Explanation

Wavy palatal rugae are the MOST common pattern in the general population, followed by curved, straight, and circular patterns. Palatal rugae are unique to each individual, stable throughout life (except in length due to growth), and resistant to decomposition and fire. They are used in forensic identification when dental records or fingerprints are unavailable, particularly in mass disasters.
