No.
Explanation:
The bristles should be soft as they brush your teeth. So they should be made of thermoplastics whereas the handle is just used for holding. So it should be made from thermosetting plastics.

Answer:
No the handle and bristles are not of same material because the if bristles are made of plastic or the handle of toothbrush is made of bristles or vice versa then it will hurt of teeth.
This is because the bristles are not made of cross linked chains, as it bents according to our teeths.
But in case of handle the material is made of crossed linked chain which is less flexible than the bristles.
