Plain English Summary
Background and study aims
Mouth rinses are considered as an essential mean of oral hygiene, but due to the side effects of its chemical ingredients the search for a natural alternative had begun. Honey is one of these alternatives and has been long known for its antimicrobial properties.
Aims: This study aimed to evaluate the efficacy of Syrian Honey mouth rinse on salivary flora in comparison with Chlorhexidine 0.12% mouth rinse.
Who can participate?
Healthy adults with good oral hygiene.
What does the study involve?
Participants are randomly allocated to use the products, Honey mouth rinse, Chlorhexidine 0.12% mouth rinse, or placebo, in a different order. Participants use each product once for 30 seconds, after seven days they use the next product etc. One minute and 30 minutes after using the product a saliva sample will be collected.
What are the possible benefits and risks of participating?
Possible benefit is finding an alternative for the chemical mouth rinse by using a certain concentration of honey. There are no risks from participating at all, all three groups of treatment used approved materials which causes no harms for patients, groups A commercial chlorhexidine, group B honey mouth rinse, group C distilled water.
Where is the study run from?
Damascus University - Faculty of Dental Medicine, Syria
When is the study starting and how long is it expected to run for?
January 2019 to March 2019

Intra oral flora
The effectiveness of Syrian honey mouth rinse on salivary floral bacteria was investigated at the inhibitory concentration suitable for use as a mouth rinse define by diffusion method on Muller-Hinton agar to reach the suitable concentration which is found to be 50%. The disinfecting effect of this 50% solution was studied in a triple blinded study in comparison with Chlorhexidine 0.12%, and distilled water as control. Each participant used the three solutions once for 30 sec 7 days apart. Then the saliva colony forming unit (CFU) count was measured after rinsing by 1 and 30 min.
Group A: honey mouth rinse 50%.
Group B: chlorhexidine 0.12%
Group C: control (distilled water)
The researcher prepared special cards numbered from (1-40) and each patient took one card randomly from a black box, each card had a letter (A,B OR C). each letter refers to a certain treatment group, nether the researcher, the volunteer or the statistician know what the letter refers to until the end of the data analysis.
Primary outcome measure
The colony forming unit counts (CFU) measured using saliva samples collected from each patient on three different timepoints (before the test, after one minute of the mouth rinse, after 30 minutes of mouth rinse)
Secondary outcome measures
Oral health index collected using oral examination and with UNC15 probe (university of North Carolina). Oral data collected from each patient on three different timepoints (before the test, after one minute of the mouth rinse, after 30 minutes of mouth rinse).
1. Plaque index (PI)
2. Gingival index (GI)
3. Decayed, missing, filled teeth index
