title: Microleakage of composite-ionomer laminate restorations: an in vitro evaluation.
abstract: The in-vitro study undertaken on sixty teeth, 30 each of second primary molars and first premolars to evaluate the effectiveness of sealing property of composite-ionomer laminate restorations given on buccal aspects of these teeth after either Dycal base, ionomer base not etched and ionomer base etched indicated significantly more microleakage in dycal base composite resin restorations than composite ionomer. No difference in microleakage was seen in etched and unetched composite ionomer laminate restorations. Though microleakage was observed more in primary teeth than permanent teeth it was not found to be statistically significant.
