Resumen
Objetivos

Evaluar la composición microbiológica y los parámetros clínicos de bolsas periodontales ≥5mm de profundidad al inicio, 1 semana, 3 y 12 meses post raspado y alisado radicular.

Materiales y Métodos

Se tomaron registros clínicos y muestras de placa subgingival de 44 sitios de pacientes con diagnóstico de periodontitis crónica. Se identificaron por técnica de Reacción en Cadena de la Polimerasa (PCR) patógenos putativos periodontales: Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Treponema denticola (Td), Tannerella forsythia (Tf) y Prevotella intermedia (Pi). Los pacientes recibieron terapia mecánica periodontal y fueron reevaluados a los 7 días, 3 y 12 meses.

Resultados

Luego del tratamiento, todos los parámetros clínicos (Placa Bacteriana, Hemorragia, Supuración, Profundidad al Sondaje y Nivel de Inserción Clínica) se redujeron significativamente y los valores obtenidos se mantuvieron hasta los 12 meses. Al inicio, las especies bacterianas prevalentes fueron Pg, presente en 66% de los sitios, Tf (55%) y Td (41%). Los sitios más profundos se relacionaron con las asociaciones Tf-Td (6.8mm) y Tf-Td-Pi (7mm). Post terapia, el número de sitios positivos para Td, Tf y Pg se redujo significativamente.

Conclusiones

El raspado y alisado radicular mejoró significativamente los parámetros clínicos y redujo la prevalencia de los patógenos periodontales Pg, Tf y Td en bolsas periodontales profundas. Los resultados obtenidos se mantuvieron hasta los 12 meses. No se detectaron mayores pérdidas de inserción clínica en el 86% de los sitios a 3 meses y en 79% a los 12 meses. Los sitios en los que el tratamiento no fue efectivo en la eliminación de patógenos a los 12 meses desarrollaron mayores profundidades de sondaje.

Abstract
Objectives

To evaluate the microbial composition and clinical parameters of periodontal pockets with probing depth ≥5mm at baseline, 1 week, 3 and 12 months after scaling and root planning.

Methods

Clinical parameters were measured and bacterial samples were collected from 44 sites in 11 patients with chronic periodontitis. By means of Polymerase Chain Reaction (PCR) the presence of Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Treponema denticola (Td), Tannerella forsythia (Tf) and Prevotella intermedia (Pi) was estimated. The patients received mechanical periodontal therapy and were evaluated after 1 week, 3 months and 12 months.

Results

After treatment, all clinical parameters (Plaque, Bleeding on Probing, Supuration, Probing Pocket Depth and Clinical Attachment Level) were significantly reduced, and the values obtained were maintained up to the 12 months that the study lasts. At baseline, the most prevalent species were Pg, present in 66% of the sites, Tf (55%) and Td (41%). The deepest sites were related to the association Tf-Td (6.8mm) and Tf-Td-Pi (7mm). The number of positive sites for Td, Tf and Pg was significantly reduced after therapy.

Conclusions

Scaling and root planning improve significantly clinical parameters as well as reduce the prevalence of periodontal pathogens Pg, Td and Tf in deep periodontal pockets. The results obtained were maintained up to 12 months. No further clinical attachment loss was found in 86% of the sites at 3 months and 79% at 12 months. The sites where the treatment failed in removing pathogens developed at 12 months greater probing pocket depths.
