The Kreapelin test was used as the psychological tool to analyze the relationship between halitosis and psycho-social stress for the comparison of changes in salivation and oral breath. Measurements were made on one woman and six men with a mean age of 34.6 years old. We collected mixed saliva from each for 15 minutes before and after the Kreapelin test. Oral breath was measured just before the Kreapelin test, in the 5 minute rest period during the test and just after the finish.
The scores for oral breath were lowest before the Kreapelin test, medium in the rest period and maximal just after the finish of the test. The amount of mixed saliva in the 15 minute periods was lower after the finish of the Kreapelin test. From these results, it seems possible that psycho-social stress does influence halitosis.
