BMC Oral Health

Table 5 The comparison of p-values for 6 participants with 4 sample entropy features under two psychological states (healthy controls and bruxsim) for C4P4 channel

SN	Features	healthy controls (mean ± SD)	Bruxsim (mean ± SD)	p-value
1	SampEn(δ)	0.530 ± 0.002	0.572 ± 0.006	<=0.001**
2	SampEn(θ)	0.822 ± 0.001	0.810 ± 0.005	0.695
3	SampEn(α)	0.977 ± 0.003	0.957 ± 0.007	0.01*
4	SampEn(β)	1.378 ± 0.006	1.303 ± 0.013	<=0.001**

The ‘*’ and ‘**’ represent alpha levels: p = 0.05, and p = 0.001 correspond to significant differences, respectively
