Chios Mastic Mouthwash and Halitosis and Oral Hygiene in Orthodontic Patients

Plain-language summary

Halitosis is the third most common oral condition perceived by the patients as pathologic, after caries and periodontal diseases. Although it is difficult to estimate the prevalence of halitosis in the population due to the different assessment methods, the available descriptive epidemiologic studies estimate that 30-50% of the population experience oral malodor. Pathologic halitosis most commonly (85%) originates from the oral cavity and is a result of bacterial deposits that cover the tongue or are found in the inflamed oral mucosa, under poor-quality restorations, orthodontic mechanisms, carious lesions or mucosal ulcers. Odor usually results from the microbial degradation of organic substrates present in saliva. This interaction generates malodorous volatile sulfur compounds (VSCs), of which the three most common are: hydrogen sulfide (H2S), methyl-mercaptan (CH3SH) and dimethyl sulfide \[(CH3)2S\]. Orthodontic patients with fixed appliances are more prone to halitosis, due to the increased plaque accumulation and the increased amounts of available nutrients for the supragingival and subgingival microbes .
