مقدمه: روشهای متفاوتی برای درمان مینای دمینرالیزه وجود دارد ولی در مورد موثر بودن پروسه ی بلیچینگ بر دندان های دارای لکه سفید اطلاعات زیادی در دسترس نیست. لذا هدف از این تحقیق بررسی مقایسه ای تأثیر بلیچینگ در مطب با کمک لیزر و بلیچینگ در منزل بر روی مینای سالم و مینای دمینرالیزه بود. روش کار: تعداد 120دندان انسیزور گاوی انتخاب و به طور تصادفی به چهار گروه تقسیم شدند. سطح دندان ها با پامیس به م...
Quantum random number generators (QRNGs) are a burgeoning technology used for variety of applications, including modern security and encryption systems. Typical methods exploit an entropy source combined with extraction or bit generation circuit in order to produce string. In integrated designs, there is often little modeling analytical description the source, extraction, post-processing provid...
Dry socket is considered as the most common complication following tooth extraction. The incidence of dry around 3% for all routine extractions and might surpass 30% impacted mandibular third molars. It accompanied by a partially or totally disintegrated blood clot within alveolar socket, with without halitosis. mainly manifested severe irradiating pain that starts 1 to 4 days after dental extr...
UNLABELLED Retrograde cerebral perfusion (RCP) potentially delivers metabolic substrate to the brain during surgery using hypothermic circulatory arrest (HCA). Serial measurements of O2 extraction ratio (OER), PCO2, and pH from the RCP inflow and outflow were used to determine the time course for O2 delivery in 28 adults undergoing aortic reconstruction using HCA with RCP. HCA was instituted af...
Visual search for an element defined by the conjunction of its colour and orientation has previously been shown to be a serial processing task since reaction times increase linearly with the number of distractor elements used in the display. Evidence is presented that there are parallel processing constituents to this serial search. Processing time depended on the ratio of the number of the two...

شایع ترین دندان های نهفته, مولر های سوم فک بالا وپایین وبعد کانین های فک بالا وپرمولر های فک پایین میباشند.مولر های سوم آخرین دندان هایی هستند که میرویند وبنابراین به احتمال زیاد فضای کافی برای رویش ندارند و نهفته باقی می مانند.دندان مولر سوم نهفته به دلایل ایجاد عوارض مشکل ساز گوناگون باید جراحی واز محیط دهان خارج گردند.از جمله این عوارض علاوه بر مشکلات پریودنتال سبب فشار از سوی مولر سوم نهفته...
introduction: impaction of third molars can be associated with a number of sequelae, each requiring a different type of treatment. the purpose of this study was to assess the changes in the position of lower third molars following extraction and non-extraction orthodontic treatments. methods: pre- and post-treatment panoramic radiographs of 26 class i malocclusion patients (4 male and 22 female...
extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (elms) was investigated using lix 84i as the carrier. measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the elm extraction processes. the effect of operating parameters such as feed ph, initial feed concentration, and treat ...
