a novel thresholding based algorithm for detection of vertical root fracture in non_endodontically treated pre molar teeth
in this paper, an efficient algorithm is proposed for detection of vertical root fractures (vrfs) in periapical (pa), and cone-beam computed tomography (cbct) radiographs of nonendodontically treated premolar teeth. pa and cbct images are divided into some sub-categories based on the fracture space between the two fragments as small, medium, and large for pas and large for cbcts. these graphics...
متن کاملVertical root fracture in endodontically versus nonendodontically treated teeth: a survey of 315 cases in Chinese patients.
OBJECTIVE The purpose of this study was to compare endodontically versus nonendodontically treated teeth with respect to clinical features, including patient age and gender and tooth types of vertical root fractures. STUDY DESIGN A total of 315 consecutive cases of vertical root fracture occurring in 274 Chinese patients during a 1 3-year period were reviewed. Age and gender, as well as tooth...
متن کاملAccuracy comparison of CBCT scan and radiography with two different horzental angle in vertical root fracture detection of endodontically treated teeth
Background and Aims: Accurate diagnosis of vertical root fracture (VRF) is a fundamental importance in endodontics. Because of poor prognosis of VRF, digital radiographs with two horizontal angles have limitations in VRF detection. Also, Gutta-percha can produce artifacts that impair CBCT scan accuracy. The aim of this study was to compare accuracy of CBCT and digital radiography system in vert...
متن کاملEffect of Different Instrumentation Techniques on Vertical Root Fracture Resistance of Endodontically Treated Teeth
STATEMENT OF THE PROBLEM Vertical root fractures are catastrophic events that often result in tooth extraction. Many contributing factor are associated with increasing incidence of vertical root fracture. Root canal preparation is one of the predisposing factors which can increase the root susceptibility to vertical fracture. PURPOSE The aim of this study was to compare the effects of three d...
متن کاملThe ability of cone-beam computerized tomography to detect vertical root fractures in endodontically treated and nonendodontically treated teeth: a report of 3 cases.
A definitive diagnosis of vertical root fracture (VRFs) is often a challenging task for clinicians. Two-dimensional periapical radiographs (PRs) may be not helpful in such a diagnosis when the x-ray beam is not parallel to the plane of the fracture line. This report presents a set of 3 cases in which 1 endodontically treated and 2 nonendodontically treated mandibular molars were diagnosed with ...
