The aim of this study was to evaluate the accuracy of linear measurements made on conventional and digitized periapical and panoramic radiographic images of dry human hemi-mandibles. Images from the posterior region of 22 dry human hemi-mandibles were obtained by conventional panoramic and periapical radiography technique. Using a digital caliper, 3 vertical measurements were marked directly on...

The periapical area in teeth with chronic lesions is characterized by changes in the adjacent bone structure and periodontal ligaments, as well as in the cement and dentine. In a large percentage of cases, the apical physiological constriction is ether absent or expanded. The absence of a constriction makes it a challenge to achieve satisfactory treatment results.The present case report describ...

INTRODUCTION One of the common findings encountered by the clinician at the end of orthodontic treatment is the apical root resorption. Root resorption occurs to various degrees. A severe form of root resorption is characterized by shortening of root for more than 4 mm or more than one-third of the total tooth length. A low incidence rate of resorption is observed based on radiographic findings...

The presence or absence of periapical radiolucencies, after a predetermined healing period, have been used as a criteria for therapeutic success or failure in endodontic treatment. However, in radiologic diagnosis it has been shown that variations within and between examiners are substantial. In the present study six endodontists evaluated the periapical tissues in radiographs of 119 endodontic...

Introduction Recurrent or secondary caries develops at the margin of restorations and causes restorative failure. We conducted this study to compare the performance of Phosphor Storage Plate (PSP) and Cone Beam Computed Tomography (CBCT) scan in detecting buccal recurrent caries under amalgam and composite resin restorations. Materials and Methods Class V cavities were prepared on the buccal...

Context: The accurate determination of working length (WL) has a major impact on the outcome root canal treatment. Aim: aim present clinical study was to compare accuracy using Cone Beam Computed Tomography (CBCT), Periapical radiograph and Electronic apex locator in teeth with periapical lesion. Settings Design: Randomised control trial. Materials Method: This conducted 30 patients an initial ...

Impacted canines are not uncommon in clinical practice, but intraosseous movement of impacted canines crossing the midline (transmigration) is a rare phenomenon. We report 4 cases of mandibular canine transmigration to emphasize the need to supplement periapical radiographs with a panoramic radiographic examination in patients with over-retained deciduous canines or missing permanent canines.

In the diagnosis and exact localization of root curvatures perforations "three-angled technique radiographic tracing" is employed consists in three periapical radiographs . The aim this study was to veriry if with technique's methodization it possible reduce number exposures these diagnoses. Eight-four exlrated teeth were pelforated radiographed. Two given observers and, later, third radiograph...

INTRODUCTION Digital radiographic imaging systems have undergone tremendous improvements since their introduction. Advantages of digital radiographs over conventional films include lower radiation doses compared with conventional films, instantaneous images, archiving and sharing images easily, and manipulation of several radiographic properties that might help in diagnosis. METHODS A total o...
