AIM To report the intentional replantation of a maxillary central incisor with a crown-root fracture. SUMMARY An 11-year-old girl was referred to a paediatric clinic with an extensive crown-root fracture of the maxillary right central incisor (tooth 11) with pulp exposure. Radiographs revealed that tooth 11 had a periapical radiolucent lesion, which suggested pulpal necrosis. The treatment op...

This case report describes the management of an oblique crown-root fracture of maxillary left lateral 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...

To investigate the influence of post length and amount of remaining root tissue on the fracture resistance of roots restored with fibre posts relined with resin composite. Ninety upper canine teeth were divided into nine groups (n = 10). The post spaces were prepared resulting in different lengths, as follows: group 2/3, preparations with lengths of 10 mm; group 1/2, preparations with lengths o...

OBJECTIVES The aim of the present study was to investigate pulp survival following crown fracture with and without pulp exposure as well as with and without associated subluxation and in relation to stage of root development and type of enamel-dentine fracture. MATERIALS AND METHODS This study consisted of 83 patients with 116 crown fractured incisors without pulp exposure and 35 patients wit...

A most frustrating complication to root canal therapy is vertical root fracture (VRF) in an endodontically treated tooth. Prognosis most often is hopeless and differential diagnosis from other pathoses may be difficult at times. Nevertheless, proper diagnosis is critical to distinguish a fracture complication from clinical manifestations of periodontal and endodontic diseases. This review empha...

most of the earth's crust contains fluids, and fractures are common throughout the upper part. they exist at a wide range of scales from micro-fractures within grains to major faults and shear zones that traverse the crust. in this paper, the stress-dependent permeability in fractured rock masses have been investigated considering the effects of nonlinear normal deformation and shear dilation o...

Dental trauma is more common in young patients and its sequelae may impair the establishment and accomplishment of an adequate treatment plan. This paper reports a case of complicated crown-root fracture in a young adult that was treated using adhesive tooth fragment reattachment and orthodontic root extrusion. Considering the time elapsed to follow up, the fracture extension, the amount of rem...

Instrument fracture within the root canal during root canal treatment is an unwanted and frustrating complication. The fractured segment may hinder cleaning and shaping procedures with potential impact on prognosis of treatment. Fracture of endodontic instrument often results from incorrect use or overuse. If breakage occurs clinically, the patient should be informed of the incident and conside...

A longitudinal complicated crown-root fracture of an unerupted permanent incisor following trauma to primary teeth is reported. The development of the affected permanent tooth was not disturbed during a follow-up period of six years. Traumatic injuries to primary teeth can be transmitted to the permanent dentition because of the close relationship between the apices of primary teeth and the dev...

in this work, studies of underground gas storage (ugs) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. results showed that di...
