The Effect Of Tooth Shape On Crushing Load

We found that for all tooth shapes thicker shells are harder to break than the thinner shells and that increased ornamentation has no discernible effect Our results show that for both shell morphologies domed and flat teeth break shells better than cupped teeth and teeth
