Evaluation of the Fracture Resistance of Conservative and Ultraconservative Access Cavity Designs with Different Treatment Modalities: An In Vitro Study

Table 1

Descriptive features of fracture force (Newton) and fracture model in different groups.

No.	Group	Number	Mean fracture	Fracture mode
				Restorable	Nonrestorable
1	Group A3	10	[3, 5–10]	2	8
2	Group C1	10	[3, 5–10]	8	2
3	Group C2	10	[1, 2, 4, 8–10]	0	10
4	Group A2	10	[3, 5, 7–10]	1	9
5	Group A1	10	[1, 2, 4, 8–10]	0	10
6	Group B3	10	[1, 2, 7–10]	8	2
7	Group C3	10	[1, 2, 4, 6, 9, 10]	8	2
8	Group B2	10	[1–6, 9, 10]	8	2
9	Group B1	10	[1–8, 10]	9	1
10	Control	10	[1–9]	10	0

Different figures above the mean of each group show the number of groups that have a significant difference with the respective group in the amount of fracture force.
