Which of the following terms describe human dentition?

  1. Pleurodont, Monophyodont, Homodont
  2. Thecodont, Diphyodont, Homodont
  3. Pleurodont, Diphyodont, Heterodont
  4. Thecodont, Diphyodont, Heterodont

Answer

(4) Thecodont, Diphyodont, Heterodont

Solution

As per NCERT:

Each tooth is embedded in a socket of the jaw bone ⇒ thecodont.

Humans form two sets of teeth (milk or deciduous teeth and permanent teeth) ⇒ diphyodont.

An adult human has 32 permanent teeth of four different types (incisors, canine, premolars and molars) ⇒ heterodont.

∴ Human dentition is thecodont, diphyodont and heterodont.
