Aim:
To compare the pain ratings of patients treated with labial and lingual fixed orthodontic appliances over 3 months.
Material And Methods:
Thirty patients aged 15-35 years were divided into two groups (Group A: labial, Group B: lingual). Pain perception was assessed using the Visual Analogue Scale (VAS) and Pain Measurement Scale (PM) at 1 week, 1 month, and 3 months.
Results:
Lingual appliance patients reported more pain in the first week, which decreased significantly by the third month. Labial appliance patients experienced increasing discomfort over time.
Conclusion:
Pain perception differs between labial and lingual treatments, with lingual appliances causing initial discomfort that lessens over time and labial appliances showing the opposite trend.
