Chronic oral malodor, also referred to as halitosis, bad breath, mouth malodor, oral malodor, and fetor oris, is an unpleasant condition that is estimated to affect up to 50% of the population. This common condition is often distressing for patients, causing them social embarrassment and affecting their relationships and self-esteem. Given its prevalence and psychosocial effects, it is no surprise that malodor is one of the chief complaints reported to dental health providers. Effective management depends on identifying the origin of the malodor and instituting the appropriate treatment.

Appropriate for all dental professionals, this basic-level course describes the nature and prevalence of halitosis, reviews the steps for assessing a patient with halitosis, discusses the oral, nonoral, and systemic origins of halitosis, differential diagnosis, and treatment planning. The course also discusses the relationship between oral malodor and oral disease, including gingivitis and periodontitis. Case scenarios highlight the concepts presented and reinforce learning.
