Summary

White spot lesions (WSLs) are a common esthetic complication during orthodontic treatment. While clear aligners (CAs) generally reduce WSL risk compared to fixed appliances, composite attachments remain plaque-retentive sites. This two-arm clinical trial investigated the effect of shifting attachments to lingual surfaces on WSL development.
