Abstract:
This study compared the marginal leakage of nano-particle-filled resin-modified glass ionomer (RMGIC) restorations made using atraumatic restorative technique (ART) and conventional technique. Twenty primary molars with carious dentin on the buccal surfaces were restored with RMGIC using ART. The teeth were thermally cycled, sectioned and stained with methylene blue. Micro-leakage was compared to a second set of teeth restored conventionally. No significant difference (p > 0.05) in leakage was noted between the conventional and ART groups. The authors concluded that ART with RMGIC provides margins that show comparable leakage to conventionally restored primary teeth.
