Summary
Ormocer flowable (OF) resin demonstrated comparable bond strength to total etch (TE) cement, indicating its potential as a dental luting agent. Ormocer veneers showed comparable bond strength to ceramic veneers.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
- Restorative Dentistry
Background:
- Dental restorations require durable luting agents and veneer materials.
- Ormocer (ORMOCER) materials offer potential advantages in dental applications.
- Assessing the bond strength and failure modes of novel materials is crucial for clinical success.
Purpose of the Study:
- To evaluate the shear bond strength (SBS) of ormocer flowable (OF) resin as a luting agent.
- To compare OF resin with self-adhesive (SA) and total etch (TE) cements.
- To assess ormocer as an indirect veneer material against ceramic and analyze failure modes using SEM.
Main Methods:
- Sixty maxillary central incisors were divided into three groups based on luting cement: OF, SA, and TE.
- Groups were subdivided based on veneer material: ormocer (O) or ceramic (C).
- Specimens underwent thermocycling, SBS testing, and SEM analysis for failure modes.
Main Results:
- Ormocer flowable resin showed significantly higher bond strength than self-adhesive cement (P < 0.05).
- Highest mean bond strength for ormocer veneer was with OF (19.11 ± 1.92 MPa).
- SEM revealed mixed failure modes for OF and TE, while SA exhibited adhesive failure.
Conclusions:
- Ormocer flowable resin is as efficient as total etch cement for luting.
- Ormocer as a veneer material exhibits comparable bond strength to ceramic.
- Ormocer materials represent a promising addition to dental restorative options.

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

01:17Equivalence: In Vitro and In Vivo Bioequivalence
302
Bioequivalence studies are crucial in evaluating whether new drugs can match an approved one regarding pharmacological effects and clinical performance. These studies test if drugs, despite different dosage forms, share identical plasma concentration-time profiles. Three types of equivalence are central to these studies: chemical, pharmaceutical, and therapeutic. Chemical equivalence indicates that two or more drug products contain identical active ingredients in equal amounts. Pharmaceutical...

01:20Drug Product Performance: In Vitro–In Vivo Correlation
331
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...
