INTRODUCTION Endodontic diagnosis depends on accurate radiographic examination. Assessment of the location and extent of apical periodontitis (AP) can influence treatment planning and subsequent treatment outcomes. Therefore, this systematic review and meta-analysis assessed the diagnostic accuracy of conventional radiography and cone-beam computed tomographic (CBCT) imaging on the discriminati...

abstract background and aim: cone beam computed tomography (cbct) produces high-quality data in periodontal diagnosis and treatment planning. the aim of this study was to compare the accuracy of cbct with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  methods and materials: in this diagnostic research, two hundred and eighteen artificial osseous ...

introduction: the aim of this study was to compare the diagnostic value of cone-beam computed tomography (cbct) and periapical (pa) radiography in detecting internal root resorption. methods and materials: eighty single rooted human teeth with visible pulps in pa radiography were split mesiodistally along the coronal plane. internal resorption like lesions were created in three areas (cervical,...

Gingival and periodontal diseases in their various forms have affected human since the dawn of history. The earliest historical records dealing with medical topics revealed an awareness of periodontal diseases and need for treatment.1 The diagnosis of periodontal diseases which involve the soft and hard tissue destruction should be made systematically and should include both clinical and radiog...

the use of mammography film-screen is limited in general radiography. the purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). fourteen other radiographs were ...

This paper introduces a radiographic system for imaging marine sedimentary structures in situ, as an alternative to the currently used intrusive and tedious process of imaging extracted core samples in the laboratory. The system consists of a small isotopic source and a film incorporated into a device that can penetrate the sediment. The design of the device is introduced, and the results of mo...

A thin-film balance employing either a Sheludko capillary or a Mysels-inspired porous-medium film holder provides a direct measurement of disjoining-pressure isotherms in free, liquid thin films. However, each film holder suffers its own distinct disadvantages spanning non-uniform and slow liquid exchange, a limited range of measurable disjoining pressures, an inability for reuse, and a require...

The purpose of this study was to determine the need for supplemental periapical radiographs in planning restorative services and pulp treatment for primary molars when a child’s bite-wing radiographs were taken with No. Oor No. 2-size film. Forty-eight good quality bite-wing radiographs were selected from patients 5-7 years of age and sorted into four groups containing 12 films classified accor...

OBJECTIVES Our aim was to compare periapical radiography and cone beam CT (CBCT) for assessment of the periapical bone defect 1 week and 12 months after root-end resection. METHODS 50 patients (58 teeth) with a persisting apical periodontitis in a root-filled tooth (incisor, canine or premolar) were treated with root-end resection. 1 week and 12 months post-operatively, a CBCT scan (NewTom 3G...
