LABORATORY METHODS OF RESEARCH OF ADHESIVE SYSTEMS

Area of Science:

• Dental Materials Science
• Adhesive Dentistry

Background:

• Adhesive systems are crucial for modern dental restorations.
• Understanding the properties of different generations of adhesive systems is vital for clinical success.

Purpose of the Study:

• To evaluate the sealing effectiveness of V and VII generation adhesive systems.
• To compare curing depth, water absorption, and water solubility of these systems.

Main Methods:

• Laboratory study conducted per ISO/TS 11405:2015.
• Tested adhesive systems: V generation ('DC Adhesive NF') and VII generation ('Single Bond Universal').
• Measurements included curing depth, water absorption, and water solubility using precision instruments.

Main Results:

• V generation adhesives exhibited an average curing depth of 4.08mm, while VII generation showed 3.51mm.
• Average water absorption was 45.97 μg/mm³ for V generation and 30.89 μg/mm³ for VII generation.
• Average water solubility was 6.94 μg/mm³ for V generation and 4.17 μg/mm³ for VII generation.

Conclusions:

• Both V and VII generation adhesive systems are suitable for restoring hard tooth tissues.
• V generation is recommended for closed defects with minimal oral fluid exposure.
• VII generation is suitable for open restorations, gingival areas, and constantly moist environments.
