Comparative Evaluation of Different Numerical Pain Scales Used for Pain Estimation during Debonding of Orthodontic Brackets

Table 2

Descriptive statistics for PCS scores.

PCS score	Finger pressure	Stress relief	Elastomeric wafer	Chi square	value
Rumination	5^a	5^a	8^b	18.20	≤0.001 (s)
Magnification	4^a	3^b	4^a	10.40	0.02 (s)
Helplessness	4^b	5^a	6^a	6.63	0.04 (s)
Total	14	12	18	19.39	≤0.001 (s)

and statistically significant. Post hoc test was conducted to pinpoint a difference within the groups. Different alphabets express that there is a statistically significant difference: EW has a high score in the rumination group compared to FP and SR. SR has the lowest score compared to FP and EW in terms of magnification. FP has the lowest score compared to SR and EW in terms of helplessness.
