Etchants such as acidulated phosphate fluoride (APF 1.23%) and hydrofluoric acid (HF) are often used for this purpose. APF gel is harmless for oral mucosa unlike HF, which can cause tissue irritation. Therefore, the present study aimed to evaluate the shear bond strength between composite resin and ceramic after various durations of surface treatment with APF gel.</font></span></p> <p align="left"><font face="Times New Roman" size="3">&nbsp;</font></p> <p align="left" style="margin: 0cm 0cm 10pt text-align: left line-height: 150% unicode-bidi: embed direction: ltr"><font face="Calibri"><b><span style="line-height: 150% font-size: 14pt mso-bidi-font-family: Calibri mso-bidi-language: AR-SA mso-fareast-font-family: Calibri mso-bidi-theme-font: minor-latin">Materials and Methods</span></b><span style="line-height: 150% font-size: 14pt mso-bidi-font-family: Calibri mso-bidi-language: AR-SA mso-fareast-font-family: Calibri mso-bidi-theme-font: minor-latin">: In this in-vitro study, </span><span style="line-height: 150% font-size: 14pt mso-bidi-font-family: Calibri mso-bidi-theme-font: minor-latin">seventy lithium </span><span style="line-height: 150% font-size: 14pt mso-bidi-font-family: Calibri mso-bidi-language: AR-SA mso-fareast-font-family: Calibri mso-bidi-theme-font: minor-latin">disilicate ceramic</span><span style="line-height: 150% font-size: 14pt mso-bidi-font-family: Calibri mso-bidi-theme-font: minor-latin"> (Empress 2) specimens (16 mm in diameter and 1.5 mm thick) were prepared and divided into 7 groups (n=10).
