dc.description.abstract | The purpose of this study was to investigate the effect of initiator and inhibitor concentration on the polymerization shrinkage kinetics of photo-cured experimental dental resin composites. We prepared experimental composites with different curing rates by varying the concentration of photo-initiator (Camphorquinone) and inhibitor (Butylated hydroxytoluene). During photo-activated curing, the polymerization shrinkage, maximum shrinkage rate, peak shrinkage rate time, and polymerization shrinkage stress of the experimental composites were measured using a laboratory made strain-stress analyzer for 10 minutes. The degree of conversion of cured composite was also evaluated. The results were analyzed with ANOVA and Duncan post-hoc test. The polymerization shrinkage and degree of conversion of the composites increased with increasing initiator concentration, while they did not affected by inhibitor concentration. The maximum shrinkage rate increased with increasing initiator concentration, but it decreased with increasing inhibitor concentration. The peak shrinkage rate time decreased with increasing initiator concentration, while being delayed with increasing inhibitor concentration. The polymerization shrinkage stress of the composites ranged 2.97–7.91 MPa, it increased with increasing initiator concentration. Increased inhibitor concentration reduced shrinkage stress and curing rate, without compromising the degree of conversion. | - |
