Summary
This review found no significant difference in white spot lesion formation between self-ligating and conventional orthodontic brackets. Oral hygiene remains the most critical factor in preventing these lesions.
Area of Science:
- Orthodontics
- Dental Materials Science
Background:
- White spot lesions (WSLs) are a common complication of fixed orthodontic treatment.
- Lesion formation often occurs around orthodontic brackets, impacting treatment outcomes.
Purpose of the Study:
- To systematically review and compare WSL formation between self-ligating brackets (SLBs) and conventional ligating brackets (CLBs).
Main Methods:
- A comprehensive literature search was conducted across eleven databases until January 2025.
- Included studies comprised randomized controlled trials, controlled clinical trials, and cross-sectional studies comparing WSLs between SLBs and CLBs.
- Risk of bias assessment was performed on included studies.
Main Results:
- Five studies (3 RCTs, 1 CCT, 1 cross-sectional) were included in the systematic review.
- Four out of five studies reported no statistically significant difference in WSL formation between SLBs and CLBs (p < 0.05).
- Three studies were assessed as having a low risk of bias.
Conclusions:
- Current evidence suggests no significant difference in WSL formation between self-ligating and conventional bracket systems.
- Orthodontists should prioritize patient education on oral hygiene, as it is the most critical factor in WSL prevention.
- Further research may be warranted to explore other contributing factors to WSL development.
