__________________________________________________________________________________________ Purpose: Evaluation the rate of bacterial colonization of the genital tract among a large group of Polish women and the relationship between the types of bacteria from the cervical canal of pregnant women and preterm delivery. Materials and methods: 1084 pregnant women were taken swab from the cervical ca...

background & importance: disc herniation is defined as the prolapsed of material disc into the spinal canal. if the disc fragment is free in spinal canal, it is called sequestration disc fragment. occasionally, alteration in sequestration disc fragment makes the diagnosis of the disc herniation, challenging. case presentation: we reviewed a rare case of the cervical sequestrated disc herniation...

STUDY DESIGN Retrospective Cross-Sectional Study OBJECTIVE.: Identify the pathoanatomical features of the cervical spine associated with congenital stenosis SUMMARY OF BACKGROUND DATA.: Congenital cervical stenosis (CCS) describes a patient with a decreased spinal canal diameter at multiple levels of the cervical spine in the absence of degenerative changes. Despite recognition of CCS throughou...

BACKGROUND AND PURPOSE Upper cervical spinal canal dimension may have a role in abnormal CSF dynamics in patients with Chiari I malformation. We attempted to measure spinal canal tapering from anteroposterior spinal canal dimensions in patients with Chiari I. MATERIALS AND METHODS Twenty-one patients with Chiari I malformation, including 12 with syringomyelia and 7 patients with IS were ident...

objective: one of the principle purposes of root canal obturation is to obtain hermetic sealing of the root canal system. according to the development of technology, many materials are now used in root canal filling. an in vitro dye leakage study was performed to evaluate the apical sealability of white-colored mineral trioxide aggregate (wmta) and gray-colored portland cement (gpc) when used a...

We treated 12 patients with multilevel stenosis of the cervical canal after spondylosis or ossification of the posterior longitudinal ligament by an expansive open-door laminoplasty, stabilised by using an anchor system. The preoperative sagittal diameter of the canal was 9.8 mm(+/-2.2) which was increased to 16.1 mm(+/-2.9) after surgery. The mean expansion ratio of the canal was 64% (42 to 10...

Aims The primary goals of endodontic treatment are to debride and disinfect the root canal space to the greatest possible extent, and to seal the canals as effectively as possible, aiming to establish or maintain healthy periapical tissues. Although initial root canal therapy has been shown to be a predictable procedure with a high degree of success, failure can occur after treatment. Lack of h...

UNLABELLED The search for new instruments to promote an appropriate cervical preparation has led to the development of new rotary instruments such as TripleGates. However, to the best of the authors' knowledge, there is no study evaluating TripleGates effect on the "risk zone" of mandibular molars. OBJECTIVES The aim of this study was to evaluate the effects of a crown-down sequence of Gates-...
