Context and objective As elsewhere, disadvantaged children in Senegal are those most affected by dental diseases and difficulties in obtaining dental care. Studies conducted mainly in developed countries suggest that a low level of mothers' OHL is correlated with poor oral health of their children. The objective of this study is to estimate the level of mothers' OHL in Senegal and its relationto the dental health of their children. Methods This cross-sectional epidemiological survey took place among 315 children aged from 3 to 9 years old and their mothers. It estimated the children's dental health status by clinical examination which used a disposable examination kit and a headlamp, took place at the child's home, in the mother's presence. Examiners interviewing the mothers administered the Oral Health Literacy-Adult Questionnaire to determine their OHL and questioned them further about their social characteristics and their children's dental health behaviour. Logistic regression and correlations were used for the statistical analysis. Results The OHL score ranges from 0 to 17; mothers' mean score was 6.5 (±3.1) and 56.5% had a low score (below the median). The prevalence of dental caries in children was 64.8%. Mothers' high OHL is associated with children caries free and low prevalence of dental caries. The logistic regression showed a significantly protective relation between children's dental caries and mothers' high OHL scores (mean score 12-17) (OR = 0.51, 95% CI: 0.29-0.88), high educational level (OR = 0.42, 95% CI: 0.23-0.76) and a high level of social contact (OR = 0.31, 95% CI: 0.15-0.63). The structural analysis showed that OHL was significantly correlated with both the mothers' social position (r = 0.61 and P<0.001) and the children's caries (r =-0.26 and P<0.001).
Cette étude avait pour objectifs : 1) d’identifier et de caractériser les acteurs impliqués dans la filière des produits à usage médicinal tirés de Cordyla pinnata, Detarium microcarpum et Detarium senegalense au Sénégal; 2) d’analyser l’organisation de cette filière et l’importance des parties utilisées ; 3) d’analyser la commercialisation de ces produits ; 4) d’identifier les forces, faiblesses, opportunités et menaces de la filière. L’échantillonnage en boule de neige a été utilisé et a permis d’interroger, à l’aide de guides d’entretien 13 tradipraticiens locaux, 3 récolteurs et 17 herboristes. Les résultats ont révélé que les acteurs de cette filière, majoritairement des hommes, entretenaient des relations de coopération et qu’ils bénéficiaient de l’appui de la société civile en termes de formation et d’organisation. Les racines et les écorces de Cordyla pinnata et Detarium microcarpum étaient plus utilisées tandis que celles de Detarium senegalense étaient peu commercialisées. Les écorces, les racines et les feuilles étaient vendues entre 0,11 et 0,29Euro/100g. Une partie des écorces était transformée en poudre avant d’être commercialisée chez les herboristes entre 1,05 Euro/100g (pour Cordyla pinnata) et 1,52 Euro/100g (Detarium microcarpum). Les prix étaient plus élevés à Dakar. Les parties tirées de Cordyla pinnata étaient essentiellement utilisés contre les parasitoses intestinales tandis que celles de Detarium microcarpum et dans une moindre mesure celles de Detarium senegalense servaient à soigner les dermatoses. Les faiblesses de cette filière concernaient essentiellement l’exploitation anarchique de la ressource et la raréfaction saisonnière de certains produits tandis que l’éloignement des sites d’approvisionnement menaçait son bon fonctionnement.

(FCA) highlighted species-organ relationships. Frequency of citations, fidelity index, selling price were used to show the socioeconomic importance of the species. Results identified 62 edible species belonging to 31 families and 54 genera. These species were dominated by Annonaceae, Apocynaceae and generic diversity was more pronounced among Anacardiaceae. Identified species were mainly used for food (53%), energy (16%), technology (12%) and medicinal purposes (12%). The FCA showed three organ-use groups with a strong correlation between fruit and root on the one hand and leaf, bark and wood on the other. The study also identified 16 commercialized species. The fruit was the main organ consumed and marketed. The highest number of organs commercialized were recorded for Elaeis guineensis (4 organs) and Borassus aethiopium (3). These products, often collected and sold by women and children, came from villages and transited to markets through the "bana bana". Their prices depended on the locality isolation and the production period. These results open up perspectives for better management of the supply and commercialization of these forest resources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
