Dentin appositional rates were determined in pregnant and lactating rats and compared with those in non-pregnant, age-matched controls. Appositional rates were calculated from measurements of distance between fluorescent mineralized tissue markers. There were significant increases in dentin apposition during pregnancy, with the greatest increases seen in the first two weeks. Dentin appositional rates decreased significantly during mid-lactation. These results indicate that homeostatic changes during pregnancy and lactation affect mineralized tissue accretion.
