Table 2 Comparative analysis of microleakage with negative control and positive control

Groups	Mean (OD) ± S.D	Negative Control Mean (OD) ± S.D	P-value	Positive Control Mean (OD) ± S.D	P-value
Group IIA	0.550 ± 0.060		0.0001		0.0001
Group IIB	0.557 ± 0.095		0.0001		0.0001
Group IIIA	0.278 ± 0.042		0.084		0.0001
Group IIIB	0.254 ± 0.055	0.130 ± 0.029	0.234	0.948 ± 0.287	0.0001

Illustrates the comparison of mean ± S.D. of OD for samples filled with GIC, MTA and Biodentine in which retrograde cavity was prepared by two different round burs: Carbide versus Diamond with that of negative and positive control group. The significant difference was observed between GIC and negative control (p = 0.0001) and GIC and positive control (p = 0.0001). The non-significant difference was observed between MTA and negative control (p = 0.084/Carbide, p = 0.234/Diamond) and the significant difference between MTA and positive control (p = 0.0001). Moreover, the non-significant difference was observed between Biodentine and negative control with both burs (p = 1.000) and significant difference observed between Biodentine and positive control (p = 0.0001) respectively.
