Digital Imaging in Dentistry: A Review
نویسنده
چکیده
X‐rays were discovered in 1895 by Wilhelm Roentgen. Digital radiology has overtaken conventional screen‐film radiography since it was introduced in the mid‐1980s.[1] Digital imaging uses sensor of solid‐state, and information is presented and stored as an image using a computer. The dawn of the digital era in dental radiography came in 1987 with the first digital radiography system called radio visio graphy (RVG), launched by Dr. Francis Mouyen. A physicist and charge‐coupled device (CCD) image sensor design engineer Paul Suni created the CCD image sensor technology that made the RVG digital radiography system a reality.[2] Main factor distinguishing digital systems from conventional is their response to incident radiation. An imaging system operates between the range of a completely bright and a completely dark image. The dynamic range of digital detectors is about 400‐fold compared to film‐screen.

Agreement of Bitewing and Digital Panoramic Radiographies in the Detection of Proximal Caries
Background & Aims: Conventional radiography is used for the diagnosis of problems such as dental caries and failure in root canal therapy. The diagnosis accuracy of conventional radiography is acceptable in the evaluation of anatomical and pathological structures. However, it seems that by using digital radiography we can obtain more information in this field. The aim of this study is to compar...
متن کاملComparison of cone beam computed tomography and digital radiography in detection of pulpal exposure in external cervical root resorption
Background and Aims: Pulpal exposures originated from the external cervical root resorptions have major effects on the treatment and prognosis. Therefore, the aim of this study was performed to compare the two different imaging systems-digital radiography with PSP (Photostimulable Phosphor) sensor in three horizontal different views and CBCT (cone beam computed tomography) images to assess the ...
متن کاملThe Comparison between Two Different Digital Panoramic Radiography Techniques in the Detection of Proximal Caries
Introduction: Although proximal dental caries are very common, clinical examinations cannot detect them all. Panoramic radiography has been widely used in dentistry for both diagnosis and screening. This study aimed to investigate and compare the efficacy of two digital panoramic radiography techniques in the diagnosis of proximal caries. Methods: A total number of 60 patients referred to a den...

Objectives: An efficient, safe, affordable and easily accessible measuring instrument for quantitative assessment of bone prior to dental implant placement enables more accurate treatment planning. Costly imaging modalities are neither widely available, nor affordable for some patients. This study sought to assess the efficacy of a newly designed digital bone gauge for measurement of bone width...

متن کاملEstimation of Remnant Dentin Thickness under Proximal Caries Using Digital Bitewing Radiography: An In-Vitro Study
Objectives: In restorative dentistry, it is essential to estimate the amount of remnant tooth structure after caries removal to make the best treatment plan. The present study was aimed to determine whether there is a correlation between the real thickness of remnant dentin under carious lesion and the radiographical measurement from photostimulable phosphor plates (PSPs). Methods: a whole numb...
