How does short-term exposure to chloramine-T solution affect the bonding performance of chemical-cured adhesives?

Label:chem

Topic
Chloramine-T is commonly used as a storage solution for extracted human teeth in dental research. However, its potential impact on the bonding performance of dental adhesives, especially chemical-cured ones, is not fully understood.
Answer
Short-term exposure to a 0.5% chloramine-T solution significantly reduces the microtensile bond strength (μTBS) of the chemical-cured adhesive Bondmer Lightless, decreasing it from 22.62 MPa to 12.87 MPa after a 5-minute immersion. This suggests that chloramine-T may interfere with the interaction and sealing between the adhesive resin and dentin in chemical-cured adhesives.
