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 ...
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.
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 ...
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 ...
Influence of variations in ceramic thickness and bonding substrate on the fracture resistance of lithium disilicate restorations
(University of the Western Cape, 2017)
Restorative dentistry aims to replace lost or damaged tooth structure with
durable and life-like alternatives. To accommodate the inherent limitations and weakness of
the restorative materials, preparation techniques ...
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 ...
