The accuracy of non-radiographic mixed dentition predictive methods used for the diagnosis of space discrepancies in orthodontic patients in the mixed dentition phase in Africa: A systematic review of diagnostic test accuracy
(University of Western Cape, 2021)Orthodontic space analysis is a critical component into informing diagnosis and leading to targeted interceptive treatment planning in the mixed dentition stage of tooth development. Accurate and reliable space analysis ... -
Accuracy of Orthodontic bracket adaptation
(University of the Western Cape, 2019)Background: A close marginal adaptation between the tooth and the bracket base is important since it provides the space for the adhesive. In order to withstand and resist the orthodontic forces exerted as well as everyday ... -
Accuracy of orthodontic digital study models
(University of the Western Cape, 2012)Background: Plaster study models are routinely used in an Orthodontic practice. With the recent introduction of digital models, an alternative is now available, whereby three dimensional images of models can be analyzed ... -
The accuracy of visualized treatment objectives in bimaxillary protrusion patients
(University of the Western Cape, 2008)The aim of this research project was to assess the accuracy of four different types of VTO [Steyn (1979), Jacobson and Sadowsky (1980), Ricketts (1982) and Holdaway (1984)], in predicting the final result of the incisor ... -
Analysis of dental anomalies in patients with unilateral cleft lip and palate at academic hospitals in the western cape, South Africa
(University of the Western Cape, 2023)The aim of this study is to determine the type and frequency of dental anomalies associated with patients with non-syndromic complete unilateral cleft lip and palate receiving treatment at Academic hospitals (UWC Oral ... -
Applicability of tooth size predictions in the mixed dentition analysis in a Kenyan sample
(University of the Western Cape, 2004)Mixed denticentition space analysis forms a critical aspect of early orthodo However, the applicability of these methods in other ethnic groups has been varied and questionable. The aim of this study is to evaluate the ... -
Assessment of Dental Arch Relationships in a sample of patients with Unilateral Cleft Lip and Palate in the Western Cape, South Africa
(University of the Western Cape, 2024)Unilateral cleft lip and palate (UCLP) is a specific form of orofacial cleft (OFC) that accounts for 23% of those born with clefts. In the Eastern Cape, Free State and Northern Cape provinces of South Africa (SA), the ... -
Assessment of tooth movement in the maxilla during orthodontic treatment using digital recording of orthodontic study model surface contours
(University of the Western Cape, 2006)The aim of this project was to measure changes in dimension of the first three primary rugae and to evaluate tooth movement in the maxilla during orthodontic treatment in patients treated with and without premolar extractions. -
Bond strength of metal orthodontic brackets to all ceramic crowns
(University of the Western Cape, 2016)Aim: The aim of this study was to evaluate, in-vitro, the shear bond strength (SBS) and the resultant failure pattern after debonding of metal orthodontic brackets bonded with TransbondTM XT adhesive resin cement and RelyXTM ... -
A cephalometric and dental analysis of treatment outcomes of unilateral cleft lip and palate children treated at the Red Cross children's hospital
(University of the Western Cape, 2000)This study was a cephalometric and dental investigation of the treatment outcomes of UCLP children treated at the Red Cross Children's Hospital (RCCH) with respect to craniofacial morphology and dental arch relationship. ... -
A Cephalometric Comparison of Class II Extraction Cases Treated with Tip-Edge and Edgewise Techniques
(University of the Western Cape, 2012)The Tip-Edge and edgewise techniques are the main techniques that are mostly used in orthodontics, and are applicable to the treatment of any type of malocclusion from the most simple to the most complex. The edgewise ... -
Changes in arch dimensions after extraction and non-extraction orthodontic treatment
(University of the Western Cape, 2008)The aim of this study was to determine whether there are changes in the interdental arch widths and arch lengths of the mandibular and maxillary arches during nonextraction and extraction orthodontic treatment. The records ... -
Chemical aspects of human plaque and enamel
(University of the Western Cape, 1982)The ideal conditions for the use of hydrazinium sulphate as a reducing agent to determine phosphorus in dental plaque were investigated. When this method was compared to the tin (II) chloride (Kuttner and Cohen, 1927) and ... -
