Lavandula angustifolia Essential Oil Inhibits the Ability of Fusobacterium nucleatum to Produce Volatile Sulfide Compounds, a Key Components in Oral Malodor. Molecules 2024; 29:2982. [PMID: 38998934 PMCID: PMC11243465 DOI: 10.3390/molecules29132982] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2024] [Revised: 06/16/2024] [Accepted: 06/16/2024] [Indexed: 07/14/2024] Open
Abstract
Oral malodor still constitutes a major challenge worldwide. A strong effort is invested in eliminating volatile sulfur compound-producing oral bacteria through organic natural products such as essential oils. Fusobacterium nucleatum is a known volatile sulfur compound-producing bacteria that inspires oral malodor. The aim of the present study was to test the effect of lavender essential oil on the bacterium's ability to produce volatile sulfide compounds, the principal components of oral malodor. Lavender (Lavandula angustifolia) essential oil was extracted by hydrodistillation and analyzed using GC-MS. The minimal inhibitory concentration (MIC) of lavender essential oil on Fusobacterium nucleatum was determined in a previous trial. Fusobacterium nucleatum was incubated anaerobically in the presence of sub-MIC, MIC, and above MIC concentrations of lavender essential oil, as well as saline and chlorhexidine as negative and positive controls, respectively. Following incubation, volatile sulfur compound levels were measured using GC (Oralchroma), and bacterial cell membrane damage was studied using fluorescence microscopy. Chemical analysis of lavender essential oil yielded five main components, with camphor being the most abundant, accounting for nearly one-third of the total lavender essential oil volume. The MIC (4 µL/mL) of lavender essential oil reduced volatile sulfur compound secretion at a statistically significant level compared to the control (saline). Furthermore, the level of volatile sulfur compound production attributed to 1 MIC of lavender essential oil was in the range of the positive control chlorhexidine with no significant difference. When examining bacterial membrane damage, 2 MIC of lavender essential oil (i.e., 8 µL/mL) demonstrated the same, showing antibacterial membrane damage values comparative to chlorhexidine. Since lavender essential oil was found to be highly effective in hindering volatile sulfur compound production by Fusobacterium nucleatum through the induction of bacterial cell membrane damage, the results suggest that lavender essential oil may be a suitable alternative to conventional chemical-based anti-malodor agents.

[PMID: 38888002 DOI: 10.1111/jre.13315] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 05/27/2024] [Accepted: 06/03/2024] [Indexed: 06/20/2024]
Abstract
AIM To explore the association between periodontitis and olfactory disorders. METHODS Clinical data were collected from 198 individuals between the ages of 18 and 60 years living in Denmark. The exposure was periodontitis, and the outcome was olfactory function (Threshold, Discrimination, Identification - TDI score), both measured clinically. Covariates included sex, age, education level, income, usage of nasal spray, tongue coating, halitosis, xerostomia, smoking, and history of COVID-19. Structural equation modeling was used to estimate the association between periodontitis and olfactory function. Periodontitis was defined using the AAP/EFP classification and dichotomized into "no" (healthy subjects) and "yes" (Stages I, II, and III). Olfactory function was treated as a one-factor latent variable, including the different olfactory scores. In addition, extra models were performed considering each olfactory component as a separate outcome and the TDI Global Score. RESULTS The results showed that periodontitis was associated with a lower olfactory function [standardized coefficient (SC) -0.264, 95% CI -0.401, -0.118]. Additionally, periodontitis was also associated with a lower olfactory Threshold (odorant concentration required for detection) (SC -0.207, 95% CI -0.325, -0.089), Discrimination (ability to discriminate between odorants) (SC -0.149, 95% CI -0.270, -0.027), Identification (ability to identify odorants) scores (SC -0.161, 95% CI -0.277, -0.045), and TDI Global Score (SC -0.234, 95% CI -0.370, -0.099). CONCLUSIONS This study suggests that periodontitis is associated with olfactory impairment.

Abstract
OBJECTIVES The purpose of this systemic review and meta-analysis was to explore the association between halitosis and periodontitis in observational studies. MATERIALS AND METHODS A systematic search covered PubMed, Web of Science, Embase, Scopus, and Cochrane Library until August 18, 2023. Nine observational studies (585 cases, 1591 controls) were analyzed using Stata 17, with odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup analyses considered halitosis assessment methods. RESULTS The review found a positive association between halitosis and periodontitis. Significant differences were observed with organoleptic test (OR = 4.05, 95% CI: 1.76, 9.30, p < 0.01) and volatile sulfur compound readings (OR = 4.52, 95% CI: 1.89, 10.83, p < 0.01). CONCLUSIONS A positive association was observed between halitosis and periodontitis, supported by significant differences in both organoleptic and volatile sulfur compound readings. However, conclusive findings are limited by statistical heterogeneity, emphasizing the need for additional research. CLINICAL RELEVANCE Understanding the halitosis and periodontitis association is clinically significant, informing potential interventions for improved oral health. Further research is vital to refine understanding and guide effective clinical strategies, acknowledging the limitations in current findings.

Abstract
BACKGROUND Intra-oral halitosis (IOH) is bad breath produced locally by the mouth in addition to systemic diseases and is one of the main causes of interpersonal communication and psychological disorders in modern society. However, current treatment modalities still only alleviate IOH and do not eradicate it. Therefore, based on the differential performance of oral microecology in IOH patients, we propose a microbiota transplantation treatment aimed at restoring oral microecological balance and analyze its feasibility by oral flora colonization test in Wistar rats. OBJECTIVE Saliva flora samples were collected from IOH patients and healthy subjects to analyze the feasibility of oral microbiota transplantation (OMT) for the treatment of IOH by the Wistar rat oral flora colonization test. METHODS Seven patients with IOH who visited the First Affiliated Hospital of Xinjiang Medical University from June 2017 to June 2022 with the main complaint of halitosis and three healthy subjects were randomly selected. A Halimeter portable breath detector was used to record breath values and collect saliva flora samples. Sixteen SPF-grade male Wistar rats were housed in the Animal Experiment Center of Xinjiang Medical University and randomly divided into an experimental group (Group E) and a control group (Group C) for the oral flora colonization test. Species composition and associated metabolic analysis of oral flora during the Wistar rat test using 16SrRNA sequencing technology and PICRUSt metabolic analysis. Also, the changes in the breath values of the rats were recorded during the test. RESULTS The proportion of Porphyromonas, Fusobacterium, Leptotrichia, and Peptostreptococcus was significantly higher in group E compared to group C after colonization of salivary flora of IOH patients (all P < 0.05), and the abundance with Gemella was zero before colonization, while no colonization was seen in group C after colonization compared to baseline. PICRUSt metabolic analysis also showed significantly enhanced IOH-related metabolic pathways after colonization in group E (all P < 0.05), as well as significantly higher breath values compared to baseline and group C (all P < 0.0001). After colonization by salivary flora from healthy subjects, group E rats showed a decrease in the abundance of associated odor-causing bacteria colonization, a reduction in associated metabolism, and a significant decrease in breath values. In contrast, group C also showed differential changes in flora structure and breath values compared to baseline after salivary flora colonization of IOH patients. CONCLUSIONS OMT for IOH is a promising green treatment option, but the influence of environmental factors and individual differences still cannot be ignored.

Abstract
Background As infrequent social interaction is a potential risk of dementia, oral malodor may increase the risk of dementia, including Alzheimer's disease. Objective This study investigated the association between malodor and dementia. Methods We used the Japan Public Health Center-based Prospective Study data obtained at Yokote City. A total of 1,493 individuals aged 56 to 75 years underwent a dental examination and self-reported survey from May 2005 to January 2006. Follow-up for the onset of dementia was conducted using long-term care insurance data from 2006 to 2016. Hazard ratios of oral malodor on dementia were estimated by the Cox proportional hazards model. The inverse probability-weighted Cox model was used as a sensitivity analysis. Results The study comprised 1493 participants (53.6% women) with a mean age of 65.6 (SD = 5.8) years old; at the end of the follow-up, 6.4% (n = 96) developed dementia, and the percentage was 20.7 in severe malodor group. Throughout 15274.133 person-years of follow-up, the average incidence rate for the onset of dementia per 1000 person-years was 6.29. The highest incidence rate was seen in participants with severe malodor (22.4 per 1000 person-years). After adjusting for confounders, compared to those with no malodor, there was a 3.8 (95% confidence interval: 1.5 to 9.4) times greater hazard of developing dementia in participants with severe malodor. The inverse probability weighted Cox model confirmed the same trend with an adjusted marginal hazard ratio of 4.4 (1.2 to 16.4). CONCLUSIONS A significant association between oral malodor and the onset of dementia exists.

Abstract
Halitosis, commonly known as oral malodor, is a multifactorial health concern that significantly impacts the psychological and social well-being of individuals. It is the third most frequent reason for individuals to seek dental treatment, after dental caries and periodontal diseases. For an in-depth exploration of the topic of halitosis, an extensive literature review was conducted. The review focused on articles published in peer-reviewed journals and only those written in the English language were considered. The search for relevant literature began by employing subject headings such as 'halitosis, oral malodor, volatile sulfur compounds, artificial intelligence, and olfaction' in databases such as PubMed/Medline, Scopus, Google Scholar, Web of Science, and EMBASE. Additionally, a thorough hand search of references was conducted to ensure the comprehensiveness of the review. After amalgamating the search outcomes, a comprehensive analysis revealed the existence of precisely 134 full-text articles that bore relevance to the study. Abstracts and editorial letters were excluded from this study, and almost 50% of the full-text articles were deemed immaterial to dental practice. Out of the remaining articles, precisely 54 full-text articles were employed in this review. As primary healthcare providers, dentists are responsible for diagnosing and treating oral issues that may contribute to the development of halitosis. To effectively manage this condition, dentists must educate their patients about the underlying causes of halitosis, as well as proper oral hygiene practices such as tongue cleaning, flossing, and selecting appropriate mouthwash and toothpaste. This narrative review summarises all possible AI olfaction in halitosis.

Abstract
The major oral odor compound methyl mercaptan (CH3SH) is strongly associated with halitosis and periodontitis. CH3SH production stems from the metabolism of polymicrobial communities in periodontal pockets and on the tongue dorsum. However, understanding of CH3SH-producing oral bacteria and their interactions is limited. This study aimed to investigate CH3SH production by major oral bacteria and the impact of interspecies interactions on its generation. Using a newly constructed large-volume anaerobic noncontact coculture system, Fusobacterium nucleatum was found to be a potent producer of CH3SH, with that production stimulated by metabolic interactions with Streptococcus gordonii, an early dental plaque colonizer. Furthermore, analysis of extracellular amino acids using an S. gordonii arginine-ornithine antiporter (ArcD) mutant demonstrated that ornithine excreted from S. gordonii is a key contributor to increased CH3SH production by F. nucleatum. Further study with 13C, 15N-methionine, as well as gene expression analysis, revealed that ornithine secreted by S. gordonii increased the demand for methionine through accelerated polyamine synthesis by F. nucleatum, leading to elevated methionine pathway activity and CH3SH production. Collectively, these findings suggest that interaction between S. gordonii and F. nucleatum plays a key role in CH3SH production, providing a new insight into the mechanism of CH3SH generation in oral microbial communities. A better understanding of the underlying interactions among oral bacteria involved in CH3SH generation can lead to the development of more appropriate prophylactic approaches to treat halitosis and periodontitis. An intervention approach like selectively disrupting this interspecies network could also offer a powerful therapeutic strategy.IMPORTANCEHalitosis can have a significant impact on the social life of affected individuals. Among oral odor compounds, CH3SH has a low olfactory threshold and halitosis is a result of its production. Recently, there has been a growing interest in the collective properties of oral polymicrobial communities, regarded as important for the development of oral diseases, which are shaped by physical and metabolic interactions among community participants. However, it has yet to be investigated whether interspecies interactions have an impact on the production of volatile compounds, leading to the development of halitosis. The present findings provide mechanistic insights indicating that ornithine, a metabolite excreted by Streptococcus gordonii, promotes polyamine synthesis by Fusobacterium nucleatum, resulting in a compensatory increase in demand for methionine, which results in elevated methionine pathway activity and CH3SH production. Elucidation of the mechanisms related to CH3SH production is expected to lead to the development of new strategies for managing halitosis.

Abstract
BACKGROUND/OBJECTIVES The aim of this trial was to investigate the effect of mastic mouthwash on halitosis using as a proxy the levels of the Volatile Sulfur Compounds (VSCs), and the effect on plaque and gingival indices in adolescents undergoing orthodontic treatment with fixed conventional labial appliances. SUBJECTS/METHODS The study was a double-blinded, placebo-controlled, parallel-group, randomized clinical trial. Thirty patients with fixed orthodontic appliances were randomly allocated at a 1:1 ratio, to either the mastic-mouthwash or the placebo-mouthwash group. Eligibility criteria included ages between 13 and 18, active orthodontic treatment with fixed appliances, good general health, and total initial VSCs levels above 150 ppb. The primary outcome was the objective hydrogen sulfide (H2S) level, measured with the Oral ChromaTM device. The secondary outcomes were (1.) the methyl-mercaptan (CH3SH) and (2.) dimethyl sulfide [(CH3)2S] levels, measured with the same device, (3.) the subjective perception of the own malodour via questionnaires, and (4.) the oral hygiene assessed with the use of the Modified Silness and Löe Plaque Index (PI-M) and the Silness and Löe Gingival Index (GI) at baseline (T0) and after 2 weeks (T1). Stratified randomization by gender was used, and allocation was concealed with opaque numbered sealed envelopes. RESULTS H2S level dropped from 221.00 ppb (T0) to 125.00 ppb (T1), and the difference between treatment groups was statistically significant in favour of the mastic group (coef: 72.34, 95% CI: 8.48, 136.27, P = 0.03). The levels of the other VSCs, the subjective measurements of oral malodour, and the oral hygiene indices did not differ between treatment arms. LIMITATIONS The objective organoleptic assessment by a calibrated examiner was not performed. CONCLUSIONS/IMPLICATIONS Mastic mouthwashes could be an alternative treatment for adolescent patients suffering from halitosis during orthodontic treatment with fixed appliances. REGISTRATION The trial was registered at ClinicalTrials.gov (identifier: NCT05647369).

Abstract
Halitosis is defined as the presence of an unpleasant odor in exhaled air, regardless of its cause. In most patients with halitosis, the condition causes embarrassment and interferes with social interactions and daily life. Furthermore, bad breath can be a sign of an underlying disease. Understanding the factors and causes that lead to halitosis and its manifestations could facilitate proper management of this condition. To properly diagnose and treat patients, healthcare professionals, including primary care physicians and dental professionals, must be familiar with the etiology and appropriate management of the disease. Consequently, this review aims to provide practitioners with up-to-date information on the etiological factors of halitosis to facilitate the establishment of preventive measures and provide accurate diagnosis and management.

Abstract
Background Oral malodor is a major periodontal complaint, but the best method for assessing the halitosis grade is still undefined. The primary objective of the study was to detect the halitosis grade in the exhaled breath using the three distinct techniques and to compare the readings with different clinical indices to find out the best method of halitosis grading. Materials and Methods A total of 90 patients with chronic periodontitis having oral malodor were included in the study. The subjective assessment of the exhaled breath (halitosis grading) was done by three different methods; using a handheld portable Tanita FitScan sulfide monitor, by Halitox toxin assay, and by organoleptic (Sniff test) method. The findings were then compared with the clinical parameters of poor oral hygiene like plaque index (PI), gingival index (GI), gingival bleeding index (BI), and pocket depth (PD) to detect the best method of halitosis grading. Results The mean age of the patients included was 38.23 ± 8.83 (mean ± standard deviation) years. The median value of halitosis grading as obtained by Tanita FitScan was 3.0 (95% confidence interval as 2 and 4) which was then compared with clinical indices (PI, GI, BI, and PD) and the results were statistically significant (P < 0.05), whereas the other two techniques of halitosis grading gave insignificant results. Conclusion The results confirmed that the halitosis grading done using Tanita FitScan sulfide monitor is more appropriate with respect to clinical indices when compared with the other two techniques.

Abstract
Background Oral health is closely related to general health awareness and good oral hygiene practices, which makes it an important aspect of general health and well-being. The current study assessed the knowledge, attitudes, and practices of oral hygiene among secondary school students in Al-Qunfudah district, Saudi Arabia. Methods A convenient sample of 383 male and female secondary school students in the Al-Qunfudah district, Saudi Arabia, was included in this descriptive cross-sectional study. The research data were collected from the study sample through a self-administered online survey via WhatsApp and Telegram electronic applications. Finally, the collected data were coded and analyzed through the Statistical Package for the Social Sciences (SPSS) version 25.0 (SPSS Inc., Chicago, IL) and expressed in frequencies, percentages, mean, and standard deviation. The chi-squared and Fisher's exact tests were applied to assess the relationship between the participants' knowledge and practice scores of oral hygiene and their demographic characteristics. A P-value of less than 0.05 was regarded as significant. Results In this study, female students represented 70% of the sample, and most of them were Saudi (97.0%). Many of them identified the great impact of oral hygiene on overall health (89.2%), and more than two-thirds indicated that brushing their teeth regularly would prevent oral problems (89.2%). Nearly two-thirds of them perceived that dental problems would affect their school attendance; however, 59.1% ignored the important role of schools in maintaining students' oral hygiene. The poor practice of dental care was observed among students, as 47.5% brush their teeth twice daily and a third replace their brushes every three months. Despite the fact that the majority of the study population had adequate knowledge (44.4%) and a positive attitude (78.6%) toward oral hygiene, only 39.9% could effectively apply it. The knowledge of oral hygiene was significantly better among females (P = 0.005), older students (P = 0.001), those at a higher academic level (P = 0.016), and students from Al-Qunfudah city (P = 0.007). Furthermore, older pupils, those with a higher academic level, and those from Al-Qunfudah city performed better in terms of dental hygiene than their peers (P-value was 0.001 for each). Conclusion Secondary school students generally have adequate awareness levels and positive attitudes toward oral hygiene, but they practice it with remarkably little consistency. Schools should emphasize their crucial roles in enhancing oral health among their students of different education levels through their curriculum and frequent monitoring of students. Persuasive and realistic oral health education initiatives are recommended for schoolchildren and their family members or caregivers, with a particular emphasis on males, younger children, and those living in rural areas.

Abstract
This study aimed to verify and to validate the correlation between, and validate the assessment of, bacterial activity and the distribution of tongue coating, by analyzing quantitative light-induced fluorescence (QLF) images for the diagnosis of oral malodor. Oral malodor was measured using the Twin Breasor II, and bacterial activity and the distribution of tongue coating were investigated using QLF images. Bacterial activity and the distribution of tongue coating were quantitatively analyzed by dividing the tongue into six areas using the TB01 1.05 software. ROC curves were generated using MedCalc® software to validate the diagnosis of oral malodor, the testing of bacterial activity, and the distribution of tongue coating. Bacterial activity and the distribution of tongue coating showed a very strong association with each other (r = 0.937, p < 0.01), and were significantly higher in the oral malodor group (p < 0.05). The distribution of tongue coating was highly correlated with H2S (r = 0.223, p < 0.01) but not associated with CH3SH. Sensitivity, specificity, and the area under the curve confirmed the high accuracy of this method in assessing bacterial activity and the distribution of tongue coating in the diagnosis of oral malodor. Since QLF images provide significant accuracy during quantitative analysis in the identification of bacterial activity and the distribution of tongue coating, systematic management of tongue coating and reduced oral malodor can be achieved by actively using QLF images and oral malodor measurement.

Abstract
OBJECTIVES We aimed to conduct a systematic review on published data in order to investigate the efficacy of mouthwash products containing chlorine dioxide in halitosis. STUDY DESIGN Systematic review and meta-analysis. METHODS Our search was conducted on 14th October 2021. We searched the following electronic databases: MEDLINE, Embase, Scopus, Web of Science, and CENTRAL. We analysed data on adults with halitosis, included only randomised controlled trials and excluded in vitro and animal studies. The interventional groups used chlorine dioxide, and the comparator groups used a placebo or other mouthwash. Our primary outcomes were changes in organoleptic test scores (OLS) and Volatile Sulfur Compound (VSC) levels from baseline to the last available follow-up. RESULTS We found 325 articles in databases. After the selection process, ten articles were eligible for qualitative synthesis, and 7 RCTs with 234 patients were involved in the meta-analysis. Our findings showed a significant improvement in the parameters of the chlorine dioxide group compared to the placebo group in OLS one-day data (mean difference (MD): -0.82; 95% confidence intervals (95% CIs): [-1.04 --0.6]; heterogeneity: I2 = 0%, p = 0.67); and one-week OLS data (MD: -0.24; 95% CIs: [-0.41 --0.07]; I2 = 0%, p = 0.52); and also changes in H2S one-day data (standardised mean difference (SMD): -1.81; 95% CIs: [-2.52 --1.10]); I2 = 73.4%, p = 0.02). CONCLUSION Our data indicate that chlorine dioxide mouthwash may be a good supportive therapy in oral halitosis without known side effects.

Abstract
Abstract
The different types of self-reported halitosis complaints include those where one feels that one’s breath smells bad, where one feels that one has bad breath because of the attitudes of others, and where others have pointed out the presence of bad breath. The results of previous studies comparing the objective and subjectives measures of halitosis are inconsistent, and few studies have used gas chromatography (GC) to measure halitosis in a large sample. This study aimed to examine the objectively measured halitosis levels based on the reasons individuals are concerned about halitosis. We included 2063 patients who visited the halitosis clinic at a university dental hospital. Halitosis was assessed using GC, self-administered questionnaires, and oral examinations. Levels of volatile sulphur compounds (VSCs; H2S, CH3SH, and (CH3)2S) were set as objective measures of halitosis. Patients were grouped based on their answers to ‘What made you concerned about bad breath?’ into groups: ‘self-perceived,’ ‘attitudes of others,’ ‘told by others,’ and other reasons. Univariate and multivariable linear regression analyses were performed to examine factors associated with VSCs and objective halitosis levels. Age, sex, oral health status, smoking, drinking, and breakfast habits were used as confounders. Patients who answered ‘told by others’ (n = 691, 33.5%) showed the highest VSCs. Individuals whose halitosis was pointed out by others had higher objectively measured halitosis levels, while those concerned about the attitudes of others or perceived their own halitosis had lower objectively measured halitosis levels. These results suggest that the objective level of halitosis can differ on the basis of the reason underlying an individual’s concern about their bad breath. Categorizing halitosis complaints and comparing them with objective halitosis levels may help reduce the anxiety of those who are concerned about halitosis and confirm the need for intervention for those with objective halitosis.

Abstract
Culture-independent nucleic acid technologies have been extensively applied to the analysis of oral bacterial communities associated with healthy and diseased conditions. These methods have confirmed and substantially expanded the findings from culture studies to reveal the oral microbial inhabitants and candidate pathogens associated with the major oral diseases. Over 1000 bacterial distinct species-level taxa have been identified in the oral cavity and studies using next-generation DNA sequencing approaches indicate that the breadth of bacterial diversity is even much larger. Nucleic acid technologies have also been helpful in profiling bacterial communities and identifying disease-related patterns. This chapter provides an overview of the diversity and taxonomy of oral bacteria associated with health and disease.

Abstract
BACKGROUND Halitosis is defined as a foul odour emitted from the oral cavity. Many interventions have been used to control halitosis from mouthwashes to chewing gums. Probiotics have been reported as an alternative method to alleviate halitosis. OBJECTIVE The present study aimed to investigate the effect of probiotics on halitosis from a time perspective. DESIGN AND METHODS This is a meta-analysis study performed in indexed databases up to February 2021. Randomised controlled trials that compared the effects of probiotics and placebo on primary outcomes (organoleptic (OLP) scores and volatile sulfur compound (VSC) levels) and secondary outcomes (tongue coating scores (TCS) and plaque index (PI)) were included. Data extraction and quality assessment were conducted independently by two reviewers. Publication bias and leave-one-out analyses were performed. RESULTS The standardised mean difference (SMD) and 95% CI were calculated to synthesise data. The data were subgrouped and analysed in the short term (≤4 weeks) and long term (>4 weeks) based on the follow-up time. Seven articles were included in this meta-analysis. The primary outcomes, OLP scores (SMD=-0.58; 95% CI -0.87 to -0.30, p<0.0001) and VSC levels (SMD=-0.26; 95% CI -0.51 to -0.01, p=0.04), both decreased significantly in the probiotics group compared with the placebo group in the short term. However, a significant reduction was observed only in OLP scores (SMD=-0.45; 95% CI -0.85 to -0.04, p=0.03) in the long term. No significant differences were observed in secondary outcomes. There was no evidence of publication bias. The leave-one-out analysis confirmed that the pooled estimate was stable. CONCLUSIONS According to the results of this work, it seems that probiotics (eg, Lactobacillus salivarius, Lactobacillus reuteri, Streptococcus salivarius and Weissella cibaria) may relieve halitosis in the short term (≤4 weeks). The results of the biased assessment, limited data and heterogeneity of the clinical trials included might reduce the reliability of the conclusions.

Abstract
Halitosis, or bad breath, is an oral health problem characterized by an unpleasant malodor emanating from the oral cavity. This condition can have different origins and causes a negative burden in social interactions, communication and quality of life, and can in uncommon cases be indicative of underlying non-oral non-communicable diseases. Most cases of halitosis are due to inadequate oral hygiene, periodontitis and tongue coating, yet the remaining proportion of cases are due to ear-nose-throat-associated (10%) or gastrointestinal/endocrine (5%) disorders. For this reason, the diagnosis, treatment and clinical management of halitosis often require a multidisciplinary team approach. This comprehensive review revisits the etiology of halitosis as well as standard and novel treatment that may contribute to higher clinical success.

Abstract
We have measured the composition of volatile organic compounds (VOCs) in the morning breath of 30 healthy individuals before and after tooth brushing. The concentrations of VOCs in the breath samples were measured with proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) and further identification was performed with a combination of solid phase microextraction (SPME) and offline gas chromatography-mass spectrometry (GC-MS). We hypothesize that compounds, whose concentrations significantly decreased in the breath after tooth brushing are largely of microbial origin. In this study, we found 35 such VOCs. Out of these, 33 have been previously connected to different oral niches, such as salivary and subgingival bacteria. We also compared the concentrations of the 35 VOCs found in increased amounts in the morning breath to their respective odor thresholds to evaluate their ability to cause odor. Compounds that could contribute to the breath odor include many volatile sulfur compounds, such as methanethiol, hydrogen sulfide, dimethyl sulfide, and 2-methyl-1-propanethiol, but also other VOCs, such as acetic acid, butyric acid, valeric acid, acetaldehyde, octanal, phenol, indole, ammonia, isoprene, and methyl methacrylate.

Abstract
Halitosis is an unpleasant odor discharged through the oral cavity with a prevalence as high as 30%-50% of the general population. Conventional diagnostic methods have been focused on mouth air analysis measuring the amount of sulfur compounds which does not directly reflect the cause of halitosis. Also, the possible role of halitosis as an indicator of general health status has been steadily suggested and inflammation has been constantly associated with aversive body odor. Therefore, this study aimed to search for inter-relationships between hematologic indicators, clinical characteristics, and halitosis measurement that can predict the presence of pathologic halitosis and its intensity. Furthermore, the tentative relationship between halitosis and the presence of systemic inflammation was investigated. A total of 125 patients were divided into 103 patients in the genuine halitosis group (value ⩾80 ppb) and 22 patients in the pseudo halitosis group (value <80 ppb) based on portable sulfide monitor measurements. Clinical examination and hematological indices including inflammatory prognostic factors and halitosis measurements including organoleptic testing, portable sulfide monitor, and gas chromatography were evaluated. The genuine halitosis group showed a significantly higher white blood cell (WBC) count (p< 0.01) compared to the pseudo halitosis group. Erythrocyte sedimentation rate (ESR,β= 0.341,p< 0.05) values and duration of halitosis (β= 0.353,p< 0.05) showed a significant association with halitosis intensity and neutrophil to lymphocyte ratio (NLR) values (β= 3.859,p< 0.05) were significantly related to genuine halitosis diagnosis. A new WBC cut-off value of 5575μl-1showed near to fair discriminative power in predicting genuine halitosis (area under the curve 0.661,p< 0.05). The results of this study showing an increased WBC count in genuine halitosis and its strong association with hematologic indices of subclinical inflammation including ESR and NLR suggest inflammatory hematologic markers as potential diagnostic tools in the diagnosis of genuine halitosis.

Abstract
Halitosis is formed mainly by the volatile compounds produced by periodontal bacteria. Three volatile sulfur compounds (VSCs), hydrogen sulfide, methanethiol, and dimethyl sulfide, have attracted attention as major components of halitosis. However, these compounds cannot account for all odors. In this study, we profiled volatile compounds from the culture supernatants of periodontal bacteria using gas chromatography/mass spectrometry/olfactometry analysis with a monolithic silica gel adsorption device to investigate the potential odorous compounds. Periodontal bacteria have been found to produce volatile compounds belonging to various classes, such as alcohols, ketones, fatty acids, and aromatic compounds, in addition to VSCs. In addition, VSCs different from hydrogen sulfide and methanethiol, which are considered important causative compounds, may also influence to halitosis.

Abstract
Halitosis or oral malodor is a condition caused by the putrefaction of sulfur-containing amino acids. It affects 30–50% of the population and causes social rejection, reducing quality of life, and self-esteem. Probiotics, especially Lactobacillus species, have been proposed for the treatment of genuine halitosis, due to their ability to reduce bacterial colonization. Our objective was to evaluate their use for the treatment of oral halitosis. Applying the PRISMA statement guidelines, we searched PubMed, EMBASE, and Web of Science databases for scientific articles from the last 15 years, up to July 2021. The keywords used were “Probiotics”; “Halitosis”; “Mouth diseases”; “Oral health”; “Humans”; “Randomized Clinical Trials” according to the question, “Are probiotics effective for the reduction or elimination of oral halitosis?” Fourteen studies were identified, although only four met the inclusion criteria. We evaluated 283 participants treated with two different probiotics, with a follow-up of at least 2 weeks. Risk of bias was assessed using the Cochrane Collaboration tool. A fixed-effects meta-analysis was performed. No statistical significance was found (p = 0.53). Despite the limitations of this meta-analysis, we believe that some probiotics have a beneficial effect on halitosis, although more clinical trials are needed to establish real evidence on this aspect.Systematic Review Registration:https://doi.org/10.37766/inplasy2021.9.0009, identifier: INPLASY20211900.

Abstract
Halitosis is considered to be extremely unattractive in the context of social interactions. The main research objective of this study was to evaluate whether intra-oral halitosis may impact patients’ quality of life (QOL). One hundred generally healthy adult participants complaining about oral malodor and diagnosed with intra-oral halitosis were enrolled in this study. For halitosis diagnosis, a gas chromatography (GC) analysis by the Oral Chroma portable device was used. QOL assessment was based on the Short Form 36-item Health Survey (SF-36). The respondents had the highest scores in the physical functioning (PF), activity limitations caused by emotional problems (RE) and activity limitations caused by physical problems (RP) domains, and the weakest in the general health perception (GH), vitality (VT) and emotional wellbeing (MH) ones. The total volatile sulfur compounds (VSCs) level was negatively correlated with SF-36 domains. The SF-36 domains’ scores decreased the higher the level of VSC was. The respondents assessed their QOL to be at its best in physical functioning and activity limitations caused by emotional and physical problems and the worst in general health perception, vitality and emotional wellbeing. The strongest correlation between halitosis and decreased QOL was found in the social functioning (SF), vitality, emotional wellbeing and general health perception domains.

Abstract
Intra-oral halitosis is defined as an unpleasant odor that comes out of the mouth. The aim of this study was to investigate the effect of zinc lactate mouthwash and tongue scraping on intra-oral halitosis. The study was conducted on 60 volunteers that were divided into two groups and fol-lowed two types of 14-day oral hygiene protocols on a cross-over basis after a 7-day wash-out period. One protocol was based on tooth brushing only, while the other was based on additional mouth rinsing with a zinc lactate product and tongue scraping. Morning mouth breath was as-sessed organoleptic and by volatile sulfur compound concentrations. The highest mean organo-leptic and volatile sulfur compound measurement values were found in the tooth brushing without mouth washing and tongue scraping oral hygiene protocol (p < 0.05). The zinc lactate mouthwash combined with tongue scraping appears to be an important hygienic procedure to reduce breath odor.

Abstract
Objective: The purpose of this study was to analyze the effect of chemical method of oral hygiene practice, chlorhexidine (CHX) disinfection, and the followed consumption of probiotics on oral malodor in children. The effects of chemical and mechanical oral hygiene practice methods on the intensity of oral malodor were also evaluated. Materials and Methods: Organoleptic test (OLT) scores of 2 or more of 196 children were randomly allocated to four groups: 1: Conventional oral hygiene practices (COH) including flossing and tooth brushing, 2: COH + tongue scraping (TS), 3: COH + TS + CHX, and 4: COH + TS + CHX + probiotics. OLT was performed at 1-week and 3-month follow-ups. Results: A stable and significant number of individuals showed crucial and average levels of improvement in Group 4 OLT scores. The improvement of Group 3 OLT scores was also remarkable but not steady over the follow-ups. Neither remarkable nor steady improvements in the OLT scores was detected in Groups 1 and 2 through follow-ups. Conclusion: Oral disinfection followed by probiotic therapy with CHX may decrease the severity of oral malodor over a long period of time.

Abstract
OBJECTIVES To evaluate propolis type-3 mouthrinse effects on the concentration of volatile sulfur compounds (VSCs) and on tongue dorsum microbial profile. MATERIALS AND METHODS A three-step double-blind, crossover, randomized study with 10 individuals divided into three groups: I-placebo (P); II-ethanolic extract of propolis type-3 3% (EEP); and III-chlorhexidine 0.12% (CHX) and instructed to rinse twice daily for 5 days. Each experimental period was followed by a 21-day washout interval. Morning mouth breath was assessed by VSC concentrations and microbiological samples were obtained from tongue dorsum at baseline and the end of period of rinses and analyzed using checkerboard DNA-DNA hybridization technique for 39 bacterial species. RESULTS CHX and EEP presented the lowest VSC concentration when compared with placebo (p < 0.05). Even in the absence of mechanical plaque control, CHX and EEP treatments reduced VSC levels and there were no statistical differences for VSC measurement between CHX and EEP. There was a significant reduction in mean counts of 10 species including some VSC producers (Prevotella intermedia, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia) by EEP. Total counts of organisms, gram-negative and gram-positive bacterial species showed a decrease for EEP and CHX (p < 0.05). In addition, no statistical difference was observed between EEP and CHX (p > 0.05). A positive correlation was observed between decrease of bacterial counts and decrease of VCSs concentration for the EEP and CHX. CONCLUSIONS The use of a 3% propolis type-3 mouthrinse is an effective way to prevent morning bad breath. Thus, propolis may be a promising agent for the treatment of halitosis. CLINICAL RELEVANCE Propolis type-3 may be used as adjuvant treatment for morning breath malodor.

Abstract
Numerous oral indigenous microorganisms are constantly introduced into the stomach via the laryngopharynx, and a portion of these microorganisms irregularly reaches the lower airways and lungs. This study investigated the association between airflow limitation and the status of tongue microbiota, which is a primary source of ingested oral bacterial populations. The study population consisted of 484 community-dwelling adults aged 70–80 years inhabiting Hisayama town, Japan, who underwent a regular health examination including dental examination and spirometry test in 2016. The bacterial density and composition of their tongue microbiota were determined using a previously used 16S rRNA gene to understand their relationship with oral health conditions. The present cross-sectional study compared the tongue microbiota status between elderly individuals with airflow limitation and those with normal airflow. The total bacterial density of the tongue microbiota of individuals with airflow limitation was significantly higher than that of individuals with normal airflow. Logistic regression analysis demonstrated that a high-biomass tongue microbiota was significantly associated with airflow limitation after adjustment for smoking intensity and other covariates (adjusted OR 1.61, 95% CI 1.01–2.60). Of the predominant commensals, higher amounts of Prevotella melaninogenica and Actinomyces odontolyticus were associated with a higher prevalence of airflow limitation. These results indicate that increased bacterial burden in the tongue microbiota is associated with a higher prevalence of airflow limitation. Bacterial enrichment in the tongue microbiota is associated with airflow limitation characterising COPD in community-dwelling elderly adultshttps://bit.ly/36qMf6G

Abstract
Background: Halitosis of oral origin is very common in the general population. Due to their antimicrobial properties, chlorhexidine-based products are widely used in the management of this condition, but these are associated with reversible side effects. In this study we evaluated the efficacy of Lacer HaliTM mouthrinse and toothpaste in subjects with intraoral halitosis after several applications under normal conditions of use. Methods: In this randomized clinical trial with mouth rinse and toothpaste, single-center, double-blinded, parallel participants were assigned to an experimental group (Lacer HaliTM,, n = 20), a positive control group (HalitaTM, n = 20), and a placebo group (n = 20). The active duration of the study was 18 days. The clinical follow-up evaluations were performed at five time points (T0, T1, T2, T3, and T4). The intensity of halitosis was evaluated by organoleptic measurement and the portable gas chromatograph OralChromaTM. The data were analyzed using generalized mixed linear models. Results: Sixty patients completed the study. Lacer HaliTM, in comparison with HalitaTM, did not show statistically significant differences at any time during the study except for the levels of hydrogen sulfide and total volatile sulfur compounds at 15 days, where HalitaTM was better. Compared to the placebo treatment, Lacer HaliTM, was significantly more efficient, in terms of both the organoleptic evaluations at 8 days and the levels of hydrogen sulfide. Conclusions: Lacer HaliTM is an alternative to chlorhexidine-based toothpaste and mouthwashes in the management of halitosis.

Abstract
To determine the effect of antimicrobial photodynamic therapy (aPDT) using a red light-emitting diode (LED) on the reduction of halitosis and microbiological levels in the tongue coating immediately after irradiation, 7, 14, and 30 days after treatment. Forty-five young adults diagnosed with halitosis were allocated to three groups: G1, aPDT with 0.005% methylene blue and red LED (660 nm, four irradiation points, 90 s per point, power of 400 mW, 36 J per point, radiant exposure of 95 J/cm2, continuous wave); G2, tongue scraping; and G3, tongue scraping and aPDT. Gas chromatography was performed before and immediately after treatment, as well as at the different follow-up times. Microbiological samples were collected at the same times from the dorsum of the tongue, and bacteria were quantified in the samples using real-time PCRq. The Wilcoxon test was used for the intragroup analyses, and the Kruskal-Wallis test was used for the intergroup analyses. In the intragroup analyses, differences were found before and immediately after treatment in all groups (p < 0.05). The effect was maintained after 7 days only in the tongue scraping group (p < 0.05). In the intergroup analysis, no statistically significant differences were found among the groups (p > 0.05). For the microbiological analyses, no statistically significant differences were found in the groups/bacteria that were analyzed (p > 0.05). aPDT using a red LED and 0.005% methylene blue caused an immediate reduction in halitosis, but the effect was not maintained after 7, 14, or 30 days. No reduction occurred in the number of bacteria investigated or the quantification of universal 16S rRNA. ClinicalTrials.gov Identifier: NCT03656419.

Targeted Chemometrics Investigations of Source-, Age- and Gender-Dependencies of Oral Cavity Malodorous Volatile Sulphur Compounds. DATA 2021.

Abstract
Halitosis is a highly distressing, socially unaesthetic condition, with a very high incidence amongst the adult population. It predominantly arises from excessive oral cavity volatile sulphur compound (VSC) concentrations, which have either oral or extra-oral etiologies (90–95% and 5–10% of cases, respectively). However, reports concerning age- and gender-related influences on the patterns and concentrations of these malodorous agents remain sparse; therefore, this study’s first objective was to explore the significance and impact of these potential predictor variables on the oral cavity levels of these malodorants. Moreover, because non-oral etiologies for halitosis may represent avatars of serious extra-oral diseases, the second objective was to distinguish between etiology- (source-) dependent patterns of oral cavity VSCs. Oral cavity VSC determinations were performed on 116 healthy human participants using a non-stationary gas chromatographic facility, and following a 4 h period of abstention from all non-respiratory oral activities. Participants were grouped according to ages or age bands, and gender. Statistical analyses of VSC level data acquired featured both univariate/correlation and multivariate (MV) approaches. Factorial analysis-of-variance and MV analyses revealed that the levels of all VSCs monitored were independent of both age and gender. Principal component analysis (PCA) and a range of further MV analysis techniques, together with an agglomerative hierarchal clustering strategy, demonstrated that VSC predictor variables were partitioned into two components, the first arising from orally-sourced H2S and CH3SH, the second from extra-orally-sourced (CH3)2S alone (about 55% and 30% of total variance respectively). In conclusion, oral cavity VSC concentrations appear not to be significantly influenced by age and gender. Furthermore, (CH3)2S may serve as a valuable biomarker for selected extra-oral conditions.

Abstract
Indirectly monitoring halitosis via the detection of hydrogen sulfide (H2S) biomarkers using gas sensors is a newly emerging technique. However, such H2S sensors are required with critically high selectivity and sensitivity, as well as a ppb-level detection limit, which remains technologically challenging. To address such issues, here, we have developed highly sensitive and selective H2S sensors with NiO/WO3 nanoparticles (NPs), which have been synthesized by firstly hydrolyzing WO3 NPs and subsequently decorating with NiO NPs in a hydrothermal process. Theoretically, the NiO/WO3 NPs assist in forming a thicker electron depletion layer, adsorbing more oxygen species O2- to oxidize H2S and finally release more electrons. Beneficially, 2.1 wt % NiO/WO3 NPs show high sensitivity to H2S (Ra/Rg = 15031 ± 1370 @ 10 ppm, 100 °C), which is 42.6-fold higher than that of the pristine WO3 NPs (Ra/Rg = 353 ± 5.6 @ 10 ppm, 100 °C). Further, the H2S sensor shows ppb-level detection limit (Ra/Rg = 4.95 ± 2.9 @ 0.05 ppm, 100 °C) and high selectivity. Practically, NiO/WO3 NP sensor prototype has been employed to detect the simulated exhaled halitosis compared with that of gas chromatography, revealing a close concentration of H2S. Our investigation offers an experimental base in future intelligent medical applications.

Association of periodontitis with oral malodor in Korean adults. PLoS One 2021; 16:e0247947. [PMID: 33661974 PMCID: PMC7932065 DOI: 10.1371/journal.pone.0247947] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2020] [Accepted: 02/17/2021] [Indexed: 11/19/2022] Open
Abstract
This study aimed to evaluate the association of periodontitis with the organoleptic score (OLS)-defined oral malodor after validating OLS with odoriferous sulfur compounds in mouth air among Korean adults. A total of 330 adults aged 47–86 years were recruited from the Yangpyeong health cohort, South Korea, in 2015. Oral malodor was assessed using a 6-point OLS by a trained dentist and validated with the concentrations of hydrogen sulfide (HS) and methyl mercaptan (MM) using a gas chromatographer. Periodontitis was measured by assessing the radiographic alveolar bone loss on digital orthopantomography. Statistical analyses including descriptive statistics, partial correlation, ANOVA, and multivariable logistic regression with putative confounders were applied. OLS was significantly correlated with the concentrations of HS and MM (partial r = 0.401 and 0.392, respectively; both p<0.001) after controlling for confounders. Individuals with periodontitis had 1.8 times the risk of OLS-defined oral malodor in multivariable models (adjusted odds ratio = 1.77 in the model with the number of teeth and 1.82 in the model with denture wearing; p = 0.047 and 0.035, respectively). Periodontitis was associated with OLS-defined oral malodor among Korean adults independent of known confounders. Periodontal conditions should be considered for clinical practice and research of oral malodor.

Abstract
Objective This longitudinal study was aimed to evaluate the dynamic shift in oral microbiota during the process of halitosis progression among preschool children. Methods The oral examinations, questionnaires and tongue coating specimens were collected at the baseline and 12-month follow-up. All children were oral healthy at the enrollment. At the 12-month follow-up, children who developed halitosis were included to the halitosis group (n = 10). While children who matched the age, gender, kindergarten and without halitosis were included to the control group (n = 10). 16S rRNA gene sequencing was used to reveal the shift of the tongue coating microbiome in these children during the 12- month period with the Human Oral Microbiome Database. Results A remarkable shift in relative abundance of specific bacteria was observed prior to halitosis development. The principal coordinates and alpha diversity analyses revealed different shifting patterns of halitosis and the healthy participants’ microbiome structures and bacterial diversity over the 12-month follow-up. Both groups showed variable microbiota community structures before the onset of halitosis. Halitosis-enriched species Prevotella melaninogenica, Actinomyces sp._HMT_180 and Saccharibacteria TM7_G-1_bacterium_HMT_352 were finally selected as biomarkers in the halitosis-onset prediction model after screening, with a prediction accuracy of 91.7%. Conclusions The microbiome composition and relative abundance of the tongue coatings in the halitosis and control groups remarkably differed, even prior to the onset of the clinical manifestations of halitosis. The halitosis prediction model constructed on the basis of tongue coating microbiome biomarkers indicated the microbial shifts before the halitosis onset. Therefore, this can be considered for the timely detection and intervention of halitosis in children.

Abstract
PURPOSE The aim of the present randomized controlled clinical trial was to evaluate the efficacy of photodynamic therapy (PDT) on halitosis in adolescent patients undergoing fixed orthodontic treatment. MATERIALS AND METHODS Forty-five adolescents with halitosis undergoing orthodontic treatment were equally randomized into three groups: Group - I: provision of treatment through PDT on dorsum of tongue; Group - II: provision of treatment with the help of tongue scrappers (TS); Group - III: provision of treatment with the help of TS and adjunctive PDT. Presence of halitosis confirmed on the basis of gas chromatography and estimation of oral malodour with a cysteine challenge and H2S values recorded ≥112 parts per billion (ppb). A portable device Oral Chroma™ was used for performing breath analysis. A total of 5 bacterial species including P. gingivalis, F. nucleatum, P. intermedia, T. forsythia and T. denticola were studied as the proportion of sites defined as having ≥1.0 × 105 bacterial cells. RESULTS The mean age of the participants in Group-I, II and III were 15.4 years, 13.8 years, and 14.2 years, respectively. The median values for Group-I, II and III at initial breath analysis were 874 ppb, 613 ppb and 1089 ppb, respectively. After treatment with the respective therapeutic modalities, a statistically significant difference was seen among groups after 2-weeks (p < 0.0001) (Table 3). After applying Kruskal-Wallis test, group-III showed the highest amount of reduction in H2S concentration (100 %) at final 2-weeks breath analysis compared to group-I and group-II (p = 0.0001). Descriptive statistics for all bacteria showed that group-III (TS + PDT) statistically significantly reduced the proportional distribution of all bacteria at 2-week follow-up (p < 0.0001) compared to group-I or group-II. CONCLUSION PDT along with tongue scrapping showed effective immediate reduction of H2S concentration and reduction of oral pathogens in adolescent patients undergoing fixed orthodontic treatment with short-term follow up. Long-term evaluation and complete eradication of halitosis needs to be explored in further clinical trials. In addition, the cost of PDT and its potential side effects should not be disregarded.

Abstract
OBJECTIVE To assess the bacterial characteristics associated with intra-oral halitosis among Chinese preschool children. METHODS An epidemiological study was conducted among 273 preschool children (aged 3-4 years) in Shanghai, China, followed by the collection of 16 samples from the tongue coating of caries-free healthy and halitosis participants. The characterization of associated microbial communities was performed using 16S rRNA gene sequencing on the MiSeq. RESULTS Halitosis was observed in 13.2% of the preschool children. No significant difference in terms of microbial diversity (p > .05) was detected in the control and halitosis groups. The dominant bacterial genera observed in both groups included Prevotella, Veillonella, Streptococcus, Neisseria, Actinomyces, Haemophilus, and Leptotrichia. The relative proportions of thirteen species (including Leptotrichia sp. HMT_417, Prevotella Pallens, and Alloprevotella rava) were significantly higher in the halitosis group compared with the control group, whereas the distribution of seventeen species from genera Streptococcus, Gemella, and Kingella showed a higher abundance in the control group. Further investigation of interactions among species demonstrated obvious differences in two groups, indicating that various microorganisms interact to produce halitosis in preschool children. CONCLUSIONS Overall, halitosis is associated with multi-microbial mutual interactions. The oral flora microorganisms may exert potentiating or inhibiting effects on each other.

Abstract
A strictly anaerobic bacterial strain designated as SKVG24 was isolated from subgingival dental plaque samples of patients suffering from periodontitis. Cells were stained Gram-positive, rod shaped with endospore. The strain showed negative reaction to catalase and oxidase enzymes, but positive for gelatinase activity. Optimal growth was observed at 37 °C temperature and 7.0 pH. The 16S rRNA gene sequence BLAST analysis assigned strain SKVG24 to the genus Paraclostridium as it displayed 99.93% identity with P. benzoelyticum JC272T followed by P. bifermentans ATCC 638T (99.79%). However, average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) of the whole genome sequence showed <97% and <70% identity, respectively, with type strains of all closely related species. The G + C content of the DNA was 28.7 mol%. Total lipids profile showed presence of glycolipids as major lipids. Pathogenic features like hemolysis, gelatin hydrolysis and production of volatile sulfur compounds exhibited by strain SKVG24T were analogous to those observed in the established oral pathogenic strains. Further, whole genome sequence analysis confirmed the presence of genes encoding virulence factors and provided genomic insights on adaptation of the strain in oral environment. Based on the phenotypic and genetic differences with phylogenetic relatives, strain SKVG24T is proposed to represent a new species of the genus Paraclostridium with potential pathogenic ability, for which the name Paraclostridium dentum sp. nov., is suggested. The proposed type strain is SKVG24T (MTCC 12836T; = JCM 32760T).

Abstract
Halitosis is a common ailment concerning 15% to 60% of the human population. Halitosis can be divided into extra-oral halitosis (EOH) and intra-oral halitosis (IOH). The IOH is formed by volatile compounds, which are produced mainly by anaerobic bacteria. To these odorous substances belong volatile sulfur compounds (VSCs), aromatic compounds, amines, short-chain fatty or organic acids, alcohols, aliphatic compounds, aldehydes, and ketones. The most important VSCs are hydrogen sulfide, dimethyl sulfide, dimethyl disulfide, and methyl mercaptan. VSCs can be toxic for human cells even at low concentrations. The oral bacteria most related to halitosis are Actinomyces spp., Bacteroides spp., Dialister spp., Eubacterium spp., Fusobacterium spp., Leptotrichia spp., Peptostreptococcus spp., Porphyromonas spp., Prevotella spp., Selenomonas spp., Solobacterium spp., Tannerella forsythia, and Veillonella spp. Most bacteria that cause halitosis are responsible for periodontitis, but they can also affect the development of oral and digestive tract cancers. Malodorous agents responsible for carcinogenesis are hydrogen sulfide and acetaldehyde.

Abstract
This study was to evaluate the effect of Streptococcus salivarius K12 on tongue coating-associated halitosis. Twenty-eight subjects having tongue coating-associated halitosis were randomly divided into either a test or control group. For each of the 30 days, the test subjects sucked S. salivarius K12 tablet while the control subjects sucked placebo tablets. All the subjects did not take physical (tongue scraping) and chemical (antiseptic mouth-rinse) oral cavity pretreatment prior to use of the tablets. At baseline, and on the 1st, 7th, and 14th day after completing the course of tablets, the subjects were assessed for their organoleptic test (OLT) scores, volatile sulfur compound (VSC) levels, and tongue coating scores (TCS). During the course, all subjects kept their routine oral care habits without scraping their tongue coating. Plaque index, probing depth, and bleeding index were recorded at baseline and at the completion of the trial. On the 1st day following the end of tablet use, the OLT scores and VSC levels had significantly decreased in the test group when compared with the baseline values (P = 0.001 and P = 0.012). The TCS in the test group were also significantly decreased (P = 0.05). At days 7 and 14, the OLT scores in the test group were still significantly lower than the baseline levels (P = 0.006 and P = 0.039 respectively). However, there were no statistical differences with OLT, VSC, and TCS between the test group and the placebo group by analysis of multi-level regression model. The use of S. salivarius K12 did not have significant effect on halitosis with tongue coating cause when the tongue coating was not physically or chemically pre-treated, which implies removing tongue coating is required before Streptococcus salivarius K12 use.

Abstract
The oral cavity is a non-uniform, extraordinary environment characterized by mucosal, epithelial, abiotic surfaces and secretions as saliva. Aerobic and anaerobic commensal and pathogenic microorganisms colonize the tongue, teeth, jowl, gingiva, and periodontium. Commensals exert an important role in host defenses, while pathogenic microorganisms can nullify this protective function causing oral and systemic diseases. Every day, 750-1000 mL of saliva, containing several host defense constituents including lactoferrin (Lf), are secreted and swallowed. Lf is a multifunctional iron-chelating cationic glycoprotein of innate immunity. Depending on, or regardless of its iron-binding ability, Lf exerts bacteriostatic, bactericidal, antibiofilm, antioxidant, antiadhesive, anti-invasive, and anti-inflammatory activities. Here, we report the protective role of Lf in different oral pathologies, such as xerostomia, halitosis, alveolar or maxillary bone damage, gingivitis, periodontitis, and black stain. Unlike antibiotic therapy, which is ineffective against bacteria that are within a biofilm, adherent, or intracellular, the topical administration of Lf, through its simultaneous activity against microbial replication, biofilms, adhesion, and invasiveness, as well as inflammation, has been proven to be efficient in the treatment of all known oral pathologies without any adverse effects.

Abstract
Halitosis with the main components of trace volatile sulfur compounds widely affects the quality of life. In this study, an adaptable active sampling system with two sample-collection modes of direct injection and solid-phase microextraction was developed for the rapid and precise determination of trace volatile sulfur compounds in human halitosis coupled with gas chromatography-flame photometric detection. The active sampling system was well designed and produced for efficiently sampling and precisely determining trace volatile targets in halitosis under the optimized sampling and detection conditions. The analytical method established was successfully applied for the determination of trace targets in halitosis. The limits of detection of H2 S, CH3 SH, and CH3 SCH3 by direct injection were 0.0140-23.0 μg/L with good recoveries ranging from 82.2 to 118% and satisfactory relative standard deviations of 0.4-9.5% (n = 3), respectively. The limit of detections of CH3 SH and CH3 SCH3 by solid-phase microextraction were 2.03 and 0.186 × 10-3 μg/L with good recoveries ranging from 98.3 to 108% and relative standard deviations of 5.9-9.0% (n = 3). Trace volatile targets in positive real samples could be actually found and quantified by combination of direct injection and solid-phase microextraction. This method was reliable and efficient for the determination of trace volatile sulfur compounds in halitosis.

Abstract
Background:
Oral malodor is defined as breath that is offensive to others and its prevalence is around 35%.
Objective:
A controlled clinical double-blinded study was conducted to assess the efficacy of sugar-free tablets containing zinc lactate on oral Volatile Sulfur-containing Compounds (VSC) versus placebo tablets.
Methods:
All participants, who met the inclusion criteria, had to score a level of VSC ≥75 ppb at the basal measurement. Subjects were randomly assigned to one of the groups. The test tablet (0.7g) contained 0.255 mg of zinc lactate; the control tablet was identical but without the active agent. The OralChroma2© device was utilized to evaluate VSC. The levels were recorded at baseline, after sucking two tablets in succession and after 1 hour and 2 hours. Data were analyzed with SPSS and significance was set at α=0.05.
Results:
186 subjects completed the trial. The mean reduction from baseline at the end of tablets sucking was, respectively, 43% (p <0.001) in the control and 67% (p <0.001) in the test group, after 1 hour, it was 6% in the control (p=NS) and 25% (p <0.001) in the test group, after 2 hours, it was 3% in the control (p=NS) and 12% (p <0.001) in the test group. The comparison between the two groups after baseline adjustment showed a statistically significant difference for reductions at the end of the sucking period (p <0.001), after 1 hour (p <0.001) and after 2 hours (p <0.05).
Conclusion:
Tablets containing zinc lactate can statistically reduce the oral VSC levels immediately and for over 2 hours.

Abstract
Orthodontic braces can impede oral hygiene and promote halitosis. The aim of the study was to investigate the effect of the oral probiotic Streptococcus salivarius M18 on oral hygiene indices and halitosis in patients wearing orthodontic braces. The study was a prospective, randomized, triple-blind, placebo-controlled trial. Patients undergoing fixed orthodontic treatment were randomly allocated to a probiotic group (n = 32) and a placebo group (n = 32). Patients consumed 2 lozenges d-1 for one month. Assessments were taken at baseline, at the end of the intervention, and at a 3 month follow-up. The outcome measures were plaque index (PI), gingival index (GI) and halitosis-causing volatile sulfur compound (VSC) levels. The dental biofilms before and after the intervention were analyzed utilizing next-generation sequencing of bacterial 16S rRNA genes. PI and GI scores were not significantly influenced by the probiotic intervention (intervention × time: p > 0.05). The level of VSCs decreased significantly in both the probiotic group (VSC reduction = -8.5%, 95%CI = -7.4% to -9.1%, p = 0.015) and the placebo group (-6.5%, 95%CI = -6.0% to -7.4%, p = 0.039) after 1 month intervention. However, at the 3 month follow-up, the VSC levels in the placebo group returned to baseline levels whereas those in the probiotic group decreased further (-10.8%, 95%CI = -10.5% to -12.9%, p = 0.005). Time, but not treatment, was associated with the decrease in microbial community alpha diversity and a modest effect on beta diversity. Oral probiotic S. salivarius M18 reduced the level of halitosis in patients with orthodontic braces, but had minimal effects on PI, GI and dental biofilm microflora.

Abstract
Background To evaluate the efficacy of tulsi extract mouthrinse in reducing halitosis as compared to chlorhexidine and hydrogen peroxide mouthrinses using spectrophotometric analysis. Material and Methods It was a parallel, single center, double blinded randomized controlled trial of 15 days duration. A total of 300 participants were screened, out of which 45 subjects those fulfilled inclusion criteria of age range 17-35 years were included in the trial. The participants were randomly provided with tulsi, hydrogen peroxide or chlorhexidine mouthwashes (control group) to use 10 ml twice daily for 15 days. Clinical measurements were taken at baseline and 15 days using arbitrary 0-5 scale for organoleptic odor assessments, spectrophotometric analysis for Volatile Sulphide Compounds (VSCs) from saliva samples, Löe & Silness gingival index and Silness & Löe plaque index. Results After intervention, organoleptic, VSCs, gingival and plaque scores showed statistically significant decrease in all the three study groups. The mean percentage reduction in VSC and organoleptic scores was significantly greater in chlorhexidine and hydrogen peroxide groups than in the tulsi group and the mean percentage reduction in plaque and gingival scores was significantly greater in chlorhexidine group than in hydrogen peroxide and tulsi group. Conclusions Tulsi may not have the efficacy of chlorhexidine and hydrogen peroxide mouthrinses. But, Tulsi is effective in reducing halitosis, plaque and gingivitis and with its lack of side effects & cost effectiveness, can be an effective & economic tool to deal with halitosis. The spectrophotometric technique appears to be a promising method for evaluation of oral malodor. Key words:Halitosis, tulsi mouthwash, chlorhexidine, hydrogen peroxide, spectrophotometric analysis.

Abstract
Lactoperoxidase (LPO) present in saliva are an important element of the nonspecific immune response involved in maintaining oral health. The main role of this enzyme is to oxidize salivary thiocyanate ions (SCN-) in the presence of hydrogen peroxide (H₂O₂) to products that exhibit antimicrobial activity. LPO derived from bovine milk has found an application in food, cosmetics, and medical industries due to its structural and functional similarity to the human enzyme. Oral hygiene products enriched with the LPO system constitute an alternative to the classic fluoride caries prophylaxis. This review describes the physiological role of human salivary lactoperoxidase and compares the results of clinical trials and in vitro studies of LPO alone and complex dentifrices enriched with bovine LPO. The role of reactivators and inhibitors of LPO is discussed together with the possibility of using nanoparticles to increase the stabilization and activity of this enzyme.

Abstract
AIM This randomized controlled cross-over-design-study investigated short-term effects on oral malodour of a zinc-lactate-containing mouthwash. MATERIALS AND METHODS Sixteen subjects (18-65 years) with an organoleptic score (OLS) ≥2 were included. Following rinses were used: (A) a zinc-lactate-containing mouthwash (10 ml/30 s); (B) a zinc-lactate-containing mouthwash (15 ml/60 s); (C) a rinse without zinc-lactate (3 droplets/10 ml tap water/30 s) and (D) tap water (10 ml/30 s). Each formulation was evaluated by two blinded examiners comparing OLS and three volatile-sulphur-compounds (VSC; H2S (hydrogen sulphide), CH3SH (methyl mercaptan) and (CH3)2S (dimethyl sulphide)) before, 1 and 3 h after rinsing. Subject's perception was investigated with a visual-analogue-scale. Linear mixed models were used to compare all parameters simultaneously with respect to the four treatment groups with a significance level α < 0.05. RESULTS OLS was significantly reduced by A and B compared to C and D after 3 h (p < 0.006). The sum of the 3 VSCs as well as H2S alone were significantly reduced by rinses A and B after 1 and 3 h compared to rinses C and D (p < 0.05). Significant differences were found between the four rinses for 'Taste' (p = 0.003), for 'Change of mouth feeling' (p = 0.001), for 'Feeling of freshness' (p = 0.002) and for 'Effectiveness' (p = 0.002) in favour of A & B. CONCLUSION A zinc-lactate-containing mouthwash reduced OLS and VSC over a period of 3 h with favourable patient reported outcomes.

Abstract
Introduction L’halitose, état morbide caractérisé par une mauvaise haleine, présente à la fois un aspect pathologique et social. Dans notre contexte, l’halitose pose de nombreux problèmes de prise en charge aux plans diagnostique et thérapeutique en pratique clinique. Le but de notre travail était d’étudier les aspects diagnostiques et thérapeutiques de l’halitose. Méthodes Il s’agit d’une étude transversale sur une année. Ont été inclus, les patients âgés de plus de 15 ans qui ont consulté pour halitose au centre hospitalier universitaire Yalgado Ouédraogo. Ont été exclus les patients avec mauvaise haleine mais consultant pour un autre motif. L’haleine a été évaluée par un praticien selon le test organoleptique de Rosenberg. Résultats Au total 35 patients ont été inclus pour un sex-ratio de 1,2. L’âge moyen était de 31,9 ans. Dans 57,1% des cas, la plainte venait du patient lui-même. La durée moyenne de l’halitose était de 4,3 ans. Dix-neuf patients avaient un score de Mel Rosenberg ≥ 2. La carie dentaire (07 cas), la sinusite (07 cas), l’infection à Helicobacter pylori (09 cas) et l’ulcère gastro-intestinal (10 cas) étaient associés à l’halitose. Le traitement a été étiologique dans 82.9% des cas avec une amélioration satisfaisante à deux semaines de l’ordre de 71,8%. Conclusion L’halitose reste une pathologie peu étudiée et pose un problème de diagnostic positif, mais aussi étiologique dans notre contexte. Le rôle de l’odontologiste est crucial dans la recherche de la cause de l’halitose. Cependant, une prise en soins pluridisciplinaire de l’halitose permettra d’y apporter une réponse plus efficace.
