Dentine permeability and cytotoxicity of a dentine bonding agent
(University of the Western Cape, 2006)
The objectives of this study were to create an in vitro situation which closest resembled the clinical situation by inclusion of human dentine discs at a specified anatomic location as barrier and evaluating if comparable ...
Mechanical and handling properties of light-cured acrylic resin custom tray material
(University of the Western Cape, 2007)
Both light-cured (LC) and chemically-cured (CC) acrylic resin custom tray materials are used at the Oral Health Centre, Faculty of Dentistry, University of the Western Cape. At present, the CC acrylic is the standard for ...
The effect of dentine-bonding agents on the microleakage of provisional crowns
(University of the Western Cape, 2005)
The use of provisional acrylic crowns is common practice with prosthodontic treatment. Provisional crowns are prone to marginal leakage and poor retention due to weak interim cements. The aim of this study was to assess ...
Surface hardness of different shades and types of resin composite cured with a high power led light curing unit
(University of the Western Cape, 2006)
Light-emitting diode (LED) curing lights were introduced to the dental market promising a higher curing efficiency than halogen-based lights. The earlier generation curing lights, however, proved not to be as effective as ...
An in vitro study of microleakage and surface microhardness of nanocomposite restorative materials
(University of the Western Cape, 2005)
The demand for posterior aesthetic restorations has dramatically increased in recent years. Several new materials have been developed with improved aesthetic, adhesive and mechanical properties. However, microleakage ...
The retentive strength of bonded amalgam restorations
(University of the Western Cape, 2005)
Amalgam bonding agents have been shown to enhance retention of amalgam restorations by mechanical means. However, recent studies showed that the use o glass ionomer cements and resin cements as lining and bonding materials ...
The sealing ability of mineral trioxide aggregate (MTA) used as retrograde filling agent in roots with filling and unfilled root canals: an in vitro comparative study
(University of the Western Cape, 2007)
The aim of this study was to determine whether the presence or absences of the root canal seal had any influence on the retrograde sealing ability of MTA (mineral trioxide aggregate).
