A Mobile Dental System in Southern Africa

Recent studies indicate a great need for dental treatment and preventive services in dentally underserved communities in southern Africa. Geographic inaccessibility, limited financial resources, and a maldistribution of dental personnel are the main barriers to oral health care. This project describes the evolution and utilization of a unique, purpose-built, mobile dental unit (MDU). From a compact 2 x 2.5 meter box trailer, an enclosed area of 8 x 9 meters is formed by deploying a cover system housed on top of the trailer. Once deployed, the unit becomes four fully equipped dental operatories and a combined waiting and educational area, with all-weather protection. Comprehensive care is provided by dental auxiliaries. The underlying philosophy of the service is based on the primary oral health care approach. To date, the MDU has visited a wide variety of rural and urban communities where several thousand patients have been examined and treated. Assessment of the MDU indicates that it is an effective and viable alternative oral health delivery system.     

Planning the oral health workforce: Time for innovation

The levels and types of oral health problems occurring in populations change over time, while advances in technology change the way oral health problems are addressed and the ways care is delivered. These rapid changes have major implications for the size and mix of the oral health workforce, yet the methods used to plan the oral health workforce have remained rigid and isolated from planning of oral healthcare services and healthcare expenditures. In this paper, we argue that the innovation culture that has driven major developments in content and delivery of oral health care must also be applied to planning the oral health workforce if we are to develop ‘fit for purpose’ healthcare systems that meet the needs of populations in the 21st century. An innovative framework for workforce planning is presented focussed on responding to changes in population needs, service developments for meeting those needs and optimal models of care delivery.     

The economic burden of childhood pneumococcal diseases in The Gambia

Background

Streptococcus pneumoniae is a common cause of child death. However, the economic burden of pneumococcal disease in low-income countries is poorly described. We aimed to estimate from a societal perspective, the costs incurred by health providers and families of children with pneumococcal diseases.

Methods

We recruited children less than 5 years of age with outpatient pneumonia, inpatient pneumonia, pneumococcal sepsis and bacterial meningitis at facilities in rural and urban Gambia. We collected provider costs, out of pocket costs and productivity loss for the families of children. For each disease diagnostic category, costs were collected before, during, and for 1 week after discharge from hospital or outpatient visit.

Results

A total of 340 children were enrolled; 100 outpatient pneumonia, 175 inpatient pneumonia 36 pneumococcal sepsis, and 29 bacterial meningitis cases. The mean provider costs per patient for treating outpatient pneumonia, inpatient pneumonia, pneumococcal sepsis and meningitis were US$8, US$64, US$87 and US$124 respectively and the mean out of pocket costs per patient were US$6, US$31, US$44 and US$34 respectively. The economic burden of outpatient pneumonia, inpatient pneumonia, pneumococcal sepsis and meningitis increased to US$15, US$109, US$144 and US$170 respectively when family members’ time loss from work was taken into account.

Conclusion

The economic burden of pneumococcal disease in The Gambia is substantial, costs to families was approximately one-third to a half of the provider costs, and accounted for up to 30 % of total societal costs. The introduction of pneumococcal conjugate vaccine has the potential to significantly reduce this economic burden in this society.

     

Dental caries in a South African adult population: findings from the Cape Town Vascular and Metabolic Health Study

Objectives: Caries is a ubiquitous non-communicable disease worldwide. There is a paucity of literature on adult caries in Africa, with the last epidemiological caries study in South Africa conducted in 1988/1989. This article reports on the decayed, missing and filled teeth (DMFT) scores in relation to demographic characteristics for a mixed-ancestry South African population. Methods: This cross-sectional epidemiological study was part of the ongoing Cape Town Bellville South Vascular and Metabolic Health Study. Each participant signed an informed consent form prior to enrolling in the study. During a clinical examination, DMFT score and components were recorded for each participant. Data analysis was performed with the statistical Package STATA 15. Results: A sample of 1,885 participants was included in the study. Sixty-eight percent of the population experienced high DMFT scores. Mean DMFT score increased with age from 5 (≤ 24-year-old group) to 32 (≥ 75-year-old group, P < 0.001). It was higher in women than in men (28.5 vs. 18, respectively, P < 0.001). The missing component contributed 83% to DMFT score, followed by decayed (14%) and filled (3%) scores. Males had a higher average number of teeth present than females (18 vs. 6.5, P < 0.001). Conclusions: Dental caries experience was very high, with high levels of tooth loss in this community. These findings highlight limited access to preventive oral healthcare and a high rate of tooth extraction. Females presented higher levels of oral disease than males, indicating the need for preventive oral healthcare programmes in Cape Town, South Africa.Key words: Decayed, missing and filled teeth, caries, oral diseases, oral health
