“…In studies that have examined intraday variations in physiologic halitosis, the highest levels of halitosis were observed before breakfast, followed by the levels before lunch and before dinner. 12,13 In the present study, halitosis was measured from 2 h after lunch until dinner, a period during which the degree of halitosis is quite high. We fi rst examined the correlations between the organoleptic score and the various intraoral tests, the amounts of VSC measured by gas chromatography, and the portable sulfi de monitoring results.…”

“…11 Meanwhile, several reports have described the presence of halitosis even without any particular oral or systemic disease, such as upon wakening in the morning, or associated with an empty stomach or being tired. 12,13 These cases have been defi ned as physiologic halitosis by the Fourth International Society for Breath Odor Research. 14 More specifi cally, physiologic halitosis was defi ned as halitosis that clearly exceeds a socially acceptable level when neither a specifi c disease nor a pathologic condition that could cause halitosis has been found.…”

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 correlations with organoleptic scores was observed for PlCR, PlI, tongue coat status, VSC amounts, and Halimeter values, indicating that halitosis in periodontally healthy subjects tended to originate from tongue plaque deposits. Polymerase chain reaction analysis was used to detect six periodontopathic bacteria (Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia, Tannerella forsythensis, and Treponema denticola) from the tongue and subgingival plaque. 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.

“…3,4 Physiologic halitosis is commonly experienced as morning breath attributed to accumulation of tongue coat overnight in the interlude between oral hygiene routine and stagnation of saliva. 5 Proteolytic bacteria found within the accumulated tongue coat produce VSC by protein degradation contributing to characteristic odors of physiologic halitosis. The substrates for VSC are mainly sulfur-containing amino acids that are found in saliva, gingival crevicular fluid, and acquired tongue coats.…”

Comparative Evaluation of Tongue Coat Inhibitory Effect of 1% Stabilized Chlorine Dioxide Mouthrinse with that of 0.2% Chlorhexidine Gluconate Mouthrinse in the Treatment of Halitosis using N-benzoyl-DL-arginine-2-naphthylamide Assay: A Randomized Crossover Study

Aim: To evaluate the efficacy of 1% Stabilized Chlorine dioxide (ClO 2) mouthrinse as compared with 0.2% Chlorhexidine gluconate (CHX) mouthrinse on tongue coat assessed by N-benzoyl-DL-arginine-2-naphthylamide (BANA) assay in the treatment of halitosis. Materials and methods: Twenty systemically healthy subjects with self-reported halitosis were enrolled in the study as per the inclusion criteria. The participants were assigned to use either aqueous 1% stabilized ClO 2 mouthrinse (Group I) or aqueous 0.2% CHX mouthrinse (Group II). The study was conducted in two phases of 15 days duration each with an intervening washout period of 7 days. Subjects were assessed at baseline and 15 days in each phase for oral hygiene using Plaque index (PI) and Winkel tongue coating index (WTCI). Volatile sulfur compound (VSC) in exhaled breath was measured using portable sulfide monitor. On the 15th day, tongue coating samples were assessed for both Groups using chairside BANA assay. Results: Both Groups I and II demonstrated significant reduction in PI scores at 15 days as compared with baseline. However, reduction in PI score was found to be statistically significant in favor of Group I as compared with Group II after 15 days (p-value: 0.001). Reduction in WTCI scores was statistically nonsignificant for both Groups I and II at 15 days (p-value: 0.094). Qualitative VSC scores by portable sulfide monitor on assessment of exhaled breath was statistically nonsignificant for both Groups I and II at 15 days (p-value: 0.131). The BANA scores for tongue coat samples from both Groups were comparable at 15 days with no statistical significance (p-value: 0.503). Conclusion: The observation from present study settings would lead to infer that dental plaque inhibition, tongue coat inhibition, and VSC production are comparable for both the Groups in the treatment of physio logical halitosis.
