According to a new study use of an Er:YAG laser at 100 mJ/30 Hz combined with 60 seconds of acid etching produces excellent adhesion for attachments on fluorotic enamel -restoring bond strength to levels comparable with healthy enamel while avoiding over-etching damage.
The researchers found that this approach avoids the risk of over-etching, which can damage enamel structure, while still achieving strong adhesion for orthodontic attachments. Dental fluorosis can alter the mineralization of enamel, making it more resistant to acid etching and reducing bond strength for orthodontic brackets or attachments.
