Halitosis (Bad breath) is classified into physiological bad breath and oral or systemic diseased bad breath. When halitosis is caused by oral disease, odor originate in the oral cavity. When halitosis is caused by systemic disease, odor is part of into the expired air. Physiological halitosis and morbid halitosis are collectively called genuine halitosis. Physiological halitosis depends on lifestyle and age. Halitosis which occurs at the time of rising in the morning is the frequent type of physiological halitosis. Halitosis caused by oral disease has been thought to be caused by dental plaque. However, it has been shown recently that the tongue coating (fur) is the cause of halitosis. In the case of periodontal disease, it is important to remove the fur which is located at the root 1/3 of the tongue simultaneously throughout the periodontal treatment. Moreover, bad odors from the oral cavity are caused mainly by volatile sulfur compounds (VSC). Pseudo-halitosis and halitophobia are generally called self-halitosis. However, when it is a self-halitosis, the patient should receive not only dental treatment but also by medical treatment in psychosomatic internal medicine. Most patients with halitophobia were not treated ambitiously because most people with self-halitosis could not judge their condition and feeling by other people, including dentists. eighty percent or more of people will tend to develop self-halitosis. This is important self-halitosis is cased by too much strain in many cases. We must help relax not only the patient's mental state to also make relax not only mentality but also orbicular muscle of mouth. Diagnosis of halitosis is performed by dividing the contents of questions so that the cause of halitosis can be distinguished throuh a questionnaire at first. Next, odor is judged by organic functional inspection, and the amount of gas in the oral cavity or respiratory organ is measured by apparatus. Organic functional inspection is a formal method of judging a bad odor in Japan. It is necessary to be training always for judging the odor of patients and make the inspection capability not decline. Odor measurement by apparatus has the advantage of explanation to the patient. Various gases are also measurable. We need to know which portion of the bad smell substance is measured, and it is necessary to use it for the purpose collectively.
