Representative images of histological analysis of the periapical region after 30 days of pulp exposure. Group C (A, a1, a2) presented a moderate to intense inflammatory infiltrate, in addition to an extensive area of periapical bone resorption; group PE (B, b1, b2) exhibited a mild to moderate inflammatory infiltrate and a smaller area of bone resorption. The PEO group (C, c1, c2) exhibited a mild inflammatory infiltrate and a small area of apical bone resorption. ab, alveolar bone; ce, cementum; pn, pulp necrosis; (hematoxylin-eosin stain, original magnification Ă—100 and Ă—400).
