387
children of non-fluoridated area. DMFS increment of all surfaces, pits fissures and smooth surfaces during 2 years was calculated and compared between fluoridated and non-fluoridated area.
@ES The obtained results were as follows:
@EN 1. Mean DMFS of all surfaces was reduced 31.3% by water fluoridation.
