    Differences in functional outcomes for adult patients with prosthodontically-treated and -untreated shortened dental arches : a systematic review
    (Public Library of Science, 2014) Khan, Saadika; Musekiwa, Alfred; Chikte, Usuf; Omar, Ridwaan
    This review examined differences in functional outcomes and patient satisfaction when shortened dental arches are left untreated compared to their restoration to complete arch lengths with different prosthodontic interventions. Methods: A protocol was developed according to the criteria for a systematic review. All relevant databases were searched to identify appropriate clinical trials regardless of language or publication status. Predetermined eligibility criteria were applied, trial quality assessed and data extracted for each study. Relevant outcomes assessed were: functioning ability, patient satisfaction and harmful effects on oral structures. Results: Searches yielded 101 articles: 81 from electronic databases and 20 from reference lists of retrieved articles (PEARLing searches). Sixty-nine citations were assessed for eligibility after removing 32 duplicate records. After reading titles and abstracts, a total of 41 records were excluded and the full-texts of the remaining 28 records were read. Only 21 records were included for the SR because 7 records were excluded after reading the full-text reports. These 21 records report the outcomes of four randomized controlled trials (RCTs) and one non-randomized clinical trial (CT) which were pre-specified and used for this review. No on-going studies were found and no eligible studies were excluded for failure to report the reviewer’s pre-specified outcomes. Outcomes were reported in the retrieved 21 articles. A narrative explanation of the prespecified outcomes is reported for the 3 comparison groups (which were based on the different interventions used for the individual clinical trials). The shortened dental arch as a treatment option is encouraging in terms of functioning, patient satisfaction and cost-effectiveness. By using only high quality studies it was expected that the results would be more reliable when making conclusions and recommendations, but some of the included studies had to be downgraded due to methodological errors.

    From classroom teaching to clinical practice: experiences of senior dental students regarding the shortened dental arch concept
    (Journal of Dental Education, 2014) Khan, Saadika; Chikte, Usuf; Omar, Ridwaan
    This study explored the barriers to a meaningful translation of didactic classroom instruction to clinical practice, using the shortened dental arch (SDA) concept as a case study. A combination of survey and individual and group interviews (a mixed- methods approach) was used to collect data related to the SDA. The cohort consisted of senior dental students and their clinical teachers at the University of the Western Cape, South Africa. The response rates were 100 percent for the students (n=73) and 78 percent for the clinical teachers (n=16). Triangulation was employed to eliminate bias and strengthen the reliability of the re- search. In the quantitative analysis, most students (81 percent) reported having heard about the SDA concept at the university, but their responses revealed an absence of clinical implementation. The students agreed that patients can function adequately with an SDA and agreed with presenting it as a treatment option to patients. In the qualitative analysis, a “change in the clinical require- ments,” “being empowered by exposing them to SDA literature,” and “change in health policies” were recommended measures to increase implementation of the SDA approach clinically. The students were positive about the SDA as a treatment option, but the lack of adequate knowledge and encouragement in clinical implementation was a hindrance to its use.

    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
    (Wiley, 2017) Khan, Saadika; Chikte, Usuf; Omar, Ridwaan
    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 on 80 patients having variously distributed posteriorly shortened and interrupted arches. Treatment comprised provision of partial dentures by senior dental students, supervised 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.

    Outcomes with a posterior reduced dental arch: a randomised controlled trial
    (Wiley, 2017) Khan, Saadika; Chikte, Usuf; Omar, Ridwaan
    OBJECTIVE: To compare function, patient satisfaction and quality of life of patients with a posterior reduced mandibular arch with those who had all missing teeth replaced with removable partial dentures. METHODS: Patients with at least 3 and not more than 6 posterior occluding pairs of teeth were enrolled sequentially and randomized into one of two treatment groups: a denture and no denture group. A research assistant allocated interventions; concealment was ensured using opaque-sealed envelopes. Analysis of data was performed in stages, adding samples of 10 incrementally, and stopping when the relevant statistical tests indicated a clear conclusion as judged by the power set at 80% or above. Study outcomes included patient satisfaction, function and survival of remaining teeth at 3 and 12 months post-intervention, using a visual analogue scale and the Oral Impacts on Daily Performance) Statistical analysis was performed by the ‘intention-to-treat’ principle. RESULTS: Age range of included patients was 23-55 years (mean=42.3; SD=9.2), with 78% being females. Most patients (70%) belonged to the low- or no-income group. Nine patients left the study, for different reasons. Primary outcomes for the denture group: 10% of the patients were not satisfied and 20% were unhappy with their function; for the no-denture group: 85% of the patients (with 15% having left the study) were satisfied with both their function and their non-denture status. CONCLUSION: Patients with posterior reduced mandibular dental arches reported greater perceived satisfaction, function and quality of life compared to those who had received a cobalt-chrome clasp-retained partial removable prosthesis.

    An Overview of Systematic Reviews Related to Aspects of the Shortened Dental Arch and Its Variants in Adults.
    (International Journal of Prosthodontics, 2017-07) Khan, Saadika; Chikte, Usuf ME; Omar, Ridwaan
    Aim To conduct an overview of systematic reviews (SRs) related to aspects of the shortened dental arch (SDA) and its variants, and critically appraise the methodological quality of the included SRs using the AMSTAR checklist. Methods A comprehensive computerized search and hand-searching of reference lists were conducted for SRs related SDAs to identify publications from 2000-2016. All authors and a research assistant independently screened the results of the electronic searches using an eligibility form and extracted information using a specially designed pre-piloted data extraction form. An 11-question AMSTAR checklist was completed for each included SR. Disputes were resolved by discussion between all researchers and results collated and interpreted. Results For the period 2007-2016, the search yielded 9 SRs incorporating 228 related articles. The research questions for each SR differed but were related to SDAs, thus the included articles were similar across SRs. Characteristics such as aims/objectives, study outcomes and conclusions of the 9 included SRs were compared. The AMSTAR evaluation indicated that 5 out of 9 studies were of a high quality (used a rigorous methodology) and the remaining 4 were of medium quality. All 9 SRs provided designs and characteristics of included studies. None of the SRs assessed publication bias. Conclusion Seven out of the nine SRs drew positive conclusions regarding the SDA concept, finding it functionally sound although some suggested that more high quality primary studies are still needed. The AMSTAR calculation indicated that most included SRs had an acceptable methodological quality, emphasizing the reliability of their results.

    Perceptions regarding the shortened dental arch among dental practitioners in the Western Cape Province, South Africa
    (South African Dental Association, 2012) Khan, Saadika; Chikte, Usuf; Omar, Ridwaan
    AIMS and OBJECTIVES: This survey was conducted to de-termine the knowledge of and opinions related to the short-ened dental arch (SDA), among dentists in the Western Cape Province, South Africa. METHODS: The study sample included two consecutive groups, drawn by a process of randomisation from the reg-istered dentist population that included general dentists, specialists, those who had emigrated and retired dentists. A self-administered questionnaire was mailed, e-mailed and/or faxed to those selected. Reminders were either e-mailed or made by telephone over a period of six months. RESULTS: A final sample of 84 respondents with a mean age of 43 years (SD=11.9) was obtained. This represented a response rate of 23% (n= 84) from the final working sample (n=368), derived from the target group (n=618) originally con-tacted. All participants completed an informed consent form in which confidentiality was assured. Several respondents (40%) said they had heard about the SDA while at university, which would be in line with the age range of respondents in relation to introduction of the concept into dental curri-cula. As many as 62% had never read any research articles related to the concept which could partly account for the low response rate. The majority (86%) felt that patients can function with a SDA and that they would recommend ac-ceptance to their patients. CONCLUSION: Respondents know of the potential benefit that the SDA may have for their patients and see it as a viable alternative treatment option for the partially dentate patient, even though their level of current knowledge of the subject must be considered questionable.
