The research aims to evaluate the micro shear bond strength of the calcium silicate cement (Biodentine) and the glass ionomer cement (GIC) to dentine. The study was performed using upper or lower premolars, and samples were divided into six equal subgroups according to the time period (3 h, 1 day, 1 week, 2 weeks, 4 weeks, 8 weeks), in order to study changes in the values of shear bond strength with time. The comparative study showed that the success rate of adhesion in the Biodentine group was smaller than that in the GIC group for the tested premolars after 3 hours and one day, whereas the success rate in the Biodentine group was greater than that in the GIC group for the tested premolars after 8 weeks. Results showed a positive correlation between the mean values of shear bond strengths and the studied time in Biodentine group, which ranged from 1.49 ± 0.18 MPa at 3 hours to a maximum value of 2.65 ± 0.26 MPa after 8 weeks. While there was a negative correlation between the mean values and the studied time in the GIC group and values ranged from 3.02 ± 0.13 MPa at 3 hours and 2.06 ± 0.09 MPa at 8 weeks. The study showed the advantage of Biodentine compared with GIC in terms of micro-bonding to dentine, which can have a clinically significant importance in preventing the micro leakage and reducing bacterial contamination.

A comparative study was conducted between GIC and Biodentine Cements by assessing their solubility, their effect on pH, their ability to absorb water, and calcium release in the same laboratory conditions.
The purpose of this study was to compare the shear bond strength to root dentin of a nano- ionomer material (Ketac N100,3M) and a fifth generation bonding material (Excite,Vivadent) applied with a resin composite (Tetric-ceram,Vivadent), in order to determine the material of choice for restoring root extended lesions.
An appropriate bond between glass‑ionomer and the superficial resin materials is very important for the success of sandwich technique. The aim of the present in vitro study was to evaluate the effect of three surface treatments of conventional glass‑ionomer on its shear bond strength to giomer
The aim of this study To compare in vitro shear bond strength (SBS) of different orthodontic adhesives in and rebonding metal brackets after preparing their bases mechanically. Material and methods:Sample consisted of 40 extracted first premolars, randomly divided into two groups (n=20),.Adhesive removed by tungsten carbide bur later the brackets were rebonded. The tests were performed in a tecnotest (6kN) SBS testing machine, at a speed of 1 mm/min. It was found that the mean shear bond strength of Reseliencewas 19.25 MPa and that of Heliosit orthodontic was 10.25MPa.We foundthat the mean shear bond strength of rebonding forReselience was 13.70 and 7.95 forHeliosit.The t-test revealed that there was a significant difference between the shear bond strength of the two groups. We found a significant difference between bonding and rebondingfor Reselience,while there was no significant difference between bonding and rebonding for Heliosit.
The Objective is to determined whether enamel conditioning with sodium hypochlorite (5,25%) and EDTA prior to etching was increased shear bond strength of orthodontic brackets bonded with resin – modified glass ionomer. our sample consisted of 42 extracted human premolars were randomly divided into 3 groups.
