Dentition whether or not it has erupted. Regarding premolars, there is disagreement regarding whether the third type of deciduous tooth is a premolar (the general consensus among mammalogists) or a molar (commonly held among human anatomists). There is thus some discrepancy between nomenclature in zoology and in dentistry. This is because the terms of human dentistry, which have generally prevailed over time, have not included mammalian dental evolutionary theory. There were originally four premolars in each quadrant of early mammalian jaws. However, all living primates have lost at least the first premolar. "Hence most of the prosimians and platyrrhines have three
Moyer's mixed dentition analysis mouth, and does not require any radiographic projections. Limitations of this analysis are that this is a probability analysis, does not account for tipping of incisors lingual or buccal and that maxillary tooth sizes are predicted by the mandibular tooth sizes. Other limitations of this analysis is that Moyer's never clarified which population this analysis was done on initially. Therefore, this analysis cannot be truly applied to different populations. This was confirmed by a systematic review which was performed in 2004. Moyer's mixed dentition analysis Moyer's mixed dentition analysis was created in 1971 by Robert Moyers . This an analysis
