“Childhood scoliosis is a common clinical entity with a number of different causes. In the majority of cases, the scoliosis is idiopathic, but it may be the manifestation of an occult spinal pathology. The clinical

history and examination may elicit certain worrying features such as pain, neurological symptoms or an atypical curve pattern. These findings should prompt advanced imaging, as early and accurate detection of an underlying cause allows optimal planning and timing of surgery and helps reduce associated Lazertinib risks. The most common occult pathologies detected by advanced imaging are Arnold Chiari malformations, syringohydromyelia and closed spinal dysraphism such as diastematomyelia. Advanced imaging techniques, in particular multiplanar MRI, are also increasingly requested in children with known congenital scoliosis associated with spinal dysraphism and developmental causes of scoliosis such as neurofibromatosis and Klippel Feil syndrome, as it allows superior delineation of the spinal column without the radiation risk. This review aims to examine the different imaging techniques currently used in the evaluation

of scoliosis and provide a pictorial summary of the more common causes and associations.”
“Cement-retained restorations allow for a conventional fixed partial denture approach to restoring dental implants. However, inadequate removal of excess cement at

the time of cementation may introduce a severe complication: cement-induced peri-implantitis. Radiopaque cements are more easily detected on radiographs and should improve the recognition of extravasated cement at the time of insertion. The purpose of this study was to evaluate the radiopacity of commercially available cements in vitro. Eighteen different cements commonly used for luting restorations see more to implants were tested at both 0.5-and 1.0-mm thicknesses. The cements examined were zinc oxide eugenol, zinc oxide, zinc polycarboxylate, zinc phosphate, resin-reinforced glass ionomer, urethane resin, resin, and composite resin. Two samples of each cement thickness underwent standardized radiography next to an aluminum step wedge as a reference. The mean grayscale value of each of the nine 1-mm steps in the step wedge were used as reference values and compared to each of the cement samples. Temp Bond Clear (resin), IMProv (urethane resin), Premier Implant Cement (resin), and Temrex NE (resin) were not radiographically detectable at either sample thickness. Cements containing zinc were the most detectable upon radiographic analysis. There are significant differences in the radiopacity of many commonly used cements.
