Resin bonding to wet substrate. 1. Bonding to dentin
Quintessence International (Berlin, Germany : 1985)
|January 1, 1992
Summary
This study found that the All-Etch/All-Bond dentin-enamel bonding system achieved higher bond strengths on wet dentin compared to dry dentin. Wet surfaces allow for more intimate adaptation of the bonding agent.
Area of Science:
- Dental Materials Science
- Adhesive Dentistry
Background:
- Effective bonding to dentin is crucial for the longevity of dental restorations.
- Dentin surface moisture can significantly influence the performance of bonding systems.
Purpose of the Study:
- To evaluate the bonding efficacy of the All-Etch/All-Bond system on both wet and dry dentinal substrates.
- To compare bond strengths achieved under different dentin moisture conditions.
Main Methods:
- An in vitro study was conducted using the All-Etch/All-Bond system.
- Dentin surfaces were conditioned with 10% and 37% phosphoric acid.
- Bond strengths were measured on both wet and dry dentinal surfaces.
Main Results:
- Wet dentinal surfaces demonstrated significantly higher bond strengths compared to dry surfaces.
- The All-Etch/All-Bond system showed superior performance on moist dentin.
Conclusions:
- The All-Etch/All-Bond system exhibits enhanced bonding to wet dentin.
- The resin-primer mixture's behavior facilitates more intimate adaptation to wet dentinal surfaces.
