Hello aspirant,

As per last year cutoff Tamil Nadu Government Dental College & Hospital, Chennai college was alloted with marks 529 and rank 12283 with BC category under 85% state quota seats so it seems difficult for you to get the Government dental college woth your secured marks. You may apply for private dental college. As cutoff changes every year it is difficult to tell you the exact.

Best of luck!!
