Erosion process of polycarboxylate cements in organic acids.
The amounts of Zn and Mg eluted from the zinc polycarboxylate cement into acetic, lactic and citric acids increased with an increase in the formation constant of the acid-Zn or -Mg complexes. The erosion process consisted of two processes, namely, dissolution of the unreacted cement powder and decomposition of the matrix. The matrix was remarkably eroded by 0.01M citric acid which formed stable...
متن کاملErosion process of a glass ionomer cement in organic acids.
Erosion of a glass ionomer cement in acetic (AA), lactic (LA), citric (CA) and hydrochloric acids (HA) was investigated by means of chemical analysis, SEM observation and infrared (IR) spectroscopy. The larger stability constants of the complex between the acid anions and Al or Ca, or the lower the pH of the acid solutions, the more Al, Ca, Na, Si and F were leached. SEM observation revealed th...

The mechanical properties of polycarboxylate cements containing 20 massO/o of fbur kinds of aluminoborate whiskers with ditTercnt fiber lengths and diameters were eva]uated. Bending strength of the cements inereased with increase in fiber length, whereby the strength ol' the cement with the longest fiber was about two times greater than that ef whisker-free cement, The diametral tensile strengt...

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولEffects of polycarboxylate and glass ionomer cements on stainless steel crown retention.
Retentive properties of three dental cements were tested using stainless steel crowns Fitted to extracted third molar teeth. No significant difference was Found between the overall mean retentive Forces of the polycarboxylate cement and the two glass ionomer cements. Mechanical retention of the crowns was not a Factor in the overall retentive value. Few studies have investigated the retention o...
