Hello Gopala, You may check out this link for detailed info on NEET cutoffs and colleges in tamil nadu: https://medicine.careers360.com/articles/neet-cutoff-tamil-nadu

With your marks its impossible to get into a govt dental college, you may however try for the following private dental colleges:

• Adhiraparashakti dental college and hospital
• Asan Memorial dental college and hospital
• Best dental college, madurai
• JKK Natrajah dental college and hospital
• Priyadarshini dental college and hospital

Hiii gopal...No, not at all, because at this score you aren't even fulfilling the qualification criteria of govt colleges. So there's hardly any chance of getting admission in any quota. 

sorry for being rude keep your gears on and prove me wrong the next year
