Hello Shanmuga,
KSR Institute of Dental Science is among the good colleges of state for dental science and yes, it's hostel will provide you a good environment to pursue your studies.
Im my opinion, it's upto you how a hostel life you choose. There are some students who waste their time by doing nothing in hostel and on the other side there are some students who study hard in hostel and secures good marks in examination.
Hope this helps.
Good luck!!!
