Effect of Exposure Times of Sodium Hypochlorite before Acid Etching on the Microshear Bond Strength to Fluorotic Enamel.

Purpose: To evaluate the effects of different treatment time of 5.25% Sodium hypochlorite (NaOCl) on the microshear bond strength (μSBS), attenuated total reflection Fourier transform infrared (ATR-FTIR) and etching pattern in mild and moderate fluorotic enamel.

Study Design: Forty-eight fluorotic molars were divided into two groups: mild and moderate fluorotic enamel which were classified by a Thylstrup and Fejerskov index (TFI).
