Effects of chemical surface pretreatments on the surface roughness and shear bond strength of fiber post-resin cement interfaces: a preliminary <i>in vitro</i> study.

ABSTRACT:

Background

This preliminary study evaluates the impact of different chemical surface pretreatments on the surface roughness (Ra) of fiber posts and the shear bond strength (SBS) at the interface between the horizontal surface of fiber posts and resin cement, highlighting an area that has not been extensively researched.

Methods

Fifty glass fiber posts (Cytec Blanco, Hahnenkratt) were used, and polishing discs were employed to create a horizontally flat surface. Their dimensions were standardized using a digital caliper and divided into two pieces from each post (n = 20). The experimental groups included different pretreatment protocols: Group I (Control) had no pretreatment, Group II used 4% hydrofluoric acid (HF) (Porcelain Etchant, Bisco), Group III used 9.6% HF (Po
