The Evaluation of Root Fracture with Cone Beam Computed Tomography (CBCT): An Epidemiological Study

Abstract

BackgroundThe aim of this study was evaluation of the cone-beam computed tomography (CBCT) image of 50 patients at the ages of 8-15 suspecting root fracture and root fracture occurred, exposed to dental traumatic. In additionally, this study was showed effect of crown fracture on root fracture healing.Material and MethodsAll of the individuals included in the study were obtained images with the cone-beam computed tomography range of 0,3 voxel and 8.9 seconds.(i-CAT®, Model 17-19, Imaging SciencesInternational, Hatfield, Pa USA).The information obtained from the history and CBCT images of patients were evaluated using chi-square test statistical method the mean and the distribution of the independent variables.Results50 children, have been exposed to trauma, was detected root fracture injury in 97 teeth. Horizontal root fracture 63.9% of the 97 tooth, the oblique in 31.9%, both the horizontal and oblique in 1.03%, partial fracture in 2.06% ,and both horizontally and vertical in 1.03% was observed.The most affected teeth, respectively of, are the maxillary central incisor (41.23% left, right, 37.11%), maxillary left lateral incisor (9.27%), maxillary right lateral incisor (11.34%), and mandibular central incisor (1.03%).ConclusionsCrown fractures have negative effects on spontaneous healing of root fractures. CBCT are used selected as an alternative to with conventional radiography for diagnosis of root fractures. In particular, ıt’s cross-sectional image is quite useful and has been provided more conveniences seeing the results of diagnosis and treatment for clinician.

CBCT in orthodontics: a systematic review on justification of CBCT in a paediatric population prior to orthodontic treatment

“…In vivo studies of 3D imaging in paediatric trauma are very rare; for that reason, we included some in vitro and adult studies, although the exclusion criteria were set for these studies. This review suggested that CBCT is more accurate to assess vertical root fractures than 2D imaging, which is also in accordance with the included studies (25–27,66). Despite the advantages, a CBCT scan exposes the patient with additional radiation; hence, it should only be reserved for suspected root fractures diagnosed initially by clinical signs and 2D radiographs.…”

“…According to Doğan et al . (25), root fractures are easily overseen on 2D radiographs, due to the direction of the X-ray beam. Evaluation of root fractures should be done by several periapical radiographs at different angles.…”

Cone beam computed tomography in Endodontics – a review of the literature

“…Crown root fractures. Cone beam computed tomography permits a more accurate visualization of the course of the often oblique nature of these fractures and the relationship of the fracture to the pulp, periodontium and crestal bone, thus facilitating management (Martos et al 2017, Do gan et al 2018.…”

Assessment of fractures in endodontically treated teeth restored with and without root canal posts using high-resolution cone beam computed tomography

“…Three factors are important to classify root fractures: origin, location, and pattern ( 4 ). In their study with cone beam computed tomography (CBCT), Doğan et al ( 5 ) found that the additional presence of crown fractures has a negative effect on the spontaneous healing of root fractures. Most teeth extracted due to root fracture were teeth with prosthetic restorations after root canal treatment and dental fillings ( 6 ).…”
