Whenever we are at a conference or at a lecture related to our major fields, pleasures and disappointments occur to us at the same time. Pleasures we feel originate from finding lecturers sharing similar principles with us, which is reassuring, encouraging us to abide by our professional philosophy. However, there are also some lecturers who let us down.
Knowledge is dynamic and theories are always controversial, never stagnant. Maybe the verity of the present will be proven to be illusion in the future.
Back to our point, we believe in evidence-based dentistry and that lectures should be prepared based on the scientific data. In order to add evidence to one's lectures, results of the study and treatment should be organized into data.
As scientists who are also clinicians, we should approach research work and clinical therapy with an objective attitude, bearing in mind that there are two sides to every theory. In particular, we hope the reader realizes the pros and cons of each situation. We already knew that the patients in the hospital might improve faster with more family contact, but family in the intensive care unit could contaminate the space and cause fatal infections.
Looking for the truth is indeed full of challenges. At this moment, we should recall Johann Wolfgang Von Goethe's words: "Everything has been thought of before, but the problem is to think of it again." Taking this as our goal, we can be courageous with a fair and impartial attitude on all scientific matters.
