Dental trauma can lead to a wide range of injuries of which crown and root fractures are examples. Crown-root fractures often need complex treatment planning. This case report describes the use of MTA in the multidisciplinary management of a patient with a horizontally fractured central incisor and luxation in a different central incisor. A 42-year-old(More)
BACKGROUND Numb chin syndrome is an uncommon but well-recognized symptom in medical oncology. This condition can be related to metastatic neurological manifestation of malignancy, often with no clinically visible pathology. About 1% of oral cancers, which are located in the soft tissues and jaws, are metastases of primary tumors located elsewhere in the(More)
The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented(More)
INTRODUCTION Artifacts in cone-beam computed tomographic (CBCT) imaging may compromise radiodiagnosis. Obturation materials for endodontic treatment may present with variable material density and thus also cause distinct artifact expression. The aim of this study was to assess the volume distortion artifact of root canal sealers using CBCT devices and(More)
Root resorption is loss of dental hard tissue as a result of clastic activities. The dental hard tissue of permanent teeth does not normally undergo resorption, except in cases of inflammation or trauma. However, there are rare cases of tooth resorption of an unknown cause, known as "idiopathic root resorption." This report would discuss a rare case of(More)
The aim of this study was to evaluate and compare the presence of voids in oval root canals filled with different root canal sealers (EndoSequence BC Sealer, Smartpaste bio, ActiV GP) and to compare those with root canals filled with AH Plus sealer using micro-CT. In total, 40 freshly extracted human single-root maxillary premolars were used. Specimens(More)
BACKGROUND We evaluated and compared the effects of different NiTi rotary systems--ProTaper Next and New One Shape--on the volume of dentin removed, canal transportation, and canal curvature in extracted human teeth using CBCT scanning with different voxel sizes. METHODS Fifty extracted human maxillary first molars with mesiobuccal canal curvature(More)
This study used micro-CT to compare three obturation techniques with respect to void occurrence in canals filled with bioceramic sealer. Thirty extracted first mandibular premolars were prepared with a ProTaper Universal system and randomly allocated to three groups. Canals were obturated with gutta-percha and bioceramic root canal sealer, using either(More)
OBJECTIVE The objective of this study was to compare the coronal microleakage intraorifice barrier materials, called CoroSeal (CS), fissur sealant (FS), flowable composite FC, and policarboksilate cement (PC), by using the computerized fluid filtration method. MATERIALS AND METHODS Fifty freshly extracted, single-canal human maxillary central teeth were(More)
Microorganisms in untreated or overlooked root canals can cause endodontic failure or infection and inflammation. Therefore, clinicians should familiarize themselves with patient’s root canal anatomy and morphology. The objective of this retrospective study was to analyze and characterize mandibular root canal morphology using cone beam computed tomography(More)
