The Effect of Curing Time on the Degree of Conversion of Poly-acid Modified Composite Resin (Compomer) “An In Vitro study”

Aims to evaluate the effect of light intensity on the degree of conversion of polyacidmodified composite resin. Materials and methods: Fourteen samples were prepared and divided randomly to four groups according to Light Intensity. Fourier Transform Infrared Spectrometer (FTIR) is used in order to measure the degree of conversion. Results and discussion: Analysis of variance (ANOVA) and Duncan multiple range test were used for analysis. The study showed that at 1mm depth the polyacid-modified composite resin has a difference in the degree of conversion at different inte
