| dc.description.abstract | Individuals with unilateral cleft lip and palate (UCLP) require extensive multidisciplinary treatment in order to address the various features of their condition. It is important to establish reliable baseline data so that orthodontic and surgical treatment outcomes can be assessed and compared to those of other cleft palate centres in South Africa as well as internationally. The aim of this study was to establish correlations between the skeletal jaw relationship measured on lateral cephalograms and the Goslon Yardstick measurement scores for dental arch relationship (DAR) of orthodontic study models for a group of individuals with UCLP in the Western Cape. The results of this study provide a description of the craniofacial morphology, dentoalveolar characteristics, and correlations between the two for this group of individuals before they received orthodontic treatment and secondary alveolar bone graft (SABG). This study also gives a result of the differential growth between the maxilla and the mandible in these individuals. A convenience sample of 49 records of individuals with UCLP who presented for treatment at the Red Cross War Memorial Children’s Hospital (RCWMCH) and Tygerberg Oral Health Centre (TOHC) was collected retrospectively from the archives of the Department of Orthodontics, Faculty of Dentistry, UWC. The age, gender and side of cleft for the individuals with UCLP in the sample was recorded on an Excel spreadsheet. Fourteen cephalometric angles were measured on cephalograms by two observers and the Goslon Yardstick scores were determined on the plaster study models by three observers. Descriptive and inferential statistics were carried out using SAS. Inter- and intraobserver reliability was determined using the Cohen’s Weighted Kappa statistic and the concordance correlation coefficient (CCC) using a mixed model. Cephalometric measurements and the Goslon Yardstick scores were compared by regression analysis to determine the correlations between the cephalometric sagittal skeletal parameters and the Goslon scores. | |
