Traumatic injuries of the face often involve root fractures especially in anterior teeth. The prognosis and the treatment of the root fracture depend on the extent of the fracture line, general health and patient compliance. This case report outlines a new conservative trial treatment modality to stabilize the maxillary central incisors with horizontal root fracture on the cervical to middle th...

  Objective: Diagnosis of vertical root fractures (VRFs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. Despite Cone Beam Computed Tomography (CBCT) has significantly enhanced image quality compared to digital radiography (DR) which aid the diagnosis, artifacts has remained as a problem in VRF detection . ...

  Background and Aims: Diagnosis of vertical root fractures often poses a clinical dilemma. Diagnosis of VRF in intraoral radiographs, except in cases where the beam is perpendicular to the direction of fracture is difficult. Misdiagnosis often leads to wrong decisions about the design of teeth future treatment plan. The aim of this study was to determine the diagnostic accuracy of reverse cont...

reconstructive techniques through dynamic and static tests. Forty human anterior teeth were divided into 4 groups (n=10): GNW (non-weakened) – root restored with glass fiber post (GFP), GW – weakened root restored with GFP, GDA weakened root restored with direct anatomic GFP, and GIA weakened root restored with indirect anatomic GFP. The teeth were endodontically treated considering that experi...

This case report describes the management of an oblique crown-root fracture of maxillary left central incisor. After removal of the fractured fragment, endodontic treatment, the remaining tooth was provisionally restored. The tooth was then orthodontically extruded by 3 mm to raise the defect supraginigivally. Periondonal fibres were cut with a surgical blade. A metallic screw type post was ins...

INTRODUCTION Comparing the epidemiology of fractures originating in the cervical and apical regions may help to understand the causes and risk of a vertical root fracture. We aimed to determine the frequency of vertical root fractures in different fracture sites and how the fracture site relates to fracture direction and post length. METHODS Teeth diagnosed with a vertical root fracture were ...

OBJECTIVE To evaluate the impact of the type of root canal preparation, intraradicular post and mechanical cycling on the fracture strength of roots. MATERIAL AND METHODS eighty human single rooted teeth were divided into 8 groups according to the instruments used for root canal preparation (manual or rotary instruments), the type of intraradicular post (fiber posts- FRC and cast post and cor...

Finite element analysis (FEA) is an engineering method for the numerical analysis of complex structures based on their material properties. It is used to determine the distribution of stress when a structure is subjected to force. Recently, FEA has been employed in endodontic. Endodontic diseases, such as pulpits or periradicular periodontitis, often require root canal therapy. During or after ...

background: reinforcement of root canals obturated with resilon was reported by several investigators, but no studies reported the reinforcement of overtly fl ared root canals obturated with resilon material. the aim of this study was to investigate the fracture resistance of overtly fl ared root canals fi lled with resilon as compared to similar root canals fi lled with gutta-percha (gp). mate...

Objective To compare periapical radiograph (PR) and cone-beam computed tomography (CBCT) in the diagnosis of alveolar and root fractures. Material and Methods Sixty incisor teeth (20 higid and 40 with root fracture) from dogs were inserted in 60 anterior alveolar sockets (40 higid and 20 with alveolar fracture) of 15 macerated canine maxillae. Each fractured socket had a root fractured tooth ...
