Introduction: The aim of this study was to compare the efficacy of ibuprofen, viscoelastic bite wafers, and chewing gum in reducing orthodontic pain.

Results: There were significant differences in pain perception of chewing function between the placebo group and the chewing-gum group at 24 hours and 7 days, and between the placebo group and the hard-viscoelastic group on the day 7 (P \0.05). Also, there were significant differences between the placebo group and the soft-viscoelastic group, and between the placebo group and the hard-viscoelastic group in pain severity when fitting posterior teeth at 6 hours (P \0.05). At other times and with other functions, no significant differences were recorded.

Conclusions: Both chewing gum and viscoelastic bite wafers are effective for pain reduction in orthodontic patients and can be recommended as suitable substitutes for ibuprofen.
