LEONARDI, Denise Piotto et al. Pulp and periapical pathologies. RSBO (Online) [online]. 2011, vol.8, n.4, pp. 47-61. ISSN 1984-5685.

The pulp undergoes inflammatory or degenerative reactions when submitted to an aggressive factor. These depend on the type, frequency and intensity of the irritant as well as the patient's immune response. If the aggressive agent is not removed, the pulp will either show calcifications or result in necrosis. This latter would occur when a pulp alteration is present and not treated. Pulp necrosis is the complete cessation of the tissue's metabolic processes. If it is not removed, the bacterial and the tissue decomposition's toxic products will injure the periapical tissues, resulting in periapical alterations. The dentist must know the histological, clinical and radiographic features of these pathologies to recognize them and indicate the best treatment option.
