OBJECTIVES Assess the impact in terms of quality of life 9QoL) of ALIBI (Extract of green tea & Parsley essential oil) in patients suffering from halitosis. METHODS An observational, longitudinal and prospective assessment, carried out in a pharmacy on subjects suffering from halitosis who were seeking an immediate remedy. The questionnaire used was the Halitosis Quality of Life Questionnaire (HQLQ), the only validated questionnaire regarding halitosis. RESULTS A total of 311 subjects suffering from halitosis were included. The average age was 45.07±15.99 years. The sex ratio was 29.90% of men vs 70.10% of women. Also, 71.06% of the subjects exercised a professional activity. Seventy percent claimed they brushed their teeth after each meal; 44.23 of the subjects used accessories (26% inter-dental toothbrushes, 29% dental floss and 11% tongue scrapers). Sixty-six percent stated they became aware of halitosis themselves, 30% from a third party. Halitosis had been present for approximately 5 years; 11% had consulted only their halitosis. The overall HQ22 score was 14.68±7.86, after 7 days of treatment by Extract of green tea & Parsley essential oil, the score was 10.23±8.00. The improvement was statistically significant (p<0.001). The evolution of each of the 4 dimensions (“daily life”, “mental”, “emotional”, “social and work”) also improved. The everyday life score changed from 2.95±2.10 to 1.89±1.92, the Emotional score changed from 2.46±2.10 to 1.81±1.95, the Mental score changed from 4.45±2.75 to 3.22±2.80 and the Social & Work dimension score changed from 4.92±2.50 to 3.54±2.60 CONCLUSIONS Since using Extract of green tea & Parsley essential oil, 90% of subjects suffering from halitosis have experienced an improvement in their everyday lives, 83% feel more at ease in their cultural and social activities. These results confirm the improvement of QoL among subjects suffering from halitosis after 7 days of treatment.
