[ 1] That is, the number, type, and morpho-physiology (that is, the relationship between the shape and form of the tooth in question and its inferred ...
For human teeth to have a healthy oral environment, all parts of the tooth must develop during appropriate stages of fetal development. Primary (baby) teeth start to form between the sixth and eighth week of prenatal development, and permanent teeth begin to form in the twentieth week. [ 1] If teeth do not start to develop at or near these ...
