title: Effect of self-brushing with acidulated phosphate fluoride (pH 5.6) on dental caries in children.
abstract: The aim of this work was to study the effect of a preventive program on the dental plaque and on the caries incidence in school children. The program comprised weekly supervised self brushing with acidulated phosphate fluoride (APF) gel (pH 5.6; concentration: 4520 ppm of ion F-). The program involved 240 children of 1st., 3rd and 5th grade of a primary school in the City of Buenos Aires (Argentina). The population was divided in 2 groups: A (experimental) and B (control). Ninety children from both groups (45 experimental and 45 control) were submitted to baseline clinical examination (DMFT and plaque index) and microbiological analysis (total streptococci, St mutans and St. mutans and St. mutans percentage). Group A was then submitted to a preventive program which included self brushing with APF gel (4520 ppm of ion F-). The 90-children sample was monitored after 1 and 2 years of program. Results were statistically processed and they revealed the following: a--DMFT was significantly greater in the control group than in the experimental group after 1 and 2 years of program; b--an 81.43% reduction in caries increment rate at the end of the 2-years program in the experimental group as compared to the control group; c--a rise in the number of colonies of total streptococci and of St. Mutans; d--a reduction in the % of St. mutans in the total streptococci flora in the plaque of children in the experimental group; e--the presence of St. mutans colonies featuring a rough surface; f--the effectiveness of the program in the modifying the profile of the diagnosed dental pathology.
