ABSTRACT The bacteriology of 57 dentoalveolar infections was studied using optimal techniques to collect, transport and process specimens. There was an average of 4 bacterial species per specimen, and only 1/3 of the specimens held aerobes. Among the aerobic bacteria, streptococci dominated and among the anaerobes the Gram-negative rods, Bacteroides ruminicola and Fusobacterium nucleatum, were most frequently isolated followed by Gram-positive cocci, in particular Streptococcus intermedius. All aerobic isolates were resistant to penicillins but sensitive to clindamycin and tinidazole. The other anaerobic isolates were sensitive to penicillins but showed varying susceptibility to erythromycin and doxycycline. Tinidazole was effective against all anaerobic Gram-negative rods. The presence of volatile fatty acids in pus from dentoalveolar infections was found to be of presumptive value for the diagnosis of anaerobic infections. Direct gas-liquid chromatographic analysis of pus is recommended as a routine procedure for preliminary diagnosis of anaerobic dentoalveolar infections.

    Article: Black-pigmented Bacteroides spp. in human apical periodontitis.

    ABSTRACT: The incidence of black-pigmented (BP) Bacteroides spp. in 62 human dental root canal infections (35 acute and 27 clinically asymptomatic cases of apical periodontitis) in 57 adults was studied. Altogether 37 strains of BP Bacteroides were found in 31 infections, always in mixed anaerobic infections. Two different BP Bacteroides species were present in six infections. B. intermedius was most frequently isolated (15 of 62 canals; 24%) followed by B. denticola which was present in 12 cases. Asaccharolytic BP Bacteroides species, B. gingivalis and B. endodontalis, were found in eight cases. BP Bacteroides species were found both from symptomatic and asymptomatic infections, but there were also several symptomatic cases from which BP Bacteroides species were not isolated. B. gingivalis and B. endodontalis were present only in acute infections, B. intermedius was found both in symptomatic and asymptomatic infections, and B. denticola occurred mostly in asymptomatic infections. BP Bacteroides species were isolated initially from 9 of the 11 teeth with symptoms at 1 week, but only from 22 of the 51 teeth that were symptomless at 1 week. Two strains of B. denticola were resistant to penicillin G at a concentration of 2.4 micrograms/ml, but the MIC of penicillin G for all other strains was 0.6 micrograms/ml or lower. Forty-two randomly selected patients received penicillin V (oral administration, 650 mg, three times daily) during the first week of endodontic therapy. Penicillin had no effect on the occurrence of symptoms after 1 week compared with the control group (20 patients).

    Article: Penicillin resistance in the subgingival microbiota associated with adult periodontitis.

    [show abstract] [hide abstract]
    ABSTRACT: In this investigation, the penicillin-resistant and beta-lactamase-producing subgingival microbiota associated with adult periodontitis was identified, and the impact of a recent exposure to penicillin on the recovery of resistant organisms from this microbiota was assessed. Subjects with adult periodontitis were examined clinically and microbiologically. Twenty-one subjects had a documented history of penicillin therapy within the previous 6 months whereas an additional 21 subjects had no history of antibiotic use within 1 year. Subgingival plaque samples were cultured anaerobically on nonselective and penicillin-containing elective media. MICs and beta-lactamase production were determined for the isolates from the elective medium. The penicillin-resistant microbiota consisted primarily of gram-negative organisms, including Bacteroides, Veillonella, Haemophilus, Eikenella, and Capnocytophaga species. The prevalence (P less than 0.05) and proportions (P less than 0.005) of both penicillin-resistant pigmented Bacteroides and Veillonella species were significantly greater in subjects with recent penicillin exposure. Of the penicillin-resistant genera identified, beta-lactamase production was detected in species of pigmented Bacteroides, Capnocytophaga, and Streptococcus. The prevalence of beta-lactamase-producing Bacteroides species was significantly greater in subjects with recent penicillin exposure (P less than 0.05). Of the antibiotics examined, no single agent was uniformly effective against all of the penicillin-resistant strains, but metronidazole and clindamycin were active against all of the penicillin-resistant pigmented Bacteroides strains.

    Article: Persistent, recurrent, and acquired infection of the root canal system post‐treatment
    Markus Haapasalo, Trude Udnæs, Unni Endal
    [show abstract] [hide abstract]
    ABSTRACT: Apical periodontitis is an inflammatory process in the periradicular tissues caused by microorganisms in the necrotic root canal. Accordingly, to achieve healing of apical periodontitis, the main goal of the treatment must be elimination of the infection and prevention of re-infection. As shown by recent epidemiological studies in several countries around the world, post-treatment endodontic disease is a far too common finding. To understand the reasons for survival of resistant bacteria in the filled root canal, it is important to know in detail the interaction between treatment procedures and the root canal flora in primary apical periodontitis. Therefore, in the first half of this review, the focus is placed on control of infection in primary apical periodontitis. This is followed by a detailed description of the resistant root canal microflora and a discussion about the present and future strategies to eliminate even the most resistant microbes in post-treatment disease.
