Dentin Pretreatment using Doxycycline Hydrochloride for Improving Push Out Bond Strength

Aim: The aim of this study was to assess and compare the effect of Doxycycline hydrochloride pretreatment of root dentin on pushout bond strength (POBS) of fiber post luted using self-adhesive resin cement. The effect of DXC at 0.2% on the mean Push out Bond Strength of the adhesive-dentin interface was evaluated. Data was analysed by applying independent student ?t? test with a level of significance set at P<0.001. Dentin pretreatment with Doxycycline hydrochloride has shown a statistically significant increase in the push out bond strength.
