Dh. Fine et al., ASSESSING PREPROCEDURAL SUBGINGIVAL IRRIGATION AND RINSING WITH AN ANTISEPTIC MOUTHRINSE TO REDUCE BACTEREMIA, The Journal of the American Dental Association, 127(5), 1996, pp. 641
In this controlled clinical study, the authors examined the effect of
subgingival irrigation and rinsing With an antiseptic mouthrinse befor
e ultrasonic scaling of a quadrant containing inflamed gingivae. The r
esults showed that pre-procedural subgingival irrigation and rinsing c
an significantly reduce the level of bacteremia associated with ultras
onic scaling. These results support the American Heart Association's r
ecommendation of adjunctive subgingival irrigation prior to invasive p
rocedures in patients at risk of developing bacterial endocarditis.
