The purpose of this study was to analyse effect of primer solution on degree of conversion two-step self-etch adhesive with a Fourier transform infrared specterometer (FTIR) deivice.

For evaluate degree of conversion, Primer and bonding agent was applied above mylar strip. In the control group, only 3.0 ㎕ of adhesive resin was used. For four experimental group, primer solution was added 0.5 ㎕ increments from 0.5 ㎕ to 2.0㎕ in adhesive resin. Dentin bonding system used in this study two-step self-etch system is Cleafil SE bond (Kuraray Medical Inc., Tokyo, Japan). And then IR spectra in uncured state and cured state of adhesive were obtained using FTIR device.

Data were analyzed by One-way ANOVA and Scheffe test. Statistical significance was set at α = 0.05.

The results were as follows: 1.There was no significant difference on DC between Group 1 and control group. 2.There were significant differences on DC between another experimental groups and control group.

In conclusion, the quantity of primer solution in some amount of variation in two-step self-etch adhesive effect DC of adhesive resin.
