An in vitro study of the microleakage of a compomer (polyacid modified resin composite) bonded to enamel and dentine with different bonding systems and the effect of saliva contamination there of.
(Stellenbosch University, 2002)Restorative systems classified as polyacid modified composite resins, or compomers, have appeared on the market. An example of this is Dyract AP. Dyract AP must be used with the Prime & Bond NT bonding system. Prime & ... -
An in vitro study of the properties of GICs with bioactive biomaterial modification
(University of the Western Cape, 2019)The fluoride release and chemical adherence to tooth structure remain the most desirable features of glass ionomer restorative cements (GICs). Although the physical properties for multi-surface restorations are well-defined, ... -
An in vitro study on the immunotoxicity of sewage effluents discharged into the Eerste River-Kuils river water catchment system
(2008)"The aim of the study was to use in vitro human whole blood cultures to screen the water samples collected from the Eerste/Plankenbrug river system for cytotoxicity and inflammatory activity and for the first time investigate ... -
An in vitro study on the immunotoxicity of South African beer
(University of the Western Cape, 2008)Traditionally brewed beers are of cultural and economic importance to many African nations. The presence of mycotoxins in African beer is a topic that needs to be addressed, since most African countries have a climate of ... -
