Bacteremia in Periodontal Patients

11. August 2014 aktualisiert von: University of Taubate

Influence of Pre-procedural Oral Rinse in the Induced Bacteremia by Periodontal Instrumentation: a Randomized Clinical Trial

Bacteremia represents the presence of live germs in the blood stream. Patients with gum disease show damaged tissues and seem to be more susceptible to bacteremia. In fact, daily activities such as mastication can induce bacteremia in these patients. Dental procedures related to bleeding also induce bacteremia. However, there are many questions that should be clarified. Among them, clinical strategies that are able to reduce the levels of germs in blood should be determined. This desirable effect could be particularly important for some patients, for example, for those at higher risk for endocarditis. Therefore, this study tested if 0.12% chlorhexidine solution used as a single mouth rinse before dental instrumentation could reduce the levels of bacteria in the blood. In addition, the occurrence and magnitude of bacteremia in patients with gum disease were investigated by two different laboratorial techniques. After receiving verbal and written explanations and after signed the informed consent form, 80 systemically healthy volunteers diagnosed with gum disease having dental plaque and tartar were randomly allocated in one the following groups: a) mouth-rinse use and dental instrumentation and b) dental instrumentation with no mouth rinse. In a preliminary visit volunteers underwent a complete periodontal examination which included clinical measurements (inflammatory and debris accumulation indicators), microbial (tongue and dental plaque samples collected with paper points), saliva (to determine volume and biological indicators) and gingival crevicular fluid sampling (to monitor gingival inflammation profile). In the next visit, dental instrumentation was performed under local anesthesia, after the mouth rinse single use in the most diseased periodontal teeth/quadrant. Blood samples were collected before any dental procedure, 2 and 6 minutes after dental instrumentation. Oral hygiene instructions and periodontal treatment were performed in additional visits according to individual needs. Finally, the relation between bacteremia and several indicators of periodontal status was investigated.

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Changes on viable bacterial levels in blood
Zeitfenster: 2 and 6 minutes
To check a possible antimicrobial effect after a single mouth rinse use, the levels of viable anaerobic and aerobic bacterial cels were compared between 0 and 2 minutes, 0 and 6 minutes and between 2 and 6 minutes. Blood samples were collected and spread out onto agar plates to determine total levels of aerobic and anaerobic bacteria. Bacterial levels at 2 and 6 minutes were compared between volunteers who performed the pre-procedural rinse and who not.
2 and 6 minutes

Sekundäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Changes on levels of bacterial DNA in blood
Zeitfenster: 2 and 6 months
To check a possible antimicrobial effect after a single mouth rinse use, the levels of bacterial DNA in blood samples were compared between 0 and 2 minutes, 0 and 6 minutes and between 2 and 6 minutes. Blood samples were collected and analyzed by real time PCR (polymerase chain reaction) to determine total bacterial load and levels of target periodontal pathogens. Bacterial levels at 2 and 6 minutes were compared between volunteers who performed the pre-procedural rinse and who not.
2 and 6 months
