Post-restoration sensitivity is a common challenge in dentistry. This video offers valuable insights into preventing sensitivity through effective adhesive protocols.
The key lies in understanding the interaction between phosphoric acid, dentin, and enamel. Phosphoric acid demineralizes dentin by dissolving hydroxyapatite and exposing collagen fibrils. However, excessive conditioning can lead to adhesive failures, as adhesive penetration is limited to about 5-6 micrometers, while over-conditioning can demineralize up to 13-14 micrometers.
To minimize sensitivity, consider using self-etch adhesives like Clearfil SE Bond. These adhesives demineralize and penetrate dentin simultaneously, reducing the risk of incomplete adhesive penetration. For optimal results, a selective etching technique is recommended, applying phosphoric acid only to enamel for 20-30 seconds before using the adhesive system.
Clearfil SE Bond by Kuraray is an excellent example of a two-step adhesive system that provides reliable results. Transitioning to such systems can significantly improve outcomes, reducing sensitivity and ensuring durable restorations.
