Palatal rugae are the asymmetrical and irregular elevations of the mucosa.
The SEM of the embryonic whorls of Helminthoglypta greggi shows ornamentation with rounded elongated papillae arranged in apically ascending, well-spaced, rather ill-defined, spiral rows separated by cross-rows of numerous short rugae. (Fig.
Studying additional biometric traits such as the palatal rugae pattern to differentiate between identical twins is an important focus in biometrics and forensic odontology [14].

They were divided into two distinct population groups: Group A (edentulous patients with full upper removable dentures), Group B (dentulous without upper removable partial dentures), which underwent examination of the forms of the palatal rugae using the method described by Martins-dos-Santos (1946), in order to verify the applicability and possibilities of success in examining the edentulous and dentulous arches.
