Abstract:

Introduction: Bacteria are the most common pathogens responsible for pulpal necrosis and periapical disease conditions. The importance of eradicating bacteria and their endotoxic by-products has been highlighted in numerous studies. Aim: The aim of this in vitro study was to establish the efficacy of six endodontic disinfection protocols in eradicating Enterococcus faecalis from single root canals of human teeth. Materials and Methods: Endodontic access cavities were prepared on 86, extracted, single rooted, human teeth. Root canal preparation was done using nickel titanium rotary files. Each

Abstract:

Abstract Microbial infection in dental root canal induces an inflammatory reaction called apical periodontitis. In post-treament disease, Enterococcus faecalis is the most commonly found organism, which may survive well in root canal despite calcium hydroxide paste medication. In these cases, effective irrigation or repeated chlorhexidine medication are recommended. New medications with long-lasting antimicrobial activity are needed for the treatment of persistent root canal infections. 2-hydroxyisocaproic acid (HICA) is a protein fermentation product of lactobacilli and few other bacterial or

Aim: To investigate the microbial diversity of primary and secondary root canal infections using high throughput sequencing on the illumina MiSeq and culture methods. Methods: 19 subjects were recruited for the study; ten primary infections and nine secondary infections. Samples were collected before chemo-mechanical preparation (S1) and prior to obturation (S2), respectively. Microbiological culture aliquots were serially diluted and inoculated onto various non selective and selective media for total anaerobic and total aerobic counts. For high throughput sequencing, DNA was extracted and the

As infeções endodônticas envolvem a invasão e multiplicação de microrganismos na polpa dentária e tecidos periapicais sendo responsáveis por dois tipos de patologias: as patologias pulpares e as patologias periapicais. Relativamente às patologias pulpares destacam-se a pulpite reversível, a pulpite irreversível e a necrose pulpar. Quanto às patologias periapicais, destacam-se o abcesso apical agudo, o abcesso apical crónico, a periodontite apical aguda, a periodontite apical crónica, o granuloma perirradicular e o quisto perirradicular. As doenças pulpares e periapicais apresentam manifestaçõ

Abstract:

Indiana University-Purdue University Indianapolis (IUPUI)<br>Root canal therapy is a recommended treatment for apical periodontitis. Root canal failure can occur as a result of microbial leakage. Resilon, a resin based root canal obturating cone material introduced in 2004 attempts to minimize leakage by a unique bonding method of the resin sealer to both the core material and to the dentin of the canal walls. Resilon has no bactericidal or antimicrobial effect15. Furthermore, it has been shown that Resilon is susceptible to alkaline and enzymatic hydrolysis as well as bacterial degradation

Abstract:

Indiana University-Purdue University Indianapolis (IUPUI)<br>Introduction: One of the main objectives of endodontic therapy is to reduce microbes and remove inflamed pulpal tissue within the root canal system (RCS). This is accomplished through chemomechanical debridement of the RCS using hand and rotary instrumentation along with an antimicrobial irrigant. Today, the most commonly used irrigant is sodium hypochlorite (NaOCl), often at concentrations toxic to human cells. The use of ozone as an endodontic irrigant is a novel technique that has been proven to be antimicrobial against several

Indiana University-Purdue University Indianapolis (IUPUI)<br>The primary goal of root canal treatment is to eliminate microbes from the root canal system, which is the cause of pulpal and periapical infections. Research shows that after a single visit of chemomechanical debridement microbes continue to remain within the canal system. An interappointment medication step has been advocated to maximize potential elimination of microbes within the root canal system. Previous studies have shown propolis to be antibacterial against common endodontic microbes. Studies have shown trends in different m
