Tamaño dental, desgaste oclusal y microestriación en primates Hominoidea

Abstract

El patrón de microestriación dentaria depende no solo de la composición de los alimentos ingeridos, sino también de la presencia en ellos de polvo, cenizas u otras partículas abrasivas de origen externo, generalmente incorporadas al alimento durante su preparación. El presente estudio analiza cómo se ve afectado el patrón de microestriación de la superficie vestibular de los dientes por factores independientes a la estructura y composición alimentaria, como son el tamaño de la pieza dentaria y el desgaste oclusal de la misma. Se han analizado moldes dentarios obtenidos de ejemplares originales de colecciones osteológicas de molares de primates Hominoideos, en los que se ha medido el patrón de microestriación dentaria de todos los individuos, así como el tamaño dental (área oclusal total- AOT) y el desgaste oclusal (porcentaje de exposición de dentina- PED) mediante técnicas semiautomáticas de análisis cuantitativo. Los resultados obtenidos indican que el tamaño dentario y el grado de desgaste oclusal de los molares analizados no están correlacionados con el patrón de microdesgaste dental de sus superficies vestibulares. Ello sugiere que las actividades masticatorias asociadas con las superficies oclusales de los molares no están directamente relacionadas con la capacidad abrasiva del alimento, sino con utilización de la superficie occlusal de la dentición en actividades que no repercuten en el patrón de microestriación de las superficies vestibulares de los dientes.
