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.

An in vitro study conducted on 30 primary second deciduous molars and 30 second premolars to evaluate the tensile bond strength of composite ionomer restorations revealed that (i) glass ionomer cement base was superior than Dycal under composite restorations; (ii) etched glass ionomer base provided optimal bond strength in both primary and permanent teeth; (iii) tensile bond strength was high in permanent than in the primary teeth; and (iv) composite ionomer laminate can be considered as a material of choice for restoration of primary teeth.
