RESUMO
Neurofibroma (NF) is a rare benign non-odontogenic tumor of the oral cavity. NF may present either as solitary lesions or as part of the generalized syndrome of NF or von Recklinghausen’s disease of the skin. The heterogeneous nature of NF was established by Riccardi et al. and he recognized at least seven types of NF. Among these proposed classifications of the disease, two distinct forms are generally accepted namely, a peripheral form known as NF Type I (NF-I), and a central form known as NF-II. NF-I represents the classic form of this disease, described by Recklinghawsen in 1882. Clinically, oral NF usually appears as slow growing, painless, pedunculated or sessile nodules. For illustration, a case of a NF with oral findings is been presented.

The mouth is a unique site, due to the presence of hard and soft tissues in close approximation. It serves in various purposes of speech, mastication and digestion. It is an important entry point for many pathogens in the body. Many systemic diseases manifest in the oral cavity and mouth can show early signs or the only signs of a disease process at a site elsewhere. As the mouth is an easily accessible site, the indicators it shows of various diseases should not be overlooked. A dentist thus can frequently be exposed to such conditions and play a key role in the diagnostic procedure of various systemic diseases. Appropriate knowledge of these oral manifestations is essential for early diagnosis, treatment and referral of cases.

La monografía "Alteraciones Gingivo-Periodontales en niños y adolescentes", es resultado de la recopilación y análisis del material bibliográfico que en las últimas décadas se ha producido en relación al problema en los países anglosajones y habla hispana. La información recolectada se sistematiza partiendo de consideraciones generales en relación al tejido gingivo-periodontal sano para abordar así, el estudio de sus alteraciones en la niñez y adolescencia; enfatizando el papel de la placa bacteriana como factor etiológico fundamental o ligado a condicines sistémicas genéticas o adquiridas que debilitan la capacidad de resistencia del individuo y hacen vulnerable el tejido gingivo-periodontal a la acción destructiva de la microflora existente en la cavidad bucal. Estas alteraciones se engloban en el estudio bajo la denominación "cambios gingivo-periodontales por factores locales y predisponentes específicos", destacandose la etiología, evolución, patogenia e histología de la gingivitis, periodontitis y otras manifestacions periodontales asociadas con infecciones y alteraciones sanguíneas del sistema eritrocitario plaquetario y leucocitario. Por último, se hace referencia a los cambios gingivo-periodontales en pacientes con hábitos bucales y alteracioes físicas, mentales y de comunicación
