precise localization of the third molars in relation to the inferior alveolar nerve canal is critical from a clinical point of view and strongly affects the surgical treatment outcome. recently, by using three-dimensional modeling software, the relationship of third molar root apices and inferior alveolar nerve canal can be better understood. in this study, the spatial relationship of two surgi...

introduction: the aim of this study was to compare the dentine removing efficacy of gates-glidden drills with hand files, protaper and oneshape single-instrument system using cone-beam computed tomography (cbct). methods and materials: a total of 39 extracted bifurcated maxillary first premolars were divided into 3 groups ( n =13) and were prepared using either gates-glidden drills and hand ins...

to evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an iranian population by means of cone beam ct (cbct) images.four hundred cbct images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. vertucci's classification was used to evaluate the number of roots, number of root canals, root leng...

objectives:  the efficacy of adding platelet-rich plasma (prp) to demineralized freeze-dried bone allograft (dfdba) in order to improve the clinical and radiographic results obtained in treatment of deep periodontal intrabony defects has yet to be fully elucidated. materials ­and methods: this double blind, split-mouth randomized controlled clinical trial was conducted on 12 patients with two c...

objectives: the optimal goal of radiography is to provide high-quality diagnostic images with the least patient radiation dose. the aim of this study was to evaluate the accuracy of cone-beam computed tomography (cbct) and intraoral photostimulable phosphor plate (psp) digital and film-based conventional radiography for detection of artificial cancellous bone defects. materials and methods: fiv...

background and aim: clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. the aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (psp) and cbct in the detection of horizontal root fracture (hrf) and vertical root fracture (vrf). materials and methods: for this experim...

objectives this study aimed to evaluate the safety and effectiveness of transarterial ethanol ablation (tea) for the treatment of hcc with pvtt. methods patients were treated with tea for pvtt under cone-beam computed tomography and traditional transarterial chemoembolization (tace) with epirubicin for intrahepatic lesions. results seventeen men were successfully treated with tace plus tea. the...

introduction: coronal anatomic variations in permanent maxillary molars are unusual; conversely variations involving the number of root canals or number of roots are more common. methods and materials: this case report presents a successful nonsurgical endodontic therapy of left maxillary first molar with three roots and seven root canals. this unusual morphology was diagnosed using a dental op...
