How Reliable a Bonding Strategy Is the Use of Universal Adhesives?

Area of Science:

• Dentistry
• Dental Materials Science

Background:

• Universal adhesives (UAs) emerged approximately a decade ago.
• They were developed to meet clinician needs for versatile and user-friendly dental bonding systems.
• Existing clinical research indicates that UA performance varies based on the application method.

Purpose of the Study:

• To evaluate the impact of different bonding strategies on the clinical performance of universal adhesives.
• To provide evidence-based recommendations for optimizing UA use in dental practice.

Main Methods:

• This study involved a comprehensive review of clinical trials and laboratory investigations on universal adhesives.
• Performance metrics analyzed included bond strength, marginal integrity, and clinical longevity.
• Different bonding strategies, such as etch-and-rinse, self-etch, and selective-etch, were compared.

Main Results:

• The bonding strategy significantly affects the clinical outcomes of universal adhesives.
• Certain strategies demonstrated superior bond strength and long-term stability compared to others.
• User-dependent factors and technique sensitivity were identified as critical variables.

Conclusions:

• The effectiveness of universal adhesives is not inherent but contingent upon the selected bonding strategy.
• Clinicians must carefully consider and adhere to appropriate bonding protocols for optimal results with UAs.
• Further research is warranted to elucidate the optimal bonding protocols for diverse clinical scenarios.
