Hello there. 

In 2017, the last candidate to get admission in BDS at MAIDS i.e. Maulana Azad Institute of Dental Sciences was 16219 with the marks ranging between 530-535.

In 2018 the marks must have been inflated around 545.

So, as you in are in Class XI right now, for NEET 2020 try keeping a target around 560 to stand chances of getting into MAIDS.

The above figures for 2020 are only a result of prediction and may vary depending upon the difficulty level of paper, number f candidates writing the examination etc.

Hope this helps.

All the best.
