-film combination has proved to be beneficial to the new era of dentistry. Because of low cost, higher patient comfort, increased dose efficiency, and greater dynamic range of digital detectors with possible reduction of radiation exposure to the patient, the digital imaging has created a new place for itself not only in medical radiology but in dentistry as well. The future will be digital, irrespective of CCDs, CMOS, or phosphor plates the advancement in the field of imaging is rapid and progressive with constantly replacing the older ones. The present paper discusses thoroughly about the various advancements in digital imaging starting from CCDs to flexible phosphor plates. Digital imaging, a substitute for conventional film radiography, has ventured into the arena of dentistry as well and revolutionised the imaging concepts of Oral Health Care Professionals. 

KEYWORDS: CCD, CMOS, Phosphor plate, Digital imaging, Computed radiography, Direct radiography, Digital imaging, Conventional film.
