The OralChromaâ„¢ is a portable gas chromatograph offering lower cost, higher performance, and more user-friendly operations than conventional gas chromatographs by limiting the target gases to three types. It measures the volatile sulfur compounds (VSC) hydrogen sulfide, methyl mercaptan, and dimethyl sulfide-a major causative factor in halitosis-and displays each gas concentration. Measuring each component of VSC not only helps to identify the cause of halitosis, a major symptom of periodontal disease, and to check the efficacy of treatment, but also enables the patient to see the treatment processes and results. The product motivates patients to treat halitosis, eventually resulting in an increased number of patients.
