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

Table 1

Mean ± SD of fracture resistance (N) in the experimental groups and fracture pattern (restorable/nonrestorable).

Type of restoration	Size of restoration		value
	Conservative	Extended
Cention	882.70 ± 163.44^b, A (5/5)	804.90 ± 165.90^a, A (4/6)	0.300
Bonded Cention	1210.50 ± 230.97^a, A (7/3)	760.50 ± 85.66^a, B (7/3)	≤0.001
Composite	1052.30 ± 147.60^ab, A (5/5)	816.30 ± 108.95^a, B (2/8)	≤0.001
value	≤0.001	0.580	—

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).
