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 ... -
Oral health of institutionalised children in a place of safety in Moshi, Tanzania
(University of the Western Cape, 2008)The aim of the study was to analyze oral health status(dental caries, periodontal conditions, fluorosis and malocclusion) of institutionalised children at Amani and Mkombozi street children homes in Moshi town, Tanzania. ... -
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 ... -
Clinical evaluation of shade improvement after in-office vital bleaching
(University of the Western Cape, 2010)Tooth discoloration has increased the demand by patients to pursue aesthetic treatment options. Bleaching is considered a conservative approach in performing an aesthetic treatment for discolored teeth; however colour ... -

An in vitro study of post-restorative bleaching: effect on microleakage
(University of the Western Cape, 2010)Aim and Objectives: To assess the effect of bleaching on the marginal integrity of Class V composite resin restorations. To determine the effect of a 6% hydrogen peroxide over the counter and a 38% hydrogen peroxide in-office ... -
A Clinical Study to Determine the Factors That May Influence Results in Non-Surgical Endodontic Retreatments
(University of the Western Cape, 2010)When faced with a failing or failed root treatment, the dentist must decide whether the tooth can be retreated and saved or extracted. The dentist's decision to retreat is often based on the x-ray presenting a failing root ... -
Push out strengths of a double tapered post system with 3 different cements
(University of the Western Cape, 2012)The aim of the study was to determine which of the three resin cements would produce the highest debond stress values with a double-tapered fibre post system. In the past, conventional parallel- sided prefabricated or ... -
The effect of temperature on the linear dimensional stability of elastomers
(University of the Western Cape, 2012)Sometimes, dental impressions need to be transported to distant laboratories. It has been reported that the temperature in a vehicle can reach up to 66C when the outdoor temperature is 38C. These temperatures may be ... -
The influence of mixing ratio on the fatigue behaviour of fibre reinforced polymers
(University of the Western Cape, 2013)Statement of the problem: Fibre reinforcement of polymethyl methacrylate (PMMA) denture base material is known to improve the strength, as well as the fatigue behavior, of the material. The powder liquid (P/L) ratio of ... -
Colour comparison of two composite materials to natural tooth structure: an in vitro study
(University of the Western Cape, 2013)This in vitro study compares the ability of two composite materials Filtek Supreme XTE™ (3M, ESPE) and CeramX™ Duo (Dentsply) against extracted tooth structure using the modern two layering concept. Fifty six extracted ... -
Comparison of retentive properties of two attachment systems in mandibular overdentures - an in vitro study
(2013)Aim: The aim of this study is to test and compare the retentive properties of two types of attachments i.e. Locator® and OT equator in a mandibular overdenture placed over 2 implants. -
Volumetric change due to polymerization in dental resins as measured with an electronic mercury dilatometer
(University of the Western Cape, 2014)To determine the total volumetric change and the relative speed of shrinkage of bulk fill flowable composites during polymerization. The volumetric change that occur during the polymerization of dental composite restorations ... -
Volumetric change due to polymerization in dental resins as measured with an electronic mercury dilatometer
(University of the Western Cape, 2014)Objectives: To determine the total volumetric change and the relative speed of shrinkage of bulk fill flowable composites during polymerization. Background: The volumetric change that occur during the polymerization of ... -
Water sorption and solubility of resin filled composites
(University of the Western Cape, 2015)Resin filled dental composite materials has been introduced into dental practice since mid-1960s as an aesthetic restorative material for anterior teeth (Bowen, 1962 cited in Peutzfeldt, 1997). Since then, they have undergone ... -
Micro-hardness and depth of cure of dental bulk-fill composites
(University of the Western Cape, 2015)Resin composite is one of the most commonly used materials in restorative dentistry. However, it has undergone continuous developments like changes in the fillers and initiators. One such improvement is the new bulk-fill ... -
Do patients' expectations influence their satisfaction with complete dentures?
(University of the Western Cape, 2016)Background: Most edentulous patients have expectations regarding complete dentures that are not only dependant on past experiences but also the information they received from others. These expectations may impact on the ... -
An in-vitro evaluation of repair protocols applied to composite resin
(University of the Western Cape, 2016)The shift towards minimally invasive dentistry has meant that dental practitioners are now undertaking procedures that are conservative and preserve as much of the existing tooth structure as possible. Repairing composite ... -
Evaluation of dentine damage after rotary NiTi preparation
(University of the Western Cape, 2016)NiTi rotary instruments have shape memory and are highly flexible and super-elastic. These properties of the metal alloy allows for ease of root canal preparation to ultimately result in a root canal preparation that has ... -
