Dens evaginatus is a disturbance in tooth formation that appears clinically as an accessory occlusal tuberculated cusp composed of enamel and dentin, usually enclosing pulp tissue. The tubercle often fractures or is worn away, with subsequent pulp exposure leading to pulpal inflammation, necrosis, and periapical inflammation. When this happens to an immature tooth, diagnosis may be complicated ...

This case report presents the periapical surgical retreatment of an Oehlers Class III invaginated maxillary central incisor with extruded root canal filling into the periapical lesion. After local anesthesia, a full-thickness mucoperiosteal flap was reflected, and the granulomatous tissue and extruded gutta-percha points were curetted carefully. A deep and wide root-end cavity was prepared and ...

Most of periapical lesions usually result from microbial infection with oral microorganisms originating the degenerated pulp tissue. These are commonly painless and incidentally found on routine radiographic examinations. Treating these cases using non-surgical root canal is fruit innovative techniques, tools medicaments as well tendency toward minimally invasive treatment. The healing process ...

The aim of this study was the histopathological evaluation of apical and periapical tissues in dog teeth that were submitted to bacterial endotoxin, associated or not with calcium hydroxide. After removal of the pulp from 60 premolars, the teeth were divided into four groups and were filled with bacterial endotoxin (group 1), bacterial endotoxin plus calcium hydroxide (group 2), saline solution...
