A range of lasers is now available for use in dentistry. This paper summarizes key current and emerging applications for lasers in clinical practice. A major diagnostic application of low power lasers is the detection of caries, using fluorescence elicited from hydroxyapatite or from bacterial by-products. Laser fluorescence is an effective method for detecting and quantifying incipient occlusa...

background the first commercial system for digital radiography was introduced in 1987, and it has evolved a great deal since then. currently, it is possible to enhance images in digital radiography. objectives the aim of this study is to evaluate the diagnostic accuracy of image enhancement in direct digital radiography as it relates to interproximal carries assessment. conclusions using these ...

STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Operative Department of Fatima Jinnah Dental Hospital, Karachi, from January to May 2009. METHODO...

The purpose of this report was to respond to aspects of the RTI/UNC systematic review relating to the radiographic diagnosis of dental caries. The systematic review was commissioned as part of the NIH Consensus Development Conference on Diagnosis and Management of Dental Caries Throughout Life. The systematic review evaluated the dental literature from 1966 to 1999. Well-defined search criteria...

background and aims. the aim of the present study was to compare the effect of application of an image processing mode of a colorizer on the efficacy of the detection of interproximal carious lesions viewed in direct digital radiography. materials and methods. a total of 102 proximal surfaces of extracted human premolars on direct digital images were evaluated by three observers with and withou...

OBJECTIVES This study aimed to assess the diagnostic value of conventional and digital radiography for detection of cavitated and non-cavitated proximal caries. MATERIALS AND METHODS Fifty extracted human premolars and molars were mounted in a silicone block. Charge-coupled device (CCD) and photostimulable phosphor plate (PSP) receptors and intra-oral films were exposed with 60 and 70 kVp wit...
