In vitro Comparison of Conventional Film and Direct Digital Radiography in Proximal Caries Detection
Introduction: Various systems for intraoral digital radiography have been available as an alternative to film–based radiography. In consideration of several advantages of digital radiography such as less patient absorbed dose, manipulation of image quality and elimination of processing, it has been extensively used in different fields of dentistry in recent years. The purpose of this study wa...
PURPOSE This laboratory study compared visual-tactile examination with conventional radiographs, digital radiographs, and laser fluorescence in the detection of occlusal occult caries on extracted premolar teeth. METHODS Extracted premolars without obvious caries or restorations were collected from school dental clinics. Occlusal surfaces of 320 extracted premolars were examined visually with...
AIM The purpose of this laboratory research was to compare the accuracy of digital and conventional bitewing radiographs in the diagnosis of recurrent caries under class II amalgam restorations. METHODS AND MATERIALS This study involved 82 posterior intact teeth in which class II amalgam boxes were prepared. Carious lesions were simulated in half of the proximal boxes in the intersection betw...
dental caries, a progressive bacterial damage to teeth, is one of the most common diseases that affects 95% of the population and is still a major cause of tooth loss. unfortunately, there is currently no highly sensitive and specific clinical means for its detection in its early stages. the accurate detection of early caries in enamel would be of significant clinical value. since, it is possib...
the article entitled “accuracy of digital subtraction radiography in combination with a contrast media in assessment of proximal caries depth” which appeared in j dent res dent clin dent prospect 2008; 2(3):77-81 incorrectly listed the second author’s affiliation as department of oral and maxillofacial radiology, shahid beheshti university of medical sciences. the correct affiliation of sara eh...
BACKGROUND AND AIMS Radiography is used to diagnose the demineralization process and carious lesions; however, conventional radiography and direct digital images do not show these lesions when the amount of demineralization is less than 40%. Digital subtraction radiography has recently been used to improve the diagnostic quality of these le-sions. The purpose of this study was to compare the ca...
The detection of dental decay has conventionally been dependent upon direct visual assessment of the dried tooth surface under good illumination, tactile assessment of open dental caries using a probe to help clean debris within fissures, clinical experience and the use of dental radiography. Studies have shown considerable variation berween clinicians in the detection of dental caries. Recent ...
Introdouction:The study aimed to compare the accuracy of proximal caries detection by dental practitioners using two different systems, direct digital system and conventional films, under routine environmental conditions. Materials and methods: Eleven extracted human posterior teeth were mounted on wax frames and were exposed using the direct digital system and conventional films. Seventy-four ...
background and aims. early diagnosis of external root resorption is important for accurate treatment. the purpose of this study was to compare the efficacy of a charge-coupled device (ccd) sensor and a photostimulable phosphor (psp) plate receptor in the diagnosis of artificial external root resorption. materials and methods. in this diagnostic in-vitro study, 40 maxillary incisors were mounted...
Introduction: Radiography is one of the most important diagnostic methods for evaluation of dental caries. On the other hand, the least amount of radiation along with high quality is a main gold standard. The purpose of this study was to compare the diagnostic accuracy of Primax, Insight Radiographic films, and direct digital images (Schick CMOS-APS), in detection of interproximal natural Carie...
