Background: One of the significant stages during endodontic procedures is determining correct working length (WL). This study aimed to evaluate accuracy four electronic apex locators (EALs) (Root ZX mini, Raypex 6, Propex Pixi, and E-Pex Pro) cone-beam computed tomography (CBCT) radiographic measurement in actual WL (A-WL).

Osteochondroma is an osseous protuberance with cartilaginous growth potential that usually forms at the ends of long bones such as knee, hip, shoulder and joints(1). Osteochondromas are one of the most common benign tumours of bone, approximately 35% to 50% of all benign tumors and 8% to 15% of all primary bone tumors (2). Only about 1% of these occur within the head and neck region (1). The mo...

PURPOSE This study was performed to evaluate the feasibility of visualizing soft tissue lesions and vascular structures using contrast-enhanced cone-beam computed tomography (CE-CBCT) after the intravenous administration of a contrast medium in an animal model. MATERIALS AND METHODS CBCT was performed on six rabbits after a contrast medium was administered using an injection dose of 2 mL/kg b...

conclusion considering the similar diagnostic efficacy of all voxel sizes, 300 µm voxel size can be used with adequate efficacy for detection of external root resorption defects with minimal patient radiation dose and the shortest scanning time. background selecting a voxel size that yields minimal radiation dose with no significant compromise of the diagnostic accuracy of cone beam computed to...

objective: the diagnosis of vertical root fracture (vrf) in endodontically treated teeth is a clinical challenge due to lack of specific clinical and radiographic signs. although radiographic evaluation such as cbct is helpful, intracanal posts can produce artifacts and may impair the quality of cbct scans. this study aimed to compare the diagnostic accuracy of different resolutions of cbct in ...

Palatogingival groove is a rare developmental anomaly involving the lingual surface of the maxillary incisor and resulting in severe endodontic and periodontal lesions. This case report describes a multidisciplinary approach for the combined management of the endodontic and periodontal problems for successful rehabilitation of the involved tooth. Cone-beam computed tomography (CBCT) helped in c...

Introduction: Cone-beam CT (CBCT) is an imaging system which offers three-dimensional (3D), multiplanar images and has many advantages over computed tomography (CT) including shorter acquisition times for the resolution desired in dentistry, lower radiation dose to the patient, reasonable price and higher spatial resolution but CBCT scanners are unable to display actual Hounsf...

A right impacted mandibular third molar (IMTM) accidently displaced into the parapharyngeal space was dislodged successfully in only 5 minutes, with no sequel. Cone-beam computed tomography (CBCT) images were used to direct the removal. Five minutes is the shortest time having been reported. Considering that the event happens rarely, this report could add another case, and provide further refer...

Successful clinical management of teeth with odontogenic anomalies is quite challenging. Fusion can be defined as a union of two separate tooth buds at some stage in their development. This case report describes a multidisciplinary approach involving endodontic and restorative considerations for a successful, functional and esthetic rehabilitation of fused tooth using cone beam computed tomogra...

Introduction: Cone beam computed tomography (CBCT), is a relatively new imaging technique in dental and maxillofacial fields, with versatile abilities and applications. If the advantage of CBCT is well understood and established; the technique will be properly applied in dental planning and treatment along with tremendous benefits to the patients. This study was designed to evaluate the knowled...
