I am indeed happy to be amidst this august gathering of distinguished dental professionals from over 138 countries, dental industry leaders, academicians and research scholars. At the outset, I would like to compliment the FDI World Dental Federation and Indian Dental Association for hosting this prestigious Annual World Dental Congress in India with the theme "a billion smiles welcome the world of dentistry. Smile is a universal language, and I am glad to see that you all, who play a vital role in bringing real smiles on the face of billions of people, have come together to deliberate on the critical and emerging issues in the field of oral healthcare and dentistry.
