As a part of the awareness campaign, Om Samaj Dental Hospital in partnership with Dental Association conducted an awareness raising event and felicitated different personalities for their contribution. On the occasion, Minister for Education, Science and Technology Krishna Gopal Shrestha called for public awareness on oral health and cautioned not to take lightly this issue.
