An In vitro Study of Bacterial Leakage of a Novel Implant Abutment Interface
(University of the Western Cape, 2020)Background: The two-stage implant system has proven to be a successful technique in replacing missing teeth (Nascimento et al., 2008). Nevertheless, the presence of micro-gaps that could entrap microbes at the implant-abutment ... -
An in vitro study of composite repair
(2007)The aim of this study is to investigate the repair bond strength of composite resin following micromechanical and chemical means of retention in improving the repair of composite resin specimens. -
An in vitro study of microleakage and surface microhardness of nanocomposite restorative materials
(University of the Western Cape, 2005)The demand for posterior aesthetic restorations has dramatically increased in recent years. Several new materials have been developed with improved aesthetic, adhesive and mechanical properties. However, microleakage ... -
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 study of the microleakage of a compomer (polyacid modified resin composite) bonded to enamel and dentine with different bonding systems and the effect of saliva contamination there of.
(Stellenbosch University, 2002)Restorative systems classified as polyacid modified composite resins, or compomers, have appeared on the market. An example of this is Dyract AP. Dyract AP must be used with the Prime & Bond NT bonding system. Prime & ... -
An in vitro study of the properties of GICs with bioactive biomaterial modification
(University of the Western Cape, 2019)The fluoride release and chemical adherence to tooth structure remain the most desirable features of glass ionomer restorative cements (GICs). Although the physical properties for multi-surface restorations are well-defined, ... -
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 ... -
An in-vitro evaluation of the efficacy of oral devices to remove dental biofilm from three prosthodontic materials
(University of the Western Cape, 2019)Introduction: The evolution of Dentistry witnessed an increase in fixed prostheses as opposed to removable ones. Zirconia (ZrO2) and Lithium disilicate (LDS) are becoming the material of choice in implant or tooth retained ... -
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 ... -
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 of the fatigue resistance and structural integrity of different aesthetic posts.
(University of the Western Cape, 2024)Aim: The aim of the study was to assess and determine the fatigue resistance of different fiber posts and to observe their ultrastructures through scanning electron microscopy (SEM). Objectives: To assess and compare the ... -
The incidence of dental anomalies in a Qatari population sample
(University of Western Cape, 2021)There is no data specific to the Qatari population on the incidence of dental anomalies. The aim of this study was to investigate the incidence of dental anomalies in a Qatari population sample of patients between 6 and ... -
Incidence of plasmablastic lymphoma in HIV positive and negative patients at a tertiary hospital in South Africa (2005-2017)
(University of the Western Cape, 2018)The aim of the study was to investigate and describe the incidence of Plasmablastic Lymphoma (PBL) diagnosed at the Divisions of Anatomical Pathology and Haematopathology at Tygerberg Hospital from 2005 to 2017, and to ... -
Incidence, trends of prevalence and pathological spectrum of head and neck lymphomas at national health laboratory services- Tygerberg
(University of the Western Cape, 2007)MChD (Oral Pathology) minithesis, Department of Oral and Maxillofacial Pathology, Faculty of Dentistry, University of Western Cape Among malignant lesions, lymphoma ranks second only to squamous cell carcinoma in frequency ... -
Incidental calcifications s of the head and neck on CBCT scans
(University of the Western Cape, 2022)One of the most notable additions to the dental imaging armamentarium is the introduction of cone-beam computed tomography (CBCT) scanning in general dental practices. The multi-planar functionality of CBCT allows for ... -
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 ... -
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 ... -
Influence of orthodontic caregiver behaviour on the perceived satisfaction of patients during orthodontic treatment.
(University of the Western Cape, 2014)Influence of orthodontic caregiver behaviour on the perceived satisfaction of patients during orthodontic treatment. Dr. F.J. du Raan M.Sc. (Orthodontics) thesis, Department of Orthodontics, University of the Western Cape. ... -
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 ... -
The influence on masticatory performance of jaw movements, chewing side preference, occlusal contacf area, muscle activity and jaw tremor
(University of the Western Cape, 1996)The primary function of the jaws and teeth in mammals is chewing and swallowing. In man there are additional functions of speech, non-verbal communication and cosmetic appeal. Chewing is a complex operation requiring both ...
