Root fracture is defined as a fracture involving the dentin, cementum, and pulp. Most fractures occur in the maxillary anterior teeth between the ages of 11 and 20 years old. The treatment for root fracture in permanent teeth involves the reduction and fixation of the displaced coronal segment. When signs of pulp necrosis or inflammatory root resorption are present, root canal therapy should be...

PURPOSE Preparation of a one-piece dental implant abutment is often needed to achieve a proper emergence profile for a definitive restoration. However, this procedure may compromise osseointegration through the production of heat. The aim of this study was to measure heat production during implant abutment preparation with different volumes of water irrigation using a one-piece implant system. ...

AIM To describe the management of external invasive resorption using mineral trioxide aggregate (MTA). SUMMARY External invasive root resorption may occur as a consequence of trauma, orthodontic treatment, intracoronal bleaching and surgical procedures, and may lead to the progressive and destructive loss of tooth structure. Depending on the extent of the resorptive process, different treatme...

introduction: coronal microleakage may significantly reduce the prognosis of endodontic treatment. temporary restorative materials have a crucial role in preventing the infection of root canals between and after endodontic treatment. this in vitro study was designed to evaluate the coronal microleakage of three temporary restorative materials used in endodontics: coltosol, cavisol and cina. mat...

The emergence and development of resin-based materials, such as resin composites adhesive systems, have shifted the restorative treatment anterior teeth with caries lesions and/or fractures. Thus, based on disadvantages indirect restorations, direct esthetic restorations are options even for exten sive loss hard tissues. This study aimed to describe discuss composite restoration performed solve...

Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described in this case enable practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissue...

Bilateral symmetry in vertebrates is imperfect and mild asymmetries are found in normal growth and development. However, abnormal development is often characterized by strong asymmetries. Coronal craniosynostosis, defined here as consisting of premature suture closure and a characteristic skull shape, is a complex trait. The premature fusion of the coronal suture can occur unilaterally associat...

OBJECTIVE When successive restorative procedures (e.g., porcelain veneers, interdental resin composite restorations, and endodontic treatment) are carried out on the same tooth, significant effects on crown flexure can be expected. METHOD AND MATERIALS Dentin-bonded porcelain veneers (experimental group) were assessed in vitro using functional and cyclic thermal loads. They were compared to n...

STUDY DESIGN This study is a retrospective review of the initial enrollment data from a prospective multicentered study of adult spinal deformity. OBJECTIVES The purpose of this study is to correlate radiographic measures of deformity with patient-based outcome measures in adult scoliosis. SUMMARY OF BACKGROUND DATA Prior studies of adult scoliosis have attempted to correlate radiographic a...
