He helped organize international meetings on the subject of diagnosis and treatment of bad breath, was a founding member of the International Society for Breath Odor Research, lectured internationally, and trained a cadre of international experts on this subject.
Estimated rates of bad breath vary from 6% to 50% of the population. [1] Concern about bad breath is the third most common reason people seek dental care, after tooth decay and gum disease. [2] [3] It is believed to become more common as people age. [1] Bad breath is viewed as a social taboo and those affected may be stigmatized.
It is a colorless gas with a distinctive putrid smell. It is a natural substance found in the blood, brain and feces of animals (including humans), as well as in plant tissues. It also occurs naturally in certain foods, such as some nuts and cheese. It is one of the chemical compounds responsible for bad breath and the smell of flatus.
Mouthwash or breath mints are not particularly effective, since the sulfurous compounds are absorbed into the bloodstream, and exit the body through the lungs and skin. Consuming parsley is a common folk remedy. [6] Studies conducted at Ohio State University have shown that drinking milk can reduce garlic breath.
Tonsil stones may produce no symptoms or they may be associated with bad breath. [1] In fact, many dental professionals argue that tonsil stones are the leading cause of bad breath in their patients. The smell may be that of rotting eggs. [11] Tonsil stones tend to happen most often in people with longterm inflammation in their tonsils. [12]
A Halimeter is an instrument for measurement of the level of volatile sulfur compounds (VSCs) in the mouth.. Halimeter was introduced in the early 1990s as an adjunct method for determining halitosis (bad breath, oral malodor) levels, alongside human assessment of odor levels (the latter is considered the gold standard).
Halitosis appears to be the most common manifestation of ORS, [6] with 75% complaining of bad breath, alone or in combination with other odors. [7] The next most common complaint was sweat (60%). [7] Although all individuals with ORS believe they have an odor, in some cases the individual reports they cannot perceive the odor themselves.
