Dental unit waterline antimicrobial agents' effect on dentin bond strength

Article Abstract:

Some antimicrobial agents that dentists use to sterilize waterlines may have an adverse effect on tooth restorations. Researchers bonded a composite to a dentin surface and then exposed it to distilled water, bleach, BioClear, Listerine, and Bio 2000. All the antiseptic agents reduce the strength of the bond.

The dental unit waterline controversy: defusing the myths, defining the solution

Article Abstract:

Dentists should use available technology to reduce the number of bacteria in dental waterlines. Although there have been few cases of illness linked to dental waterlines, the water should still meet the standards for regular drinking water.

Validation of an in-office dental unit water monitoring technique

Article Abstract:

The HPC Sampler may be an effective method for monitoring dental water units for bacterial contamination. Dental water units supply water for oral irrigation during dental procedures. Bacteria from municipal water can grow in these units, and may be hazardous to some patients and dental staff. Researchers compared the HPC Sampler (Millipore Corp.), an easy-to-use testing system, with standard HPC agar and R2A agar plating techniques. In 408 samples from 76 units, HPC sampler results agreed with the agar plating methods in 92.6% of tests, sufficiently accurate for reliable testing.
