The retention rate of sealant was time related, over the period of 5 years the status was such that in upper first permanent molars complete or partial retention was 94% whereas very interestingly in lower first per- manent molars, it was 78%. Moreover, in males
retention was more than in females. This was an interesting finding, despite of the well known fact that females take care of their oral hygiene more, the loss of sealants was more in them. It can be hypothesized and provides provision for further work if puberty and hormonal changes in females have any role to play in it.
