introduction: endodontic treatment in pulpless immature teeth is challenging due to the lack of an apical stop. insertion of an apical plug is an alternative to conventional long-term apexification with calcium hydroxide. the aim of this study was to compare the apical microleakage of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement as apical plugs with three different...

BACKGROUND Diagnosis of external root resorption (ERR) cavities may be challenging, especially when no clinical signs are seen. Therefore, the aim of this study was to compare the efficacy of conventional intraoral film radiography, charge-coupled device (CCD) detector, photostimulable phosphor plate (PSP) detector, and cone beam computed tomography (CBCT) for the detection of ERR. METHODS Th...

introduction: the aim of this study was to compare a clearing technique with conventional radiography in studying certain features of the root canal system in single root premolars. a secondary aim was to assess inter examiner agreement for these features using radiographs. materials and methods: fifty-eight recently extracted single rooted premolars were included in this study. two standard pe...

INTRODUCTION The aim of this in vitro study was to compare the accuracy of radiography in assessing working length to Propex II apex locator. MATERIALS AND METHODS Thirty single canal extracted human teeth with patent apical foramen were selected. Access cavities were prepared. Anatomic length (AL) was determined by inserting a K-file into the root canal until the file tip was just visible at...

INTRODUCTION The success of endodontic retreatment is related to the complete removal of the obturation material from the root canal system. The aim of this study was to evaluate the efficacy of Mtwo R and ProTaper retreatment files in removing the Resilon/Epiphany system with or without chloroform during retreatment. MATERIALS AND METHODS Sixty distal roots of first mandibular molars were pr...

RVG is modern diagnostic method based on use of digital roentgen. Principle is use of so called CCD chip in RVG sensor (Figure 1) that put in patient’s mouth (3). The first dental digit...

introduction: objective: this study aimed to assess the possible variations in root canal anatomy and topography of the apices of first and second maxillary molars. materials and methods: a total of 67 first and second maxillary permanent molars were collected. access cavity was prepared and 2% methylene blue was injected. the teeth were demineralized by 5% nitric acid and cleared with methyl s...

Purpose: Root fracture is a clinical problem which often is difficult to detect and diagnose. As the root fracture detection is based on demonstration of a fracture line or lines, radiographic examination is important. The aim of this study was to compare diagnostic efficacy of direct digital radiography with conventional radiography for detecting experimental root fractures. Materials & Method...

PURPOSE The aim of this study was to compare the diagnostic accuracy of previously trained endodontists in the detection of artificially created periapical lesions using cone-beam computed tomography (CBCT) and digital periapical radiography (DPR). MATERIALS AND METHODS An ex vivo model using dry skulls was used, in which simulated apical lesions were created and then progressively enlarged u...
