چکیده

o bjectives : dental caries are common and have a high incidence among populations. radiographs are essential for detecting proximal caries. the best technique should be recognized for accurate detection of caries. the aim of this study was to compare the accuracy of detection of proximal caries using intra oral bitewing, extra oral bitewing, improved interproximal panoramic, improved orthogonality panoramic and digital con- ventional panoramic radiographs. materials and methods : in this descriptive cross sectional study, 100 extracted human teeth with and without proximal caries were used. intra and extra oral radiographs were taken. images were evaluated and scored by two observers. scores were compared with the histological gold standard. the diagnostic accuracy of radiographs was assessed by means of receiver operating characteristic (roc) curve analysis (p<0.05). r esults : microscopic evaluation of proximal surfaces revealed that 54.8% of the sur- faces were sound and 45.2% were carious (with different depths). the differences in the area under the roc curve (az value) among the five techniques were not statisti- cally significant. c onclusion: improved interproximal panoramic and extra oral bitewing radiographs were superior to conventional panoramic radiography for detection of proximal caries ex vivo and should be considered for patients with contraindications for intra oral radi- ographs.

Accuracy of Digital Bitewing Radiography versus Different Views of Digital Panoramic Radiography for Detection of Proximal Caries

OBJECTIVES Dental caries are common and have a high incidence among populations. Radiographs are essential for detecting proximal caries. The best technique should be recognized for accurate detection of caries. The aim of this study was to compare the accuracy of detection of proximal caries using intraoral bitewing, extraoral bitewing, improved interproximal panoramic, improved orthogonality ...

Proximal caries detection accuracy using intraoral bitewing radiography, extraoral bitewing radiography and panoramic radiography.

OBJECTIVE To compare proximal caries detection using intraoral bitewing, extraoral bitewing and panoramic radiography. METHODS 80 extracted human premolar and molar teeth with and without proximal caries were used. Intraoral radiographs were taken with Kodak Insight film (Eastman Kodak Co., Rochester, NY) using the bitewing technique. Extraoral bitewing and panoramic images were obtained usin...

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...

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...

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...
