title: Evaluation of Solubility and Microleakage of Glass Carbomer Sealant.
abstract: OBJECTIVE
  This study was carried out to evaluate and compare solubility and microleakage of the newly introduced moisture tolerant glass carbomer sealant.
  
  
  METHODS
  For evaluation of solubility, 20 specimens of glass carbomer and conventional glass ionomer were prepared and immersed in artificial saliva of pH 4 and 6 for seven days. The difference between initial and final weight was calculated. For evaluation of microleakage, glass carbomer was compared with a conventional resin sealant. 20 premolar teeth indicated for orthodontic extraction were collected and divided into two groups and the respective sealants were applied. It was subjected to thermocycling and then kept immersed in methylene blue for 24 hours. Dye penetration was scored.
  
  
  RESULTS
  The glass carbomer specimens were less soluble than the conventional glass ionomer at both pH values. There was no significant difference in the microleakage.
  
  
  CONCLUSIONS
  Being moisture resistant, glass carbomer can be used as an alternative fissure sealant material; especially in young children with partially erupted teeth and where obtaining moisture control is difficult.
