Q1. What are the clinical indications for TOKUYAMA UNIVERSAL BOND?
A1. The clinical indications for TOKUYAMA UNIVERSAL BOND are:
- Direct anterior and posterior restorations with light-curing, dual-curing, and self-curing composite materials
- Intraoral repair of composite restorations, porcelain fused to metal, metal, and all-ceramic restorations without an additional primer
- Cementation of indirect restorations and veneers when combined with light-cure, dual-cure, and self-curing resin cements
- Bonding of core build-ups made of core build-up materials
- Bonding of denture resin to metal base, clasp or attachment
- Repair of denture with metal base, clasp or attachment
- Bonding of opaque resin to a metal base in the fabrication of resin-faced stainless steel crowns
Q2. What etching techniques can be used with TOKUYAMA UNIVERSAL BOND?
A2. TOKUYAMA UNIVERSAL BOND can be used with Self-etch, Selective-enamel-etch and Total-etch techniques.
Q3. Which surfaces can be bonded with TOKUYAMA UNIVERSAL BOND?
A3. TOKUYAMA UNIVERAL BOND can bond the following surfaces: tooth (dentin and enamel), glass-ceramics (porcelain), oxide-ceramics (zirconia and alumina), metals (precious and non-precious) and resin materials including inorganic filler, without the need of extra primer.
Q4.To which kind of material is TOKUYAMA UNIVERSAL BOND compatible?
A4. TOKUYAMA UNIVERSAL BOND is compatible to light-cured, self-cured and dual-cured dental materials without the need of a dual-cure activator.
Q5. Does TOKUYAMA UNIVERSAL BOND require refrigeration?
A5. Yes it does. Storage under inappropriate conditions will accelerate the degradation of TOKUYAMA UNIVERSAL BOND.
Q6. What is the shelf life of TOKUYAMA UNIVERSAL BOND?
A6. Two years after the date of production under refrigeration (0-10ºC/32-50ºF). TOKUYAMA UNIVERSAL BOND should be used by the expiration date indicated on the label of each container.
Q7. If bottle cap is left open, what happens to the integrity of TOKUYAMA UNIVERSAL BOND?
A7. TOKUYAMA UNIVERSAL BOND contains an alcohol and an acetone solvent, and they will evaporate from bottle. This will accelerate the degradation of TOKUYAMA UNIVERSAL BOND, and compromise adhesive performance.
Q8. How many drops does each bottle A or bottle B of TOKUYAMA UNIVERSAL BOND contain?
A8. Approximately 250 drops per one bottle (A/B for each one).
Q9. Do I need to shake the bottle before use?
Q10. Does TOKUYAMA UNIVERSAL BOND need to be waited after application?
Q11. Does TOKUYAMA UNIVERSAL BOND need to be light-cured?
Q12. What is the pH of TOKUYAMA UNIVERSAL BOND?
A12. The pH level of TOKUYAMA UNIVERSAL BOND after mixing is around 2.2.
Q13. What is the film thickness of TOKUYAMA UNIVERSAL BOND?
A13. 5-10 microns.
Q14. Does the layer of TOKUYAMA UNIVERSAL BOND affect the film thickness of resin cement?
A14. No, it does not. Because the layer of TOKUYAMA UNIVERSAL BOND is only 5-10 microns.
Q15. What is TOKUYAMA UNIVERSAL BOND’s working time after mixing?
A15. Complete the application within 3 minutes of dispensing when using disposable mixing well.
Q16. What if TOKUYAMA UNIVERSAL BOND dropped on the mucosal membrane?
A16. Wipe the affected area immediately. And thoroughly flush with water after restoration. Affected areas may whiten due to protein coagulation but will disappear within 24 hours.
Q17. Does TOKUYAMA UNIVERSAL BOND have fluoride release?
A17. Yes. TOKUYAMA UNIVERSAL BOND release fluoride, but not gradually.
Q18. Will the liquid of TOKUYAMA UNIVERSAL BOND cause phase separation?
A18. No, TOKUYAMA UNIVERSAL BOND will not cause phase separation even if the solvent is evaporated because TOKUYAMA UNIVERSAL BOND contains hydroxyethyl methacrylate (HEMA) which is relatively hydrophilic and improve compatibility between water and monomer.
Q19. Can I use TOKUYAMA UNIVERSAL BOND to treat hypersensitive teeth?
A19. No. You can’t use.
