Clinical Performance of Two Resin Composite Materials in Class II Cavities in Primary Molars: An Observational Study

Composite resins have seen significant development. In pediatric dentistry, direct composite resin restorations are becoming a crucial component of conservative care. Since their initial introduction, these materials have undergone fast evolution, leading to more esthetically pleasing and long-lasting repairs. As a result, amalgam in dentistry underwent a paradigm change in favor of more tooth-structure-preserving composites.

To evaluate and compare the clinical performance of a flowable composite resin and a packable composite resin in class II direct restorations in primary molars using a self-etch adhesive system.

Two distinct restorative materials-flowable composite (G-aenial Universal Flo, GC) and packable composite (G-aenial Posterior)-were used in a total of 24 class II restorations in 24 patients. Composite resin restorations were assessed using modified United States Public Health Service (USPHS) criteria at baseline, 3, 6, and 12 months. Data were analyzed using the Chi-square test (p ≤ 0.05).

Anatomical form and color match were statistically significant in G-aenial Universal Flo at third month, and the differences between the two materials were even more noticeable at 1 year, with flowable composite maintaining 91.7% anatomical form and packable composite drastically dropping to 33.3% (p = 0.012).

When compared to G-aenial Posterior packable composite at one year, G-aenial Universal Flo flowable composite has shown superior clinical results in class II restorations for primary molars.

G-aenial Universal Flo offers superior durability, esthetics, caries resistance, and reliable performance even in moist conditions, making it ideal for restoring primary molars in children.
