All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Ages of 213 deer killed during the 1972 hunting season were determined by: (1) eruption-replacement and wear criteria in the field: (2) employing the tooth eruption-replacement and wear criteria under optimum laboratory conditions; and by (3) cementum-annulation counts. Incisors collected for cementum-annulation counts were decalcified in 5 percent nitric acid, sections 16-18 microns were cut on a cryostat and stained in hematoxylin for 18 ± 2 minutes. Age determinations by cementum-annulation counts showed 87 percent agreement with the results obtained by eruption-replacement and wear criteria in the laboratory.
Survival rates were estimated from the age distribution of 740 teeth aged …
