The role of community health workers in promoting oral health at school settings: A scoping review.

OBJECTIVES: The scoping review aimed to examine the literature on the role of Community Health Workers (CHW) in oral health interventions within school settings. The objectives were to identify the characteristics of school oral health interventions where CHWs played a role; and to assess the outcomes derived from CHW participation in school oral health. METHODS: The scoping review was guided by the Levac et al (2010) framework. Articles selected for this review included all forms of study designs and gray literature. The search strategy included CHW and other non-dental personnel providing oral health activities within schools and the outcomes of these interventions from 1995. Databases included Pubmed, ProQuest, Scopus and EBSCO Host. RESULTS: There were eleven (n = 11) peer reviewed articles included. Only one study in this review related to CHW involvement in school oral health settings. The remaining involved teachers (n = 4), peer learners (n = 3) or a combination of both (n = 3). Characteristics of the interventions ranged from oral health screenings, education, supervised brushing, and community engagements. Three outcomes emerged; widening access to oral health services, acceptability of non-oral health personnel and learners in promoting oral health and improvement of oral health self-care. CONCLUSIONS: The review brought to light the benefits of utilizing non-dental personnel such as teachers and peer learners in augmenting staff capacity for school oral health interventions. In addition, the findings highlighted the need to further research on the feasibility and acceptability of integrating CHW in school oral health settings.

Oral health-related quality of life among people living with HIV and HIV-negative adults in Kigali, Rwanda: a comparative cross-sectional study.

BACKGROUND: Assessing health-related quality of life has become integral to people living with HIV (PLHIV) follow-up. However, there is a lack of data regarding the impact of oral health on quality of life, known as Oral health-related quality of life (OHRQoL) among PLHIV compared to HIV-negative individuals in Rwanda. AIM: The study aimed to assess OHRQoL among PLHIV compared to HIV-negative counterparts in Kigali, Rwanda. METHODS: The Oral Health Impact Profile short version (OHIP-14) questionnaire was interviewer-administered to 200 PLHIV and 200 HIV-negative adults (≥ 18 years old) at an HIV clinic of Kigali Teaching Hospital (CHUK). Socio-demographic characteristics, including age, sex, occupation, and socioeconomic status (SES) of participants, were collected using a survey questionnaire. A 4-point Likert scale was used to assess the frequency of oral impacts for all 14 items within 7 domains of the OHIP tool. The descriptive statistics were used to see frequencies and percentages of OHRQoL among PLHIV and HIV-negative persons, respectively. The Chi-square test was used to determine the association of OHRQoL with caries (DMFT) and periodontal disease (CPITN) among PLHIV compared to HIV-negative individuals. RESULTS: The results revealed a higher prevalence of PLHIV with poor OHRQoL than HIV-negative individuals in 5 domains and almost all items of OHIP-14 except for the OHIP 3 (found it uncomfortable to eat any foods because of problems with teeth or mouth) and OHIP-14 (being totally unable to function because of problems with teeth or mouth). The findings showed statistically significant results (p ≤ 0.05) for the OHIP1 item "trouble pronouncing any word," with a prevalence of 2.5% (n = 11) and 2.25% (n = 9) in PLHIV and HIV-negative, respectively. Also, PLHIV had a significantly higher prevalence, 2.75% (n = 11) for the OHIP 13 item "life not satisfying due to teeth and mouth problems compared to HIV-negative individuals 2% (8) p ≤ 0.05. Moreover, dental caries was significantly associated with poor OHRQoL among PLHIV and HIV-negative adults and for all 14 items of the OHIP tool. Periodontal disease was not significantly associated with OHRQoL among PLHIV and HIV-negative adults. CONCLUSION: This study revealed poor OHRQoL among PLHIV compared to HIV-negative adults. There is a need for further longitudinal studies to investigate the OHRQoL in Rwanda, especially among PLHIV. It is essential to include oral health care as one of the components of the medical health care programs for PLHIV in Rwanda.

Oral health knowledge, attitude and oral hygiene practices among adults in Rwanda

Introduction: oral diseases (OD), commonly dental caries and periodontitis are a major public health problem. Poor oral hygiene has been associated with OD, causing tooth loss, which leads to disability and compromised patients' oral health. In Rwanda, OD is among the leading causes of morbidity at the health center level. Therefore, the purpose of this study was to assess the knowledge, attitude, and oral health practices among adult participants in Rwanda Methods: a descriptive cross-sectional study was done among participants attending public health facilities in Nyarugenge District, Rwanda. Participants were interviewed using a structured questionnaire. The data were analyzed using frequency distribution, percentage distribution, and bivariate and multivariate logistic regression at a 5% significant level. Results: among 426 participants who were interviewed, 39.44% (n=168) were 18-27 years old and the majority, 61.5% (n=262) were female. Poor oral health knowledge was found in 42% (n=179) of the participants, whilst 12.44% (n=53) showed poor oral health attitudes, and 67.37% (n=287) were found to have poor oral health practice. Participants with a high school level of education were more likely to have better oral health knowledge and the results were statistically significant aOR: 1.79, 95% CI 1.14; 2.82; p = 0.011 Conclusion: the findings of our study showed that almost half of the participants had poor oral health knowledge. Oral health attitude and oral hygiene practices were also lacking. There is a need to enhance oral health education in this community to improve their oral health knowledge, attitudes, and practices.

Validation of the Child-Oral-Health-Impact-Profile among adolescents in Johannesburg: A cross-sectional study.

BACKGROUND:  Oral health-related quality of life (OHRQol) is described as the effect of oral conditions on the overall functioning and well-being of individuals. AIM:  This study sought to determine the validity of a modified-child oral health impact profile (M-COHIP) among adolescents living with the human immunodeficiency virus (HIV) infection (ALHIV) and HIV-undiagnosed adolescents and establish the factors influencing OHRQoL among adolescents in central Johannesburg. SETTING:  Schools and HIV wellness centre in central Johannesburg. METHODS:  An interviewer-administered questionnaire was applied, followed by an oral examination. RESULTS:  A total of 504 adolescents were included in the study. The overall mean decayed teeth for permanent dentition was 1.6 (standard deviation [s.d.]: 1.99) and caries prevalence was 62.2% (n = 309). The tool's Cronbach's alpha was 0.88. The item-rest correlations were from 0.6 to 0.85 for all items. The initial exploratory factor analysis explained 76% of the total variance. The overall M-COHIP score was 59.6 (18.2). The overall modified-COHIP scores for those not in care (schools) were higher [62.88] than those of ALHIV. The poor M-COHIP scores were associated with reporting toothache, having active decay, poor oral health-self-rating, and being selected from the school site (p  0.005). CONCLUSION:  The validation study supports the use of the tool as a reliable and valid measure of OHRQoL. Future research can investigate the extent to which the tool is effective in measuring treatment outcomes and patient satisfaction.Contribution: The validated tool will be beneficial in the African context for programme assessments and overall measure of quality-of-life impacts from oral conditions.

Exploring reasons why South African dental therapists are leaving their profession: A theory-informed qualitative study.

BACKGROUND: Dental therapy is a category of mid-level oral health professional that was introduced to address inequities in oral health service provision in South Africa within a constrained human resource for health context. However, low numbers of registered dental therapists and attrition threaten this strategy. AIM: This study explored reasons for this attrition, building on the Hertzberg Two-Factor Theory. METHODS: Through a qualitative exploratory study design, in-depth interviews were conducted with former dental therapists to explore their reasons for leaving the profession. They were recruited using snowball sampling. All interviews were audio recorded, transcribed verbatim, and coded in NVIVO12. A team of researchers applied thematic analysis to agree on themes and sub-themes, guided by Hertzberg's ideas of intrinsic and extrinsic factors. FINDINGS: All 14 former dental therapists interviewed expressed their passion for the profession, even though their motivations to join the profession varied. Many of their reasons for leaving aligned with extrinsic and intrinsic factors defined in Hertzberg's Two-Factor Theory. However, they also spoke about a desire for a professional identity that was recognized and respected within the oral health profession, health system, and communities. This is a novel study contribution. CONCLUSION: Dental therapist attrition in South Africa is mainly caused by job dissatisfaction and motivation issues resulting from health system level factors. While the Hertzberg Two-Factor Theory helped identify extrinsic and intrinsic factors at an individual level, we used the Human Resources for Health System Development Analytical Framework to identify solutions for dental therapist production, deployment, and retention. Addressing these issues will enhance retention and accessibility to oral health services in the country.

Prevalence of dental caries and associated risk factors among People Living with HIV/AIDS and HIV uninfected adults at an HIV clinic in Kigali, Rwanda.

BACKGROUND: Dental caries is among the most frequent oral conditions in People Living with HIV/AIDS (PLWHA). There is a lack of baseline information on dental caries prevalence and associated risk factors among PLWHA in comparison to HIV uninfected people in Rwanda. OBJECTIVE: This study was conducted to determine the prevalence of dental caries and associated risk factors among PLWHA and HIV uninfected adults at an HIV clinic of Kigali Teaching Hospital (CHUK) in Kigali, Rwanda. METHODS: A comparative cross-sectional study was conducted among 200 PLWHA and 200 HIV uninfected adults aged 18 years and above attending an HIV clinic of CHUK. An oral examination was performed by a calibrated examiner. Dental caries were assessed using the WHO Decayed (D), Missing (M), and Filled Teeth (F) index (DMFT). Descriptive statistics, Chi-square, t-tests, and multiple binary logistic regression were used to analyze data. RESULTS: Overall, a higher prevalence (50.5%) of PLWHA had experienced dental caries (DMFT>0) compared to HIV uninfected counterparts (40.5%) (p = 0.045). The prevalence of Decayed teeth (D) was also higher (23.5%) among PLWHA compared to HIV uninfected persons (13.6%) (p = 0.011). The Mean(SD) DMFT scores among PLWHA and HIV uninfected participants were 2.28 (3.68) and 1.29 (2.21) respectively (p = 0.001). After performing multiple binary logistic regression analysis, the predictors of dental caries in PLWHA were being female (OR = 2.33; 95%CI = 1.14-4.75), frequent dental visits (OR = 4.50; 95% CI = 1.46-13.86) and detectable RNA viral load (OR = 4.50; 95% CI = 1.46-13.86). In HIV uninfected participants, the middle age range (36-45 years), and frequent dental visits were significantly associated with dental caries (OR = 6.61; 95%CI = 2.14-20.37) and (OR = 3.42; 95%CI: 1.337-8.760) respectively. CONCLUSION: The prevalence of dental caries was higher in PLWHA than in HIV uninfected counterparts. The reported higher prevalence of caries in PLWHA was associated with being female, detectable viral load, and frequent dental visits. Therefore, there is a need for effective oral health interventions specific to PLWHA in Rwanda to raise awareness of the risk of dental caries and provide preventive oral health services among this population. To ensure timely oral health care amongPLWHA, there is a need for an effort from policymakers and other stakeholders to integrate oral health care services within the HIV treatment program in Rwanda.

Experiences of doctoral students enrolled in a research fellowship program to support doctoral training in Africa (2014 to 2018): The Consortium for Advanced Research Training in Africa odyssey.

BACKGROUND: The Consortium for Advanced Research Training in Africa (CARTA) aims to transform higher education in Africa. One of its main thrusts is supporting promising university faculty (fellows) to obtain high quality doctoral training. CARTA offers fellows robust support which includes funding of their attendance at Joint Advanced Seminars (JASes) throughout the doctoral training period. An evaluation is critical in improving program outcomes. In this study; we, CARTA fellows who attended the fourth JAS in 2018, appraised the CARTA program from our perspective, specifically focusing on the organization of the program and its influence on the fellows' individual and institutional development. METHODS: Exploratory Qualitative Study Design was used and data was obtained from three focus group discussions among the fellows in March 2018. The data were analyzed using thematic approach within the framework of good practice elements in doctoral training-Formal Research Training, Activities Driven by Doctoral Candidates, Career Development as well as Concepts and Structures. RESULTS: In all, 21 fellows from six African countries participated and all had been in the CARTA program for at least three years. The fellowship has increased fellows research skills and expanded our research capacities. This tremendously improved the quality of our doctoral research and it was also evident in our research outputs, including the number of peer-reviewed publications. The CARTA experience inculcated a multidisciplinary approach to our research and enabled significant improvement in our organizational, teaching, and leadership skills. All these were achieved through the well-organized structures of CARTA and these have transformed us to change agents who are already taking on research and administrative responsibilities in our various home institutions. Unfortunately, during the long break between the second and the third JAS, there was a gap in communication between CARTA and her fellows, which resulted in some transient loss of focus by a few fellows. CONCLUSION: The CARTA model which builds the research capacity of doctoral fellows through robust support, including intermittent strategic Joint Advanced Seminars has had effective and transformative impacts on our doctoral odyssey. However, there is a need to maintain the momentum through continuous communication between CARTA and the fellows all through this journey.

The burden of oral conditions among adolescents living with HIV at a clinic in Johannesburg, South Africa.

BACKGROUND: There are inconsistent reports on the prevalence of oral conditions and their associated factors among adolescents living with HIV (ALHIV). The current inconsistencies may hinder the development of clear guidelines on the prevention and treatment of oral conditions among ALHIV. This study provides an update on oral conditions and their associated factors in a cohort of South African ALHIV and receiving routine HIV treatment services at a Johannesburg HIV wellness clinic. METHODS: Decayed Teeth (DT), Decayed Missing and Filled Teeth (DMFT) and Oral HIV/AIDS Research Alliance case definitions were used for caries examination and reporting of the Oral Mucosal Lesions (OML) respectively. Data analyses were stratified by the study main outcomes; chi-squared tests were performed to determine the associations; and multiple logistic regressions were also used to identify associated factors after adjusting for other exposure variables. In addition to fitting logistic regressions, we explored the data for potential confounders and effect modifiers. RESULTS: A total of 407 ALHIV were assessed, of which 51.0% were females. The mean age of the ALHIV was 14.75 years (SD 2.43) while the median age of their parents was 43 years (IQR 37-48 years). Regardless of sex, age group and other socio-demographic characteristics, participants had high count of dental caries (DMFT>0). The overall prevalence of dental caries was 56.76% (n = 231) with mean DT score of 2.0 (SD 2.48) and mean DMFT score of 2.65 (SD 3.01). Dental caries prevalence (DT>0) was significantly associated with the HIV clinical markers. HIV RNA viral loads more than 1000 copies/ml and CD4 cell counts less than 200 count cells/mm3, increased the likelihood of having dental decay among ALHIV (p<0.05). ALHIV at WHO staging III, IV had higher caries prevalence ranging from 70% to 75% (p<0.05). The prevalence of dental caries was directly related to the presence of oral mucosal lesions (p<0.05). The prevalence of OML was 22%, with linear gingival erythema (13.8%) accounting for most of the OML. Multiple logistic regression modelling suggested that dental caries experience (DMFT>0), age category 13-15 years, WHO staging of IV and viral load of more than 1000 copies/ml significantly predicted the outcome of oral lesions as assessed using the OHARA case definitions (p<0.05). The odds of developing dental caries was also 1.5 times more among ALHIV who brush their teeth less frequently and those who reported more frequent eating of sugar sweetened diets (p<0.05). CONCLUSIONS: There is high prevalence of dental caries and OML among ALHIV in Johannesburg. The reported prevalence was associated with high HIV RNA viral loads, shorter duration on antiretroviral treatment and high WHO staging of HIV disease on crude analysis. Additionally, caries experience contributed to the prevalence of OML. Our study acknowledges the protective effect of HIV treatment and positive oral health practices on the presence of oral conditions among ALHIV in Johannesburg.

Systematic review of factors influencing oral health-related quality of life in children in Africa.

BACKGROUND: Oral health-related quality of life (OHRQoL) is influenced by cultural and societal context. Existing OHRQoL children measurement tools have been conceptualised in high-income countries. Probing whether the factors influencing OHRQoL are context-reliant in the African setting is necessary and is the purpose of the current review. AIM: To investigate if the factors influencing OHRQoL are context-reliant. METHODS: Seven databases were searched using search terms ('oral health'; and 'quality of life', 'health-related quality of life', 'patient-reported outcomes', 'well-being'; and 'child*', 'adolescents', 'teen*', 'youth'; and 'determinants', 'factors', 'predictors'; and 'oral health quality of life tools/instruments/scales'; and 'Africa*'). Abstracts identified were exported to a reference software manager. Three of the authors used specific selection criteria to review, firstly, 307 abstracts and, secondly, 30 full papers. Data were extracted from these papers using a pre-designed data extraction form, after which quantitative synthesis of data was performed. RESULTS: Key factors influencing OHRQoL followed an existing conceptual framework where environmental and individual factors in the form of socio-economic status (SES), area of residence and children psyche status, and the presence of any oral condition other than dental caries were reported among child populations in Africa. CONCLUSION: There is preliminary evidence to suggest an association between individual factors such as children's psyche and oral problems, excluding dental caries, and environmental determinants such as area of residence and SES in children's OHRQoL in African children. The finding that dental caries was not a key factor in child-oral health is unexpected. There seemed to be a contextual viewpoint underpinning the current OHRQoL frameworks and OHRQoL was context-reliant.
