Fracture Strength and Marginal Adaptation of Conservative and Extended MOD Cavities Restored with Cention N

Table 2

Mean ± SD of marginal adaptation (%) of experimental groups.

Type of restoration	Size of restoration		value
	Conservative	Extended
Cention	93.01 ± 4.54^a, A	95.15 ± 5.40^a, A	0.440
Bonded Cention	96.38 ± 4.60^a, A	90.95 ± 7.28^a, A	0.120
Composite	92.52 ± 4.06^a, A	81.45 ± 7.54^b, B	≤0.001
value	0.230	≤0.001	—

Different lower case letters show significant difference in each preparation size (in a column). Different upper case letters show significant difference in each type of restoration (in a row).
