Hii !!
The chances of getting into government medical colleges is very rare for your marks. There is only one government dental college with cut off 256 - ESIC Dental College, Gulbarga.
Anyway you can try private colleges through minimum cut off or payment seat. The payment seat will be of minimum morethan 3 lakhs for any medical college.
I have shared a link below which tells you the list of colleges and its cutoff. Click on the link and download the PDFs and check on the cut off for your category.
