The term pit and fissure sealant (FS) describes a material introduced into occlusal pits and fissures of caries susceptible
teeth, forming a micromechanically-bonded, protective layer denying access of a caries-producing bacteria from their source of nutrients [Simonsen, 2002].
With proper placement and maintenance, a sealant has proven longevity and will protect the caries susceptible
pits and fissures of the tooth from decay.
However, none of the socio-demographic or behavioural variables, including the confirmed risk indicators, had enough predictive power to be considered as risk predictors for identifying caries susceptible
children (the model with the highest predictive power reached a sensitivity+specificity level of 131).
