Erupted Complex Odontoma Mimicking a Mandibular Second Molar
Complex odontoma (CO) is considered one of the most common odontogenic lesions, composed by a miscellaneous of dental tissue such as enamel, dentin, pulp and sometimes cementum. They may interfere with the eruption of an associated tooth, being more prevalent in the posterior mandible. CO has been rarely reported as erupted, being considered an intraosseous lesion. This is a case report of a 17-year-old male with a benign fibro-osseous lesion consistent with CO that was located at the left second molar region, above the crown of the impacted mandibular second molar tooth. The lesion was surgically removed, and the tooth had to be extracted, since there was no indication that it could erupt naturally or with orthodontic traction. The histopathological examination confirmed the diagnosis of CO and after 6 months complete bone formation was observed radiographically. An early diagnosis will provide a better treatment option, avoiding tooth extraction or a more damaging surgery
Plurality Voting: the statistical laws of democracy in Brazil
We explore the statistical laws behind the plurality voting system by
investigating the election results for mayor held in Brazil in 2004. Our
analysis indicate that the vote partition among mayor candidates of the same
city tends to be "polarized" between two candidates, a phenomenon that can be
closely described by means of a simple fragmentation model. Complex concepts
like "government continuity" and "useful vote" can be identified and even
statistically quantified through our approach.Comment: 4 pages, 4 figure
