Hi, 

Since you havent mentioned any category we shall answer to your query assuming UR. 

Well with this score its difficult to get a seat in government dental college both under 15% AIQ as well as 85% state quota.

Last year the lowest closing score was of Government Dental College, Alappuzha-481.

So as per this trend your chances are bleak. But since this analysis is based on last years cutoff it may change since this trend vary every year. 

Regarding other options available to you;

You can opt for private colleges or deemed university. You will have a better scope there. 

I shall attach a link below for further help:
