Enterococcus faecalis-mediated biomineralized biofilm formation on root canal. Author information Article notes Copyright and License information Disclaimer. In the present study, it was not possible to obtain an ideal combination of results, infracanal the high heterogeneity of the adopted clinical protocols. In accordance with this study, other investigations also recovered microorganisms from teeth with endodontic infection after antimicrobial endodontic therapy 6 The success of infected root canal therapy is influenced by discrepancy gradients of microorganisms between the endodontic biofilm and the planktonic suspension Abstract The purpose of this paper is to discuss critically the antibacterial efficacy of intracanal medicaments on bacterial biofilm.

The variability between the employed methodologies, study selection, publication biases, absence of randomized controlled trial, access to all the information of the published experiments and the own nature of the essays, signalizes for some critical implications towards the equation of the problem.

Open in a separate window. Evidence-based dentistry involving systematic revkew or meta-analyses has been the ultimate goal to integrate the best available research evidence with clinical experience. Microbiologic analysis of teeth with failed endodontic treatment and the outcome of conservative re-treatment.

From a total of 91 articles, 8. Longitudinal studies signalize that there is yet no accurate solution to eliminate or disrupt the root canal bacterial biofilm.

Prospective studies were reviewed with regard to the efficacy of the intracanal medicaments on bacterial biofilm. The focus on answering clinical questions can be structured by means of problem, intervention, comparison and outcome. A guide to interpreting discordant systematic reviews.


Antibiotics as intracanal medicaments: a review.

For the electronic search strategy the terms presented in Table 1 were used as keywords in several combinations. Various obstacles on the analysis of the pertinent data for the included studies involved methodological data that were hidden and that present a relative degree of importance.

Microbial status of apical root canal system of intracnal mandibular first molars with primary apical periodontitis after one-visit-endodontic treatment.

A clinical question that supports the decision about the antibacterial efficacy of intracanal medicaments on bacterial biofilm cannot be answered using a critical longitudinal analysis of published articles. Biofilm, Intracanal medicaments, Antimicrobial efficacy.

However, the clinical effectiveness of these agents must be evaluated in the light of the complexity of root canal anatomy and polymicrobial nature of root canal infections. Coronal leakage of mixed anaerobic bacteria after obturation and post space preparation. Chavez kedicaments Paz, et al. Antibacterial effects of endodontic irrigants on black-pigmented Gram-negative anaerobes and facultative bacteria.

In order to develop new treatments to eradicate E. In vitro antimicrobial activity of sodium hypochlorite medicametns chlorhexidine against selected single-species biofilms. The susceptibility of oral bacterial biofilm to antimicrobial agents indicates the need to reproduce in vivo conditions where bacteria grow as biofilm on tooth surfaces Investigations have shown medicaemnts antimicrobial success intraacnal or failure 51130 of intracanal medicaments on bacterial biofilm, as well as the presence of biofilm on the entire external root apex surfaces in teeth with pulp necrosis and radiographically visible periapical lesions In vivo studies, in humans Related to the root canal biofilm Randomized controlled trials RCT Related to the efficacy of intracanal medicaments on biofilm English-language articles.

EM evaluation of bacterial biofilm and microorganisms on the apical external root surface of human teeth. National Center for Biotechnology InformationU. The search retrieved 91 related articles, of which 8. An in vitro evaluation of the ability of ozone to kill a strain of Enterococcus faecalis. Comparative evaluation of antimicrobial efficacy of sodium hypochlorite, MTAD, and Tetraclean against Enterococcus faecalis biofilm.


Surface adherence by bacteria to form biofilms intradanal a good example of bacterial adaptation.


Susceptibilities of Enterococcus faecalis biofilms to some antimicrobial medications. The findings highlight the importance and need for stringently applying non-antibiotic chemomechanical measures in order to disrupt the biofilm and reduce the intraradicular microbial load to the lowest possible level to ensure the most favorable long-term prognosis for treatment of infected root canals.

The difference in gradients of bacterial killing amongst the biofilm, planktonic suspension or pellet presentation was significant and dependent upon the agent, except for NaOCl and calcium hydroxide, in which no difference could be detected.

Other aspects that must be critically observed and judiciously analyzed are the biofilm model to test the antimicrobial endodontic medicaments, the biological indicator, and the time necessary for biofilm formation.

The requirement for its development includes studies in human subjects with definite clinical issues, using a critical longitudinal analysis of published articles. The purpose of this paper is to discuss critically the antibacterial efficacy of intracanal medicaments on bacterial biofilm. A major advantage is the protection that the biofilm provides to colonizing species from microorganisms competing for environmental factors, such as host defense mechanisms, and from potentially toxic substances in the environment, such as lethal chemicals or antibiotics.

Torabinejad M, Bahjri K. Table 4 describes in vitro research articles that were excluded for referring to different bacterial biofilm models, contamination time, root canal cleaning and shaping techniques, and therapeutic efficacy.
