What This Test Measures

The test evaluates concentrations of specific substances in your blood that can indicate underlying metabolic, hormonal, or nutritional influences on tooth growth. These biomarkers may include growth factors, vitamins, minerals, or other proteins linked to skeletal development.

Why It’s Done

Your healthcare provider may order this test if you or your child are experiencing delayed tooth eruption, unusual dental patterns, or suspected systemic conditions affecting bone or growth development.

Common Uses

This test is typically used in pediatric dentistry or orthodontics to identify potential developmental delays or conditions that could impact dental health, such as genetic syndromes or metabolic disorders.

Sample Collection

A blood sample is drawn from a vein in your arm. The sample is collected in a tube and sent to a lab for analysis. You may feel slight discomfort, but it usually takes a few minutes to complete.
