DESENSITIZER
BISBLOCK
Oxalate Dentin Desensitizer
BISCO’s patented* oxalate dentin desensitizer and its unique application
technique are designed to prevent intra-tubular fluid movement which causes
dentin sensitivity (hydrodynamic theory---Brännström, 1966).
When BisBlock is applied on dentin, after surface decalcification (by acid etching and rinsing), calcium
oxalate crystals are formed only within the tubules (SEMs shown). This results in the blockage of
dentinal fluid movement and eliminates sensitivity, while leaving the dentin surface unobstructed to
readily accept adhesive for ideally bonded restorations.
* U.S. Patents: 6,406,529 and 6,506,055 by Pashley et al.
BENEFITS
Deep penetration into the dentinal tubules to effectively BLOCK dentinal fluid movement
Resists dislodging caused by toothbrush abrasion. Excellent bond strength still achieved.
Yellow colour of solution aids placement to ensure complete coverage
Safe for patient’s tissue and pulp

BISBLOCK FAQ’s
Q: Why can’t BisBlock be used with Self-
Etching primers
A: Acidic self-etching products and acidic
adhesives will partially dissolve the calcium
oxalate crystals and reduce bond strengths.

Cross Section View
Left, SEM top view, using a patented technique, BisBlock reacts with calcium ions in 30 seconds to form
calcium oxalate crystals in the dentinal tubules, but not on the surface. Right, SEM cross section view,
oxalate crystals within tubules halt dentinal fluid movement and cannot be mechanically dislodged, thus
preventing sensitivity. SEM courtesy of David Pashley, D.M.D., Ph.D.
Results of Past Attempts
• Crystals formed to cover the surface of the dentin
tubules which blocked fluid movement, but were easily
dislodged by brushing, flossing, etc., This resulted in
returned sensitivity a short time later.
• Bond strengths were drastically reduced due to crystal
formations blocking adhesive penetration into the tubules.
Q: What happens if I use a Self-Etching
Primer/Adhesive or a highly acidic adhesive
A: Bond strengths will be drastically reduced.
Q: What is the shelf life of BisBlock
A:2 Years.
Q: How many applications in one bottle
A: Bottle yields approximately 145 drops.
Depending on the procedure, the number of
applications will vary.
Q: I am not planning on anesthetizing my
patient prior to using BisBlock. How may I
maximize patient comfort
A: The etch, water, BisBlock and the adhesive
may be warmed to body temperature
