Terms of Use / clinical disclaimer
Terms of Use & Clinical Disclaimer
ORAD ranks radiographic possibilities to support a clinician's differential. It is decision support, not diagnosis. It does not diagnose, it is not a medical device, and every output requires independent professional judgment.
Scope & acceptance
These terms govern use of the ORAD reference site, the differential-diagnosis workspace, and related tools other than the experimental tools described below (collectively, "ORAD"). ORAD is intended for use by qualified dental and medical professionals for education and clinical decision support. By using ORAD you acknowledge the limitations described below. If you do not agree, do not use ORAD.
Decision support, not a diagnostic device
ORAD ranks candidate lesions by posterior probability from the findings you provide, using a Bayesian method over curated characteristic distributions. It is an aid to the clinician, not a substitute for professional judgment. ORAD does not diagnose, does not recommend treatment, and is not a medical device; it is not cleared or approved by any regulatory authority for diagnostic use. A ranked differential is a set of possibilities to consider, not a determination that any lesion is present or absent.
Experimental tools
Some tools are marked experimental and require a separate acceptance before use. Experimental tools are not FDA cleared or approved by any regulator and are not for diagnosis or treatment. Do not use them to diagnose, plan treatment for, or treat any patient. They are research and education tools that may show wrong images or measurements.
No warranty, Limitation of liability, and Acceptable use apply to experimental tools as they do to ORAD. Experimental tools sit outside the "ORAD" definition in Scope & acceptance, so the "not a medical device" statement in Decision support, not a diagnostic device does not apply to them.
No patient-specific diagnosis or treatment advice
ORAD does not provide patient-specific diagnosis, treatment advice, or a replacement for clinician judgment. Any clinical decision (including diagnosis, further imaging, biopsy, referral, or treatment) remains the sole responsibility of the treating clinician, who must correlate ORAD's output with the full clinical picture, history, and their own examination.
Image-recognition limitations
Where ORAD proposes findings from a radiograph, those proposals are assistive only and carry no diagnostic weight until confirmed or corrected by the clinician. Automated image analysis can misread or miss features; proposed values are a starting point for your review, never a conclusion. You must confirm or correct each film-derived finding before relying on any resulting differential.
No warranty
ORAD is provided "as is" and "as available," without warranties of any kind, express or implied, including any implied warranties of merchantability, fitness for a particular purpose, accuracy, or non-infringement. ORAD's content is derived from literature and expert review and may be incomplete, out of date, or contain errors. No guarantee is made that ORAD will be uninterrupted, secure, or error-free.
Limitation of liability
To the maximum extent permitted by law, ORAD, its authors, and the UCLA School of Dentistry are not liable for any direct, indirect, incidental, consequential, or other damages arising from use of (or inability to use) ORAD, including any clinical decision made in reliance on its output. You use ORAD at your own professional discretion and risk.
Acceptable use
Use ORAD only for lawful, professional, educational, and decision-support purposes. Do not enter protected health information beyond what is necessary, and do not represent ORAD's output as an autonomous or definitive diagnosis to patients or third parties. Do not attempt to disrupt, reverse-engineer for misuse, or overload the service.
Changes & contact
These terms may be updated as ORAD evolves; the effective date below reflects the current version. For questions about these terms, contact the ORAD team.
