Item Oral health community engagement programs for rural communities: A scoping review(Public Library of Science, 2024) Nghayo, Hlulani Alloy; Palanyandi, Celeste Ellouise; Ramphoma, Khabiso Jemima; Maart, RonelThis scoping review aims to identify the available literature on oral health community engagement programs that have been developed to guide oral health care in rural communities and to summarize their outcomes. This review was conducted using the 5-stage scoping review framework outlined by Arksey and O’Malley. We conducted a literature search with defined eligibility criteria through electronic databases such as Science Direct, PubMed, ProQuest, Scopus, EBSCOhost, and Wiley Online; other well-established online scientific health and dental organizations such as the WHO, the fédération dentaire internationale of the World dental federation, the American dental association, and the South African dental association; and grey literature spanning the time interval from January 2012 to August 2023. The charted data were classified, analysed, and reported using descriptive and thematic analyses. A total of 19 records were included in the final review. These records were classified into four categories of interventions: community-based, school-based, integrated dental-based, and non-dental volunteer oral health programs. The findings imply that there is a growing appreciation for the significance of qualitative data in enhancing oral healthcare interventions and outcomes. Furthermore, the study showed that oral health strategies were successful in shaping the understanding and perception of oral health among children and mothers/caregivers, and in improving the oral health and quality of life of edentulous older adults and children living in rural communities.Item Patient satisfaction with health care providers in South Africa: The influences of race and socioeconomic status(Oxford University Press, 2005) Myburgh, Neil G.; Solanki, Geetesh C.; Smith, Matthew J.The first democratic government elected in South Africa in 1994 inherited huge inequalities in health status and health provision across all sections of the population. This study set out to assess, 4 years later, the influence of race and socioeconomic status (SES) on perceived quality of care from health care providers. A 1998 countrywide survey of 3820 households assessed many aspects of health care delivery, including levels of satisfaction with health care providers among different segments of South African society.Item Foetal alcohol syndrome: A cephalometric analysis of patients and controls(Oxford University Press, 2006) Naidoo, Sudeshni; Harris, Angela; Swanevelder, SonjaFoetal alcohol syndrome (FAS) consists of multi-system abnormalities and is caused by the excessive intake of alcohol during pregnancy. The teratogenic effect of alcohol on the human foetus has now been established beyond reasonable doubt and FAS is the most important human teratogenic condition known today. The purpose of this study was to analyse the craniofacial parameters of children with FAS and compare them with matched controls. Ninety children diagnosed with FAS (45 males, 45 females) and 90 controls were matched for age, gender, and social class. The mean age of the FAS children was 8.9 years with the controls slightly older at 9.1 years. This age difference was not signifi cant ( P = 0.34). A standard lateral cephalometric radiograph of each subject was taken. The radiographs were digitized for 20 linear and 17 angular measurements. These 37 variables were formulated to assess the size, shape, and relative position of three craniofacial complexes: (1) the cranial base, (2) midface, and (3) mandible. In addition, nine variables were computed to compare the soft tissue profi les. The study showed that measurements related to face height and mandibular size appear to be the most important features when distinguishing FAS children. Overall, the FAS children in the present study presented with vertically and horizontally underdeveloped maxillae, together with features of long face syndrome with large gonial angles and a short ramus in relation to total face height. There was also a tendency for the development of an anterior open bite, which appears to be compensated for by an increase in the vertical dimension of the anterior alveolar process to bring the incisor teeth into occlusion. The latter adaptation occurred mainly in the mandible.Item Correlative imaging and histopathology of a complicated sinonasal teratocarcinosarcoma(SA Journal of Radiology, 2023) van Zyl, Tineke; Leon, Janse van Rensburg; Opperman, Johan F; Naidoo, Komeela; Merven, MarcSinonasal teratocarcinosarcoma (SNTCS) is a highly malignant and rare tumour characterised by a complex admixture of teratomatous and carcinosarcomatous components. In the head and neck area, it almost exclusively occurs in the sinonasal cavities; however, rare instances of nasopharyngeal and oral cavity involvement have been reported, with fewer than 100 cases reported in the literature. Contribution: The contributed case involves the correlative CT, MRI and histopathology of a sinonasal teratocarcinosarcoma with intracranial involvementItem Evaluation of innovative polyvinyl alcohol/ alginate/ green palladium nanoparticles composite scaffolds: Effect on differentiated human dental pulp stem cells into osteoblasts(2023) Ismail, Enas; Mabrouk, Mostafa; Salem, Zeinab A.; AbuBakr, Nermeen; Beherei, HananThree-dimensional (3D) scaffolds are attracting great concern for bone tissue engineering applications. However, selecting an appropriate material with optimal physical, chemical, and mechanical properties is considered a great challenge. The green synthesis approach is essential to avoid the production of harmful by-products through textured construction, sustainable, and eco-friendly procedures. This work aimed at the implementa tion of natural green synthesized metallic nanoparticles for the development of composite scaffolds for dental applications. In this study, innovative hybrid scaffolds of polyvinyl alcohol/alginate (PVA/Alg) composite loaded with various concentrations of green palladium nanoparticles (Pd NPs) have been synthesized. Various char acteristic analysis techniques were used to investigate the synthesized composite scaffold’s properties. The SEM analysis revealed impressive microstructure of the synthesized scaffolds dependent on the Pd NPs concentration. The results confirmed the positive effect of Pd NPs doping on the sample stability over time. The synthesized scaffolds were characterized by the oriented lamellar porous structure. The results confirmed the shape stability, without pores breakdown during the drying process. The XRD analysis confirmed that doping with Pd NPs does not affect the crystallinity degree of the PVA/Alg hybrid scaffolds. The mechanical properties results (up to 50 MPa) confirmed the remarkable effect of Pd NPs doping and its concentration on the developed scaffolds. The MTT assay results showed that the incorporation of Pd NPs into the nanocomposite scaffolds is necessary for increasing cell viability. According to the SEM results, the scaffolds with Pd NPs provided the differentiated grown osteoblast cells with enough mechanical support and stability and the cells had a regular form and were highly dense. In conclusion, the synthesized composite scaffolds expressed suitable biodegradable, osteo conductive properties, and the ability to construct 3D structures for bone regeneration, making them a potential option for treating critical deficiencies of bone.Item “We Want to See Youth That Would Be Better People Than Us”: A Case Report on Addressing Adolescent Substance Use in Rural South Africa(International Journal of Environmental Research and Public Health, 2023) Wagner, L; David, Ifeolu; Majee, WilsonResearch suggests that substance use, particularly among adolescents may lead to increased illegal activities as well as physical and social health consequences. Around the world, communities, overburdened with adolescent and youth substance use, are finding ways to address this public health threat. Using a case study based on a focus group discussion with nine founding members, this paper reports on the case of Sibanye—a rural community coalition whose mission is to reduce the burden of adolescent substance use on families in rural South Africa. The focus group discussions were audio-recorded, transcribed verbatim, and analyzed using Nvivo 12. This work highlights the power of an engaged collective effort in addressing key community issues, even in rural areas of emerging economies where health and community infrastructure may be limited. The Sibanye coalition taps into its collective wealth of community knowledge to provide social contributions and aesthetics to help adolescents abstain from substance use and sexual risk behaviors. These activities offer adolescents safe places to meet each other, health education, and the ability to structure their free time meaningfully. Engaging community residents, particularly disadvantaged groups, should be central to any local and national strategies for promoting health and well-being.Item We are not Islands: The role of social support in the relationship between perceived stress during the COVID-19 pandemic and psychological distress(International Journal of Environmental Research and Public Health, 2023) Pretorius, Tyrone B.; Padmanabhanunni, Anita; Isaacs, Serena A.The COVID-19 pandemic precipitated an overall increase in the global prevalence of mental health disorders and psychological distress. However, against this backdrop, there was also evidence of adaptation and coping, which suggested the influence of protective factors. The current study aims to extend previous research on the role of protective factors by investigating the health-sustaining and mediating roles of resilience in the relationship between perceived vulnerability to disease, loneliness, and anxiety. Participants consisted of a convenience sample of schoolteachers (N = 355) who completed the Perceived Vulnerability to Disease Questionnaire, the short form of the Connor–Davidson Resilience Scale, the University of California, Los Angeles Loneliness Scale, and the trait scale of the Spielberger State-Trait Anxiety Scale, through an online link created with Google Forms. The results of path analysis indicated significant negative associations between resilience and both loneliness and anxiety. These results indicate the health-sustaining role of resilience. In addition, resilience mediated the relationships between germ aversion and perceived infectability, on the one hand, and loneliness and anxiety, on the other hand. The findings confirm that resilience can play a substantial role in counteracting the negative impact of the pandemic on mental health.Item Oral health practices and self-reported adverse effects of E-cigarette use among dental students in 11 countries: An online survey(BMC Oral Health, 2022) Khan, SaadikaObjectives E-cigarette use has become popular, particularly among the youth. Its use is associated with harmful general and oral health consequences. This survey aimed to assess self-reported oral hygiene practices, oral and general health events, and changes in physiological functions (including physical status, smell, taste, breathing, appetite, etc.) due to E-cigarette use among dental students. Methods This online, multicounty survey involved undergraduate dental students from 20 dental schools across 11 different countries. The questionnaire included demographic characteristics, E-cigarette practices, self-reported complaints, and associated physiological changes due to E-cigarette smoking. Data were descriptively presented as frequencies and percentages. A Chi-square test was used to assess the potential associations between the study group and sub-groups with the different factors. Statistical analysis was performed using SPSS at P < 0.05. Results Most respondents reported regular brushing of their teeth, whereas only 70% used additional oral hygiene aids. Reported frequencies of complaints ranged from as low as 3.3% for tongue inflammation to as high as 53.3% for headache, with significant differences between E-cigarette users and non-users. Compared to non-smokers, E-cigarette users reported significantly higher prevalence of dry mouth (33.1% vs. 23.4%; P < 0.001), black tongue (5.9% vs. 2.8%; P = 0.002), and heart palpitation (26.3%% vs. 22.8%; P = 0.001). Although two-thirds of the sample reported no change in their physiological functions, E-cigarette users reported significant improvement in their physiological functions compared to never smokers or tobacco users. Conclusion Dental students showed good oral hygiene practices, but E-cigarette users showed a higher prevalence of health complications.Item Comparison of a piezoelectric and a standard surgical handpiece in third molar surgery(UWC, 2019) Titinchi, F; Gopal, I; Morkel, JAim: The aim was to compare the use of a piezoelectric hand piece versus a standard surgical handpiece in removal of impacted third molars under general anaesthesia. Materials and methods: Thirty patients undergoing routine third molar removal were included in the study. Panoramic radiographs were used to assess the positioning of the impacted third molars. The patients were randomly subdivided and the split mouth technique was used in which each side (left or right) of the mouth was randomly assigned to two treatment groups. Hence each patient served as their own control. In one group, a piezoelectric handpiece was used, while a conventional handpiece was used for the second group. All aspects of preoperative care, general anaesthesia, surgery and post-operative care were standardised for the two groups. The following parameters were recorded; time of surgery, bleeding during surgery, post-operative swelling, post-operative pain, associated complications and post-operative nerve injury. Results: No statistically significant difference was found between the groups in terms of pain and swelling. There was less bleeding with the use of the piezoelectric device as compared with the standard surgical handpiece; however, the surgical time was longer. There were no reports of trauma to the lips or intra-oral soft tissue. There were two incidences (6.7%) of post-operative paraesthesia in the standard surgical handpiece group. Conclusions: The use of a piezoelectric device is an acceptable alternative to the standard surgical handpiece in third molar surgery. Its use is advocated in difficult cases especially where there is inferior alveolar nerve approximation.Item Frequency of four-dimensional oral health problems across dental fields - A comparative survey of Slovenian and international dentists(2021) Chantaracherd, Pathamas; Sekulić, Stella; John, Mike TObjectives: To compare the frequency of patients' oral health problems and prevention needs among Slovenian and international dentists with the aim to validate the four oral health-related quality of life (OHRQoL) dimensions across six clinical dental fields in all World Health Organization (WHO) regions. Methods: An anonymous electronic survey in the English language was designed using Qualtrics software. A probability sampling for Slovenia and a convenience sampling strategy for dentist recruitment was applied for 31 countries. Dentists engaged in six dental fields were asked to categorize their patients' oral health problems and prevention needs into the four OHRQoL dimensions (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact). Proportions of patients' problems and prevention needs were calculated together with the significance of Slovenian and international dentists' differences based on dental fields and WHO regions. Results: Dentists (n=1,580) from 32 countries completed the survey. There were 223 Slovenian dentists (females: 68%) with a mean age (SD) of 41 (10.6) years and 1,358 international dentists (females: 51%) with a mean age (SD) of 38 (10.4). Pain-related problems and prevention needs were the most prevalent among all six dental fields reported by dentists; Slovenian (37%) and 31 countries (45%). According to Cohen, differences between Slovenia, the broader European Region, and 31 countries were considered non-significant (<0.1). Conclusion: According to the dentists' responses, the frequency of patients' oral health problems and prevention needs are proportionate between Slovenia and 31 countries, regionally and globally. The four OHRQoL dimensions can be considered universal across all dental fields.Item Cost-effectiveness and efficacy of fluoride varnish for caries prevention in South African children: A cluster-randomized controlled community trial(Wiley, 2021) Effenberger, S; Greenwall, L; Cebula, MObjectives: This cluster-randomized controlled community trial aimed to assess the efficacy and costs of fluoride varnish (FV) application for caries prevention in a high-risk population in South Africa. Methods: 513 children aged 4–8 years from two schools in a township in South Africa were randomly allocated by class to the FV or Control (CO) groups. In addition to supervised toothbrushing with fluoridated toothpaste in both groups, FV was applied in 3-month intervals by trained local non-professional assistants. Intraoral examinations were conducted at baseline, 12, 21 and 24 months. Primary outcome was the increment of teeth with cavitated lesions (i.e. newly developed or progressed, formerly non-cavitated lesions), requiring restoration or extraction over the study period. Additionally, treatment and re-treatment costs were analyzed. Results: 513 children (d1-4mft 5.9 ± 4.3 (mean ± SD)) were randomly allocated to FV (n = 287) or CO (n = 226). 10.2% FV and CO teeth received or required a restoration; 3.9% FV and 4.1% CO teeth were extracted, without significant differences between groups. While FV generated high initial costs, follow-up costs were comparable in both groups, resulting in FV being significantly more expensive than CO (1667 ± 1055 ZAR vs. 950 ± 943 ZAR, p < .001). Conclusions: Regular FV application, in addition to daily supervised toothbrushing, had no significant caries-preventive effect and was not cost-effective in a primary school setting within a peri-urban, high-risk community in South Africa. Alternative interventions on community or public health level should be considered to reduce the caries burden in high-risk communities.Item Tutors use of semantic eaves as a teaching strategy to guide student learning: A case study(The future of education, 2019) Subethra, Pather; Vivienne, WilsonThis study investigated teaching and learning strategies, used by peer tutors in a Bachelor of Oral Health (BOH) tutorial class, to enhance active and engaged learning. This study was conducted on tutorial classes that were linked to a BOH high impact module which many students found challenging. Peer tutors who are senior students in the Faculty of Dentistry led the tutorial classes. Tutorial classes refer to small group teaching which allow for one-on-one interaction and increased student engagement with a peer tutor.Item Oral health care experiences of people living with HIV in Kwazulu-Natal and Western Cape, South Africa(Emerald Group Publishing Limited, 2015) Turton, Mervyn; Naidoo, SudeshniThe purpose of this paper is to ascertain the oral health experiences of people living with HIV/AIDS in the provinces of Kwazulu-Natal (KZN) and Western Cape (WC) in South Africa. Many studies have reported that people living with HIV have unmet needs for dental care and this study considered the various factors that affect the accessibility and utilisation of dental services as these factors are even more pertinent for the people living with HIV who have increased need for dental careItem 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, RidwaanThis 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.
