estimation of remnant dentin thickness under proximal caries using digital bitewing radiography: an in-vitro study
نویسندگان
چکیده
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 number of 68 unrestored permanent human molar and premolar teeth with 82 proximal carious surfaces were mounted in an artificial arch. digital bitewing radiographs with psps were taken, carious lesions were removed and radiographic imaging was repeated. teeth were sectioned mesiodistally in two parts and thickness of remnant tooth structure to pulp was measured. measurements of remnant dentin under caries from radiographic images and teeth structures were compared. result: the mean measurements of remnant dentin on primary radiographs were statistically different from the measurements on teeth structures. the mean thickness of remnant dentin on tooth structure was around 30% less than what measured on radiographic image. conclusion: the real thickness of remnant dentin under caries is about 70% of its thickness measured on digital bitewing radiographs prepared by psps as image receptor.

متن کاملProximal 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...
متن کاملIn 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...
متن کاملAccuracy 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 ...
