Dental Testing Requirements

Varanidex provides the annual QC testing for dental x-ray machines either by its convenient, cost effective mail service, or by having its personnel perform the testing at the dental office. More than 80% of our clients use our mail service. For further information on this service please contact us by phone or e-mail.

Acceptance Testing is required when a new (or used) machine is installed, or when a machine is moved from one location to another. This is a bit more robust than the annual requirement. Varanidex staff perform these tests at the dental office.
