P-45 Differences in Enamel Microstructure of Ictidomys Tridecemlineatus Formed during Hibernation Versus the Active Season

Description

The incisors of a ground squirrel grow continually throughout their life, making them a record of their most recent weeks of life. Previous research demonstrated that an abnormality in the incisor enamel and dentin of thirteen-lined ground squirrels (Ictidomys tridecemlineatus) corresponded with hibernation. Using scanning electron microscopy, we will determine whether the external disruption in incisor enamel is reflected in internal enamel microstructure by comparing the microstructure of normal enamel versus hibernation enamel. Our results may give insights as to why and how enamel disruption occurs during hibernation rather than the active season.
