Assessment of Probiotic Yogurt on Oral Malodor by Organoleptic method

Probiotics could have benefits on oral health, partially through modifying oral cavity microflora. The purpose of this study was to investigate the effect of a commercial probiotic yogurt consumption on oral halitosis. This clinical trial was conducted on 44 volunteers suffering from halitosis with oral cavity origin. The subjects were given 200 ml probiotic yogurt daily for a period of two weeks. One examiner evaluated subjects’ mouth odor at baseline and after two weeks using organoleptic assessment (5 point scale: 0= no, 1= brief, 2= medium, 3=severe, and 4= very severe) at 10 and 50 cm distances. Data were analyzed by SPSS software using Wilcoxon test (&alpha=0.05). Baseline mean organoleptic scores (10 and 50 cm) were 2.63±1.12 and 1.95±1.23, which decreased to 1.45±1.10 and 0.95±0.93 at the end of study (P< 0.001). consumption of probiotic products could be considered as an effective strategy for improvement of halitosis with mouth origin.
