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...
abstract : horizontal root fractures in permanent teeth are uncommon injuries among dental traumas. the principle of treating horizontal root fractures of permanent teeth is repositioning and fixation of fractured segment. diagnosis of tooth fractures based on radiographic findings and the fracture healing process are affected by factors before and after injury. the present case reports the tre...
Background and Aims: Radiographic examination is a necessary step in diagnosis of horizontal root fracture. The purpose of this study was to determine the sensitivity and specificity of single radiograph for detection of horizontal root fracture. Materials and Methods: In this analytical-descriptive study, 30 human freshly extracted teeth were used. Using a hammer and clamp, the teeth were div...
Among dental traumas, horizontal root fractures are relatively uncommon injuries. Proper initial management and periodical evaluation is essential for the successful treatment of a root-fractured tooth. If pulpal necrosis develops, endodontic treatment is indicated, exclusively for the coronal fragment. Fragment diastases exert a great influence on healing at the fracture line and on pulpal nec...
Root fractures are defined as fractures involving dentine, cementum, and pulpal and supportive tissues. They comprise about 0.5–7% of all dental injuries. Horizontal root fractures are commonly observed in the maxillary anterior region and 75% of these fractures occur in the maxillary central incisors. Case report: This case report is about a 26-year-old male referred to the endodontic departme...
root fracture injuries affect up to 7% of permanent teeth. this type of injury is rarely seen in teeth with open apices and depending on the fracture site, the prognosis is good. this case report describes a horizontal intra-alveolar root fracture in the middle third of a maxillary central incisor associated with an extrusive luxation of the coronal segment and its treatment in a 6-year-old gir...
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...
OBJECTIVE The accuracies of intraoral radiography (IOR), multidetector helical computerized tomography (MDHCT) at slice thicknesses 0.63 mm and 1.25 mm, and limited cone-beam computerized tomography (LCBCT) were compared for detection of horizontal tooth root fracture. STUDY DESIGN In 7 beagle dogs, 28 maxillary anterior teeth were used, of which 13 had artificially induced horizontal root fr...
