What This Test Measures

The X-ray captures images of your tooth’s root and surrounding bone, focusing on the root apex (tip) to assess its development. This includes checking for signs of root formation, bone density, and whether the tooth is fully erupted or still developing.

Why It’s Done

Doctors may order this test to monitor tooth development in children, plan orthodontic treatments, or diagnose issues like delayed root formation, cysts, or infections in developing teeth.

Common Uses in Care

Typically performed during dental check-ups, especially in adolescents or patients with dental concerns like misalignment, impacted teeth, or developmental delays.

Sample Collection & Process

No blood or fluid sample is taken—this is a purely radiographic procedure. A dental professional places a sensor near your mouth to capture clear images of your tooth roots.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
