Hello punith,

Well speaking about the extra fields other than the MBBS or BDS are lot more but those are really considerd very less in the society. Frankly speaking people who have chosen bipc have more chances than the mpc people. I have suggested a few courses other than MBBS or BDS which you can prefer.
1. Bio technology
2. Bsc forensic
3. Bsc mlt
4. Bsc agriculture
5. Bsc animation
6. Bsc applied chemistry
7. Bsc applied science
8. Bsc bio informatics
9. Bsc biological science
10. Bsc food science
And lot more. These are only few options but you can surf through a lot more opportunities.

I hope this helps you.

Regards
