Abstract

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, C A L 5  mm and B L > 6  mm without reaching the tooth apex; group 3, C A L 5  mm and B L > 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 1 2 . 1 ± 2 . 8  mm in group 3, while for BL it was 4 . 8 ± 0 . 9  mm, 7 . 6 ± 2 . 2  mm, and 1 1 . 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.
