title: Comparative Evaluation of Shear Bond Strength of Various Glass Ionomer Cements to Dentin of Primary Teeth: Anin vitroStudy.
abstract: OBJECTIVE
  To evaluate and compare shear bond strength of various glass ionomer cements (GICs) to dentin of primary teeth.
  
  
  METHODS
  Sample size taken for the study was 72 deciduous molars with intact buccal or lingual surfaces. Samples were randomly divided into three groups, i.e., groups A, B, and C and were restored with conventional type II GIC, type II light cure (LC) GIC, and type IX GIC respectively. Thermocycling was done to simulate oral conditions. After 24 hours, shear bond strength was determined using Instron Universal testing Machine at crosshead speed of 0.5 mm/ minute until fracture. Results were tabulated and statistically analyzed.
  
  
  RESULTS
  It was found that the shear bond strength was highest in group B (LC GIC) 9.851 ± 1.620 MPa, followed by group C (type IX GIC) 7.226 ± 0.877 MPa, and was lowest in group A (conventional GIC) 4.931 ± 0.9735 MPa.
  
  
  CONCLUSIONS
  Light cure GIC was significantly better than type IX GIC and conventional GIC in terms of shear bond strength.
