Our committed dental hygienists work closely with patients on a one-to-one basis to fight gum disease. Since purchasing an Oral Chroma unit in August 2002, our clinic has been collecting and testing samples at a pace of approximately eighty a month. As a halitosis-measuring device, as well as a device for gauging periodontal disease, the Oral Chroma is primarily used to convince patients of the need to address periodontal disease at an early stage and to help measure the efficacy of oral health measures each time they return for a follow-up visit. In particular, with 80% of periodontal disease cases said to involve early-stage treatment procedures, proper communication can be a decisive key to the success or failure of such procedures. While experts consistently indicate in the introductions to oral health-related literature that taking measurements with gas chromatography is ideal, such equipment is expensive to purchase and maintain and requires extensive training to operate, thus accounting for the popularity of various types of alternative measuring devices. Unlike these other products, Oral Chroma relies on gas chromatography for precise measurements (ng/10 ml and ppb) and can be set up to digitally display the results of on-the-spot testing of the oral cavity by the use of animation or graphics. The impact this device has had on patients has been greater than anything we could have previously imagined. It is extremely easy to use since an operator is only required to draw a sample and inject it into the inlet of the Oral Chroma unit. This means that a patient is not required to move to another location and can view an animated graph on the unit’s display. (Display extension codes and distributors are required in our clinic for three units.) Because all that is required to collect a sample is to draw gas, no pain or discomfort is caused to the patient, instructions can be issued in conjunction with the results of other tests for periodontal disease, and hygienists find the device highly effective as an instructive tool. The frequency with which we use Oral Chroma testifies to our overall satisfaction with this invention.


case2 Introducing a breakthrough machine that makes it possible to scientifically analyze halitosis

There are reportedly many people who suffer from halitosis (though not to such a severe degree as to require treatment on an outpatient basis at a university hospital or the intervention of a dentist specializing in halitosis). There are plenty of examples of television commercials espousing the virtues of gum and candy designed to eliminate bad breath, and an impressive array of products for fighting halitosis can be found in convenience stores and pharmacies.

We had been looking for an instrument that could scientifically measure and analyze the concentrations of compounds responsible for causing halitosis with relative ease and allow us to present the results to patients in clearly understandable terms. Unfortunately, the equipment offered by manufacturers was only able to measure the gross volume of the gas believed to be the main culprit behind halitosis and could produce nothing more for the patient than a piece of paper resembling a convenience store receipt on which was printed out the measurement results.

In sharp contrast to conventional equipment, Oral Chroma is capable of measuring the concentrations of three types of gas closely linked to halitosis-hydrogen sulfide, methyl mercaptan, and dimethyl sulfide-and even allows us to present the results using color graphics on a PC. These features are highly effective for determining what causes halitosis in patients and providing them with the information needed to understand and address this problem.

By explaining to patients with poor test results that improvements can be obtained by ensuring a healthier oral environment while pursuing the treatment of cavities and periodontal disease, success can be better achieved with the emergence of a significant motivating factor distinct from the motivating factor of pain avoidance, which will in turn encourage more repeat visits as part of a total dental care regimen.

Few things bring us greater joy than to see the look of happiness on a patient whose measurement results have improved after being treated.

A transformation in the way patients regard dentistry as a means to meeting certain needs is underway. There is no future for us if we fail to provide customers with the services they demand by limiting ourselves to such traditional tasks as drilling, filling, extracting, and inserting teeth. Our professional survival depends on accommodating the health-driven aspirations of patients who want to have cleaner teeth, an enhanced sense of taste, and fresh breath with which to give others a good impression.

I believe that effective measures to deal with halitosis are essential for dental clinics hoping to respond to these health-driven aspirations of patients.


case3 Using Oral Chroma

Satoh Tamotsu Dental Clinic
(Morioka-shi Iwate Japan)

Director Tamotsu Satoh

Oral Chroma is most exceptional for its ability to classify volatile sulfur compounds into three causal components-hydrogen sulfide, methyl mercaptan, and dimethyl sulfide-and present the results to examinees. While the device does not directly treat halitosis, the ability to visually depict these components and explain the science behind bad breath is without doubt a great boon to practicing dentists. Even though gas chromatography is most suitable for analyzing components, most practicing dentists find it impracticable to own and operate such equipment.

If a patient has concerns regarding our counseling methods, then it is possible that he or she may feel uncomfortable about undertaking a componential analysis or deciding to undergo halitosis testing itself. However, our clinic boasts a solid track record when it comes to building motivation. As an example, our adult patients suffering from periodontal disease are even more motivated to learn how to properly brush their teeth if we can gauge the level of methyl mercaptan in their breath and link it to their condition. Fortunately, cases of acute hardship involving halitosis (including the fear that one has bad breath) can be dealt with in conjunction with a diagnostic examination thanks to the introduction of outpatient facilities for halitosis at dental universities and faculties.

I am confident that most clinical dentists will be competently positioned to respond to the various needs of their patients by using Oral Chroma.


case4 Motivation begins with us

When a patient first visits White Essence for the first time, we have him or her fill out a questionnaire.

As it turns out, we found out by this process that 26.7% of respondents would like more detailed information concerning halitosis. Spotting an opportunity, we decided to develop a halitosis diagnostic system to meet the needs of such patients.

However, only after we started to actually engage in halitosis diagnostics did we realize how difficult it was both to precisely identify the source and cause of halitosis in each case and to get the patient to fully understand the substance and implication of the diagnostic results.

Previous devices designed to measure halitosis were only able to measure one type of gas, as a result of which it was difficult to pinpoint the precise source or cause of a patient’s bad breath. In the case of Oral Chroma, three types of gas can be detected, and the results may be graphed and displayed on a computer screen in such a way that it can be easily interpreted. This allows patients to better grasp the significance of this issue during counseling and facilitates the steps that need to be taken thereafter.
