Hi Priyanka 

Stipend varies from college to college unfortunately. Also depending upon whether its a GDC/ private college/ own university. And which city/ town you're located in.

The stipend varies but generally it is in following form for UG :

•  1st Year : 30000
•  2nd Year  : 35000
•  3rd Year : 40000

Post graduate students are paid stipend only in government dental college, bangalore as far as my knowledge goes. It may must around 25k/month.

Hope this helps you.

Good Luck.
