Oh I'm aware of the literature on rodent dentition, indeed, several of the papers I presented over at RDF covered this topic, including the not so insignificant matter of changing the tooth fate of the relevant rodent cells by modifying bmp4 and fgf8 signalling. However, work on human teeth is still a little way behind, because researchers want to be sure that they've learned everything they need to learn from the animal models first, before moving on to human teeth in a big way.
