The Orthodontics – and wherever it goes – may be considered the synthesis of the current Brazilian Dentistry for presenting a significant scientific and technological advancement, always following the worldwide trend, and seeking for the worldwide recognition. Besides, like the Brazilians' oral health, the Orthodontics start to be considered and revendicated within the public health sector so its benefits become democratized. Concepts such as interdisciplinarity and promotion of health are increasingly more associated to Orthodontics, integrating it to other specialties and as an important part of general health of the body, besides being seen through the bias of prevention and basic care.

Kurt Faltin, Leopoldino Capelozza Filho, Emanuel Dias de Oliveira e Silva, José Augusto Mendes Miguel, Maria Helena Miotto, Ronaldo da Veiga Jardim, Ricardo Lombardi and Stenyo Wanderley Tavares – talk about all these Orthodontics' faces and interfaces.
