Rugoscopy: A Diagnostic Appurtenance for Malocclusion or just a Forensic Aid? - A Pilot Study

چکیده
Transverse palatine folds or palatal rugae (PR), are asymmetrical and irregular elevations of the mucosa in the anterior third of the palate arranged in a transverse direction on each side of the medial palatal raphae and behind the incisive papilla (IP), located in the mid-sagittal plane [1,2]. Developmentally, palatal rugae are formed in the third month in utero from the hard connective tissue covering bone. First PR were identified in human embryos of 32-mm Crown-rump length (CRL) next to IP [3]. The orientation pattern is formed by about 12th to 14th week of prenatal life and remains stable until the oral mucosa degenerates after death [4,5]. The prominence of PR diminishes from prenatal period to adolescence but the shape remains unaltered [6].
