introdouction: the purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (pmi), mandibular cortical width (mcw), and antegonial notch depth (ad), in digital panoramic radiographs. materials and methods: pmi, mcw, and ad were calculated in digital panoramic radiographs of ...

objective: after introduction of digital radiography into dentistry several methods of image acquisition were accessible in the field of dentistry. in many instances it is necessary to digitize analog images. there is no overall acceptable method for image digitization so all different types of images can be comparable. the objective of this study was to compare the diagnostic accuracy of diffe...

OBJECTIVES To compare the differences between conventional radiography and digital computerized radiography (CR) in patients presenting to the emergency department. METHODS The study enrolled consecutive patients presenting to the emergency department who needed chest radiography. Quality score of the radiogram was assessed with visual analogue score (VAS-100 mm), measured in terms of millime...

objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. despite cone beam computed tomography (cbct) has significantly enhanced image quality compared to digital radiography (dr) which aid the diagnosis, artifacts has remained as a problem in vrf detection . th...

Introduction: The aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.Methods: Thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. After access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. Wi...

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...

introduction: inappropriate condensation of gutta-percha or improper use of sealer can lead to voids in root canal filling material and consequent failure of the treatment. timely detection of voids within root canal filling may prevent complications. in this study, we compared the accuracy of digital and conventional radiograph for detecting voids within root canal fillings . materials & metho...

Objectives: This review article is aimed to determine the accuracy of extraoral periapical radiography as a determinant working length in endodontic treatment and advantages disadvantages this technique.
 Review: Endodontic dental for damages reaching pulp which aims maintain tooth. One way succeed an accurate length. The can be determined by intraoral examination but some people are sensi...
