To determine the influence of oral status on halitosis, the relationship between halitosis and periodontopathic bacteria present in plaque on the tongue and the subgingival sulcus was examined in 62 periodontally healthy adults. Halitosis indicators used were the organoleptic score; gas chromatography results [total volatile sulfur compounds (VSCs) = H(2)S + CH(3)SH + (CH(3))(2)S]; Halimeter values; and the results of three clinical tests, plaque control record (PlCR), plaque index (PlI), and tongue coat status. ⋯ Significant effects on the organoleptic scores, tongue coat status, total VSC, H(2)S and CH(3)SH amounts, and Halimeter values were observed only for T. denticola and F. nucleatum and only in the tongue plaque, not in the subgingival plaque. Thus, therapies developed to inhibit the growth of these bacteria may lead to future treatments of halitosis.
