Dentistry is both an art and a science. It is a science because our fundamental understandings - or building blocks of knowledge, are based on the scientific process of research. This includes basic, applied, and clinical research. It is an art where it is based on experience and personal observation. The synthesis of scientific understanding (evidence) and clinical observation (evidence) provides the basis for meaningful dental care. Evidence based approach is ideal in today's situation and we doctors should be well versed with this approach and use evidence wisely in clinical decision making.
