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 ...
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 ...
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 ...
Heat transmission along the surface of dental implant
(University of the Western Cape, 2009)
Objectives: Temperature changes along an implant body have not been widely studied. The objectives of this in vitro study were (i) to establish if the temperature of the abutment influences the temperature of the implant ...
Prevalence of signs and symptoms of temporomandibular joint dysfunction in subjects with different occlusions using the Helkimo index
(University of the Western Cape, 2005)
The controversy surrounding the role of malocclusion and orthodontic treatment in temporomandibular joint (TMJ) dysfunction led to this study. The purpose of this study was to establish the prevalence and compare the status ...
The taper of clinical crown preparations done by dental students and dentists in two African countries: a comparative analysis
(University of the Western Cape, 2004)
Crowns have been used since the 5th century AD to improve both the form and function of teeth in the mouth. A great proportion of the total expenditure on dental care is spent on the provision and replacement of crowns and ...
Comparison of time taken and breakage of six different endodontic systems to prepare molar teeth
(University of the Western Cape, 2006)
The purpose of this study was to determine duration time, breakage and apical displacement, whilst using six different endodontic filing systems to prepare molar teeth. A total of 96 molar teeth were used in the study, ...
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 ...
Influence of a bleaching agent on stained direct composite resins
(University of the Western Cape, 2008)
Despite the phenomenal strides in research of dental resin composites regarding their physical
and mechanical properties, discolouration, either intrinsic or extrinsic still remains a major
drawback and is one of the ...
A comparative study to evaluate patient satisfaction with conventional dentures and implant retained overdentures
(University of the Western Cape, 2006)
The edentulous jaw is a common feature in elderly patients that had lost their teeth during life due to local reasons such as poor oral hygiene and dental caries as well as periodontal disease. Hence these patients are the ...
