Summary
The clinical performance of a multimode adhesive in noncarious cervical lesions showed no significant differences in retention based on bonding strategy after 18 months. Evaluation criteria impacted the assessment of marginal adaptation, with FDI criteria proving more sensitive than USPHS criteria.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Clinical Trials
Background:
- Noncarious cervical lesions (NCCLs) are prevalent dental defects requiring effective restoration.
- Multimode adhesives offer versatile bonding options for various clinical scenarios.
- Evaluating long-term clinical performance is crucial for understanding adhesive efficacy.
Purpose of the Study:
- To assess the 18-month clinical performance of a specific multimode adhesive (Scotchbond Universal Adhesive) in NCCLs.
- To compare the outcomes of four different bonding strategies: etch-and-rinse on moist dentin (ERm), etch-and-rinse on dry dentin (ERd), selective enamel etching (Set), and self-etch (SE).
- To evaluate restoration success using both World Dental Federation (FDI) and United States Public Health Service (USPHS) criteria.
Main Methods:
- A total of 200 restorations were placed in 39 patients using four distinct bonding protocols.
- Composite resin restorations were incrementally placed and evaluated at baseline and 18 months.
- Standardized clinical evaluation criteria (FDI and USPHS) were employed to assess restoration integrity and marginal adaptation.
Main Results:
- Restoration retention rates were comparable across all four bonding groups after 18 months (p>0.05).
- Marginal staining and adaptation varied between groups, with FDI criteria revealing more discrepancies than USPHS criteria.
- The self-etch (SE) group showed a significantly higher percentage of marginal discrepancy when assessed with semiquantitative scores (SQUACE).
Conclusions:
- The choice of bonding strategy did not significantly influence the 18-month clinical retention of the multimode adhesive in NCCLs.
- Differences in marginal adaptation were observed, highlighting the greater sensitivity of FDI criteria compared to USPHS criteria.
- The study underscores the importance of selecting appropriate evaluation criteria for assessing restorative material performance.

01:14Adhesion
Adhesion occurs when one type of molecule is attracted to a different molecule. Water exhibits adhesive properties in the presence of polar surfaces, such as glass or cellulose in plants. For instance, when water is poured into a glass, the positively charged hydrogen molecules of water are more attracted to the negatively charged oxygen molecules in the silica than to the oxygen in neighboring water molecules.
Capillary action is a result of water’s adhesive tendencies. When a narrow glass...

Product specifications define the acceptable quality of a pharmaceutical product by ensuring identity, purity, potency, and strength. These specifications serve as benchmarks during development, manufacturing, and post-approval quality control. Clinically relevant specifications are particularly important because they directly relate to a drug's safety and efficacy in clinical use.Dissolution studies are critical biopharmaceutic tools that link in vitro behavior to in vivo performance.
