چکیده

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 im age quality and elimination of processing, it has been extensively used in different fields of denti stry in recent years. the purpose of this study was comparison of conventional film and digital radiography in the proximal caries diagnosis. materials and methods: in this in vitro study, 60 extracted premolar teeth were selected and mounted in acrylic blocks. the teeth were radio-graphed using f-speed film and a complementary metal oxide semiconductor digital sensor (cmos). two observers evaluated interproximal surfaces for detection of presence and extent of caries. true caries depth was determined by his tological examination. the diagnostic accuracy of each radiographic system were assessed by means of receiver operating characteristic curve (roc) analysis. results: there was no significant difference be-tween two imaging modalities. the az values in cases without caries and dentinal caries were greater than caries restricted to enamel and den tino enamel junction (dej). the differences among observers also were not statistically sig-nificant. conclusion: both imaging modalities were com-parable in the detection of proximal carious le-sions.

The 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...

In vitro comparison of conventional film and direct digital imaging in the detection of approximal caries.

OBJECTIVES To compare the diagnostic accuracy of conventional film, unenhanced direct digital and inversion grayscale direct digital imaging in the detection of approximal caries. METHODS 150 approximal surfaces of extracted permanent molars and premolars were selected for the study on the basis of varying lesion depth. The teeth were radiographed using Ektaspeed Plus film; digital images wer...

Estimation 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...
