Dental wear and oral pathology: possible evidence and consequences of habitual use of teeth in a Swedish Neolithic sample.

abstract：:Twenty weanling 6-month-old male squirrel monkeys were allotted to the following treatments: 1) first control animals were killed at weaning; 2) second control animals were killed when 24 months old; and 3) malnourished animals were fed on a low-protein diet and killed at age 24 months. Lateral and vertical teleradiog...
