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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
