Self-assessment of dental health status, behaviours and oral health risk factors among adolescents from public schools in Maputo City-Mozambique.

Self-assessment of dental health status may have an impact on the oral health behaviour of adolescents which could impact their oral health. Oral health has been linked to various medical health conditions, thus eliminating oral health diseases can improve general health. The present study aimed to assess the association between behaviours and risk factors (oral hygiene habits, sugar intake, urban/rural status) and negative self-perception of dental health status among adolescents attending public schools in Maputo City.Method An analytic cross-sectional study, conducted in three Primary public schools from urban and peri-urban areas in Maputo City selected by convenience due to their geographic location was included. The size of the sample was 236 12-year-olds. Data was collected using a self-completion questionnaire designed by the World Health Organization (WHO). Chi-square tests or Fishers' Exact tests were used for associations. A simple and multiple logistic regression was used to determine the strength of these associations using backward elimination (p < 0.05). Results: The sample consisted of 221 adolescents, with 114 (51.6%) residing in urban areas and 107 (48.4%) in peri-urban areas. More than half of the participants (111 individuals) reported having a negative perception of their dental health. In the urban location, a higher percentage of participants had a "negative" perception of dental health (57.9%, n = 66), while in the peri-urban location, more participants perceived their dental health as "positive" (57.9%, n = 62). Participants residing in an urban setting were 82% more likely to have a negative perception of dental health (AOR = 1.82 [95% C.I.: 1.05 to 3.14]). Those who had experienced dental pain tended to report a higher proportion of negative dental perception (57.2%, n = 91), with 2.7 times more likely to report a negative perception of dental health (AOR = 2.72 [95% C.I.: 1.46 to 5.08]). The majority (n = 139; 63.2%) claimed to clean their teeth twice a day.Conclusion There was a higher negative perception of dental health in urban areas. The need to strengthen oral health promotion in urban schools is high since schools play such a significant role in oral health promotion.

Maternal and infant risk factors and risk indicators associated with early childhood caries in South Africa: a systematic review.

OBJECTIVES: To evaluate the risk factors and risk indicators associated with early childhood caries in South Africa. DESIGN: A systematic review of aetiology was performed. From 1366 papers found, 23 studies met the eligibility criteria and were included. All study designs were included. Healthy children under six who live in South Africa were eligible for the study. The study was registered with PROSPERO, registration number CRD42020216455. DATA EXTRACTION: Eligible studies were selected, and data extracted independently by two reviewers. Published data on socio-economic status, dietary factors, oral hygiene knowledge and practices, breastfeeding and bottle-feeding practices, oral bacterial flora and other risk indicators were collected. Two authors appraised the studies independently using the Joanna Briggs Critical Appraisal tools. DATA ANALYSIS: Heterogeneity was assessed using the I2 statistics, and due to heterogeneity, extracted data were mostly presented narratively. RESULTS: Meta-analysis was performed using random-effects models and concluded that parents of children who had a tertiary education had a 1.77 [1.22-2.57] odds of experiencing dental caries compared to the children of parents with a secondary education. However, the unclear risk of bias of most included cross-sectional studies precluded definitive conclusions. CONCLUSIONS: More high-quality cohort studies need to be performed to evaluate actual risk factors for ECC in a South African setting. Parental/caregiver oral educational knowledge needs promoting before the emergence of their children's teeth. The social determinants of health need to be incorporated in future studies, and suitable targeted interventions need to be developed and implemented to mitigate early childhood caries in South Africa.

Recruiting and retaining rural students: evidence from a faculty of dentistry in South Africa.

INTRODUCTION: There is a shortage internationally of adequately trained health professionals to service rural areas. Health professionals are more likely to practice in communities that are like the one in which they grew up. The WHO therefore suggests targeted university admission policies to facilitate the enrolment of students from rural areas. In South Africa, rural students have special needs with regard to university access and throughput because they come from the most economically disadvantaged communities and often are the first in their families to attend university. This descriptive study, the first in South Africa with a cohort of dentistry students, draws on data from undergraduates at a single faculty of dentistry in South Africa. It investigates the factors affecting rural students' access to university, their academic success, as well as their employment intentions. METHODS: A self-administered questionnaire was completed by 304 (70%) of the total number of 435 undergraduate dental students. Closed questions elicited information regarding students' year of study, academic performance, source and adequacy of funding, family history of university attendance, and area of origin. Responses were analyzed using MS Excel and Epi Info™. Qualitative data were used to support quantitative findings. Open-ended questionnaire questions, including employment intentions, and three focus group interviews generated examples to illustrate and elaborate the quantitative findings. RESULTS: Only 7% (n=22) of the cohort (n=304) were from rural areas. Rural students relied on assistance from those with university experience to apply and register, for course information and funding opportunities. Most rural students were funded by provincial bursaries (41%; n=9) and National Student Financial Scheme (NSFAS) funding (18%; n=4). Forty-four percent (n=4) of the rural students with provincial bursaries and 100% (n=4) of the rural students with NSFAS funding reported not having enough money for food. All NSFAS-funded rural students (n=4) reported not having enough money to buy the prescribed and recommended texts. Fifty percent (n=2) of the rural students with NSFAS funding had failed at least one academic year. Rural students were least likely to have family members who had attended university. Rural students were three times more likely than other students to want to work in rural areas. CONCLUSION: Only a minority of dentistry students came from rural areas, and rural schools did not adequately prepare these students academically for university. Rural students also lacked immediate access to people with insight into the academic and socio-cultural aspects of higher education, including the process of independent learning. Despite financial and academic challenges, rural students had a significantly stronger commitment to rural employment than students from cities and towns. It is recommended that rural students should receive academic, financial, and mentoring support both before and during their studies.
