Quantification of tooth displacement from cone-beam computed tomography images.
INTRODUCTION The objectives of this study were to demonstrate a method that could be used to quantify three-dimensional (3D) tooth displacement from cone-beam computed tomography (CBCT) images and to assess its accuracy. METHODS Images of the same mandible taken 2 weeks apart with no treatment were used. Four mandibular teeth-left lateral incisor, left canine, left first premolar, and left fi...
متن کاملComparison of transportation and centering ability using RECIPROC and iRace: A cone-beam computed tomography study
BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...
متن کاملComparison of in vivo 3D cone-beam computed tomography tooth volume measurement protocols
BACKGROUND The objective of this study is to analyze a set of previously developed and proposed image segmentation protocols for precision in both intra- and inter-rater reliability for in vivo tooth volume measurements using cone-beam computed tomography (CBCT) images. METHODS Six 3D volume segmentation procedures were proposed and tested for intra- and inter-rater reliability to quantify ma...
متن کاملAssessment of Accessory Mental Foramen by Cone-Beam Computed Tomography
Introduction: Any foramen in the buccal surface of mandibular body that transfers mental nerve and vessels except mental foramen, is called Accessory Mental Foramen (AMF). The objective of this study was the determination of the AMF using cone-beam computed tomography (CBCT). Materials and Methods: this descriptive study was done on 180 CBCT projections which were selected by convenience samp...
متن کاملPrevalence of Idiopathic Osteosclerosis on Cone Beam Computed Tomography Images
Objectives: This study was performed to investigate the prevalence of idiopathic osteosclerosis on cone beam computed tomography (CBCT) images of patients. Methods: In this descriptive, cross-sectional study, 240 CBCT scans of patients (125 women, 115 men) referred to a private oral and maxillofacial radiology clinic in Tehran in 2013 were selected and evaluated. Presence of idiopathic osteosc...
