Clinical Performance of Light-cured Orthodontic Adhesives for Bonding Brackets – An In-vitro Study.

This was an in-vitro study conducted on 80 extracted maxillary premolars. Teeth with the sound crown structure were acid etched and bonded with brackets on their buccal surfaces utilizing primer and light-cured adhesives into four equal groups, which are Transbond XT, Heliosit, Enlight, and Bracepaste. Shear Bond Strength (SBS) for de-bonding the brackets were evaluated with Instron- testing machine after 48 hours. The de-bonded samples’ Adhesive Remnant Index (ARI) scores were also measured.
