Intra-radicular loss of tooth structure in endodontically treated teeth poses a challenge. Available methods for treatment are cast post-core, intra-radicular resin reinforcement using composite resin followed by placement of prefabricated metal/fibre post (glass or carbon).This study is an attempt to investigate the validity of treatment of such teeth using above methods and evaluate which pos...

This study evaluated the influence of alveolar bone level on the fracture resistance of root restored with post and core. Forty-eight extracted human mandibular premolars were divided into six groups. Cast posts and cores were cemented (MN8 and MP8) or resin cores were built up with fiber posts and composite resin (FN8, FP8, FN4, and FP4). Post length was 8 mm (MN8, MP8, FN8, and FP8) or 4 mm (...

one of most challenging problems in neuroradiology is differentiation lesions in brain and another challenging problems is post op. or post radiation/post chemotherapy changes vs recurrence /remnant. on this lecture i am going to show you many cases that on the basis of new technique such as swi, pwi, mrs, cine mri, dti and tractography we can achieve the final diagnosis.

PURPOSE The influence of the modified process in the fiber-reinforced post and resin core foundation treatment on the fracture resistance and failure pattern of premolar was tested in this study. MATERIALS AND METHODS Thirty-six human mandibular premolars were divided into 4 groups (n = 9). In group DCT, the quartz fibre post (D.T. Light-post) was cemented with resin cement (DUO-LINK) and a c...

Coronal rehabilitation of a severely damaged teeth is a challenge for clinician. The Endocrown is indicated for restoration of severely damaged molar, which requires specific restoration technique. This therapy promotes the stability and retention of the indirect restoration, without the need of a cast metal core or reconstruction with intracanal post, thereby reducing the treatment time. The m...

Teeth that have been endodontically treated often have little coronal tooth tissue remaining and, as such, require a post to retain the core and restoration, and need to be restored by crowns1,5,9. Metal posts are most commonly used due to their favourable physical properties and excellent biocompatibility4,8. With recent advances in ceramic technology, the all-ceramic crown has become more pop...

[Purpose] The purpose of this study was to examine the effects of the core muscle release technique on correction of lumbar deformation and alleviation of low back pain. [Subjects] Ninety patients diagnosed with lumbar deformation and low back pain participated in this study. [Methods] The participants were divided into three groups according to method of treatment. The first group was treated ...

From a selection of four kinds of post and core systems, including a fiber post and composite resin core, the purpose of this study was to determine the most effective system for the restoration of endodontically treated teeth with 0 mm of coronal tooth structure. For experimental abutment teeth, typical human maxillary central incisor teeth were modeled using bovine mandibular incisor teeth. B...
