The knowledge that light is beneficial and may lead to cure does not belong exclusively to our time; Greek and Ancient Egyptian doctors practiced cures by exposure to sunlight. However, it was in the past century that one of the great technological advancements was made: the development of laser appliances for use in fields ranging from CDs and DVDs to performing surgeries and treating diseases. Taking into consideration the scope and importance of the subject, coordinating this book, in which renowned researchers and clinicians who work with lasers in dentistry have participated, has certainly been a great responsibility. With love, belief in our ideals, and enthusiasm, we accepted the challenge. At this time, in seeking knowledge and intellectual preparation to deal with the different situations in which life places us, our major ally has certainly been God. With Him, challenges have been overcome and limits transformed into actions to bring our readers all the latest information concerning the use of lasers and LEDs in dentistry.
There is no longer any doubt that therapies with lasers and LEDs have positive results; nevertheless, there is still no consensus about the best manner of application of these therapies in each clinical situation for optimal results. The incessant search for effective clinical protocols was the starting point for this extensive work, with the aim of opening the clinical professional’s eyes to the various possibilities for the use of this new technology in dentistry. These protocols are not immutable, but they are supported by basic and clinical research. These are protocols that open various doors to other new protocols and clinical applications of lasers and LEDs in the diverse specialties of dentistry. They are protocols designed to enable you to explore this world, in which light interacts with soft and hard oral tissues, bringing benefits to our patients. Explore, question, innovate… We challenge you, the reader, to become part of this work, to make use of the broad body of knowledge that has so honorably been shared with us by our collaborators!
