A Comparison of Linear Enamel Hypoplastic Defects between Two Pre-Columbian Peruvian Samples Using Scanning Electron Microscopy
Interruptions to amelogenesis (enamel formation) are expressed on the tooth surface as horizontal grooves known as linear enamel hypoplastic (LEH) defects. When combined with other indicators of physiological stress, LEH defects can assist bioarchaeologists with the reconstruction of overall health in archaeological populations. This research compares dental casts from two Pre-Columbian Peruvian sites: Rinconada Alta (Yschma culture) on the Central coast and Chiribaya Baja (Chiribaya culture) on the Southern coast. Using scanning electron microscopy, LEH defects were observed in both samples to assess the duration and frequency of childhood stress between the two sites.
