Regeneración ósea de un defecto circunferencial de tres paredes con hueso autólogo / Autologous bone regeneration of an circumferential three walls defect

La periodontitis provoca, a lo largo de su proceso evolutivo, un deterioro de los tejidos periodontales, entre ellos del hueso alveolar. En la mayoría de las ocasiones, la progresión de esta enfermedad puede ocasionar defectos óseos. Su tratamiento consistirá en la eliminación delos factores etiológicos y recuperar, en la medida de lo posible, la estructura perdida mediante diferentes técnicas regenerativas o respectivas. En el presente artículo, se muestra una opción para el tratamiento de un defecto óseo circunferencial de tres paredes, comparándolo con diferentes alternativas de tratamiento para combatir este defecto (AU)

The periodontal disease causes, along the evaluative process of the illness, a damage of periodontal tissues, including the alveolar bone; in many times, the evolution of the pathology makes irregular bone deformities. The treatment of that disease could be to eliminate the etiological factors and to recuperate as much as possible, the missed structure with regenerative and respective techniques. In this article, we will set up a clinical case where we will describe a treatment option of a circumferential bone defect and we will compare that treatment with others alternatives (AU)

Oral and perioral piercing complications.

BACKGROUND.: The oral an perioral piercing has a long history as part of religious, tribal,cultural or sexual symbolism and nowdays there is a high incidence of oral and perioral piercing in the adolescent population. This practice has a long history as part of religious, tribal, cultural or sexual symbolism. This article reviews current knowledge on injuries or diseases that might be produced by piercing in the oral cavity. We propose a classification to diagnosed the pathologies related to oral an perioral piercing METHODS.: A search was conducted of articles in PubMed, Scielo published between 1997 and 2007, using the key words ;;oral and perioral, piercing , ;;oral, piercing and disease", ;;recessions and oral piercing . It has reviewed about twentythree articles 17 were narrative reviews and 6 case series RESULTS.: A review was carried out on the origins of oral and perioral body piercing and its local implications, classifying the different alterations like recessions, systemic implications that it can produce in the oral and perioral cavity. CONCLUSION.: Patients with oral and perioral piercing should be regularly followed up because of the possible development of different types of adverse effects. CLINICAL IMPLICATIONS.: Adverse effects of oral and perioral piercing can be systemic, with transmission of infectious diseases such as hepatitis B or C, or can be local, with alteration of oral mucosae or even of dental structures.
