Oral malodour is considered to be caused mainly by the production of volatile sulfide compounds (VSC) by anaerobic Gram-negative oral bacteria. Previous study showed that these bacteria were susceptible to blue light (wavelengths of 400-500 nm). In the present study, we tested the effect of blue light in the presence of red dyes on malodour production in an experimental oral biofilm. Biofilms were exposed to a plasma-arc light source for 30, 60, and 120 s (i.e. fluences of 41, 82, and 164 J cm(-2), respectively) with the addition of erythrosine, natural red and rose bengal (0...

Oral malodour is a common condition which affects a large proportion of the population, resulting in social, emotional and psychological stress. Certain oral bacteria form a coating called a biofilm on the tongue dorsum and degrade organic compounds releasing volatile sulfur compounds that are malodourous. Current chemical treatments for oral malodour such as mouthwashes containing chlorhexidine or essential oils, are not sufficiently effective at reducing the bacterial load on the tongue. One potential alternative to current chemical treatments for oral malodour is the use of light activated antimicrobial agents (LAAAs), which display no toxicity or antimicrobial activity in the dark, but when exposed to light of a specific wavelength produce reactive oxygen species which induce damage to target cells in a process known as photodynamic inactivation...

The dynamic development of knowledge in the field of probiotics was commenced at the beginning of the 20th century. Since then, many ways of their possible usage in medicine have been established. In accordance with the WHO, probiotics are live microorganisms, which if applied in adequate amounts may benefit the host. Among probiotics, fungi and bacteria are distinguished, and mechanisms of action of these organisms in the oral cavity and gut are parallel. Application in dentistry, in prophylaxis and treatment of oral diseases is still not well known...

This review will discuss the importance of Zinc in the maintenance of oral health. Zinc (Zn) is a trace element of valuable importance. In the oral cavity, it is naturally present at various sites such as dental plaque, dental hard tissues and saliva. It is proven to be effective against common prevalent oral health problems such as dental caries, gingivitis, periodontitis and malodour. It is being used in various oral health care products to control the formation of dental plaque and inhibiting the formation of dental calculus...

INTRODUCTION: In previous studies, toothpastes with high levels of sodium bicarbonate (>50%) have reduced gingival inflammation and oral malodour. This study compared the effects of brushing for 6 weeks with 67% (test group) or 0% (control group) sodium bicarbonate toothpaste on gingival health. METHODS: This was a single-centre, single examiner-blind, randomized, controlled, two-treatment, parallel-group study. Eligible subjects (≥18 years) had ≥20 gradable teeth, mild-to-moderate gingivitis, a positive response to bleeding on brushing and ≥20 bleeding sites...

The role of probiotic bacteria in improving human health has been an attractive subject for researchers since the beginning of the 20(th) century. They have been used to control gastro-intestinal infections, to promote immunity and to prevent various diseases (allergies, urogenital infections, etc.). However, the use of beneficial bacteria in the field of dentistry has only recently gained interest. Investigation of the effects of probiotic bacteria on oral health has become an important research subject. These studies are still in the early stages, however results show that probiotic bacteria are effective against tooth caries, periodontal disease, oral mucosal lesions and oral malodour...

Halitosis is an unpleasant condition that may be the origin of concern not only for a possible health condition but also for frequent psychological alterations which may lead to social and personal isolation. The most frequent sources of halitosis that exist in the oral cavity include bacterial reservoirs such as the dorsum of the tongue, saliva and periodontal pockets. Volatile sulphur compounds (VSCs) are the prominent elements of oral malodour. Genuine halitosis and pseudo-halitosis should be in the treatment realm of dental practitioners...

Halitosis is a common and devastating condition, which may affect up to 1/3 of the population. It can be classified either as genuine halitosis, pseudohalitosis, or halitophobia. Genuine halitosis is more common and usually related to an organic pathology such as periodontitis. Malodour molecules such as sulfur compounds that arise from bacterial interactions generate the basis of oral malodour. Pathologies of the tongue, poor oral hygiene, deep caries, cryptic tonsillary hypertrophia, and postnasal drainage are also associated with halitosis...

Zinc (Zn) reduces the formation of volatile sulphur compounds (VSCs) associated with oral malodour. Although strontium (Sr) is included in some products for reducing dental hypersensitivity, it may also have anti-halitosis properties. This randomized, double-blind, cross-over clinical study compared the anti-VSC effect of brushing with commercial toothpastes and rinses containing Zn and Sr. The volunteers (n = 30) either brushed/rinsed with/without tongue brushing using Zn-containing toothpaste/rinse, Sr-containing toothpaste/rinse, or placebo (control)...

The aim of the review was to critically appraise the various pros and cons of the synthetic and herbal agents used in mouthwashes against halitosis and facilitate users to choose appropriate mouthwashes according to their need. Oral Malodour (OMO) or halitosis is a global epidemic with social and psychological impact. Use of mouthwash has been adopted worldwide to control halitosis within a past few decades. Alcohol and Chlorhexidine are common agents in synthetic mouthwashes, while Tannins and Eugenol are derived traditional herbal extracts...

Halitosis as oral malodour is an unpleasant odour caused by volatile sulfur compounds (VSCs). VSCs are produced primarily by anaerobic bacteria that abundantly produce proteinase as trypsin-like enzyme. General therapies, such as mouthwash and plaque control, do not provide a continuous effect on oral halitosis. Streptococcus thermophilus is a probiotic bacterium that is beneficial for human health. The aim of this study was to evaluate the effect of S. thermophilus on Porphyromonas gingivalis-producing VSCs and to analyze the inhibitory mechanism of halitosis...

Previous studies have shown that these bacteria are susceptible to blue light (400-500 nm wavelength). In the present study, we tested the effect of blue light in the presence of zinc, erythrosine B or both on malodour production in an experimental oral biofilm. Biofilms were exposed to a plasma-arc light source for 30, 60 and 120 s (equal to energy fluxes of 41, 82 and 164 J cm(-2), respectively) with or without the addition of zinc acetate, erythrosine B or both...

OBJECTIVES: The goal of this work is to evaluate the association between organoleptic scores, oral condition and salivary β-galactosidases, to facilitate the differential diagnosis of halitosis in children. METHODS: Fifty systemically healthy children with a primary complaint of oral malodour were included in this cross-sectional study. The organoleptic evaluation was carried out by two judges, evaluating the intensity of malodour of the air exhaled 5 s through the mouth of the patients, at a distance of approximately 10 cm from their noses; the level of salivary β-galactosidases was quantified spectrophotometrically after a chromatic reaction between a salivary sample of each patient and a specific chromatic substrate of the enzyme...
