In 2019, under State Quota, 396 marks secured a seat in Rajah Mutiah Dental College under OBC Category. That was the cut off. Now this is 2019 data and cut offs change every year. Cut offs change every year depending on various factors such as no.of Candidates appearing for the exam, no.of Candidates qualified, top NEET score and difficulty of the exam. For a seat in Government Dental College under OBC Category, you will need atleast 450-475 for this year. This is because there are only 2 Government Dental Colleges in Tamilnadu and hence the competition is tough. When the available seats are less, the cut offs increase.
