Aims: To study the fluoride release and retention of new-shaped glass slow-release F devices (SRFD) in vivo in children. Methods: A group of 15 children had one slow-release F glass device with 17.4% or 14.8 mgm F with a relative solubility of 294, attached intraorally on the buccal surface of one of their maxillary permanent molars. The devices were monitored for 6 months. Results: The retention rate of the devices was 93% and the mean salivary F levels in the child volunteers was 0.17±0.1 ppm F compared with 0.025 ppm F baseline levels. The difference was always statistically significant] (p<0.01). There were no systemic or local side-effects. Conclusions: The devices were well tolerated by children and released fluoride intraorally for the whole period of six months to a level consistent with inhibition of demineralisation.
