California Dental Waterline Requirements
Business and Professions Code 1680(ag) addresses sterile or recognized disinfecting/antibacterial irrigation for procedures on exposed dental pulp.
Published by LineTabUpdated Sources checked
What the cited provision requires
| Requirement | Details |
|---|---|
| What the statute covers | Procedures performed on exposed dental pulp. SB 1491 made the use of irrigation water that is not sterile, or that does not contain recognized disinfecting or antibacterial properties, unprofessional conduct. |
| What it does not cover | This provision does not itself set a general waterline testing interval. It is not a complete survey of other California infection-control obligations. |
| Practical effect | Pulpotomies and similar pulp-exposing procedures cannot be irrigated with untreated dental unit water. CDC's 500 CFU/mL recommendation still applies as standard of care for everything else. |
Apply the requirement to your practice record
- Identify procedures involving exposed pulp and the irrigant requirement in the current provision.
- Document the appropriate product and delivery instructions for each relevant procedure.
- Keep sterile surgical irrigation distinct from ordinary chair-water monitoring.
- Confirm other applicable California board infection-control requirements directly; this provision alone is not a full compliance program.
