    Comparative study of two adhesive systems on the post operative sensitivity of restorations with composite resin in the posterior sector
    (Universidad Privada Norbert Wiener, 2024-06-21) Casiano Espinoza, Paul Nazir; Gómez Carrión, Christian Esteban
    The objective of this study was to determine the differences in the effectiveness of two adhesive systems on postoperative sensitivity of composite resin restorations in the posterior sector. A quasi-experimental, quantitative, and longitudinal methodology was used, with a sample of 60 patients requiring simple Class I restorations according to the Black classification. The results revealed that the effectiveness of postoperative sensitivity of restorations, according to the EVA scale, in the 4th generation system showed a sensitivity mean of 0.03 at 24 hours, increasing to 0.08 after one week, and decreasing to a mean of 0.0 after one month. In contrast, the universal system showed a sensitivity mean of 0.17 at 24 hours, increasing to 0.53 after one week, and slightly decreasing to a mean of 0.47 after one month. However, the statistical analysis showed that the p-value was 0.02, which is lower than the alpha value, thus rejecting the null hypothesis (Ho). With a 95% confidence level, it can be concluded that there is a significant difference in the effectiveness of the two adhesive systems on postoperative sensitivity of composite resin restorations in the posterior sector.
