Protective and destructive immune reactions in apical periodontitisApical periodontitis is initiated primarily by the mixed microflora of infected root canals. Continuous flow of bacteria and their products through the apical foramen induces influx, activation and coordinated interaction of immune‐inflammatory cells within the periapical area. Successful mobilization of host defense mechanisms prevents abundant extraradicular bacterial invasion. However, ... ...

Bacterial reduction and persistence after endodontic treatment proceduresBacteria that persist after endodontic disinfection procedures may lead to treatment failure. Over 50% of the bacteria found in endodontic infections are as‐yet‐uncultivated so investigations of bacteria that endure treatment procedures should include techniques that side‐step cultivation. This culture‐independent study evaluated the bacterial reduction promoted by intracanal disinfection ... ...

Probiotic bacteria affect the composition of salivary pellicle and streptococcal adhesion in vitroIntroduction: The use of probiotic bacteria is increasing worldwide and at least some of them can transiently colonize the oral cavity. Several studies have shown that probiotic bacteria, which are often thought of in relation only to intestinal health, can also affect the oral ecology, but the mechanisms for this are largely unknown. The aim of this study was to in...

Caries‐related plaque microcosm biofilms developed in microplates In vivo dental plaque biofilms consist of complex communities of oral bacteria that are a challenge to replicate in vitro . The aim of this investigation was to establish human dental plaque microcosms in microplates to reflect conditions that are relevant to dental caries. Microcosm plaque biofilms were initiated from the saliva of two... ...

Differential gene expression of human β‐defensins (hBD‐1, ‐2, ‐3) in inflammatory gingival diseasesAntimicrobial peptides, like human β‐defensins, play an important role in the epithelial innate defense response. The aim of the present study was to investigate the quantitative expression of human β‐defensin‐1, ‐2, and ‐3 in inflammatory gingival diseases. Gingival biopsies were obtained from patients with healthy gingiva (n = 10), patients with gingivitis (...

Prevalence of mutans streptococci in one‐year‐old childrenColonization with mutans streptococci was studied in 1095 1‐year‐old children living in suburban Stockholm. During a scheduled vaccination appointment at a child health centre, a bacterial sample was obtained from the child's tongue and a structured questionnaire was completed by the accompanying parent. Six percent of the subjects were colonized with mutans streptococci. The variables mos... ...

Use of polymerase chain reaction techniques and sodium dodecyl sulfate‐polyacrylamide gel electrophoresis for differentiation of oral Lactobacillus speciesBackground/aims: The genus Lactobacillus has been associated with dental caries in humans, although it is seldom speciated due to lack of simple and nonlaborious identification methods. A considerable heterogeneity among Lactobacillus species has been demonstrated. The purpose of this study was to develop simple ...

Antimicrobial susceptibility of major pathogens of orofacial odontogenic infections to 11 β‐lactam antibioticsIn this study, we evaluated the current effectiveness of 11 β‐lactam antibiotics for treatment of orofacial odontogenic infections by determining the antimicrobial susceptibility of the major pathogens. The antimicrobial susceptibilities of viridans streptococci (n = 47), Peptostreptococcus (n = 67), ...

Improved accuracy in terminal restriction fragment length polymorphism phylogenetic analysis using a novel internal size standard definitionBackground: Terminal restriction fragment length polymorphism (T‐RFLP) analysis is commonly used to analyze microbial communities, including oral microflora. However, accurate identification of terminal restriction fragment (T‐RF) origins is prevented by unpredictable errors in sizing, thus necessitating the clone library analysis. To minimize sizing errors, we prop...

Adherence to and penetration through endothelial cells by oral treponemesOral spirochetes were co‐incubated with monolayers of endothelial cells seeded into multiwell plates or onto filters mounted in plastic chambers. Attachment was assessed using an enzyme‐linked immunosorbent assay and scanning electron microscopy. Invasiveness was determined by monitoring media beneath filters within chambers for spirochetes using darkfield microscopy. Transmission electron... ...
