Abstract

Objective:

This randomized controlled clinical study aimed to evaluate the one year clinical performance of single shade universal resin composites in Class II restorations according to the World Dental Federation (FDI) criteria.

Materials And Methods:

A total of 180 Class II restorations were placed in 62 patients using four different single-shade universal composites (Charisma Diamond One, Vittra APS Unique, Omnichroma, and Zenchroma) and one conventional composite (Clearfil Majesty Posterior), randomly assigned via random.org. Enamel margins were selectively etched with phosphoric acid, followed by application of Scotchbond Universal Plus adhesive. Clinical evaluations were performed at baseline (1 week), 6 months, and 12 months by two independent examiners according to the FDI criteria (scores 1-5). Data were analyzed using the Shapiro-Wilk test (p < 0.05), Friedman test, and Kruskal-Wallis test (α = 0.05).

Results:

All materials demonstrated clinically acceptable performance over 12 months in terms of fracture/retention, marginal adaptation, proximal contact, occlusion, wear, secondary caries, tooth integrity, postoperative sensitivity, and surface texture (p > 0.05). Only Charisma Diamond One maintained color stability without significant changes (p > 0.05), whereas the other materials exhibited statistically significant deterioration in color matching and marginal staining (p < 0.05). Intergroup differences were observed only in the color match parameter at 6 and 12 months (p = 0.001).

Conclusion:

Within the limitations of this study, single-shade universal composites demonstrated satisfactory one-year clinical performance and may be considered effective alternatives to conventional composites in Class II restorations.

Clinical Relevance:

Single-shade composites provide a simplified yet clinically reliable approach for posterior restorations.

Classification and Mechanical Properties of Synthetic Polymers

Classification and Mechanical Properties of Synthetic Polymers

Synthetic polymers are classified as elastomers, fibers, or plastics based on their crystallinity. Crystallinity, the degree of long-range order in the solid state, influences the mechanical properties (stretching or contracting) of elastomers. Elastomers are flexible polymers that can expand or contract easily upon the application of an external force. They have numerous crosslinks that pull them back into their original shape when stress is removed. Silicones, for instance, are highly elastic...

Drug Product Performance: In Vitro–In Vivo Correlation

Drug Product Performance: In Vitro–In Vivo Correlation

In pharmaceutical development, it's crucial to establish a predictive in vitro–in vivo correlation (IVIVC) for two or more formulations to gain a comprehensive understanding of release properties. IVIVC reduces the need for costly in vivo studies and facilitates the establishment of meaningful dissolution specifications with significant cost savings and decreased regulatory burden. Furthermore, a meaningful IVIVC should predict Cmax and AUC within 20%, aligning with FDA guidance while adhering...
