Analysis of coronal discoloration from commonly used obturation materials
Elkhazin, Mohamed M. A. (University of the Western Cape, 2007)The objective of this study was to assess coronal discoloration due to four commonly used endodontic sealers with gutta-percha, using spectrophotometric analysis. Extracted human teeth were obturated with the experimental ... -
A comparative study to evaluate patient satisfaction with conventional dentures and implant retained overdentures
Al-Makki, Amjad (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 ... -
Comparison of time taken and breakage of six different endodontic systems to prepare molar teeth
Brittain, Roger (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, ... -
Dentine permeability and cytotoxicity of a dentine bonding agent
Du Bois, Alexander Hermann (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 ... -
Do complete dentures improve the quality of life of patients?
Adam, Razia Zulfikar (University of the Western Cape, 2006)Few studies have documented the impact of complete dentures on patients’ oral health-related quality of life. Objectives: The purpose of this study was to investigate the relationship between gender, age, socioeconomic ... -
Heat transmission along the surface of dental implant
Patel, Zaheed (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 ... -
The in vitro effect of a tooth bleaching agent on coffee and wine stained teeth
Malyi, Emil C. (University of the Western Cape, 2008)Summary: Aim: The aim of this laboratory study is to assess the efficacy of a tooth bleaching agent by evaluating the degree of color change with the use of a spectrophotometer and not by the usual subjective, visual ... -
An in vitro study of microleakage and surface microhardness of nanocomposite restorative materials
Majeed, Abdul (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
Wanjau, Caroline (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 ... -
Mechanical and handling properties of light-cured acrylic resin custom tray material
Khan, Saadika B. (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 ... -
Photoelastic stress patterns produced by the angled distal implants in the All-on-Four concept
Begg, Tasneem (University of the Western Cape, 2006)The purpose of this study was to investigate the stress produced around the angled distal implants under simulated occlusal loading in the All-on-Fourª concept by means of two-dimensional photoelastic stress models. -
Prevalence of signs and symptoms of temporomandibular joint dysfunction in subjects with different occlusions using the Helkimo index
Kalanzi, Dunstan (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 retentive strength of bonded amalgam restorations
Banna, Trinadha Rao (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 ... -
Surface hardness of different shades and types of resin composite cured with a high power led light curing unit
Lodhi, Tariq Abbas (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 taper of clinical crown preparations done by dental students and dentists in two African countries: a comparative analysis
Enechi, Theophilus Chukwuemeka (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 ...
