  • Resin-based sealants are basedon acrylic (methacrylate), may or may not contain filler particles or fluoride, and the setting reactioncan be automatic (auto-polymerised) or light activated (light-polymerised). Low-viscosity resin-basedrestorative materials (flowable composites) have also been used as fissure sealants.Glassionomer sealants have evolved from glass ionomer cements, which can adhere directly to toothsubstance.15 Glass ionomer materials release fluoride over time and have the advantage of being lesssensitive to moisture contamination than resin-based materials, making them a potential alternative toresin-based sealants when moisture control is an issue

  • the impact of fissure sealants alone onreducing caries is likely to be less for primary teeth than for permanent teeth.
  • careful visual assessment of the tooth was appropriate for assessingthe need for sealants, and also that existing radiographs, if recent, should be consulted before sealantapplication. Additional caries detection tools should only be considered when there is concern thatcaries might extend into dentine.
