Diagnosis and treatment of physiologic halitosis: a case report

  • 1Department of Preventive Dentistry, Korea University Guro Hospital, Seoul, Korea. youn5801@hanmail.net


We selected a patient with physiological bad breath from among the outpatients with bad breath that have visited the halitosis control clinic in KUMC. We identified the factors that were associated with the development of bad breath and assessed the occurrence of discomfort in the mouth; thereafter, we were able to prescribe a treatment method for the patient. We determined the daily routine of the patient through a questionnaire and a diary of dietary life. From these analyses, we deduced the factors associated with her physiologic halitosis. We combined this information with the results of analysis of her oral and exhaled gas measurements, nasal gas measurements by oral malodor measuring devices, and salivary measurements to develop a treatment method that we prescribed to the patient. We conclude that oral health education, including correction of the patient's mismanaged oral-care methods and routines, could act as an alternative treatment method for patients with physiologic halitosis in Korea.
