Periodontal therapy can be broadly classified as surgical and non surgical therapy. Non surgical therapy includes: patient's motivation, plaque control, supra and subgigival acaling, root planning and complementary use of chemical agents. Non surgical therapy is an effective method of periodontal therapy. Longitudinal studies have found that non surgical therapy was effective for single rooted teeth, and multi rooted teeth and also, in shallow deep pockets. It must be pointed out that non surgical therapy may not be effective in some sites and even in some patients, therefore in must be recognized that after reevaluation appointments it should be performed an appropriate surgical therapy.

Necrotizing periodontal Diseases and Conditions in 1999 are two: Necrotizing gingivitis (NG) and Necrotizing periodontitis (NP). Necrotizing stomatitis (NE) is a more aggressive variation, which can be linked to the two entities mentioned. In this review we discuss their definitions, etiology, clinical aspects, diagnosis and treatment, trying to clarify these points with updated concepts.

Las enfermedades periodontales necrotizantes según el Taller Internacional para la Clasificación de la Enfermedades y Condiciones Periodontales realizado en 1999, son dos; la Gingivitis Necrotizante (GN) y la Periodontitis Necrotizante (PN). Una variación más agresiva, que puede estar ligada a las dos entidades mencionadas es la Estomatitis Necrotizante (EN). En esta revisión trataremos sus definiciones, etiología, aspectos clínicos, diagnóstico y tratamiento, tratando de aclarar estos puntos con conceptos actualizados.

This article presents a review of the most important aspects from necrotizing periodontal disease, specia-lly about clinical features, diagnostics, etiology, evolution, prognose and treatment.

Objective: Determine the presence of black pigmented bacteria (BNP) in periodontal pockets before and after periodontal treatment. Materials and method: The type of study is descriptive which has a sample of 10 areas, ten patients in which periodontal pockets were identified, samples were taken with paper cones, which were then cultured in blood agar medium with hemin and vitamin K, incubated. Subsequently he identified and counted the black pigmented colonies before and after periodontal treatment. Results: Of the first samples examined before treatment could be recovered BNP 60 % of cultured samples with a range of presence of 16-312 CFU and samples obtained after periodontal treat-ment could be recovered in 50 % of them , with a range of 5 to 70 presence UFC, and this is confirmed by statistical analysis. Conclusions: It is concluded that BNP is present in periodontal pockets and that...

Objetivo: Determinar la presencia de bacterias negro pigmentadas (BNP) en bolsas periodontales, antes y después de un tratamiento periodontal. Materiales y método: El tipo de estudio es descriptivo. Tiene una muestra de 10 áreas, de 10 pacientes, en la que se identificaron bolsas periodontales. Se tomaron muestras en conos de papel, que luego fueron cultivados en el medio de agar sangre con hemina y vitamina K, incubados. Posteriormente se identificó y contabilizó las co-lonias negro pigmentadas, antes y después del tratamiento periodontal. Resultados: De las muestras examinadas antes del tratamiento, se pudo recuperar BNP en un 60 % de muestras cultivadas, con un rango de presencia de 16 a 312 UFC. De las muestras obtenidas después del tratamiento periodontal, se pudo recuperar en un 50 % de ellas, con un rango de presencia de 5 a 70 UFC. El análisis estadístico demuestra la di...
