الملخص EN

Background : Probiotic technology represents a breakthrough approach to maintaining oral health by utilizing natural beneficial bacteria commonly found in healthy mouth to provide a natural defense against those bacteria though to be harmful to periodontal tissue.

Data are still sparse on the probiotic action in the oral cavity.

The aim of study was the present study evaluated clinically the efficacy of probiotic type inarched yeast extract, and chlorhexidine mouth rinses on plaque. Material and method : Four strain of probiotics bacteria were used, Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus bulgaricus and bifidubacterium actiregularis, and grown in skim milk and plus 0.25, 0.5 % yeast extract individually, the cell free extract of each one of those treatments were add 1: 9 todiluted bacterial plaque taken from 5 subjects, to measure the effect of cell free extract on aerobic & anaerobic bacteria.

45 subjects with chronic periodontitis attend periodontal clinic in college of dentistry university of Baghdad (age 25-35) the trial design as 14 days comparative study between a probiotic and chlorhexidine. Result : add yeast extract increased the total count of 4 probiotic bacteria 16.25 -29.22 % , Cell free extract of Lb.

acidophilus probiotic skim milk dairy product was the most powerful in reducing both aerobic and anaerobic plaque bacteria among other probiotic bacteria, it reduced 3.38 – 2.17 log cfu / gr aerobic bacteria while the same treatment reducing the anaerobic bacteria 2.5- 2.1 log cfu / gr, the probiotic and chlorhexidine groups had less plaque accumulations compared with the control group at the end of 14day (P < 0.001and P < 0.001) respectively . Conclusion : the probiotic mouth rinse was found effective in reducing plague accumulation and gingival inflammation, probiotic mouth rinse obviously has a potential therapeutic value and further study is recommended to determine the efficacy.
