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 ...
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 ...
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 ...
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.
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 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 ...
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 ...
Analysis of coronal discoloration from commonly used obturation materials
(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 ...
Dentine permeability and cytotoxicity of a dentine bonding agent
(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 ...
The effect of dentine-bonding agents on the microleakage of provisional crowns
(University of the Western Cape, 2005)
The use of provisional acrylic crowns is common practice with prosthodontic treatment. Provisional crowns are prone to marginal leakage and poor retention due to weak interim cements. The aim of this study was to assess ...
