Nanoparticles as advanced treatment modalities to disinfect the root canal system
(University of the Western Cape, 2019)Persistent root canal pathogens are one of the main causes of endodontic treatment failure. These pathogens are usually isolated in areas within the root canals that are inaccessible to mechanical instrumentation, chemical ... -
Outcomes of mandibular Kennedy class I and II prosthetic rehabilitation
(University of the Western Cape, 2018)Loss of teeth has a negative impact on appearance, nutrition, function and diet. Rehabilitation of tooth loss is an important function of oral health care. Rehabilitation with removable prosthesis of mandibular terminal ... -
An in-vitro evaluation of the physical properties of a new bulk-fill composite
(University of the Western Cape, 2017)Dental composite is a synthetic resin that is used as a tooth coloured restorative material in dentistry. It became the material of choice in the dental field due to its superiority in strength and aesthetics (Garcia et ... -
An in-vitro study of a modified bioactive orthodontic cement
(University of the Western Cape, 2017)Introduction: Demineralization of the enamel surface adjacent to bonded orthodontic brackets during treatment is an ongoing drawback, especially when manifested as white spot lesions. Enamel demineralization is initiated ... -
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 ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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. -
An in-vitro study assessing the effect of smear layer on root canal microleakage
(2008)The aim of this study was to compare the sealing ability of AH Plus sealer to the canal wall in the presence and absence of the smear layer. -
An in-vitro study assessing the color stability of different provisional crown and bridge restorative materials
(2006)The aim of this study was to investigate the color stability of two provisional restorative materials used in crown and bridge cases upon exposure to different tea staining solutions and to evaluate the effectiveness of a ... -
The in vitro effect of a tooth bleaching agent on coffee and wine stained teeth
