RESUMO
We investigated aspirates of pus from dentoalveolar abscesses in 13 patients who had received empirical antibiotic therapy within 1 month before presentation at our facility. The antibiotics administered were lincomycin, amoxicillin, ampicillin, or a cephalosporin. Information on antibiotic therapy was obtained from the patients' medical histories. Cultures of all dentoalveolar abscesses yielded organisms. A total of 70 isolates (42 anaerobes and 28 facultative organisms) were recovered, representing 5.3 isolates (3.2 anaerobes and 2.1 facultative organisms) per specimen. The counts of bacteria ranged from 5 X 10(7) cfu/mL to 8 X 10(11) cfu/mL (mean count, 1.4 X 10(11) cfu/mL; median count, 2.3 X 10(10) cfu/mL). The predominant isolates were Prevotella species (25.7% of isolates), Peptostreptococcus species (17.1%), and Streptococcus species (14.2%). This study illustrates the polymicrobial nature of dentoalveolar abscesses as well as the predominant role played by anaerobic bacteria.

An unusual case of regional odontodysplasia in an 8-year-old boy is presented. He was referred to our clinic because of failure of tooth eruption on the left side of the maxilla and frequent fever attacks. Treatment consisted of extraction of the affected teeth, and removal of inflamed tissue.

A case of paresthesia of the mental nerve following over-extension of root canal filling material into the inferior alveolar canal is presented. The causes of this complication are discussed and the importance of performing surgical treatment as early as possible is emphasized.

A tumor-like foreign body in the maxillary sinus is reported. Examination of the paranasal sinuses by computerized tomography revealed a dense and well defined lesion equal to that of bone in the left maxillary sinus. After surgery, the lesion was found to be alginate used for impression-taking before fitting of a prosthesis, and not a tumor.
