J Am Dent Assoc. 28 These percentages are similar to other self-care devices: tooth brushing and flossing (20% to 68%), use of wooden toothpicks or sticks (20% to 40%), and mastication (7% to 51%). The extraction began with 5 to 7 seconds of tissue reflection followed by 8 to 10 seconds of tooth elevation, followed by removal in the usual manner. Introduction . The extraction-placebo group had a significantly greater number of positive cultures at 20 minutes (10%) than the extraction-amoxicillin (1%) and toothbrushing (1%) groups (P=0.001). A short summary of this paper. The mean age was 40 years, 58% were men, and 73% were black. As noted above, all analyzed samples were below the detection threshold of 104 CFU per milliliter of blood. This pattern persisted to 40 minutes. Conclusions— Although amoxicillin has a significant impact on bacteremia resulting from a single-tooth extraction, given the greater frequency for oral hygiene, toothbrushing may be a greater threat for individuals at risk for infective endocarditis. In healthy individuals, bacteremias can be qualified as transient. Google Scholar. There is ongoing debate concerning the health risks, cost-effectiveness, and practicality of the routine use of prophylactic antibiotics.3,4,33–35 The lack of efficacy data for this practice must be weighed against risk factors (eg, drug reactions), potential for resistant strains, and various economic costs to society from the routine use of antibiotics for common dental procedures.

The results indicate that methodology used for oral care before the HSCT and the practice of tooth brushing during the period were effective in preventing streptococcal bacteremia. Background— Antibiotic prophylaxis recommendations for the prevention of infective endocarditis are based in part on studies of bacteremia from dental procedures, but toothbrushing may pose a greater threat. Cumulative incidence of endocarditis-related bacteria from all 6 blood draws was 23%, 33%, and 60% for the toothbrushing, extraction-amoxicillin, and extraction-placebo groups, respectively (P<0.0001). Although brushing does not appear to have the same incidence and nature of bacteremia as a dental extraction, we found a substantial incidence (23%) of bacteremia of IE-causing species from this common daily oral hygiene activity. With the exception of 1 subject in the placebo group, polymicrobial blood cultures occurred only within the first 5 minutes of the procedure, albeit at a low rate in the brushing (2%) and extraction-amoxicillin (6%) groups compared with the extraction-placebo group (29%).

Although animal model data have established that the rate of infection of damaged heart valves is dependent on the inoculum size of the bacterial challenge, with larger inocula yielding higher infection rates, there are no data indicating the range of inocula that results in endocarditis in vulnerable patients. Transient bacteremia induced by toothbrushing a comparison of the Sonicare toothbrush with a conventional toothbrush. Compared with people who brushed only once a day or not at all, those who brushed twice a day had a … Bacteremia Associated With Toothbrushing and Dental Extraction. It is difficult to quantify the magnitude of bacteria that initially gain entrance to the circulation after dental procedures owing to factors such as heart rate, blood volume, proximity of the blood collection site to the source of the bacteremia, and the rapid bacterial clearance by the reticuloendothelial system. Tooth brushing, biopsy Short procedures where spillage of bacteria into bloodstream but immune system fixes w/in a few minutes . Although there are many reports that address bacteremia from dental extractions, considered the most invasive of dental office procedures, there are few such data on routine daily activities such as toothbrushing. Periodontal Disease and Atherosclerotic Vascular Disease: Does the Evidence Support an Independent Association? Therefore, there is the potential for bacteremia from tooth brushing alone to occur over two hundred times per year, by comparison with an average of less than two dental office visits per year per person in the United States. These results show that vigorous brushing increased bacteremia from one brushing … CONCLUSIONS The Sonicare induced significantly more bacteremias than manual toothbrushing. Bacteria commonly gain entrance to the circulation through ulcerated gingival crevicular tissue that surrounds the teeth.23 Although dental extractions are among the most likely of dental procedures to cause bacteremia, toothbrushing may disrupt a far larger surface area of gingival crevicular tissue. However, data on the incidence, duration, nature, and magnitude of bacteremia from non–IE-associated species and bacteria identified by nonmolecular means are of little or no help to clinicians or policy makers.31 We focused on the 32 bacterial species identified in the present study that were also on our list of 275 bacteria reported to cause IE, 11 (34%) of which have not been reported previously in studies of brushing or extractions.

Research output: Contribution to journal › Journal article › Research › peer-review When a patient was enrolled, the next envelope in sequence was opened and the treatment assignment implemented. Incidence of bacteremia after chewing, tooth brushing and scaling in individuals with periodontal inflammation. Second, although the number of bacterial CFU per milliliter of blood was always below 10 000, this does not exclude the possibility of significant differences in bacterial CFU per milliliter of blood below this threshold between the 3 groups, which might be important in terms of risk of heart valve colonization. The timing for the steps in the brushing and extraction procedures was strictly controlled. 7272 Greenville Ave. Dental scaling and extraction lead to bacteremia in 70% - 100% and tooth brushing leads to bacteremia in 40% of the children, where VGS were found in 50% of the cases (67, 68). PubMed journal article: Transient bacteremia consequent to tooth brushing in orthodontic patients. IE-related bacterial species identified in the present study blood draws occurred at: (1) baseline; (2) 1.5 minutes and (3) 5 minutes after initiation of brushing or extraction; and (4) 20 minutes, (5) 40 minutes, and (6) 60 minutes after completion of the brushing or extraction. Although amoxicillin has a significant impact on bacteremia resulting from a dental extraction, 33% of patients undergoing extraction after prophylaxis showed evidence of bacteremia, including infective endocarditis–related species.

Numbered boxes represent the number of positive cultures for that species at that time point. The relative risk for infective endocarditis from bacteremia during invasive office procedures such as dental extractions versus routine daily events such as toothbrushing is unknown. Our comprehensive search of the literature provided a list of 275 species of bacteria reported to cause IE, which we compared with the list of bacterial species identified in the present study. Incidence and duration of bacteremia at 6 time points from IE-related bacterial species. Don't cover your toothbrush or place it in a closed container until it is completely dry. Demographic and baseline clinical characteristics of participants are reported as means and SDs or frequencies and percentages. The 16S ribosomal RNA (rRNA) sequencing method was used for bacterial identification. Amoxicillin resulted in a significant reduction in the incidence of positive cultures at draws 2, 3, and 4 (P<0.0001), and it reduced the incidence of positive cultures by 69% (from 151 to 47) for all species and by 78% (106 to 23) for (viridans) streptococci (Table 2). Study protocol time line. There were more than twice as many complex extractions in the extraction-placebo group (19 versus 9) as in the extraction-amoxicillin group, which, although not statistically significant, suggests that 20% of the placebo group versus 9% of the amoxicillin group had a more invasive procedure.

Incidence data about bacteremia due to tooth brushing are only available from the mid-1970s, and the incidence ranges from 16% to 68% . Patients randomized to the brushing group had their dental extraction accomplished at the end of the study period, after the last blood draw, or on a subsequent visit. Download PDF. Historically, much of the emphasis on prevention of infective endocarditis (IE) has focused on the risk from dental and other nondental procedures.1 The American Heart Association (AHA) recommendations for antimicrobial prophylaxis for IE are controversial owing to the lack of definitive evidence for efficacy and because they are based largely on studies that used surrogate measures for risk.2–12 Studies of incidence, duration, nature (species), and magnitude of bacteremia from dental procedures are often in conflict because of variability in study design. Incidence figures for bacteremia in adults range from 0% to 100% for single-tooth extractions5,7,20–22 and from 0% to 57% for toothbrushing.13–15,17,19 There is no large, prospective comparison study of the incidence, duration, nature, and magnitude of bacteremia from procedures with these perceived extremes of invasiveness. Subsequent blood draws of 20 mL were taken at 1.5 minutes and at 5 minutes after the initiation of surgery or brushing. The purpose of the present study was to compare the incidence, duration, nature, and magnitude of bacteremia from endocarditis-related bacteria during and after brushing or a single-tooth extraction and to determine the impact of AHA-recommended amoxicillin prophylaxis on the incidence, duration, nature, and magnitude of bacteremia after a single-tooth extraction. There was a significant drop in the incidence of positive cultures at 20 minutes in all 3 groups (all P<0.0001), and this continued at 40 and 60 minutes, with little difference between the brushing and extraction-amoxicillin groups at draws 4 to 6. IE-related bacterial species identified in the present study blood draws occurred at: (1) baseline; (2) 1.5 minutes and (3) 5 minutes after initiation of brushing or extraction; and (4) 20 minutes, (5) 40 minutes, and (6) 60 minutes after completion of the brushing or extraction.

Search for more papers by this … The authors had full access to the data and take full responsibility for its integrity. Bacteremia has been documented during many diagnostic procedures (6) (2% to 5%) including endoscopic retrograde cholangio-pancreatography but can follow such trivial daily events as tooth brushing and defecation. ryday” bacteremia from chewing, tooth brushing and flossing is much more significant. Therefore, given the far greater frequency for oral hygiene than for dental office procedures, toothbrushing appears to be a greater … Additional blood samples (20 mL) were drawn 20, 40, and 60 minutes after the end of the procedure. Methods and Results— In this double-blind, placebo-controlled study, 290 subjects were randomized to (1) toothbrushing, (2) single-tooth extraction with amoxicillin prophylaxis, or (3) single-tooth extraction with identical placebo. Amoxicillin resulted in a significant decrease in positive cultures (P<0.0001). Of the 98 bacterial species identified, 32 species overlapped with our list of 275 species reported to cause IE, and the following results focus on these 32 oral bacterial species. The duration of bacteremia likely reflects the nature and number of bacteria that enter the circulation, as well as multiple other host factors such as immune responses. The gingival tissue of each tooth was examined at the distofacial papilla, mesiofacial papilla, facial margin, and lingual margin. We are not aware of any differences between racial groups in terms of oral bacterial flora in disease or health, and we therefore believe that these data are easily extrapolated to other racial and ethnic groups. Patients presented to our urgent care service with the need for extraction of at least 1 erupted tooth. Each tooth was measured from the mesial and mesiobuccal sites, with the average representing the tooth score. By continuing to browse this site you are agreeing to our use of cookies. There are potential limitations to the present study. The magnitude of bacteremia for all 3 study groups was <104 colony-forming units per milliliter of blood, which suggests that brushing and single-tooth extraction are similar from the standpoint of magnitude.

Dental and periodontal disease parameters included mean periodontal pocket depths for all remaining teeth, calculus scores (range 0 to 3), gingival erythema scores (range 0 to 3), and plaque scores (range 0 to 3; Table 1). For the brushing arm of the study, subjects brushed all surfaces of the teeth adjacent to the gingiva with a new toothbrush (without toothpaste) for 2 minutes, timed as 30 seconds for each of the maxillary and mandibular quadrants of teeth. All false-positive bottles (ie, bottles that were signaled positive but for which the subculture was negative) were further incubated for a total of 2 weeks. Incidence of bacteremia after chewing, tooth brushing and scaling in individuals with periodontal inflammation. https://doi.org/10.1161/CIRCULATIONAHA.107.758524, National Center The sensitivity of the method was 25 colony-forming units (CFU) per polymerase chain reaction, which corresponds to 103 to 104 CFU per milliliter of blood. There are potential limitations to the present study. Blood was drawn for bacterial culturing and identification at 6 time points before, during, and after these interventions. The organisms cultured after tooth brushing are listed in Table 4. Baseline data included demographics, medical history, and a thorough clinical and radiographic examination of the teeth and periodontium. The risk of transient bacteremia following gastrointestinal endoscopic procedures is lower than that caused by many routine activities in daily life. This site uses cookies.
