    Purpose. To evaluate the histopathological condition of the pulp in teeth with different levels of chronic periodontitis in humans. Methods. Twenty-five single-root nondecayed teeth were divided into three groups as follows: group 1, clinical attachment level (CAL) 3 to 4 mm and alveolar bone loss (BL) from 4 to 6 mm without reaching the tooth apex; group 2, CAL ≥ 5 mm and BL > 6 mm without reaching the tooth apex; group 3, CAL ≥ 5 mm and BL > 6 mm up to the tooth apex. Histological analyses were accomplished after laboratorial processing. Results. The mean of CAL was 3.2 ± 0.7 mm in group 1, 7.6 ± 2.0 mm in group 2, and 12.1 ± 2.8 mm in group 3, while for BL it was 4.8 ± 0.9 mm, 7.6 ± 2.2 mm, and 11.9 ± 2.1 mm, respectively. Histopathological data in the pulpal chambers were similar among the three groups showing normal aspects, and, the radicular pulps showed variable levels of reactive dentin, fibrosis, dystrophic mineralizations, atrophy, and mononuclear inflammatory infiltrate. Conclusions. Gradual progression of the chronic periodontitis led to changes in the histopathological aspects of the radicular pulp with progressive involvement

    La Periodontitis es una enfermedad inflamatoria crónica que está relacionada con algunas alteraciones sistémicas. La gravedad de la inflamación de los tejidos periodontales ha sido asociada a una inflamación sistémica considerada de bajo grado y, algunos estudios han sugerido que hay un aumento en los niveles de proteína C-reactiva y en el número de leucocitos de la sangre en pacientes periodontalmente comprometidos. Las células de la serie roja de la sangre también podrían verse afectadas por la presencia de periodontitis, influyendo asi en la aparición de anemias. A pesar de eso, aún hay controversias en hasta qué punto las enfermedades periodontales podrían influenciar de forma directa en la aparición de las inflamaciones sistémicas. De esa forma, el objetivo de este trabajo fue realizar una revisión de literatura para verificar la posible influencia de la enfermedad periodontal sobre las células sanguíneas y los niveles de proteína C-reactiva. ABSTRACT Periodontitis is a chronic inflammatory disease that is related with some systemic alterations. The severity of the inflammation in the periodontal tissues has been associated with a low-grade measurable systemic inflammation, and some studies have suggested an increase in the C-reactive protein levels and in number of white blood cells in patients with periodontal diseases. The red blood cells also could be affected by periodontitis with trends toward anemia. There are still controversies in relation to the direct influence of periodontal diseases in the occurrence of systemic inflammations. Thus, the aim of this study was to accomplish a literature review in order to verify the possible influence of the periodontal disease on blood cells and C-reactive protein levels
