    Do patients' expectations influence their satisfaction with complete dentures?
    (University of the Western Cape, 2016) Ahmed, Rukshana; Khan, S
    Background: Most edentulous patients have expectations regarding complete dentures that are not only dependant on past experiences but also the information they received from others. These expectations may impact on the level of satisfaction the patient would have when receiving their complete dentures. When determining levels of satisfaction, factors such as comfort, speech, aesthetics, mastication, retention, fit / stability and occurrence of pain should be assessed. The dental student should be able to clinically apply theoretical knowledge to provide the patient with a stable and retentive denture that fulfils their expectations on function and aesthetics. Not much has been written regarding this link between patients' expectations and satisfaction with complete dentures at the University of the Western Cape, thus it warranted further investigation. Aim: The aim of this study was to determine whether patients' expectations influence their satisfaction with new complete dentures constructed by undergraduate dental students. Objectives:- 1. To determine the expectations of the edentulous patients prior to receiving new complete dentures. 2. To determine if patients’ expectations influences satisfaction with new complete dentures. 3. To investigate the influence of socio-demographic factors on patients' satisfaction wearing complete dentures. 4. To determine if the level of experience of the undergraduate student influences patient satisfaction. Methodology: This was an observational study using two questionnaires for data collection namely the Patient Expectation Questionnaire and the Oral Health Impact Profile- 20. Socio-demographic data was collected as part of the first questionnaire. Each participant was given an individual case number that corresponded on both questionnaires. This facilitated correlation between the expectations and satisfaction results of individual patients. Results: The age range for the majority of the patients was between 56-65 years. Females made up 72% of the sample with 85% of the sample of coloured ethnicity. Statistical analysis included reliability testing of the Patient Expectation Questionnaire and the Cronbach's Alpha of .773 was recorded, which indicates good reliability. Results following analysis of the Oral Health Impact Profile-20 showed high levels of satisfaction in most domains. The correlation between patients' expectations and satisfaction with new complete dentures was not proven using Pearson correlation. However, the comparison between the expectations questionnaire and Oral Health Impact Profile-20 frequency distribution showed positive results and most expectations of the patient were met or even exceeded for certain domains. Conclusion: Once analysis of both questionnaires was completed high levels of expectations were recorded and these expectations were met in most domains. Even though the statistical relationship between patient expectations and satisfaction was not proven, analysis of the questionnaires yielded positive results. No association was found between pre-treatment expectation and patient satisfaction with complete dentures. Some socio-demographic factors influenced patient satisfaction with complete dentures. High levels of patient satisfaction were recorded regardless of the clinical experience of the undergraduate dental student.

    Impact of Removable Partial Dental Prostheses on the Oral Health-Related Quality of Life of a South African Cohort with Varied Distributions of Missing Posterior Teeth
    (UWC, 2017) Khan, S
    Purpose: To determine the impact of removable partial dental prostheses on satisfying the daily functioning and quality of life (QoL) of adult patients with different distributions of missing posterior teeth. Materials and Methods: A cross-sectional interventional study was carried out on80 patients having variously distributed posteriorly shortened and interrupted arches. Treatment comprised provision of partial dentures by senior dental students, super-vised by senior clinical teachers who had knowledge of the potential benefits of the shortened dental arch (SDA) concept. The Oral Impacts on Daily Performance Index was completed before and 6 months after prosthetic treatment across groups comprising Kennedy Classes I, II, and III arches. Analysis included descriptive statistics and associations and comparisons between variables. Results: Mean age of patients was 57.4 years (SD=13.1), many were retired (72.2%),and a majority were females (60%). Most patients lived in urban areas (95%), and were largely unemployed (63.3%). At pre-treatment, only 31.3% of patients reported having good dental health and satisfaction with their current oral state, while 82.5% said they had a great need for treatment. The negative oral impacts that were most frequently experienced were those of eating (67.5%), smiling (50%), and being emotionally disturbed (63.8%). Post-treatment, 76.3% indicated good oral health and satisfaction with no significant differences between the 3 Kennedy groups. Any further negative impacts were reported mostly for Kennedy Classes I and II. Conclusions: Overall, significant reductions of negative impacts were observed following treatment with dentures, across the 3 Kennedy groups, with respect to improved function, satisfaction, and oral health-related QoL. The findings confirm the reliance by partially dentate patients in all 3 Kennedy groups on dentures for improved oral health, although the possible benefits of the SDA concept as an alternative treatment option was not specifically explored. Evidence from several sources recommends that reduced or interrupted dentitions should be categorized according to their ability to ensure satisfactory oral function.1-4Studieson oral function suggest that oral health related quality of life (OHRQoL) can be related to the presence of nine or more pairs of anterior and posterior occluding teeth,1,2,5andthat anything less than this negatively affects patient satisfaction and OHRQoL.1,2,5-7Generalizability of these results cannot be assumed, as contexts differ considerably regarding cultural and socioeconomic circumstances, which in turn have been shown to impact OHRQoL and patientsatisfaction.5,7Normative and perceived needs regarding the functional adequacy of partial edentulism, including reduced posterior dentitions, differ,2,8,9and thus assessments for prosthetic re-placement vary widely. In general, normative assessments of treatment needs, especially in older, partially dentate adults, exceed the perceived needs of the patients themselves.

    Outcomes of mandibular Kennedy Class I and II prosthetic rehabilitation - an observational study
    (University of the Western Cape, 2020) Chamoko, Joanna; Khan, S
    Tooth loss due to caries, periodontal diseases and trauma is sometimes unavoidable.¹ The World Health Organization (WHO) guidelines indicate that the highest prevalence of partial edentulism occurs between the ages 35-44 years2 and that 12.6% of that sector of the adult population was completely edentulous.2 However, according to the South Africa Demographic and Health Survey (SADHS), 23% of adults aged between 35-44 years were completely edentulous.3 Many South Africans must therefore be partially edentulous. The patterns of tooth loss do vary amongst different populations,4 and various studies have attempted to investigate the link between tooth loss and the different socio-economic factors between communities.
