20. 3 out of over 1,400 restorations
were reported to exhibit
post-operative sensitivity
This confirms that using self-etch Adper Prompt adhesive
results in very low incidence of patient sensitivity.

21. Adper™ Prompt™ Self-Etch Adhesive
Post-op Sensitivity
Self-etching for very low incidence of post-operative sensitivity
Global clinical evaluation: Only three out of over 1,400
restorations were reported to exhibit post-operative
sensitivity
Self-etching eliminates need to use a “moist” bonding
technique, reducing technique sensitivity associated with
many one-bottle adhesives

24. Adper Prompt Self-Etch Adhesives: Strengths
• Self-etch for low post-operative sensitivity
– 3/1400 restorations sensitive in application test
• Pedodontics- with compomers or composites.
– Especially primary teeth
• Ease of application versus total etch (technique
sensitive)
versus other self-etch

25. Adper Prompt
• Less technique sensitive than other adhesives
– Moist or dry environment
• Improved chemistry
– Adhesive company - 3M ESPE synergy
– More aggressive enamel etch than Clearfil SE
– Higher microtensile bond strengths to cut enamel than
Clearfil SE
– Improved dentin bond strengths to current Prompt
