J Oral Rehabil 2004; 31(10):979–84.
Material: Fluoride-containing Helioseal F fissure sealant, and conventional Concise Light Cure White Sealant fissure
sealant
Selection of Teeth and Tooth Type or Morphology: First and second permanent molars
Technique:
1. Use cotton wool rolls for isolation, along with a flexible plastic saliva ejector.
2. Clean the tooth with a prophylaxis brush using nonfluoridated pumice.
3. Rinse, then dry.
4. Etch, rinse with water for 20 seconds, then dry with air blast (until tooth has chalky, frosted appearance).
5. Apply fissure sealant materials according to manufacturer’s instructions.
6. Cure for 40 seconds with Coltolux 4 (Colténe, CH 9450, Switzerland) dental curing light.
7. No repair or replacement of insufficient sealants.

cements used as fissure sealants. Community Dent Oral Epidemiol 2003; 31(5):386–91.
Material: Vitremer resin-modified glass ionomer cement (3M ESPE, St Paul, Minn.) and Ketac-Bond conventional
glass ionomer cement (3M ESPE)
Selection of Teeth and Tooth Type or Morphology: Permanent first molars
Technique:
1. Pumice prophylaxis of the occlusal surfaces
2. Cotton roll isolation
3. 30 seconds conditioning with 35% phosphoric acid gel
4. Wash, cotton roll substitution
Vitremer application:
1. Primer application for 30 seconds
2. Air-drying and light-curing for 20 seconds
3. Mixing of material in a 1:2 powder–liquid ratio, to obtain lower viscosity so that the mixture flows into the fissures
4. Insertion of material into fissures with an explorer, along the entire extension
5. Light-curing for 40 seconds
6. Application of “Finishing Gloss” followed by light-curing for 20 seconds
7. Verification and adjustment of occlusal contacts when necessary
Ketac-Bond application:
1. Mixing of material in a 1:1 powder–liquid ratio, to obtain a luting consistency
2. Insertion of material into fissures with an explorer, along the entire extension
3. 5-minute wait for initial curing mechanism
4. Material covered with unfilled resin to maintain moisture balance
5. Checking and adjustment of occlusal contacts when necessary
