nan nan The purpose of this study was to evaluate the separate effect of fluoride dentifrice, fluoride mouthrinsing and fluoride varnish on approximal dental caries. All 252 13-14-yr-old children at an elementary school were selected at random and divided among four groups for a 3-yr longitudinal study. Group 1 received a fluoride dentifrice for home care and a fluoride mouthrinse once a week. Group 2 received a fluoride dentifrice for home care and a placebo mouthrinse once a week. Group 3 received a fluoride dentifrice for home care and a fluoride varnish once every 3 months. Group 4 received a placebo dentifrice for home care and a fluoride rinse once a week. Fluoride rinsing did not give any additional effect compared with placebo-rinsing when a fluoride dentifrice was used for home care. Fluoride varnish gave a significant caries reduction compared with fluoride rinsing. nan The study's purpose was to evaluate the reduction of dental caries incidence by the association of two preventive methods. 246 students of both sexes aged from 7 to 11 years registered in "Escola de Educação Básica da Universidade Federal de Uberlândia" and living in the urbana area of Uberlândia, state of Minas Gerais, were examined. The sample was distributed into two groups: children from Group 1, which received a semestral topical application of Acidulated Fluor Phosphate at 1.23% and children from Group II, that besides the topical application above related (Group I) also received weekly mouthwashes of sodium fluoride aquesus solution at 0.2%. After two years of study DMFS index were tabled and statistically analysed. It was verified a reduction of 33.97% in the incidence of dental caries (in the permanent dentition). The difference between the Groups was significant at 5% level of confidence. 751 14- and 15-year old children completed a 3-year, double-blind, caries preventive program. The effects of daily, supervised toothbrushing with an 0.76% sodium monofluorophosphate dentifrice, rinsing with a 0.05% sodium fluoride mouthrinse, and the combined effects of the two treatments were investigated. Both the dentifrice and mouthrinse reduced the incidence of dental caries, but their combined use at the same time had no greater effect than either used alone. 376 three-year old children were divided into four experimental groups and exposed to different combinations of preventive programs for a period of two years. All the groups were given the same basic prophylactic information. Additionally Group I received fluoride tablets (FLUDENT) for daily sucking twice a day plus a placebo dentifrice free of fluoride. Group II was given a fluoride dentifrice containing 0.025% F, (ACTA). Group III was given a placebo dentifrice plus fluoride varnish (Duraphat) twice a year. Group IV a fluoride dentifrice containing 0.025% F (ACTA) plus fluoride varnish (Duraphat) twice a year. No statistically significant difference in caries increment during the two experimental years was found between the groups. A tendency to lower caries increment was found in Group IV, i.e. in the children using the low fluoride dentifrice and treated twice a year with fluoride varnish. nan The study groups using a dentifrice and mouthrinse both containing fluorides, a dentifrice containing stannous fluoride and a mouthrinse containing sodium fluoride, or a mouthrinse containing sodium fluoride with a placebo dentifrice had a 20.7% to 29.0% lower DMF increment than the control group after 30 months. These differences were significant. The study groups using a dentifrice containing amine fluorides and a placebo mouthrinse, a mouthrinse containing amine fluorides and a placebo dentifrice, or a dentifrice containing stannous fluoride and a placebo mouthrinse had a 13.6% to 22.4% lower DMF increment than the control group. These differences were not statistically significant. There was no significant difference in effectiveness against caries between the use of the organic or inorganic fluoride products.
