Clinical evaluation of shade improvement after in-office vital bleaching
Salem, Yousef (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 ... -
A comparative study to evaluate patient satisfaction with conventional dentures and implant retained overdentures
Al-Makki, Amjad (University of the Western Cape, 2006)The edentulous jaw is a common feature in elderly patients that had lost their teeth during life due to local reasons such as poor oral hygiene and dental caries as well as periodontal disease. Hence these patients are the ... -
Comparison of occlusal rest seat preparations to cast metal rests
Cassim, Shabir (University of the Western Cape, 2007)A well designed metal-based removable partial denture (MBRPD) is a cost-effective and a conservative method of rehabilitating a partially edentulous mouth. The MBRPD demands that the abbutment tooth provides support and/or ... -
Disinfection procedures: effects on the dimensional accuracy of Gypsum casts
Salih, Mayson (University of the Western Cape, 2007)The aim of the study was to assess the dimensional accuracy of Gypsum models following chemical disinfection of the impressions and to compare it with the accuracy of gypsum models exposed to microwave irradiation disinfection. ... -
The effect of storage time on dimensional accuracy of elastomeric impression materials
Osio, Mary A. (University of the Western Cape, 2008)Several factors play a role in stability of impressions made from elastomeric impression materials. These include; polymerization shrinkage, loss of by-products during condensation, thermal contraction from oral temperature ... -
The effect of thermal-cycling on the bond strength of a two step and single-step dentin bonding agent
Omer, Amir Isam (University of the Western Cape, 2010)The aim and objective of this study was to determine the bond strength of a twostep and a single-step dentin bonding agent and to determine the effect of repeated thermal-cycling from 50C and 550C on the bond strength ... -
The efficacy of rotary and manual instruments in root canal debridement
Madlabane, Duduzile (2009)It has been shown that the use of both manual and rotary instruments result in the formation of a smear layer and debris during root canal treatment. The amount that is formed depends on the type of instrumentation used ... -
The in vitro effect of a tooth bleaching agent on coffee and wine stained teeth
Malyi, Emil C. (University of the Western Cape, 2008)Summary: Aim: The aim of this laboratory study is to assess the efficacy of a tooth bleaching agent by evaluating the degree of color change with the use of a spectrophotometer and not by the usual subjective, visual ... -
An in vitro study of composite repair
Mohammed, Hesham (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
Majeed, Abdul (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
Manni, Hassan (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 assessing the color stability of different provisional crown and bridge restorative materials
Barbara, Ndagire (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
Elnour, Mutasim Hassan (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. -
Influence of a bleaching agent on stained direct composite resins
Wanjau, Caroline (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 ... -
Oral health and nutritional status of the children under five years, Queen Elizabeth II Hospital, Maseru, Lesotho
Linjewile-Marealle, Navoneiwa (University of the Western Cape, 2006)The aim of this study was to compare the oral health status between well and malnourished children under five years old attending Mother and Child Health clinic in Queen Elizabeth II Hospital in Maseru, Lesotho. -
Prevalence of signs and symptoms of temporomandibular joint dysfunction in subjects with different occlusions using the Helkimo index
Kalanzi, Dunstan (University of the Western Cape, 2005)The controversy surrounding the role of malocclusion and orthodontic treatment in temporomandibular joint (TMJ) dysfunction led to this study. The purpose of this study was to establish the prevalence and compare the status ... -
The retentive strength of bonded amalgam restorations
Banna, Rao T. (2005)The purpose of this in vitro study is to compare the relative retentive strength of conventional amalgam restorations and bonded amalgam restorations using resin adhesive, glass ionomer cements and resin cements. -
