We do, however, automatically collect some data about your visit to help us better understand how visitors use the website and how to improve the site and related resources.

How NIDCR Collects Information 

The NIDCR website uses Google Analytics measurement software to collect the information in the bulleted list in the Types of Information Collected section above. Google Analytics collects information automatically and continuously. No personal information is collected. NIDCR staff conduct analyses and reports on the aggregated data from Google Analytics. The reports are only available to NIDCR managers, members of the communications and web teams and other designated staff who require this information to perform their duties.

NIDCR uses the American Customer Satisfaction Index (ACSI) online survey to collect opinions and feedback from a random sample of visitors.  Information gathered from the survey is completely anonymous and is used to improve our site.  Participation in the customer satisfaction survey is completely voluntary, and failure to respond will not affect your ability to access information on  The survey reports are only available to NIDCR managers, members of the communications and web teams, and other designated staff who require this information to perform their duties.

NIDCR retains the data from Google Analytics and ACSI survey results as long as needed to support the mission of the NIDCR.

How NIDCR Uses Cookies 

The Office of Management and Budget Memo M-10-22, Guidance for Online Use of Web Measurement and Customization Technologies, allows Federal agencies to use session and persistent cookies.

What is a Session Cookie?

A session “cookie” is a small piece of text generated by a web server and temporarily placed on your computer when you visit a website. A session cookie improves your experience on the site by letting the server know that you are connected and continuing your visit to the site.  Session cookies do not collect any personal information about you.  When you close your browser, the session cookies are deleted from your computer. This means the next time you visit the website, it will not “recognize” your computer or have information about any of your past visits to the NIDCR site.

The OMB Memo 10-22 Guidance defines our use of session cookies as "Usage Tier 1 - Single Session."  The policy says, “This tier encompasses any use of single session web measurement and customization technologies.”

What is a Persistent Cookie?

A persistent cookie is also a small piece of text generated by a web server and placed on your computer when you visit a website. Unlike session cookies, persistent cookies are stored on your computer for longer periods.

NIDCR uses persistent cookies to enable Google Analytics to differentiate between new and returning visitors.  Persistent cookies remain on your computer between visits to the NIDCR website until they expire or are deleted by the computer owner.

We also use persistent cookies to ensure you do not receive repeated invitations to take the American Customer Satisfaction Index (ACSI) survey.  Unless you delete them, the persistent cookies will reside on your computer for 30 days. Persistent cookies will not collect or retain any personal information about you or reveal whether you responded to the survey.

The OMB Memo 10-22 Guidance defines our use of persistent cookies as “Usage Tier 2—Multi-session without Personally Identifiable Information (PII).” The policy says, “This tier encompasses any use of multi-session Web measurement and customization technologies when no PII is collected.”

How to Opt Out or Disable Cookies

If you do not wish to have session or persistent cookies placed on your computer, you can disable them using your web browser. If you opt out of cookies, you will still have access to all information and resources at

Instructions for disabling or opting out of cookies in the most popular browsers are located at:  Please note that by following the instructions to opt-out of cookies, you will disable cookies from all sources, not just those from

How Personal Information is Protected 

WWhen inquiries are e-mailed to us, we temporarily store questions and e-mail addresses so we can respond electronically. Unless otherwise required by statute, we do not publicly identify anyone who sends questions or comments to our website.

You may also sign up to receive our e-newsletter, text messages and notices via our website or request free oral health publications using the online publication order form. The information you provide (name and e-mail address for the e-newsletter and notices; name and mobile phone number for text messages; name, address, and telephone number for ordering publications) is used solely for the purpose of sending you our newsletter or the publications you request.

If you order publications from us, we will share your name, address, other contact information and the titles of the publications you requested with our clearinghouse, which stores and distributes publications for us. Only designated staff members or contractors requiring access to requests or forms to fulfill orders will have access to them.

The personal information you provide to us via subscription form, e-mail or through the online publication order form is retained for one year. If you receive the e-newsletter, notices or text messages, we retain your e-mail address or mobilephone number (for texts) as long as you are subscribed. 
If we store your personal information in a record system designed to retrieve information about you by personal identifier (name, personal e-mail address, home mailing address, personal or mobile phone number, etc.) so that we may contact you, we will safeguard the information you provide to us in accordance with the Privacy Act of 1974, as amended (5 U.S.C. Section 552a).
The Privacy Act says NIDCR operates a record system designed to retrieve information about you in order to accomplish its mission. A Privacy Act Notification Statement should be prominently and conspicuously displayed on the public-facing website or form that asks you to provide personal information. The notice must address the following criteria:
  • NIDCR legal authorization to collect information about you
  • Purpose of the information collection
  • Routine uses for disclosure of information outside of NIDCR
  • Whether the request made of you is voluntary or mandatory under law
  • Effects of non-disclosure if you choose to not provide the requested information

We are very interested in what you have to say. If you write to us or ask us a question, we use the e-mail address from your message to respond to you. It is up to you whether or not you tell us who you are. But please make sure it is okay with a parent or guardian before you do—and any other time you provide information online.
