Pain experience during initial alignment with self-ligating and conventional fixed orthodontic appliance system: A...

Area of Science:

• Orthodontics
• Pain Management
• Biomaterials

Background:

• Orthodontic treatment involves bracket placement, which can cause patient discomfort.
• Self-ligating brackets are marketed as potentially reducing pain compared to conventional brackets.

Purpose of the Study:

• To compare the pain experienced by patients using self-ligating (SmartClip™) versus conventional (Victory™) preadjusted edgewise brackets during the initial alignment phase of orthodontic treatment.

Main Methods:

• A randomized controlled trial involving 73 patients (15-21 years) allocated to either SmartClip™ or Victory™ appliances.
• Pain was assessed using a 100-mm visual analogue scale (VAS) at five time points post-bracket placement.
• Independent t-tests were used to compare pain scores between the two groups.

Main Results:

• Pain intensity peaked between 24 hours and 3 days after bracket placement and subsequently decreased.
• No statistically significant differences in pain scores were found between the self-ligating and conventional bracket groups at any assessed time point (P > 0.05).

Conclusions:

• The study found no clinically significant differences in perceived pain between self-ligating and conventional orthodontic bracket systems during initial alignment.
• Current evidence does not support the claim that one bracket system provides superior pain relief over the other.
