title: The role of Solobacterium moorei in oral malodour.
abstract: This study aims to analyze the correlation between Solobacterium moorei (S. moorei), both on the tongue and in saliva, and several oral malodour- and clinical parameters. Data from 193 patients visiting a halitosis clinic were used for analysis. A questionnaire assessed their general health, allergies, medication, smoking habits and oral hygiene. Following halitosis parameters were recorded: organoleptic score (OLS) (0-5), total concentration of volatile sulfur compounds (VSC) (Halimeter), individual concentrations of VSC (Oral Chroma), tongue coating (MTCI, WTCI and mWTCI), salivary parameters (flow rate and pH), oral hygiene, tonsil health and periodontal health. In all subjects, microbiological samples were collected from the tongue coating and from the saliva, and a quantitative polymerase chain reaction was performed to detect S. moorei. A significant correlation could be established between S. moorei, from both tongue and saliva, and several breath parameters (OLS, H2S, CH3SH, (CH3)2S and total VSCs), tongue coating indices and periodontal indices (gingivitis, periodontitis and oral hygiene). This study suggests a strong association between the presence of S. moorei and oral malodour (s54747).
