Bad breath tester method is used by professionals generally. Most of the times persons suffering from bad breath are the last ones to be aware of the problem.
One’s own nose filters out and ignores most background odors including our own. Some of the ways we can find out ourselves if we have bad breath is to ask someone close to us.
Another method is to lick the back of our hand, let it dry and smell the result. Home tests which test for the presence of sulfur compounds using a chemical reaction are also available.
Bad Breath Tester Halimeter
A bad breath tester called the Halimeter is used by professionals like dentists and by breath clinics to quantify various degrees of bad breath. These devices came into the market in 1991 and they measure the sulfides in a person’s breath. This device determines the concentration of sulfides which correlates to VSC’s or Volatile Sulfur Compounds in a persons breath.
The Halimeter need not be very accurate as any interference can give inaccurate readings. Certain foods like onion and garlic which remain in the bloodstream for a long time can be misinterpreted by the Halimeter as the readings will be of the temporary presence of hydrogen sulfide in the breath. The Halimeter does not specifically test for VSC’s. The alcohol in certain mouthwashes can also result in inaccurate readings as the Halimeter is sensitive to alcohol. Another device for testing for bad breath is a gas chromatograph. Though less accurate, the Halimeter is a more user friendly, portable device which is more cost effective than a gas chromatograph.
Other Bad Breath Tester Tools
Gas chromatography: This method is used by researchers in many scientific fields for testing and identifying a number of compounds. A gas chromatograph is complex equipment which requires specialized training and handling. Unlike a Halimeter a Gas chromatograph is not portable and the breath measurement process is very time consuming. Gas chromatographs take precise measurements of the concentrations of specific compounds in a person’s breath.
Other ways in which researchers in scientific fields test for bad breath are Organoleptic testing, The BANA test, using gas chromatography and using chemiluminescence.
Organoleptic testing: This method of testing is simply a scientific term for using one’s sense of smell to determine the degree of bad breath. This is not an objective method and vastly left to the judge’s various influencing factors such as health conditions, head position and concentration needed to make an accurate interpretation. The measurement is quantifying in terms of vague gauges of measurement like weak, medium or strong. The judge is also at the risk of getting desensitized to the smells towards the end of the testing.
The BANA test: The bacteria which cause periodontal diseases produce an enzyme that breaks down the compound BANA (benzoyl-D, L-arginine-naphthylamide). When a sample of patient’s saliva is placed with the compound it degrades the compound and changes its color indicating the presence of the odor causing bacteria.
Chemiluminescence testing: This method of testing is more sensitive to the presence of low levels of sulfur compounds compared to the Halimeter. This involves mixing a sample containing sulfur compounds with a mercury compound resulting in fluorescence.
