Table 5 Summary of the parameters and results collected for the studies included in the qualitative analysis

Pasqualini et al., 2012 [18]

5-level pain scale form

24, 48, 72 h

No pain (0), slight pain (1), mild pain (2), severe pain (3), very severe pain (4), extremely severe pain (5)

24 h: ^IIM-GP (1.38) > ^ICR-GP (0.94)

^IIM-GP (3.7 ± 2.2) > ^ICR-GP (2 ± 1.7)

48 h: ^IIM-GP (1.19) > ^ICR-GP (0.71)

72 h: ^IIM-GP (0.95) > ^ICR-GP (0.48)

3-level pain scale form

#

Completely painless (1); mild pain, does not affect occlusion and eating (2); severe pain, affecting occlusion and eating (3)

^IIIWGP (1.33 ± 0.55) > ^I,IICR-GP (1.14 ± 0.36)

#

Guo et al., 2014 [33]

Visual analogue scale

#

10 cm ruler marked 0 to 10 scale: pain (value 3-10) or no pain (value <3)

^I,IICR-GP (15-20%) = ^III,IVM-GP (25-35%)

Adıgüzel et al., 2019 [2]

Visual analogue scale

24, 48, 72 h

No pain (0), mild pain (1–3), moderate pain (4–6), severe pain (7–10)

24 h: ^IIR-GP (2.00 ± 1.87) = ^IIIWGP (3.71 ± 2.03) > ^ICR-GP (1.05 ± 1.07) = ^IIR-GP
