Resumo: Abscessos apicais agudos são condições frequentes na urgência endodôntica. São infecções polimicrobianas que apresentam variações entre indivíduos, e afetam o sistema de canais radiculares e tecidos periapicais. Associações bacterianas podem ser importantes, agindo sinergicamente e aumentando sua virulência, o que agrava os danos causados no hospedeiro. Considerando a etiologia microbiana das alterações pulpares e periapicais, é de fundamental importância identificar corretamente as bactérias presentes nas infecções endodônticas. Métodos moleculares de identificação bacteriana, baseados no sequenciamento do gene 16S rRNA, são importantes e fornecem uma identificação mais fiel que métodos fenotípicos. Estudos metagenômicos são ideais para avaliação da diversidade bacteriana, possibilitando identificação de espécies que se acreditava não estarem sendo cultivadas, ou encontrar espécies que ainda não foram encontradas ou associadas com infecções endodônticas, incluindo espécies ainda não cultiváveis. O objetivo deste estudo foi investigar a diversidade bacteriana de canais radiculares de dentes com abscesso apical agudo por cultura, clonagem e sequenciamento do gene 16S rRNA, compararando a efetividade dos métodos. Foram feitas coletas microbiológicas de 20 canais radiculares utilizando cones de papel absorvente estéreis, transportados em meio VMGA III. Um total de 220 cepas isoladas, identificadas previamente por métodos bioquímicos, foram submetidas à extração de DNA, amplificação do gene 16S rRNA seguido de sequenciamento. Além disso, 10 das 20 amostras coletadas foram também submetidas à clonagem bacteriana através de Escherichia coli DH5? eletrocompetentes. As sequências de nucleotídeos obtidas foram comparadas com o banco de dados do National Center of Biotechnology Information através do BLAST. Trinta e quatro espécies diferentes foram identificadas bioquimicamente e 57 pelo sequenciamento, numa média de 6 espécies por canal. O sequenciamento permitiu identificação de 97% das bactérias isoladas (215), enquanto apenas 70,5% foram identificadas bioquimicamente (155). A concordância entre os métodos de identificação fenotípica e genotípica foi de 49% e as cepas não identificadas bioquimicamente (65/220) foram caracterizadas em 97% (63/65) pelo sequenciamento. As bactérias mais frequentemente identificadas pelo sequenciamento foram Prevotella spp., Pseudoramibacter alactolyticus, Parvimonas micra, Dialister invisus, Filifactor alocis e Peptostreptococcus stomatis. Um total de 689 clones foi analisado e 76 filotipos foram identificados, numa média de 15 por canal. Quarenta e oito espécies diferentes foram identificadas e 28 (36,84%) filotipos representados por espécies ainda não cultivadas ou não caracterizadas. Prevotella spp., Fusobacterium nucleatum, Filifactor alocis e Peptostreptococcus stomatis, foram às espécies mais frequentemente identificadas, seguidas por Dialister invisus, Parvimonas micra, Phocaeicola abscessus, Porphyromonas spp. e Lachnospiraceae oral clone. Nenhuma espécie foi encontrada em todos os casos estudados, e algumas estavam presentes em apenas 1 caso. Métodos que independem da cultura mostram que a microbiota endodôntica pode ser subestimada por estudos cultura-dependentes. Apesar de algumas espécies serem predominantes em infecções endodônticas primárias, como as anaeróbias Gram-negativas, concluímos que esta infecção é bastante complexa e heterogênea, caracterizada por uma grande diversidade bacteriana. A associação de métodos convencionais e moleculares permite um conhecimento mais acurado da microbiota endodôntica
Abstract: Acute apical abscesses are one of the most frequently treated conditions in endodontic emergency. It is a microbiologically heterogeneous disease presenting different bacterial profiles among the patients. Multiple bacterial combinations play a role in disease, acting synergistically and increasing their virulence, which leads to further damage to the host. Considering the microbial etiology of pulp and periapical disease, it is important to identify correctly microorganisms present in acute endodontic infection. Molecular methods of bacterial identification based on the 16S rRNA gene sequencing represent an important tool for identification and determination of the taxonomic position of microorganisms. The assessment of the endodontic microbiota by metagenomic approaches revealed that these techniques are sensitive and specific to evaluate the bacterial diversity of root canal infections, making possible the identification of some unexpected or not often associated with endodontic infection, including as-yet-uncultivated. The aim of this study was to investigate the bacterial diversity in the root canals of teeth with APA by culture, clonal analysis and 16S rRNA sequencing. Microbial samples were taken from 20 root canals using sterile paper points which were immediately placed into the VMGA III transport medium. A total of 220 isolated strains, previously identified by biochemical methods, were submitted to DNA extraction, 16S rRNA gene amplification and sequencing. Ten out of the 20 samples collected were also subjected to the clonal analysis using electrocompetent Escherichia coli DH5?. The nucleotides sequences obtained were compared with the GenBank database from National Center of Biotechnology Information through the BLAST. Thirty-four different bacteria were identified biochemically and 57 by 16S rRNA sequencing, in an average of 6 species per root canal. Sequencing allowed the identification of 97% of isolates against 70.5% identified biochemically. There was an agreement of 49% between the biochemical and 16S rRNA gene sequencing identification. Strains not identified biochemically (65/220) were characterized in 97% (63/65) by sequencing. The most frequently identified bacteria by sequencing were Prevotella spp., Pseudoramibacter alactolyticus, Parvimonas micra, Dialister invisus, Filifactor alocis and Peptostreptococcus stomatis. A total of 689 clones were analyzed and 76 phylotypes identified, of which 48 (63.15%) were different species and 28 (36.84%) were taxa reported as-yet-uncultivable or as yet-uncharacterized species. Prevotella spp., Fusobacterium nucleatum, Filifactor alocis and Peptostreptococcus stomatis, were the most frequently detected species, followed by Dialister invisus, Parvimonas micra, Phocaeicola abscessus, Porphyromonas spp. and the uncharacterized Lachnospiraceae oral clone. No specie was detected in all studied samples and some species were identified in only one case. Culture-independent methods shown that endodontic microbiota was underestimated in culture studies. Although some species predominate in acute primary endodontic infections, it was concluded that this infection is microbiologically heterogeneous, characterized by a wide diversity in which anaerobic gram-negatives are most frequently, and that the association of conventional and molecular approaches allow a better understanding of these microorganisms

Resumo: O aumento da longevidade humana faz com que estudos envolvendo indivíduos idosos tenham grande importância para os gestores e profissionais de serviços de saúde. O objetivo desse estudo foi avaliar a relação entre a qualidade das obturações dos canais radiculares e a presença de lesão apical em pacientes idosos. Os dados foram obtidos por meio de uma revisão sistemática de estudos que avaliaram a qualidade das obturações dos canais radiculares e sua relação com a saúde periapical. Os critérios de inclusão foram: a) estudos em humanos; b) amostra incluindo indivíduos com idade igual ou maior que 60 anos; c) definição de critérios claros e bem estabelecidos para a avaliação da qualidade das obturações endodônticas; d) definição de critérios claros e bem estabelecidos para a avaliação da saúde periapical; e) estabelecimento de relação entre a qualidade dos tratamentos endodônticos e a presença de lesões periapicais; f) artigos publicados em Inglês entre 01 janeiro de 1986 e 01 julho de 2013 nas bases de dados PubMed e ISI Web of Knowledge. A pesquisa produziu um total de 1.376 títulos de artigos potencialmente relevantes, dos quais 667 eram repetidos e 16 eram duplicados. Os resumos de 693 estudos foram lidos, sendo 608 destes excluídos e 85 selecionados para análise de texto completo. Catorze (14) artigos foram incluídos. Os resultados desta revisão mostraram que existem vários critérios para avaliação da qualidade das obturações dos canais radiculares e da saúde periapical, o que dificulta a comparação entre os estudos. Além dessas variáveis, as mudanças anatômicas causadas pelo envelhecimento, a presença de lesões no momento da obturação, o interstício de tempo para a avaliação do Peri ápice, o tipo de radiografia utilizada para avalição da qualidade das obturações e da saúde periapical e a falta de padronização na realização dos tratamentos endodônticos foram outros fatores identificados. A saúde do Peri ápice, representada pela frequência de periodontite apical, está intimamente relacionada à qualidade das obturações dos canais radiculares em pacientes idosos.
Abstract: The increase in human longevity causes that studies involving elderly individuals have great importance for managers and professionals of health services. The aim of this study was to evaluate the relationship between the quality of root canals (RC) and the presence of apical periodontitis in elderly patients. The data were obtained by a systematic review of studies that evaluated the quality of root canals and its relation with apical health. Inclusion criteria were: a) studies in humans; (b) sample including individuals with 60 years or older; (c) definition of clear criteria and well established for the evaluation of the quality of the root canals; (d) definition of clear criteria and well established for the evaluation of apical health; e) establishment of a relation between the quality of root canals and the presence of apical periodontitis; f) articles published in English from 1986 (January, 1st) to 2013 (July, 1st) in PubMed and ISI Web of Knowledge databases. The search produced a total of 1,376 potentially relevant titles of articles, of which 667 were repeated and 16 were duplicates. The summaries of 693 studies were read, being 608 of these excluded and 85 selected for analysis of full text. Fourteen articles were included. The results of this review showed that there were several criteria for assessing the quality of root canal obturations and the apical health, which makes the comparison between the studies. In addition to these variables, the anatomic changes caused by aging, the presence of lesions at the time of the closures, the interstice of time for the assessment of apical periodontitis, the type of radiography used for evaluation the quality of root canal obturations and apical periodontitis, and the lack of standardization of the endodontic treatments were other factors identified. The apical health, represented by the frequency of apical periodontitis, is intimately related to the quality of root canal obturations in elderly patients.

Full textThe present thesis aimed to analyze the antimicrobial resistance profile of bacteria isolated from acute endodontic infections through a systematic review and meta-analysis (Chapter 1); to identify and determine the genotypic diversity, antimicrobial susceptibility and virulence factors of isolated facultative anaerobes in isolates from acute apical abscess (Chapter 2); and to provide information for dentist and patients generated from guidelines on the use of antibiotic agents in acute endodontic infections (Chapter 3). The electronic databases and the gray literature were searched up to May 2015 for systematic review. PRISMA guidelines were followed. The clinical studies in of humans that have evaluated the antimicrobial resistance of the isolates of primary acute endodontic infections through laboratorial methods were included. A random effect meta-analysis was employed, and the outcome was described as being the pooled resistance rates for each antimicrobial agent. The data from 7 studies were extracted. The resistance rates for 15 different antimicrobial agents were evaluated, ranging from 3.5% to 40.0%. Lower resistance rates were observed for amoxicillin+clavulanate and amoxicillin, and higher resistant rates were detected for tetracycline. In Chapter 2, root canal samples were collected from seven teeth. Facultative anaerobic bacteria were identified by phenotypic methods and MALDI-TOF MS. Antimicrobial susceptibility of strains was determined to benzylpenicillin, erythromycin and clindamycin by disk-diffusion. Facultative anaerobic bacteria were isolated from 3 teeth. Streptococcus spp., Staphylococcus aureus, Enterococcus faecalis, and Actinomyces viscosus were found. Streptococcus spp. and S. aureus were susceptible to benzylpenicillin. E. faecalis strains (n=24) isolated from the same patients had their susceptibility determined by minimum inhibitory concentration of benzylpenicillin, amoxicillin and amoxicillin + clavulanate using the E-test. The genotypic diversity and virulence factors (ace, asa, gelE, efaA, cylA, esp) were analyzed in E. faecalis strains by PFGE and PCR, respectively. Phenotypic expression of gelatinase and cytolysin were tested. Biofilm production was quantified. All the E. faecalis strains were susceptible to β-lactam antibiotics. The same chromosomal DNA fragmentation profile was revealed to E. faecalis strains isolated. The gelE, ace and efaA genes were detected in 18 E. faecalis strains. Gelatinase expression and biofilm production were observed. E. faecalis strains had the same chromosomal DNA profile, but showed virulence profiles different. In Chapter 3, two sugestion for information texts were presented. The first aims to guide dentists on the proper use of systemic antibiotics in endodontics. The second aims to inform patients about the use of antibiotics and clarify possible doubts.

Full textPeriapical abscess and periapical granulomas are considered inflammatory lesions related to dental infections originated from pulpal and periodontal tissues. There is little information about the role of interleukin 17 (IL-17) on these lesions. IL-17 is a cytokine pertaining to a new class of immunological response termed Th17. Th17 response has been characterized by the IL-17 release by CD4+ lymphocytes and has been associated to stabilization and perpetuation of the inflammatory process, as well as to neutrophil recruitment. The present study focused on the investigation of the IL-17 expression in periapical abscess and periapical granuloma, in order to verify if there are differences between the lesions that could be related to level of neutrophil infiltrate. Immunohistochemical tests to IL-17, CD4 and CD8 (to identify different lymphocyte population) and elastase (to detect neutrophils) were performed in the periapical abscess (n=25) and granuloma (n=25) biopsies, selected from the collection of Surgical Pathology Service of the Department of Oral Pathology FOUSP. Percentage of the labeling area showing positive expression was obtained for the all cited markers. Counting of CD4+/IL17+ and CD8+/IL7+ cells detected by immunofluorescence was also performed. Friedman´s and Mann-Whitney non-parametric statistical tests were applied for the labeling area percentages in order to detect the significant differences between abscess and granuloma. Spearman´s correlation test was adopted to verify whether there was a correlation between IL-17 and the other markers. In the periapical abscess biopsies, elastase, IL-17, and CD8 were intensively labeled, with area percentage significantly higher than that observed for CD4 (p<0.0001). By the Spearman correlation test, there was significant positive correlation between IL-17 and CD8 (rs = 0.5944, p=0.0415), but not between IL-17 and elastase, and IL-17 and CD4. In the double staining by immunofluorescence there was significantly more CD4+/IL17+ cells than CD8+/IL17+ cells (p=0.0250). In the periapical granulomas, CD4 labeling area percentage was significantly higher than those for elastase (p=0.0055), CD8 (p=0.0200), and IL-17 (p=0.0210). There was significant positive correlation between IL-17 and elastase (rs = 0.5604, p=0.0463), but not between IL-17 and the other markers. The most frequent double staining cells were CD4+/IL17+ cells in the comparison with CD8+/IL17+ cells (p=0.0114). In conclusion, IL-17 labeling area percentage is higher in the abscess than in the granuloma; in the granulomatous lesions the IL-17 expression is directly proportional to the neutrophil infiltration. These results may indicate that the Th17 response participates to the acute phase of the apical inflammatory process. Although there were significant differences regarding the predominant T lymphocytes types, the co-expression of IL-17 and CD4 in the both inflammatory processes may suggest that this CD4+ lymphocytes are the main responsible for IL-17 release in the analyzed periapical lesions.

Full textAim: To evaluate the management of pain in Endodontics by two studies: Article 1 - a randomized clinical trial comparing the analgesic efficacy of two opioids and non-opioid associations in the pain control of Acute Dentoalveolar Abscess (ADA); Article 2 - a systematic review investigating the efficacy and safety of analgesic therapy in the management endodontic pain.Methodology: The Article 1 included 24 patients that looked for emergency treatment in a university dental clinic. These patients were divided into two groups: Co / Pa - prescription of codeine (30 mg) + acetaminophen (500 mg) oral, every 4 h, during 3 days; Tr / Ac - prescription of tramadol hydrochloride (37.5 mg) + acetaminophen (500 mg) as the previous group. Pain scores were recorded by the patient at 6, 12, 24, 48, and 72 h after treatment, in a pain diary, using the Visual Analogue Scale (VAS). The Article 2 was conducted in electronic databases, gray literature, and references of retrieved articles to analyze randomized clinical trials or systematic reviews with or without meta-analysis. One arms of the therapy should have comprised an anti-inflammatory or analgesic drugs, orally administered by adults, in order to control moderate to severe pain, measured by Visual Analogue Scale, cause by endodontic problems . Data were collected regarding the characteristics of the sample, scores of pretreatment pain, characteristics of compared groups, methodological quality aspects, additional analgesic use, and frequency of adverse events. Descriptive and inferential analyzes were performed. Results: In Article 1, in both groups there was a reduction in the pain scores over time. For Co/Ac group, it was found a significant reduction in the scores at 12, 24, 48, and 72 hours after treatment (P <0.05). The scores at 48 and 72 hours were lower, compared to immediate treatment and scores at 6 hours after treatment (P <0.05). In the Tr/ Ac group, the scores decreased as the time is increasing (P <0.05). For all time intervals tested, the groups were not significantly different (P> 0.05). Both treatments were effective in controlling pain caused by ADA. The association Tr/ Ac presented itself less secure. In Article 2, a total of 431 references and 419 abstracts were reviewed, then only 14 articles were read in full. From these articles it was excluded 5 and 9 trials met the inclusion criteria. These studies compared acetaminophen, NSAIDs (ibuprofen, flurbiprofen, ketorolac tromethamine, etodolac, and tenoxicam), prednisolone, and analgesic tramadol associations for treating moderate to severe endodontic pain. It was observed that drugs were administered before or after endodontic therapy. In 8 studies, the control group was placebo and 8 studies used single dose regimen to assess pain control. In all clinical trials, the primary outcome analyzed was the reduction of scores in pain and secondary outcomes were the utilization of additional medication and adverse reactions. It was possible to establish a significant relationship between use of additional analgesics and periapical diagnosis. When the administration occurred before the endodontic procedure no adverse events were observed. When it was administered after the procedure, adverse reactions were reported in 2 of 3 trials included in the analysis. Conclusion: The Article 1 suggests that, considering analgesic efficacy and safety function, the association codeine/ acetaminophen is more effective for the control moderate to severe pain, at the treatment of ADA in evolution. The Article 2 found that there is a lack of RCTs in Endodontics using the same methodological standard to define a systemic treatment protocol of endodontic pain.

Resumo: Canais radiculares infectados tipicamente abrigam uma microbiota mista, composta principalmente por espécies anaeróbias. O papel das bactérias e seus subprodutos no desenvolvimento e perpetuação das infecções endodônticas já está bem estabelecido. Pesquisas têm sido realizadas para correlacionar a presença de bactérias em canais radiculares infectados com sinais e sintomas clínicos. A proposta do presente estudo foi investigar a composição da microbiota de canais radiculares infectados, associados a abscessos periapicais, e a possível correlação entre espécies bacterianas específicas com as fases dos abscessos, além de realizar testes de sensibilidade antimicrobiana das bactérias isoladas. As amostras microbiológica foram coletadas de 30 canais radiculares usando pontas de papel estéreis, transportadas em VMGA, diluídas, plaqueadas e incubadas em câmara de anaerobiose. Colônias microbianas foram isoladas, caracterizadas e identificadas por métodos padronizados. Cento e dezessete bactérias foram encontradas, sendo 75 (64,1 %) anaeróbias estritas. Uma ou mais (máximo de 10) espécies bacterianas foram encontradas em 29 (96,6%) canais radiculares infectados associados a abscessos periapicais, confirmando a característica polimicrobiana das infecções endodônticas. As bactérias anaeróbias mais freqüentemente isoladas foram: Peptostreptococcus prevotii (43,3%), Peptostreptococcus micros (30%), Fusobacterium necrophorum (23,3%). Embora menos freqüentes, bactérias facultativas como Gemella morbillorum (30%) e Streptococcus mitis (20%) também foram encontradas. Contudo, a análise estatística não encontrou relação entre presença dos abscessos periapicais com qualquer das espécies bacterianas identificadas (p>0,05). As espécies mais prevalentes Peptostreptococcus prevotii e Fusobacterium necrophorum foram testadas quanto à suscetibilidade antimicrobiana através do método do Etest, utilizando os seguintes antibióticos: benzilpenicilina, amoxicilina, amoxicilina + ácido clavulânico, metronidazol e clindamicina. Ps. prevotii e F. necrophorum apresentaram-se sensíveis a todos os antibióticos testados. Apesar da ausência de significância estatística, nossos resultados indicaram predominância de bactérias anaeróbias Gram-positivas e a presença de microbiota mista nos canais radiculares infectados associados a abscessos periapicais. Os testes de suscetibilidade antimicrobiana revelaram a presença de sensibilidade bacteriana entre as espécies Peptostreptococcus prevotii e Fusobacterium necrophorum aos antibióticos benzilpenicilina, amoxicilina, amoxicilina + ácido clavulânico, metronidazol e clindamicina
Abstract: Infected dental root canais typically harbour a mixed flora, including many anaerobic species. The role of these microorganisms and their by-products in the development and perpetuation of pulp and periapical diseases has already been well established. Efforts have been made in order to correlate bacteria present in infected dental root canais to clinical signs and symptoms. The present study was outlined to identify microorganisms present in root canais associated to periapical a bscesses , the correlation specific bacteria species with the phases of this inflammatory acute process, signs and symtoms and, to test the susceptibility of this microbiota to antibiotics. Microbiological samples were collected from 30 root canais using sterile paper points, transported in VMGA and diluted, plated and incubated in an anaerobic chamber. Microbial colonies were then purified, characterised and identified by established methods. One hundred seven different bacterial species were recovered, being 75 (64.1 %) strict anaerobes or microphilic species. One or more (maximum of 10) bacterial species were recovered from 29 (96.6%) root canais, showing the polymicrobial characteristic of dental infections. The anaerobes most frequently isolated were: Peptostreptococcus prevotii (43.3%), Peptostreptococcus micros (30%), Fusobacterium necrophorum (23.3%). Although less frequent, facultative bacteria as Gemella morbillorum (30%) e Streptococcus mitis (20%) were also found. However, statistical analysis by a Pearson X2 test or a one-sided Fisher's exact test did not find statistical relationship between any bacterial specie identified and the presence of periapical abscesses (p>0.05). Antibiotic sensitivity of Peptostreptococcus prevotii e Fusobacterium necrophorum was accomplished with the E-test System. These bacterial isolates were tested for their susceptibility/resistance to benzylpenicilin, amoxiciln, amoxicilin combined with clavulanate and clindamycin. The species Peptostreptococcus prevotii and Fusobacterium necrophorum were susceptible to ali tested antibiotics. In spite of the lack of statistical significance, our results indicated predominance of Gram-positive anaerobic bacteria at the mixed microflora present in dental root canais associated with periapical abscesses. Antibiotic susceptibility data showed Peptostreptococcus prevotii and Fusobacterium necrophorum susceptibility to ali tested antibiotics

Resumo: O objetivo deste estudo foi investigar a composição da microbiota de canais radiculares infectados associados a abscessos periapicais; analisar a correlação entre espécies bacterianas específicas com a localização clínica dos abscessos periapicais, sinais e sintomas e testar a suscetibilidade de bactérias anaeróbias estritas prevalentes. As amostras microbiológicas foram coletadas de 60 canais radiculares usando pontas de papel estéreis, transportadas em RTF, diluídas, plaqueadas e incubadas em câmara de anaerobiose. Colônias microbianas foram isoladas, caracterizadas e identificadas por métodos padronizados. Das 287 diferentes espécies bacterianas, 201 eram anaeróbias estritas. Uma ou mais (máximo de 14) espécies bacterianas foram recuperadas de 59 (98,3%) canais radiculares, confirmando a característica polimicrobiana das infecções endodônticas. As bactérias anaeróbias estritas mais freqüentemente isoladas foram: Peptostreptococcus prevotii (22/60), Peptostreptococcus micros (19/60), Fusobacterium necrophorum (19/60). Embora menos freqüentes, bactérias facultativas como Gemella morbillorum (19/60), Streptococcus mitis (13/60), e Streptococcus sanguis (11/60)também foram encontradas. O teste de Pearson ou teste exato de Fisher mostrou que houve relação positiva de algumas espécies bacterianas com a localização do abscesso periapical, bem como, com alguns sinais e sintomas de origem endodôntica (p<0,05). Os resultados indicaram predominância de bactérias anaeróbias Gram-positivas e a presença de microbiota mista nos canais radiculares infectados associados a abscessos periapicais. O método do E-test revelou sensibilidade bacteriana das espécies testadas aos antibióticos benzilpenicilina, amoxicilina, amoxicilinalclavulanato de potássio, metronidazol, clindamicina e cefaclor, contudo, certos microrganismos foram resistentes a azitromicina e eritromicina. Enquanto que, nenhum dos microrganismos testados produziu 'beta¿-lactamase
Abstract: The aim of this study was to investigate the composition of the microbiota of infected root canaIs associated with periapical abscesses, to investigate the correlation of specific species of bacteria with the clinical localization of the periapical abscesses, signs, and symptoms, and to test the susceptibility of prevalent strict anaerobic bacteria isolated. Microbiological samples were collected from 60 root canals using sterile paper points, transported in RTF and diluted, plated and incubated in an anaerobic chamber. Microbial colonies were then purified, characterized and identified by established methods. Of the 287 different bacterial species recovered, 201 were strict anaerobes or microphilic species. One or more (maximum of 14) bacterial species were recovered from 59 (98.3%) root canals, showing the polymicrobial characteristic of endodontic infections. The most frequently strict anaerobes isolated were: Peptostreptococcus prevotii (22/60), Peptostreptococcus micros (19/60), Fusobacterium necrophorum (19/60). Although less frequent, facultative bacteria such as Gemella morbillorum (19/60), Streptococcus mitis (13/60), and Streptococcus sanguis (11/60) were also found. The Pearson X 'POT. 2¿ test or Fisher's exat test showed positive relationship among some bacterial species and the localization of periapical abscesses as well as with some endodontic signs and symptoms (p<0.05). Results indicated predominance of Gram-positive anaerobic bacteria in the mixed microbiota of dental root canals associated with periapical abscesses. The E-test revealed bacterial susceptibility to benzylpenicillin, amoxicillin, amoxicillin/potassium clavulanate, clindamycin and cefaclor. All microorganisms tested did not produce 'beta¿-lactamase
