Rugoscopy is the study of the patterns and characteristics of the ridges and grooves on the inner surface of the human palate, specifically the hard palate. These unique patterns can be used for personal identification, similar to fingerprints, due to their distinctiveness among individuals. Rugoscopy has applications in forensic science and anthropology, allowing for the analysis of dental and skeletal remains. Additionally, it may provide insights into certain medical conditions and genetic traits associated with palatal morphology.
