Eksperimentel: gingivitis mouth rinse
|
Before local oral anesthesia and periodontal instrumentation individuals performed a single oral rinse (15mL of 0.12% chlorhexidine gluconate for 30 seconds).
Debridement procedures were carried out with manual Gracey and McCall curettes and Hirschfield files.
Individuals only received local oral anesthesia before periodontal instrumentation.
Debridement procedures were carried out with manual Gracey and McCall curettes and Hirschfield files.

Changes on viable bacterial levels in blood
Tidsramme: 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.

Changes on levels of bacterial DNA in blood
Tidsramme: 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.
