Use of TheraBreath products in Bad Breath Patients:

(GCF and Halimeter Values, Effects of Oxygenized Saliva)
by: Drs. G. Acikgoz, I. Devrim, M. Aldikacti, A. Kayipmaz, G. Keles – Professors of Periodontology at The Ondokuz Mayis University Dental School, Department of Periodontology – Samsun, Turkey

This independent study was presented abt the 4th International Symposium on Oral Malodor, held at The University of California, Los Angeles (UCLA).

There are several etiological roles which play a role in the ethiopathogenesis of bad breath. However, the major role is the bacterial production of hydrogen sulphide. These anaerobic bacteria live in areas where oxygen cannot reach them, including the back of the throat and tongue, interproximal areas of the teeth, periodontal pockets and enlarged tonsilla. A benefit to those who suffer with bad breath would be the use of an oxygenating agent which would eliminate the hydrogen sulphide and the anaerobic bacteria.

Twenty-five subjects suffering with bad breath were treated with TheraBreath brand stabilized chlorine dioxide mouthwash, toothgel, and spray. Their progress was monitored by using 3 scientifically reproducible methods:

Flame Gas Chromatography, used to measure the production of Volatile Sulphur Compounds in laboratories.

The Interscan Halimeter, which is used by some dentists to monitor the production of sulphides in their dental offices.

Periotron 8000, which measures the concentration of anaerobic bacteria and sulphides in collected saliva.

Results showed the following:

The Flame Gas Chromatography readings of Volatile Sulphur Compounds decreased significantly following use of the products.

A statistically significant decrease in Halimeter readings, showing that the oxygenating effect of TheraBreath reduced volatile sulfur compounds.

Readings on the Periotron 8000 with regards to patients saliva showed that TheraBreath had a beneficial effect.

Notes: This study was translated from Turkish so that it could be presented at the 4th International Symposium on Oral Malodor at the University of California at Los Angeles.

The following independent study was performed over several weeks at the office of Fred Heller DDS, San Francisco, CA on patients who had bad breath and were then instructed on the use of TheraBreath products.

Reduction of Oral Malodour by a Chlorine Dioxide Containing Mouthrinse; Likely mechanisms of Action in Vivo

The change in volatile sulfur compounds (VSC) levels intraorally as recorded by a Halimeter was studied as a potential method to investigate the mode of action and efficacy of a chlorine dioxide (ClO2) mouthwash used as an anti-halitosis agent. The Halimeter was used to monitor the levels of H2S (hydrogen sulfide) every 2 minutes following a 0.1% (w/v) cysteine mouthrinse, which was held in the mouth for one minute prior to expectoration.

The results from an initial study with three participants showed that the VSC response reached a maximum recorded level at either 4 or 6 minutes and returned to around baseline levels after approximately 30 to 40 minutes.

Furthermore, a second cysteine mouthrinse applied within 1 to 2 hours following the first rinse gave a trend towards a larger H2S response, indicating inducibility of VSC production. This experiment involved application of a control rinse (water) on day 1 and a chlorine dioxide rinse (test) on day 2, 75 minutes following a first recorded cysteine-H2S response and one hour prior to a second recorded cysteine-H2S response, on 20 participants.

The results showed that the second cysteine-H2S response was significantly reduced (43% reduction; p< 0.05) following the chlorine dioxide rinse test agent, compared to the water control. These results indicate that the mechanism of action of the chlorine dioxide reduction of VSC production is unlikely to be primarily mediated by oxidation of substrate or VSC product.

Microbiological sampling of the tongue flora following cysteine, water, and chlorine dioxide mouthrinses showed no significant differences in the recovery of aerobic, facultative anaerobic, or strict anaerobic tongue species, suggesting that one of the main mechanisms of action of chlorine dioxide may be irreversible inhibition of the major cysteine to H2S enzyme, cysteine desulfhydrase.

Bad Breath Wake Up Call – Dr. Katz on the CBS Early Show

International Guru Of Good Breath Shares His Secrets

Armed with the Halimeter, Dr. Katz shares secrets to bad breath relief to Early Show anchor Julie Chen.

Bad Breath Relief

Bad breath can be an embarrassing problem for people who often don’t even know they have it. Dentist Dr. Harold Katz shares tips for bad breath relief and prevention with Julie Chen.

Bad breath can be a huge problem for people who have it and often they don’t even know it’s a problem.

Dr. Harold Katz, a dentist, is the founder of California Breath Clinics, and the international guru of good breath. He came to The Early Show to tell people how they can keep their mouths smelling good.

Katz said that bad breath isn’t really caused by what people eat, but by sulfur compounds.

“Chronic bad breath has to due with bacteria that live in the back of your throat with sulfur, different chemicals. Can you imagine what they smell like? And they’re produced by bacteria,” Katz told The Early Show co-anchor Julie Chen. “The problem is people used to think if I use a strong-tasting mouthwash I can cover it up.”

Katz used a hali-meter to test the compounds in the mouth. Anything above 120 means the person has bad breath. He blew into it and had had a 73, which means he has fresh breath. The hali-meter goes all the way up to 2,000.

The problem is that many people do not know they have a breath problem and few have hali-meters to show them. Katz said a good way to tell is to lick the back of you hand and let it dry for a couple seconds and smell it.

Katz said that alcohol, detergent and toothpaste dry out the mouth which adds to bad breath. Even sugar in breath mints feed bacteria to make bad breath worse. The best way to fight bad breath, Katz said, is to oxygenate the mouth.

“These are available in drugstores, discounted stores, supermarkets and online stores,” he said gesturing to some products he brought on to the show. “Oxygenating compounds. It’s the oxygen that stops the bad breath. Very important, you need to drink plenty of water to make sure you have plenty of saliva, nature’s way of keeping your breath fresh. You need to eat juicy fruits such as apples, celery. Dairy could lead to bad breath, sodas and sugar. And there’s probiotic treatments that help with bad breath.”
