Hey aspirant,

As you haven't mentioned your category to which you belong so considering you to be from a general category, I guess you can get government BDS colleges based on your marks. As far as I have researched on the cutoffs of colleges, scoring 430+ marks can give you seat in some of the government BDS colleges. But since you haven't mentioned your homesate so I'm not able to suggest you dental colleges.

On the basis of All india quota you won't get government dental colleges. For that you must have score 500+ marks.

On the basis of home state quota 85% you may get seats in some of the government dental colleges. For that please visit the link mentioned below-

Hope it helps.

Good luck.
