Table 2. Comparison of marginal adaptation among different types of restoration according to time and site.

		Restoration
		GIC	RMGI	BIR
Abbreviations: BIR, bioactive ionic resin; GIC, glass ionomer cement; RMGI, resin-modified glass ionomer. Note: Data are expressed as median (IQR), IQR: interquartile range. Significance < 0.05. Different letters represent significant differences. Capital letters represent significance between restoration groups for immediate and delayed; enamel and dentin. Small letters represent significance between immediate and delayed within enamel and dentin for each restoration.
