Are DNA test results affected by dental cadaver bone?

No Effect on Blood or Saliva DNA: Cadaver bone grafts do not alter your own DNA in blood, saliva, or buccal (cheek) swab samples—these are the standard sources for DNA testing.

Non-Living Tissue: Donor bone used in grafts is sterilized and deproteinized, meaning it does not contain viable cells or donor DNA that could interfere with testing.

Localized Use Only: Bone grafts stay confined to the surgical site (e.g., jawbone) and do not integrate into the body’s genetic system.

DNA Testing Remains Accurate: Tests such as paternity, ancestry, or genetic screening based on saliva or blood remain completely reliable even after a bone graft.

Forensic vs. Clinical Context: In forensic cases (e.g., identifying remains), foreign graft materials may be noted, but they don’t change the individual’s genetic identity.

Medical Disclosure Recommended: While it doesn't affect test accuracy, it’s wise to inform labs or clinicians about recent grafts for full medical context during advanced or forensic analyses.
