Summary: | Backround: Smear layer formed during cavity preparation interfere with the
adhesion between restoration and tooth structure and is considered a barrier that
would degrade the quality of adhesion. Smear layer does not have a stable
substrate for adhesion, gradually layer dissolves in the restorative material and
cause microleakage, penetration of bacteria and inflammation of the pulp. Cavity
conditioner an acid material containing 20% polyacrylic acid and 3% aluminum
chloride is used to remove the smear layer and surface contamination on the
dentin which can reduce the adhesion of the material and the tooth surface.. The
higher the concentration, the more smear layer is dissolved in order to obtain
adhesion of glass ionomer cements better. Purpose: The purpose of this
laboratory research is to study the shear bond strength of glass ionomer cement
in dentin after application dentin conditioner and cavity conditioner Material and
Method: Twenty seven bovine cow's teeth were divided into three groups. Each
group consisted of nine samples. Group 1 was control (without conditioner).
Group 2 was treated with the Dentin conditioner. Group 3 was treated with the
Cavity conditioner. Result: The average shear bond strength in group 1 is 3.31
Mpa, group 2 is 7.74 MPa and group 3 is 9.92 Mpa. Conclusion: There is a
significant difference between third group and the shear bond strength of glass
ionomer cement on dentin with application of the Cavity conditioner is higher
than with application of the Dentin conditioner and without application
conditioner
Keywords: Glass ionomer cement, Dentin conditioner, Cavity conditioner, shear
bond strength. |
