O objetivo deste trabalho é resgatar um pouco da rica história do estudo da cicloide. Para isso, ser˜ao mostrados inicialmente os passos da sua construção, as deduç˜oes de suas equaç˜oes polares e cartesianas que, a seguir, ser˜ao utilizadas nos cálculos da área sob um arco dessa curva, da reta tangente, bem como, do comprimento desse arco. Ser˜ao reconstituídas etapas das aplicações da cicloide nos casos do pêndulo de Huygens, em que ela se comporta como isócrona (mesmo tempo) e do problema da braquistócrona (tempo mínimo) que desafiaram os grandes matemáticos dos séculos XVII e XVIII, com destaque para Huygens e os irm˜aos Jakob e Johann Bernoulli.

The non-eruption of teeth due to highly keratinized gingival mucosa is a frequent event in the pediatric dentistry, which harms the oral aesthetics and function. A surgical excision of the involved area is indicated, exposing the non-erupted tooth. This procedure involves anesthesia and cutting instruments that may increase the fear and anxiety in young patients. The use of new technologies has avoided these instruments and has promoted more comfort to the patients. This study presents clinical cases in which gingivectomy was performed using the innovative method with an ultrasound-activated CVD tip. It was concluded that this method presented effectiveness, promoted more comfort, and less fear to the patients, making its use a viable alternative to pediatric surgery.

It should be noted that the studies for some time been considering the historical importance of objects and space as components of memory - or “places of memory” in the words of Pierre Nora. The memory would thus be defi ned as an imaginary dimension of society, a mental universe that acquires and social substance that creates the individual with a “social whole” in an open line of work by M. Halbwachs. And this notion of memory allows us to grasp the question sheet. This cult of memory had its place also rise through the delimitation of national heritage - as Françoise Choay, since the establishment of categories of historical monuments in France in 1837. The discussion on equity has progressed in recent decades, as it is conceived as objects, spaces, knowledge and events become “intangible heritage” because it has reference value to the community. It is considered that the references are the property constituting the objects of memory formation, forms of work-life past or present. Anyway, heritage presents itself as the embodiment of a discourse about the past.

The starting point of this paper is a brief report of a specific research about a Brazilian institution called Grupo Escolar. Its main intention, however, lies in the discussion on some methodological procedures and some distinct scientific practices in Human Sciences. Authors make some remarks on the possibilities of alternative research protocols, its boundaries and potentialities, specially focusing the study of school archives and the use of Oral History approach. The discussion about Oral History brings to the scene two others important themes – childhood and elderliness.
