Objectives. The purpose of this study is to verify the efficacy of a probiotic product in the selection of the oral flora and to ascertain if chromogenic bacteria could be eliminated through professional oral hygiene procedures in combination with chlorhexidine. Materials And Methods. The study is a randomized controlled clinical trial. Ten patients aged between 25 and 35 years were examined (5 males and 5 females). They presented extrinsic pigmentations with a black line presumably to be ascribed to chromogenic bacteria. Results And Conclusions. The results obtained by splitting the sample into two groups are presented. Probiotics are efficient when combined with a correct professional and home care protocol of oral hygiene. It is assumed, however, that the effect of the probiotic persists until it is administered and wanes when the administration is suspended.
