DE ARAUJO SILVA, Thiago Fernando et al. Experimental model of tooth decay as an educational tool for school-age children. Rev. salud pública [online]. 2016, vol.18, n.2, pp.1-290. ISSN 0124-0064.  https://doi.org/10.15446/rsap.v18n2.34321.

Objective This work consisted of the construction of an educational in vitro model of dental caries that started with an adaptation of Miller's classic experiment. Methods In a sterilized and sealed glass jar, a sample paste of human saliva was collected and a substrate of manufactured sugar (sucrose) was added. In addition, a human tooth with healthy dental crown extracted in dental treatment but otherwise healthy was added. Research phase I had the negative control sample test (tooth + saliva without added) and the others were opened after 1, 2, 3 and 4 months of incubation. This phase was essential for the next experimental time development. In phase II, two saliva donors with poor levels of oral health habits were recruited. The incubation time (defined by phase I) was 2 and 3 months for each donor. Results This research data gives the possibility of building educational materials about the etiology of tooth decay and its clinical evolution. It also makes possible the production of an explanatory sheet about how to reproduce this experimental model to be used by school children in secondary education. Conclusions Doing this kind of work together at school can help reduce inequities in oral health, especially since there is an approximation toward the discourses, facilitating the process of information dissemination.
