Tooth surfaces with pits and fissures have always

• Tooth surfaces with pits and fissures have always been the earliest and most prevalent of carious area

What is sealant • Material that is introduced into the occlusal pits and fissures of cariessusceptible teeth, thus forming a micromechanically-bonded, protective layer cutting access of cariesproducing bacteria from their source of nutrients Simonsen R. J. et al. , 1978

How to success • Sealants are an important dental caries prevention technology

Etching

��� etch ����� ? 15 ��� • Clean dry (and free of saliva and water contamination) enamel surface was essential for a strong bond of the sealant to enamel • The etching times for primary enamel can also be decreased over the times originally proposed. A short etch time of 15 seconds was found to be satisfactory for primary enamel (Tandon S. et al. , 1989) • It was concluded that the different etching times do not appear to affect the retention of fissure sealants on the first permanent molars or second primary molars (Duggal M. S. et al. , 1997)

Clinical review • 70% caries reduction over 1 year at 2 years, 98% caries reduction (Thylstrup and Poulsen. , 1978) • The longest studies reported for 10 year longer (Richard. , 2002) • The effective treatment has lower failure
