Abstract

Tooth development is essentially studied in mice, the favorite mammalian model in biology. However, mice do not replace their teeth on contrary to numerous mammals. So, the mechanisms involved in mammalian tooth replacement are still unknown. In this thesis, we focused on mammalian dental development and replacement using the European rabbit Oryctolagus cuniculus as animal model. The European rabbit is already sequenced, used in biomedical field, has a short gestation time and replaced its teeth, so rabbit seemed to be a relevant model in dental research.Rabbit dental development was not defined, so we first performed a histo-morphological study to characterize the development of deciduous and permanent teeth. 3D soft tissue reconstructions...
