 Kindly clarify. My textbook (ICSE Concise Biology) reads that in the set of milk teeth the molars are missing and the dental formula is 2,1,2,0. Whereas in these notes it has been written that the premolars are mising and the dental formula is 2,1,0,2.

Dear Student,

The milk teeth lack molars and the dental formula is 2120/2120 as given in your book.

We appreciate your bringing the error to our notice. The said topic  will be corrected and updated very soon. We shall most definitely try and ensure that such errors do not occur in the future. We regret the inconvenience caused by this lapse on our part. Your feedback and suggestions are extremely valuable to us.

It should also be stated that in deciduous teeth, they are the molars which grow in the place of premolars thus being named as premolars. So actually till the age of 7-8 years the molars occupy the space of premolars which is then occupied by the new set of teeth which are actually the premolars and the molars start to grow behind them.
