Clinical, radiographic, diagnostic and cephalometric features of pycnodysostosis in comparison with Turkish cephalometric norms: A case report

Pycnodysostosis is a rare genetic disorder and was first described in 1962 by Maroteaux and Lamy. The incidence of this anomaly is estimated to be 1.7 per 1 million births. The principal characteristics of this disorder are short stature, prominent eyes with blue sclera, beaked nose, cranial dysplasia, exposed fontanelles and cranial sutures, clavicular dysplasia, total/partial dysplasia of the terminal phalanges, obtused mandibular gonial angle, and generally increased bone density. Some features of pycnodysostosis are similar to osteopetrosis and cleidocranial dysostosis. Therefore, it must be distinguished from osteopetrosis and cleidocranial dysostosis in order to diagnose it in individuals of a younger age. The aims of this case report were to show the clinical, radiographic, and diagnostic features, as well as the cephalometric characteristics of pycnodysostosis in comparison with Turkish cephalometric norms

Antibacterial Effects of Several Current Orthodontic Materials against Streptococcus mutans

KAMAK, HASAN/0000-0003-1910-3694WOS: 000322424100010PubMed: 23757904The aim of this study was to examine the antibacterial effect of several current orthodontic materials against a certain oral bacterium. The antibacterial activities of six orthodontic composite resins (Transbond LR, Light Cure Retainer (LCR), Light Bond, System 1+, Kurasper E Transbond XT adhesive), two orthodontic bonding materials (Transbond XT primer and System 1+ activator) and two glass ionomer cements (GIC) [Multicure Glass Ionomer and Ketac Cem WC] were evaluated against Streptococcus mutans. The hard materials were put into the Teflon mould. The liquid materials were put on a paper disc. All materials were handled under aseptic conditions and placed on agar culture plates. All plates were incubated at 5% CO2 and 37 degrees C for 48 hours. The bacterial growth inhibition zones including the diameter of the sample were measured in millimetres. As a result of this study, the multicure GIC showed the highest antibacterial effectiveness, but no inhibition zones were noted for ketac cem GIC. The light bond adhesive of the Reliance orthodontic bonding system produced high antibacterial effect against S mutans, while the Reliance composite (LCR) did not show any antibacterial effect (p < 0.05). Both composite and primer of the transbond XT system demonstrated significant antibacterial effect against the test bacterium when compared to transbond LR (p < 0.05). Among the materials tested, kurasper F, Ormco system 1+ and system 1+ activator showed slight or no inhibitory effect against the test bacterium in this study. In patients who have relatively high salivary levels of Streptococci mutans before treatment, the multicure GIG, the Reliance light bond adhesive, and transbond XT system which had high level antibacterial properties could be applied

Метод комплексної оцінки захищеності озброєння та військової техніки від керованих ракет з інфрачервоним контуром наведення

The method of complex estimation of security of marine propelling facilities with the infra-red contour  of aiming from the guided rockets has been  considered. For determination of index of security combination of method of analysis of hierarchies and method of the group taking into account of arguments is used.Рассмотрен метод комплексной оценки защищенности вооружения и военной техники от управляемых ракет с инфракрасным контуром наведения. Для определения показателя защищенности использована комбинация методов анализа иерархий и группового учета аргументов.Розглянуто метод комплексної оцінки захищеності озброєння та військової техніки від керованих ракет з інфрачервоним контуром наведення. Для визначення показника захищеності використано комбінацію методів аналізу ієрархій та групового урахування аргументів
