Short-term DC values (%) obtained through real-time kinetics measurements using the conventional curing protocol ranged from 50.5 to 64.4 in the CG and from 44.4 to 55.9 in the MBG, with the highest value observed for Enlight (10 min) in the CG and the lowest for Enlight (2 min) in the MBG. Under the rapid curing protocol, short-term DC values were significantly lower (\(p<0.001\)) across all materials in both groups, ranging from 45.8 to 60.0 in the CG and from 43.0 to 50.1 in the MBG (Figure 2). The greatest differences in short-term DC under rapid curing, compared to conventional curing, were observed for Enlight in the CG (4.4%) and Heliosit in the MBG (up to 5.9%) (Figure 3). The 24 h DC values were consistently higher than the short-term values for all materials and protocols (Figure 4). For the conventional curing protocol, the 24 h DC values ranged from 56.7 to 82.8 in the CG and from 54.4 to 82.7 in the MBG, with Enlight showing the highest values in both groups. Rapid curing resulted in lower 24 h DC values across all materials (\(p\) = 0.001-0.012), except for Transbond XT in the CG, where no significant difference was observed (\(p\) = 0.244). For the rapid curing protocol, the 24 h DC values ranged from 54.8 to 81.4 in the CG and from 49.7 to 79.0 in the MBG. The differences between rapid and conventional curing in the 24 h DC values were smaller than those observed in the short-term DC values, varying from 0.5% to 1.9% in the CG and from 1.7% to 4.7% in the MBG, with the greatest difference seen in Heliosit (Figure 5).

Figure 2: DC values for Enlight, Heliosit, and Transbond XT at 2, 6, and 10 min. Statistically significant differences (\(p\) < 0.05) between curing protocols are indicated with asterisks (*). Rapid curing mode was associated with increased inter-sample variability for short-term measurements (Figure 6), ranging from 0.9% to 3.6%, in comparison to conventional curing, which demonstrated variability between 0.8% and 1.5%. Heliosit and Transbond XT in the MBG showed the highest levels of variability, particularly at the 2 min time point (3.1% and 3.6%, respectively). Coefficients of variability were similar in the 24 h DC measurements, ranging from 0.8% to 1.7% for the conventional protocol and 0.8% to 1.8% for the rapid curing protocol (Figure 7).

The partial eta-squared values describing relative effect size of the factors \"Material,\" \"Bracket,\" and \"Curing protocol\" for both short-term and 24 h DC and \"Time point\" for short-term DC are presented in Tables 2 and 3. Partial eta-squared is a measure of effect size that quantifies the proportion of total variance in the dependent variable that is attributable to a specific factor. It reflects relative effect sizes of each factor and provides information about practical significance. This information complements the \(p\)-value (which indicates only statistical significance regardless of the effect size) by enabling evaluation of whether a statistically significant effect is also meaningful in magnitude. According to [PERSON]'s guidelines, \(\eta^{2}>0.14\) indicates a large effect. Thus, all of the investigated factors exhibited large effects on DC outcomes.
