Lecture title: Effect of Different Er:YAG Etching Settings on Shear Bond Strength of Orthodontic Ceramic Brackets

Lecture abstract: Since the last few decades, there is growing interest in ceramic brackets especially in adults. Conventional etching produces demineralization of the superficial layer, and leads to high level of bond strength that can be related to both considerable patient discomfort and a high risk of enamel damage while debonding. With the introduction of Erbium lasers into the orthodontic field, Er:YAG laser showed an important advantage related to the ability to adjust its settings while etching. This would help reaching an adequate ceramic brackets shear bond strength while respecting the enamel integrity. Could Er:YAG laser be a viable alternative to phosphoric acid?
