title: Comparison of the remineralisation effect of a glass ionomer cement versus a resin composite on dentin of primary teeth.
abstract: OBJECTIVE
  The aim of this study was to investigate the interaction of a high viscosity glass ionomer cement (GIC) and a composite resin with caries affected dentin and to determine the remineralization levels.
  
  
  METHODS
  In a split mouth design 24 GIC and composite resin atraumatic restorative treatment restorations were made in vivo and the teeth were collected after 2 years and subsequently sectioned and examined using Vickers microhardness test; the latter was performed starting from the dentin surface adjacent to the restoration. Repeated Measure ANOVA and Bonferroni statistical methods were used for data analysis.
  
  
  RESULTS
  The microhardness adjacent to the GIC restorative material resulted to be significantly higher.
  
  
  CONCLUSIONS
  GIC resulted to be a better restorative material for the remineralization of caries affected dentin, though further studies are necessary for the corroboration of this finding. The GIC restored primary molar dentin had a higher level of remineralization and GIC could be the material of choice in pediatric dentistry.
