ABSTRACT
O limite apical de trabalho sempre constituiu um tema de muita controvérsia. Apesar dos vários trabalhos que já foram publicados sobre o assunto, ainda não existe uma definição sobre ele. A recente discussão sobre patência apical e limpeza do forame e a incorporação desses procedimentos ao tratamento endodôntico parece ter gerado uma polêmica maior ainda. É possível que essa polêmica tenha a sua causa maior na ausência de interrelação do conhecimento que se tem sobre o coto pulpar e tecidos periapicais e a realidade dos fatos da clínica. Através de uma discussão sobre os principais aspectos desse tema, este artigo pretende apresentar uma nova concepção a respeito da importância da patência apical e limpeza do forame no preparo do canal.

Members of Bacteroidaceae family are the most commonly isolated anaerobic pathogens in humans. This study summarises our experience of isolation and antimicrobial susceptibility pattern of these anaerobes from diverse clinical infections in a tertiary care hospital. Over a period of 5 years, 611 samples were received for anaerobic culture. Of these, 53 specimens yielded 62 anaerobic isolates. Thirty of the 62 isolates (48.4%) belonged to Bacteroidacea family obtained from 29 patients. They comprised of 14 (14/32; 43.7%) Prevotella spp., 13 (13/32; 40.6%) Bacteroides spp., 3 (3/32; 9.3%) Porphyromonas spp and Fusobacterium (2/32; 6.2%). In 14 of 27 patients (48%) the infection was polymicrobial. All the isolated strains were sensitive to metronidazole. This study highlights need for adopting anaerobic culture technique as a routine diagnostic procedure and constant monitoring of antimicrobial susceptibility of all anaerobic isolates.

Blood for culturing was taken from suspected cases of infective endocarditis. 26 such patients were studied as regards the predisposing factors. 3 blood cultures were taken from each patient. Out of these 26 patients 4 gave history of dental manipulation, as the causative predisposing factor which gives a percentage of 15. 38%. These four patients were all seen to be infected by streptococcus viridans
