Abstract
Objective To study the tooth germ development of mouse molar in fluorosis. Methods We established an acute fluorosis model and used HE-staining after preparing specimens of different stage of mouse first molar developing tooth germ. Results The developing molars of the control fetuses were at the bell stage of odontogenesis, whereas those of the experimental population were at cap stage. The ameloblasts became shorter and lost polarity. The arrangement of ameloblasts fell into disorder at the bell of differeiational stage and secretory stage. Conclusion The developing molars of the experimental fetuses were retarded. High-dose fluoride has a strong effect in the ameloblasts at the bell of differetiational stage and secretory stage.
