ABSTRACT
This study evaluates the non-carious cervical lesions (NCCLs) and the occlusal tooth wear in a pre-Columbian sample (n= 67, adults) from San Pedro de Atacama (North of Chile, 400-1300 BCE). The cervical regions of tooth were observed for loss of enamel and/or dentine in order to identify them as NCCLs and the tooth wear was characterized by the Basic Erosive Wear Examination (BEWE) index. None of the individuals analyzed presented NCCLs, whereas the 98.5% (66/67) of them showed occlusal wear. The mean BEWE index was 2.5, indicating severe dental wear (3 being the highest possible score of BEWE). This lack of relation among severe tooth wear and NCCLs gives support to the idea of loss of crown height reduces cervical stress and develop of NCCLs in archaeological populations.
RESUMEN
Este estudio evalúa las lesiones cervicales no cariosas (NCCLs) y el desgaste dental oclusal en una muestra precolombina (n= 67, adultos) de San Pedro de Atacama (Norte de Chile, 400-1300 AEC). Se analizó la perdida de esmalte y/o dentina en las áreas cervicales de los dientes con el propósito de identificarlas como NCCLs y el desgaste dental fue evaluado según el índice Basic Erosive Wear Examination (BEWE). Ninguno de los individuos analizados presentó NCCLs, mientras el 98,5% (66/67) de ellos mostró desgaste oclusal. El promedio del índice BEWE fue de 2,5, indicando severo desgaste dental (siendo 3 el puntaje más alto posible). La falta de relación entre severo desgaste dental y NCCLs apoya la idea que la pérdida de altura de las coronas reduce el estrés cervical y el desarrollo de NCCLs en poblaciones arqueológicas.
