    Dental Anthropology

    Uploaded by

    Forense Estomatologia
    Dental anthropology examines teeth as an alternative source of information about the past. Teeth can provide insights into biological relatedness, age, sex, diet, health, disease patterns, and cultural behaviors of past populations. Dental anthropology studies include analyzing bitemarks, occlusal wear patterns, dental records, tooth measurements, non-metric traits like shovel-shaped incisors, and evidence of diet, nutrition, and cultural modifications from teeth. Teeth also preserve evidence of health conditions like dental caries, periodontal disease, and enamel defects that can inform our understanding of past populations.
