Bad Breath

Halitosis means an unpleasant odor of the expired air, regardless of the source of this odor. The foul breath originating from the oral cavity itself is termed as oral malodor and it is usually the main contributor of unpleasant breath in an otherwise healthy individual. The most predominant causes of halitosis are gingivitis, periodontitis, and tongue coating. However, several non-oral pathologic conditions have also been related to halitosis, including infection of the upper and lower respiratory tracts, the gastrointestinal tract, and some metabolic diseases involving the kidneys and the liver, which should never be overlooked. Though this complaint of bad breath has existed from time immemorial, it has only recently come to scientific platforms of analysis and is being increasingly recognized as a social stigma in an ever-growing sensitive society. Breath malodor has important socio-economic consequences. Literature reveals almost $1 billion a year is spent in the United States on deodorant-type mouth rinses and mints which provide only short-term masking effects, instead of spending the money on a proper diagnosis and etiologic care to manage bad breath. Sulfur containing volatiles are the main constituent of oral malodor and that their levels correlate with the intensity as determined organoleptically. The treatment of intraoral halitosis consists of scaling/root planing and daily removal of tongue coating, and for extraoral halitosis, treatment of underlying systemic disease by a specialist.

Relevance. Modern data confirm multimicrobial etiology of oral malodor that can significantly compromise effective therapy. Thus, it is relevent to perform comprehensive study of causes of oral malodour, based on microbiological study of composition of mixed microbial biofilms including culturable and non-culturable microbes and evaluation of efficacy of mouth rinses with broad-spectrum antimicrobial agents.Purpose. To study oral microbiota in oral malodor and its correction with antibacterial mouth rinses.Materials and methods. Subjects, involved in the study, were divided into 3 groups, each having 20 people. Controls didn’t use mouth rinses; experimental group used mouth rinse, containing multicidum; in comparison group chlorhxidine containing mouth rinse was used. Orgnoleptic measurement based on 0-5 Rosenberg scale was applied to score intensity of oral malodor. Coating of the root of the tongue was studied by culture-based methods.Results. The research showed that Multicidum® mouth rinse in comprehensive oral malodor treatment affects aerobic bacteria involved in the pathologic process causing bad breath. Positive effect manifested itself organoleptically according to Rosenberg scale in foul breath reduction and in composition changes of microbiota of the root of the tongue. At thus, amount of microorganisms producing smelly volatile compounds decreased and the number of bacteria inhibiting this process increased amid reduction of spore-forming bacteria that contribute to maintenance of stable microbial communities in oral malodor.Conclusion. Gram-positive cocci and Bacillus-Streptococcus, Enterobacter, Staphylococcus, Granulicatella adiacens, Rothia and aerobic spore-forming bacteria from the Bacillus family that are involved in maintaining the functions of resistant bacterial communities-predominated among the bacteria identified in patients with halitosis. There was a statistically significant decrease in the severity of halitosis under the action of a rinse aid, the main active substance of which is Multicidum , and the absence of a statistically significant effect when using a rinse aid based on chlorhexidine.

ABSTRACT Halitosis is a very common condition which may affect up to 30% of the population. In most cases the aetiology of the condition is from local oral causes (oral malodour). Oral malodour is the result of the action of anaerobic bacteria in producing a range of malodorous molecular species including volatile sulphur compounds. Patients with halitosis may seek treatment from dental clinicians for their perceived oral malodour. Physiologic halitosis, oral pathologic halitosis and pseudo-halitosis would be in the treatment realm of dental practitioners. Management of oral malodour is directed at managing and reducing the bacterial load both in periodontitis and in tongue coatings by instituting proper oral hygiene measures, control of tongue flora by brushing or scraping, and possibly the adjunctive use of antiseptic agents. Treatments have also been proposed to neutralise malodorous compounds by chemical agents to mask the presence of the condition. Further evidence is required to demonstrate the long-term efficacy of therapies for this troublesome condition. The purpose of this article is to review the etiology, diagnosis and treatment of oral malodor from a periodontal perspective. The review will be limited to bad breath odors originating within the mouth.
