Abstract
Liver diseases are a group of major metabolic and immune or inflammation related diseases caused due to various reasons including infection, abnormalities in immune system, genetic defects, and lifestyle habits. However, the cause-effect relationship is not completely understood in liver disease. The role of microbiome, particularly, the role of gut and oral microbiome in liver diseases has been extensively studied in recent years. More interestingly, the presence of blood microbiome and tissue microbiome has been identified in many liver diseases. The translocation of microbes from the gut into the portal circulation has been attributed to be the major reason for the presence of blood microbial components and its clinical implications in liver disorders. Besides microbial translocation, Pathogen associated Molecular Patterns (PAMPs) derived from gut microbiota might also translocate. The presence of blood microbiome in liver disease has been reviewed earlier. However, the role of blood microbiome as a biomarker and therapeutic target in liver diseases has not been analysed earlier. In this review, we confabulate the origin and physiology of blood microbiome and blood microbial components in relation to the progression and pathogenesis of liver disease. In conclusion, we discuss the translational perspectives targeting the blood microbial components in the diagnosis and therapy of liver disease.

Abstract
The 'Focal Infection Era in Dentistry' in the late 19th and early 20th century resulted in widespread implementation of tooth extraction and limited the progress of endodontics. The theory proposed that bacteria and toxins entrapped in dentinal tubules could disseminate systemically to remote body parts, resulting in many types of degenerative systemic diseases. This theory was eventually refuted due to anecdotal evidence. However, lately there has been increased interest in investigating whether endodontic disease could have an impact on general health. There are reviews that have previously been carried out on this subject, but as new data have emerged since then, this review aims to appraise the available literature investigating the dynamic associations between apical periodontitis, endodontic treatment, and systemic health. The available evidence regarding focal infection theory, bacteraemia and inflammatory markers was appraised. The review also collated the available research arguing the associations of apical periodontitis with cardiovascular diseases, diabetes mellitus, adverse pregnancy outcome and autoimmune disorders, along with the effect of statins and immunomodulators on apical periodontitis prevalence and endodontic treatment prognosis. There is emerging evidence that bacteraemia and low-grade systemic inflammation associated with apical periodontitis may negatively impact systemic health, e.g., development of cardiovascular diseases, adverse pregnancy outcomes, and diabetic metabolic dyscontrol. However, there is limited information supporting the effect of diabetes mellitus or autoimmune disorders on the prevalence and prognosis post endodontic treatment. Furthermore, convincing evidence supports that successful root canal treatment has a beneficial impact on systemic health by reducing the inflammatory burden, thereby dismissing the misconceptions of focal infection theory. Although compelling evidence regarding the association between apical periodontitis and systemic health is present, further high-quality research is required to support and establish the benefits of endodontic treatment on systemic health.

Abstract
INTRODUCTION Infective endocarditis (IE) is still associated with high mortality, and antibiotic prophylaxis strategies are under intense debate. We evaluated the incidence of bacteremia after root canal preparation in teeth with necrotic pulps and apical periodontitis. METHODS Blood samples were taken before and 5 and 30 minutes after endodontic treatment in teeth with apical periodontitis from individuals at high (n = 21) or no risk (n = 11) for IE. The former received prophylactic antibiotic therapy. Bacteriologic samples were taken from root canals before chemomechanical preparation to confirm pulp infection. Samples were subjected to aerobic and anaerobic culture and quantitative real-time polymerase chain reaction (qPCR), the latter to determine the total bacterial and streptococcal levels. RESULTS Culture revealed no bacteremia in all individuals. Analysis by qPCR showed that bacterial DNA occurred in all root canal samples. qPCR showed a similar incidence of bacteremia between patients who received or did not receive prophylactic antibiotic therapy (P > .05). In blood samples taken 5 minutes after endodontic procedures, bacteria were detected in 2 of 11 (18%) individuals not taking antibiotics and in 4 of 21 (19%) patients under prophylaxis. After 30 minutes, the incidence of bacteremia decreased to 2 of 21 (10%) in patients taking antibiotics and was undetectable in patients at no risk of IE. The incidence of bacteremia by streptococci was identical as that for total bacteria. CONCLUSIONS No detectable bacteremia was evident by culture after treatment of infected root canals. Molecular analysis revealed bacterial DNA and streptococci in blood from some patients without a significant difference between individuals receiving or not receiving antibiotic prophylaxis.

Abstract
The Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures evidence-based clinical practice guideline was codeveloped by the American Academy of Orthopaedic Surgeons (AAOS) and the American Dental Association. This guideline replaces the previous AAOS Information Statement, "Antibiotic Prophylaxis in Bacteremia in Patients With Joint Replacement," published in 2009. Based on the best current evidence and a systematic review of published studies, three recommendations have been created to guide clinical practice in the prevention of orthopaedic implant infections in patients undergoing dental procedures. The first recommendation is graded as Limited; this recommendation proposes that the practitioner consider changing the long-standing practice of routinely prescribing prophylactic antibiotic for patients with orthopaedic implants who undergo dental procedures. The second, graded as Inconclusive, addresses the use of oral topical antimicrobials in the prevention of periprosthetic joint infections. The third recommendation, a Consensus statement, addresses the maintenance of good oral hygiene.

Abstract
BACKGROUND The authors examine the role of dental disease and nonsurgical dental procedures in the incidence and duration of bacteremia in children. METHODS The authors randomized a group of children to receive amoxicillin or a placebo before dental rehabilitation in an operating room setting. They collected eight blood draws at the following times: two minutes after intubation (draw 1); after dental restorations, pulp therapy and cleaning (draw 2); 10 minutes later (draw 3); and five draws during and after dental extractions (draws 4-8). The authors compared dental disease parameters and the type of dental procedures performed with the incidence and duration of bacteremia. RESULTS The authors enrolled 100 children (aged 1-8 years) in the study. The incidence of bacteremia from draw 2 was 20 percent in the placebo group and 6 percent in the amoxicillin group (P = .07), and the incidence from draw 3 was 16 percent in the placebo group and zero percent in the amoxicillin group (P = .03). Subjects with higher gingival scores were more likely to have a bacteremia for draw 2 (P = .01). The authors found that subjects in the group with bacteremia for draw 3 had undergone more pulpotomies than did subjects in the group without bacteremia for draw 3 (3 +/- 2.5 standard deviation [SD] versus 1.5 +/- 1.6 SD, P = .04), while they found almost no differences for draw 2. CONCLUSIONS This study suggests that gingival disease has an impact on bacteremia after dental restorations and prophylaxis. Although antibiotics have an impact, they do not eliminate bacteremia altogether.

Abstract
The purpose of this review is to evaluate the evidence implicating nonsurgical endodontic procedures in inducing infective endocarditis (IE). The literature is reviewed and findings about dental procedures that elicit bacteraemia [in particular root canal treatment (RCT)], sequelae of bacteraemia, relationship between IE and RCT and variation between antibiotic prophylaxis (AP) guidelines are highlighted. At present, there is still significant debate as to which dental procedures require chemoprophylaxis and what antibiotic regimen should be prescribed. Currently, there are insufficient primary data to know whether AP is effective or ineffective against IE. Practitioners are bound by current guidelines and medico-legal considerations. Thus, the profession requires clear, uniform guidelines that are evidence-based.

Abstract
OBJECTIVE: The aim of this randomized clinical trial was to evaluate the frequency of bacteriemia during endodontic treatment, with comparison between two techniques for biomechanical preparation of the root canal system. MATERIALS AND METHODS: The sample comprised 50 patients aged 16 to 52 years, of both genders, which were divided into 2 groups with 25 patients each. Group I underwent biomechanical preparation by the step-back technique, and Group II was treated by the rotary technique with nickel-titanium instruments (K3). Patients were submitted to antisepsis of the oral cavity with chlorhexidine digluconate and three samples of blood were collected for blood culture: preoperatively, immediately after the biomechanical preparation and 10 minutes later. The significance level adopted was 5.0%, and analysis was performed by descriptive and inferential statistics by means of the Fisher's exact test, Fisher-Freeman-Halton test and Student's t test. Data were analyzed on the Statexact and SPSS softwares. RESULTS: All blood cultures achieved before and immediately after preparation were negative. On the other hand, with regard to the blood cultures collected 10 minutes after preparation, one (4%) positive case was found for Group I. However, this difference was not statistically significant (p = 0.50). CONCLUSION: The frequency of bacteriemia was low and observed just for Group I.

Abstract
UNLABELLED Some dental procedures initiate a bacteraemia. In certain compromised patients, this bacteraemia may lead to distant site infections, most notably infective endocarditis. OBJECTIVE To investigate whether a detectable bacteraemia was produced during non-surgical root canal therapy. METHODS Thirty patients receiving non-surgical root canal therapy were studied. Three blood samples were taken per patient: pre-operatively, peri-operatively and post-operatively. In addition, a paper point sample was collected from the root canal. The blood samples were cultured by pour plate and blood bottle methods. The isolated organisms were identified by standard techniques. Blood samples were analysed for the presence of bacterial DNA by the polymerase chain reaction (PCR). In two cases where the same species of organism was identified in the root canal and the bloodstream, the isolates were typed by pulsed field gel electrophoresis (PFGE). RESULTS By conventional culturing, a detectable bacteraemia was present in 9 (30%) of the 30 patients who had no positive pre-operative control blood sample. In 7 (23.3%) patients, the same species of organism was identified in both the bloodstream and in the paper point sample from the root canal system. Overall, PCR gave lower detection rates compared with conventional culture, with 10 of 90 (11%) of the blood samples displaying bacterial DNA. PFGE typing was undertaken for two pairs of culture isolates from blood and paper points; these were found to be genetically identical. CONCLUSIONS Non-surgical root canal treatment may invoke a detectable bacteraemia.

Abstract
OBJECTIVE To provide a critical review of the current evidence that links dental treatment to infective endocarditis (IE) and appraise the risks of antibiotic chemoprophylaxis. DESIGN Retrospective analysis SETTING Mainly hospital based patients or subjects OUTCOME MEASURES The interrelationship between infective endocarditis and dental treatment is complex and in many instances uncertain. The risk from antibiotic chemoprophylaxis appear greater than the risk of contracting IE. RESULTS There is increasing evidence that spontaneous bacteraemia are more likely to cause IE in at risk patients than specific episodes of dental treatment. Antibiotic chemoprophylaxis may not necessarily reduce dental-induced bacteraemia and the protective effect if any from antibiotic cover may arise from an inhibitory action upon bacterial colonisation on the compromised cardiac valves. CONCLUSION There is increasing concern over the misuse of antibiotics in general and this has focused attention on chemoprophylaxis in dentistry to prevent IE. New evidence on dental-induced bacteraemia and the prevalence of IE in association with dental treatment raises further questions on the need to provide antibiotic cover in at risk patients. More prescriptive guidelines to define who is at risk from IE and what procedures require cover will help to reduce overprescribing of antibiotics and reduce the risks of their unwanted effects.

DATA SOURCES Published works in the medical and dental literature. STUDY SELECTION Evaluation of published clinical trials in endodontic and other pertinent literature. CONCLUSIONS Antibiotics are not routinely indicated in the practice of endodontics. Therapeutic antibiotics may be required as an adjunct to operative treatment when there is pyrexia and/or gross local swelling; they are only rarely indicated in the absence of operative intervention. Prophylactic antibiotics may be required for certain patients who are susceptible to serious infective sequaelae.

Abstract
REVIEW The focal infection theory was prominent in the medical literature during the early 1900s and curtailed the progress of endodontics. This theory proposed that microorganisms, or their toxins, arising from a focus of circumscribed infection within a tissue could disseminate systemically, resulting in the initiation or exacerbation of systemic illness or the damage of a distant tissue site. For example, during the focal infection era rheumatoid arthritis (RA) was identified as having a close relationship with dental health. The theory was eventually discredited because there was only anecdotal evidence to support its claims and few scientifically controlled studies. There has been a renewed interest in the influence that foci of infection within the oral tissues may have on general health. Some current research suggests a possible relationship between dental health and cardiovascular disease and published case reports have cited dental sources as causes for several systemic illnesses. Improved laboratory procedures employing sophisticated molecular biological techniques and enhanced culturing techniques have allowed researchers to confirm that bacteria recovered from the peripheral blood during root canal treatment originated in the root canal. It has been suggested that the bacteraemia, or the associated bacterial endotoxins, subsequent to root canal treatment, may cause potential systemic complications. Further research is required, however, using current sampling and laboratory methods from scientifically controlled population groups to determine if a significant relationship between general health and periradicular infection exists.

Abstract
Bacteremia originating from the oral cavity is common, but the role of bacteremia in the genesis of infective endocarditis and other distant site infections is unclear. Only a small percentage of oral flora have been associated with distant site infection. Important issues remain unresolved concerning the identification of patients at risk, the relative risk from invasive dental procedures versus naturally occurring bacteremia, and the impact of prophylactic antibiotics on the incidence, nature, magnitude, and duration of bacteremia from the oral cavity. This article addresses the controversies in infection management in patients at risk for distant site infection.

Abstract
We have previously demonstrated that anaerobic bacteria are the microorganisms most frequently isolated from blood following endodontic therapy of teeth with apical periodontitis. Phenotypic characterisation of the isolates suggested that the bacteria in the blood originated from the root canal. The present experiment using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was carried out in an effort to verify these findings, and to further study the microorganisms involved in endodontic bacteremias. Soluble cellular proteins were extracted from 11 reference strains and 26 bacterial isolates recovered from the root canal and blood. These included Propionibacterium acnes, Peptostreptococcus prevotii, Fusobacterium nucleatum, Prevotella intermedia. Actinomyces israelii, Streptococcus intermedius, Streptococcus sanguis. The electrophoretic patterns mostly confirmed the identity of the isolates as determined by the biochemical and antimicrobial resistance tests. Furthermore, with this typing method the species Prevotella intermedia and Prevotella nigrescens could be differentiated. These species had been recovered from both root canal and blood. Also, differences between subspecies of Fusobacterium nucleatum became evident with SDS-PAGE, and the results indicated that the organism recovered from the root canal and blood was Fusobacterium nucleatum subsp. vincentii. The electrophoretic patterns of the different organisms isolated from the root canal and the blood were similar, providing further evidence that the bacteria found in the blood originated from the root canal.

Abstract
Antibiotics can be used as an adjunct to endodontic treatment in a number of ways--locally, systemically and prophylactically. The local or intra-canal use of antibiotics in the form of medicaments is common. However, the commercially available agents for this purpose may not be the ideal mixtures. Systemic antibiotics should be restricted to patients who have local signs of infection, malaise and elevated body temperature. Prophylactic use of antibiotics has been recommended for patients 'at risk' of infective endocarditis, in some pre-surgical situations and following avulsion and replantation of teeth. The tendency towards indiscriminate antibiotic use should be discouraged. The use of broad spectrum drugs should be restricted so that these medications remain effective in serious situations.

Abstract
The American Heart Association committee recognizes that their regimens do not cover all situations. Each patient should be evaluated individually. The necessity for parenteral therapy or oral erythromycin to continue for 48 hours after all dental procedures should be reevaluated on a case-by-case basis. On the other hand, if the dental manipulation involves an infected site, perhaps antibiotic therapy should be continued until signs of the inflammation subside. Dentists and physicians must use their clinical judgement in prescribing antibiotics. However, as Kaye proposed, any deviation in prescribing antibiotics should be in the direction of higher doses or more effective antibiotics. In addition, practitioners must provide adequate patient education and follow-up. Unfortunately, a negligent dentist, a physician giving poor or inadequate advice, or a patient not following instructions may turn a simple dental procedure into a life-threatening situation and potential tragedy.

Abstract
A blood culturing technique was utilized to determine the incidence of bacteremia following the making of dental impressions with irreversible hydrocolloid (alginate). The results indicate that bacteremia is not produced by this impression procedure.

Abstract
Pulpectomies of deciduous teeth with severe pulpal necrosis should be considered as a possible treatment plan. Systemic and dental criteria have been devised to help the clinician to select cases in which successful results may be produced. A clinical success occurs when the pulpectomized tooth is painless, is firm in its alveolar socket, and is without a fistulous tract. Radiographically, any radiolucent area should be resolving with six months, and no pathologic root resorption should be observed. Research should determine whether pulpectomies may be done on children with severe systemic disease and should determine long-term consequences of underfilled and overfilled pulpectomies.

Abstract
A 48-year-old woman underwent root canal treatment of the upper left lateral incisor and lower right second premolar. Close to the conclusion of the endodontic treatment she complained about headaches. Later on, because of aggravation of her condition, with headaches, fever, malaise, weakness, and numbness of the right limbs, she was admitted to the hospital. The disease progressed to an epileptic state, with appearance of a right hemiparesis. A brain scan and carotid arteriogram revealed the presence of a mass occupying the left parietal space. Craniotomy disclosed an abscess containing yellow pus from which Streptococcus viridans was cultured. After thorough surgical cleansing of the area, removal of the bone for decompression, and treatment with ampicillin the patient improved gradually and slowly regained the mobility of her right side.
