Purpose: The aim of this study is to compare the pain perception of two different frequencies of archwire activation.

Methodology: 19 patients were divided into 2 groups. In the intervention group the archwire was changed every 6 weeks while in the control group the archwire was changed every 4 weeks. Discomfort score data sheets were delivered to the patients after the orthodontic visit. The patient recorded the discomfort score after 4 hours, 24 hours, 3 days and 7 days.1 score means minimum discomfort while a 7 score means maximum discomfort.

Results: The difference in the discomfort score between both groups was statistically insignificant.

Conclusion: The discomfort scores between both activation frequency rates showed no significant difference and the pain decreased gradually throughout time in both groups.

Trial number registration: ClinicalTrials.gov with an identifier number.
