One step bond strength to enamel and dentin

Area of Science:

• Dental Materials Science
• Adhesive Dentistry

Background:

• Dental adhesives are crucial for composite restorations.
• Single-bottle adhesives aim to simplify clinical procedures.

Purpose of the Study:

• To evaluate the shear bond strength of a novel one-bottle dental adhesive.
• To assess its performance under diverse clinical conditions.

Main Methods:

• Extracted human molars and incisors were used for dentin and enamel studies, respectively.
• The One-Step adhesive was applied after various etching and rinsing protocols.
• Composite cylinders were bonded, and shear bond strengths were measured.

Main Results:

• The adhesive demonstrated consistent shear bond strength to dentin, ranging from 23-29 MPa.
• Performance on dentin was comparable to its performance on etched enamel.
• Bond strength remained stable across a wide range of tested conditions.

Conclusions:

• The new one-bottle dental adhesive exhibits reliable and consistent shear bond strength.
• It offers favorable performance on both dentin and enamel substrates.
• This adhesive presents a promising option for simplified dental bonding procedures.
