[PMID: 38769314 PMCID: PMC11106080 DOI: 10.1038/s41405-024-00221-8] [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: 02/21/2024] [Revised: 04/22/2024] [Accepted: 04/23/2024] [Indexed: 05/22/2024] Open
Abstract
INTRODUCTION Intra-oral halitosis (IOH) is the most common type of bad breath; its consequences impair quality of life. However, evidence-based treatment protocols and guidelines are lacking. Our aim is to investigate the effectiveness of chlorine dioxide as an applicable complementary treatment modality in IOH after tongue cleaning. METHODS AND ANALYSIS The ODOR trial will be a single-center, double-blinded, parallel-group, double-armed pilot randomized controlled trial with a non-inferiority design. The efficacy of hyperpure chlorine dioxide will be compared to chlorhexidine mouthwash. We plan to investigate the short-term effects of the intervention over a 3-h period. The primary endpoint will be changes in organoleptic test scores. At the end of the pilot investigation of the first 30 patients each, sample size calculation will be performed. If feasible, the investigators will continue the study by enrolling more patients. TRIAL REGISTRATION The trial has been registered at ClinicalTrials.gov (NCT06219226).

[PMID: 37985343 PMCID: PMC10988250 DOI: 10.1016/j.identj.2023.10.002] [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: 05/11/2023] [Revised: 09/26/2023] [Accepted: 10/09/2023] [Indexed: 11/22/2023] Open
Abstract
BACKGROUND Tongue coating consists of oral bacteria, desquamated epithelium, blood cells, and food residues and is involved in periodontal disease, halitosis, and aspiration pneumonia. Recently, a tongue brush with sonic vibration was developed to clean the tongue. This comparative study examined the extent of tongue coating, its effects on the tongue, bacterial count particularly on the posterior dorsum of the tongue, and the degree of pain using a manual tongue brush and the newly developed sonic tongue brush. MATERIALS AND METHODS Patients' extent of tongue coating and the quantity of bacteria were analysed before and after brushing with a sonic or manual nylon tongue brush. Moreover, the impressions of the dorsum linguae were obtained before and after brushing to establish models that were observed under a stereo microscope to evaluate tongue trauma. Pain caused during the use of these brushes was evaluated based on the numerical rating scale (NRS). RESULTS The extent of tongue coating and number of bacteria decreased in both the sonic and manual nylon brush groups after tongue cleaning; however, no significant differences were noted. Tongue trauma evaluation revealed that the tongue surface was significantly scratched in the manual brush group compared with the sonic brush group. NRS-based pain evaluation revealed no significant differences. CONCLUSIONS The sonic brush was equally effective in removing tongue coating and bacteria compared with the manual brush. As the sonic brush does not cause tongue trauma, it may be considered a safe and effective cleaning tool of the tongue.

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
Objective To evaluate parents’ knowledge about halitosis, and to compare parents’ perception of halitosis in their children to the presence of halitosis clinically. Methods Children between 3 and 8 years attended to Dental University Hospital, King Saud University, were screened. Children satisfying inclusion criteria and their parents agreed to participate were included. Questionnaires regarding parents’ knowledge and perception about halitosis in their children were filled by attending parents. Then, the assessment of halitosis in the participating children carried out by portable gas chromatograph device (OralChromaTM). Results A total of 67 children (44 girls and 23 boys) were included in this study with a mean age of 5.3 years (SD = 1.7). The majority of the questionnaires (n = 44, 65.7%) were filled by accompanying fathers. One in two (52.2%) parents obtained high knowledge score about halitosis. Parents’ knowledge was significantly associated with the mean age of the children (P = 0.02). Thirty-nine (58.2%) parents perceived halitosis in their children. Gender, child’s age, parents’ education level, or family income were not associated with parents’ perception of halitosis. Halitosis was detected clinically in 58 children (86.6%). Thirty-eight (57%) of parents’ perception of halitosis was in consistency with OralChromaTM readings; however, there was no significant association between parents’ perception and the OralChromaTM score. Conclusion Half of the parents had good knowledge about halitosis and 6 in 10 parents perceived halitosis in their children which is quite less than the presence of halitosis detected clinically. Moreover, parents’ perception was not associated with the OralChromaTM score.

Abstract
OBJECTIVES The aim of this research is to gain more insight in the methods and experiences of dental hygienists in the Netherlands regarding the treatment of patients with halitosis. MATERIAL AND METHODS A total of 92 dental hygienists completed the questionnaire (consisting of 19 questions on personal and professional characteristics, clinical observation and treatment of halitosis, the referral of patients with halitosis, the presence and usefulness of a protocol). The questionnaire was distributed using a social media platform for dental professionals in oral health care from all over the Netherlands. RESULTS 83.4% of 90 dental hygienists had paid attention to the patient's breath but only 37.8% of dental hygienists always informed the patient. Reasons for not informing patients were the fear of the patient's possible reaction or because other oral health problems were more important. Of the included dental hygienists 67.8% had never referred a patient for treatment of halitosis. 86.7% of the dental hygienists stated there was no protocol for diagnosis and treatment of patients with halitosis. However, 90.0% of the dental hygienists acknowledged a protocol would be useful. CONCLUSIONS The majority of the dental hygienists in the Netherlands had paid attention to the patient's breath, but only a small group of dental hygienists informed their patients about halitosis. In dental practices halitosis is an underestimated problem. During the coronavirus pandemic people are more aware with the smell of their breath. Dental hygienists indicated scaling and root planning and/or providing information and instruction by patients with a bad breath.

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
BACKGROUND In this study, we aimed to evaluate the salivary β-galactosidase and Halimeter values (HMV), organoleptic scores (OLS) and Winkel tongue coating index (WTCI) in periodontal health and periodontitis (P), and also their changes after phase I periodontal therapy and tongue cleaning. METHODS The participants were separated as follows: 25 P with halitosis (Group 1), 25 P without halitosis (Group 2) and 25 healthy controls (Group 3). Periodontal recordings, HMV, OLS and WTCI scores were recorded, and whole saliva β-galactosidase levels were measured colorimetrically in the samples at baseline and 1 month after the therapy. RESULTS The baseline values of HMV, OLS, WTCI and salivary β-galactosidase levels were significantly higher in Group 1 than in Group 2 (P < 0.05). There was a statistically significant decrease in periodontal recordings, HMV, OLS, WTCI and salivary β-galactosidase levels in all P patients by the therapy (P < 0.05). However, major reductions in halitosis measurements and saliva enzyme levels were observed in Group 1 after the treatment. CONCLUSION Our results showed that salivary β-galactosidase was associated with halitosis parameters and phase I periodontal therapy played an important role to reduce this enzyme level and halitosis parameters in P.

Abstract
Background/purpose Halitosis is the unpleasant and offensive odour in exhaled air, which is linked to the presence of volatile sulphur compounds (VSC). Different mouthwashes have been used to treat halitosis. The objective of this study was to test the effect of an antioxidant (AO) mouthwash, and mouthwash containing [0.05% chlorhexidine, 0.05% cetylpyridinium chloride, and 0.14% zinc lactate (CHX-CPC-Zn)] on VSC. Material and methods Thirty-five subjects with halitosis participated in this clinical trial. At the baseline visit, a breath sample was taken and analyzed for the level of hydrogen sulphide (H2S), methyl mercaptan (CH3SH), and dimethyl sulphide (CH3SCH3) using portable gas chromatography (OralChroma™). Two mouthwashes were randomly provided to each subject in addition to saline solution (NaCl 0.9%) as control. Subjects were instructed to rinse with 20 ml of the mouthwash for 1 min twice daily for 2 weeks. At second visit, post-treatment breath sample was taken. Afterward, the patient was asked to refrain from using mouthwash for a washout period of 1 week. A similar procedure was repeated for each mouthwash interval. Results No significant differences in VSC level between all three groups were detected at baseline. A significant reduction in VSC level was obtained after using CHX-CPC-Zn mouthwash. On other hand, both AO mouthwash and saline had no significant impact on the level of VSC. Conclusion CHX-CPC-Zn mouthwash has a significant effect on VSC level reduction in subjects with confirmed halitosis. Besides, using AO mouthwash regularly for 2 weeks did not have any impact on improving the level of halitosis.

Abstract
BACKGROUND The aim of the study was to observe the antimicrobial activity of Porphyromonas gingivalis and Treponema denticola as well as the effect on reducing volatile sulfur compounds (VSCs). MATERIALS AND METHODS After P. gingivalis and T. denticola were cultured with or without Streptococcus salivarius K12 and M18, VSCs were measured by Oral Chroma. In order to analyze the mechanism for malodor control, the antimicrobial activity of S. salivarius K12 and M18 against P. gingivalis and T. denticola was assessed. SPSS 21.0 was used for data analysis with the Kruskal-Wallis and Jonckheere-Terpstra tests. Mann-Whitney test was applied for post hoc analysis. RESULTS P. gingivalis and T. denticola VSC levels were reduced by high concentrations of S. salivarius K12 and M18 during coculture. The concentrations were lower than those of single culture (p < .05). An antimicrobial effect was detected on P. gingivalis, and T. denticola by 50% S. salivarius K12 and M18. The spent culture medium and whole bacteria of S. salivarius K12 and M18 reduced the levels of VSCs below the amount in a single culture of P. gingivalis and T. denticola (p < .05). CONCLUSION S. salivarius K12 and M18 decreased the levels of VSCs originating from P. gingivalis and T. denticola.

Abstract
BACKGROUND Halitosis or bad breath is a symptom in which a noticeably unpleasant breath odour is present due to an underlying oral or systemic disease. 50% to 60% of the world population has experienced this problem which can lead to social stigma and loss of self-confidence. Multiple interventions have been tried to control halitosis ranging from mouthwashes and toothpastes to lasers. This new Cochrane Review incorporates Cochrane Reviews previously published on tongue scraping and mouthrinses for halitosis. OBJECTIVES The objectives of this review were to assess the effects of various interventions used to control halitosis due to oral diseases only. We excluded studies including patients with halitosis secondary to systemic disease and halitosis-masking interventions. SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 8 April 2019), the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 3) in the Cochrane Library (searched 8 April 2019), MEDLINE Ovid (1946 to 8 April 2019), and Embase Ovid (1980 to 8 April 2019). We also searched LILACS BIREME (1982 to 19 April 2019), the National Database of Indian Medical Journals (1985 to 19 April 2019), OpenGrey (1992 to 19 April 2019), and CINAHL EBSCO (1937 to 19 April 2019). The US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov (8 April 2019), the World Health Organization International Clinical Trials Registry Platform (8 April 2019), the ISRCTN Registry (19 April 2019), the Clinical Trials Registry - India (19 April 2019), were searched for ongoing trials. We also searched the cross-references of included studies and systematic reviews published on the topic. No restrictions were placed on the language or date of publication when searching the electronic databases. SELECTION CRITERIA We included randomised controlled trials (RCTs) which involved adults over the age of 16, and any intervention for managing halitosis compared to another or placebo, or no intervention. The active interventions or controls were administered over a minimum of one week and with no upper time limit. We excluded quasi-randomised trials, trials comparing the results for less than one week follow-up, and studies including advanced periodontitis. DATA COLLECTION AND ANALYSIS Two pairs of review authors independently selected trials, extracted data, and assessed risk of bias. We estimated mean differences (MDs) for continuous data, with 95% confidence intervals (CIs). We assessed the certainty of the evidence using the GRADE approach. MAIN RESULTS We included 44 trials in the review with 1809 participants comparing an intervention with a placebo or a control. The age of participants ranged from 17 to 77 years. Most of the trials reported on short-term follow-up (ranging from one week to four weeks). Only one trial reported long-term follow-up (three months). Three studies were at low overall risk of bias, 16 at high overall risk of bias, and the remaining 25 at unclear overall risk of bias. We compared different types of interventions which were categorised as mechanical debridement, chewing gums, systemic deodorising agents, topical agents, toothpastes, mouthrinse/mouthwash, tablets, and combination methods. Mechanical debridement: for mechanical tongue cleaning versus no tongue cleaning, the evidence was very uncertain for the outcome dentist-reported organoleptic test (OLT) scores (MD -0.20, 95% CI -0.34 to -0.07; 2 trials, 46 participants; very low-certainty evidence). No data were reported for patient-reported OLT score or adverse events. Chewing gums: for 0.6% eucalyptus chewing gum versus placebo chewing gum, the evidence was very uncertain for the outcome dentist-reported OLT scores (MD -0.10, 95% CI -0.31 to 0.11; 1 trial, 65 participants; very low-certainty evidence). No data were reported for patient-reported OLT score or adverse events. Systemic deodorising agents: for 1000 mg champignon versus placebo, the evidence was very uncertain for the outcome patient-reported visual analogue scale (VAS) scores (MD -1.07, 95% CI -14.51 to 12.37; 1 trial, 40 participants; very low-certainty evidence). No data were reported for dentist-reported OLT score or adverse events. Topical agents: for hinokitiol gel versus placebo gel, the evidence was very uncertain for the outcome dentist-reported OLT scores (MD -0.27, 95% CI -1.26 to 0.72; 1 trial, 18 participants; very low-certainty evidence). No data were reported for patient-reported OLT score or adverse events. Toothpastes: for 0.3% triclosan toothpaste versus control toothpaste, the evidence was very uncertain for the outcome dentist-reported OLT scores (MD -3.48, 95% CI -3.77 to -3.19; 1 trial, 81 participants; very low-certainty evidence). No data were reported for patient-reported OLT score or adverse events. Mouthrinse/mouthwash: for mouthwash containing chlorhexidine and zinc acetate versus placebo mouthwash, the evidence was very uncertain for the outcome dentist-reported OLT scores (MD -0.20, 95% CI -0.58 to 0.18; 1 trial, 44 participants; very low-certainty evidence). No data were reported for patient-reported OLT score or adverse events. Tablets: no data were reported on key outcomes for this comparison. Combination methods: for brushing plus cetylpyridium mouthwash versus brushing, the evidence was uncertain for the outcome dentist-reported OLT scores (MD -0.48, 95% CI -0.72 to -0.24; 1 trial, 70 participants; low-certainty evidence). No data were reported for patient-reported OLT score or adverse events. AUTHORS' CONCLUSIONS We found low- to very low-certainty evidence to support the effectiveness of interventions for managing halitosis compared to placebo or control for the OLT and patient-reported outcomes tested. We were unable to draw any conclusions regarding the superiority of any intervention or concentration. Well-planned RCTs need to be conducted by standardising the interventions and concentrations.

Abstract
BACKGROUND: Halitosis is one of the unpleasant conditions which could alter the self-confidence and cause serious illness. One of the treatments to overcome halitosis is by using mouthwash. Plectranthus amboinicus (Lour.) Spreng is one of the plants that is known to have antibacterial activity which can be used to overcome halitosis caused bacteria. AIM: To formulate the Plectranthus amboinicus (Lour.) Spreng leaves ethanolic extract as herbal mouthwash and to evaluate the antibacterial activity against Streptococcus mutans and Staphylococcus aureus bacteria. METHODS: The methods of the study included the characterization and screening of Plectranthus amboinicus (Lour.) Spreng leaves dried powder; the extraction process by maceration using 96% ethanol; the antibacterial activity test of Plectranthus amboinicus (Lour.) Spreng leaves ethanolic extract and the formulation and evaluation of mouthwash dosage form with various concentrations of Plectranthus amboinicus (Lour.) Spreng leaves ethanolic extract. RESULTS: The characterization results showed that the Plectranthus amboinicus (Lour.) Spreng leaves powder contained 7.92% of water, 29.26% of water-soluble substance, 13.32% of ethanol soluble substance, 0.82% of total ash and 0.66% of acid insoluble ash. The screening examination gave glycoside, saponin, flavonoid, tannin and steroid/triterpenoid positive results. The antibacterial activity test of the Plectranthus amboinicus (Lour.) Spreng mouthwash showed that the dosage form with 2% of Plectranthus amboinicus (Lour.) Spreng extract successfully inhibited the growth of bacteria with 12.00 and 11.25 mm of inhibition diameter for both Staphylococcus aureus and Streptococcus mutans, respectively. CONCLUSION: The Plectranthus amboinicus (Lour.) Spreng leaves ethanolic extract can be formulated in mouthwash dosage form and has antibacterial activity against Staphylococcus aureus and Streptococcus mutans bacteria.

Sun X, Yang X, Xue P, Zhang Z, Ren G. Improved antibacterial effects of alkali-transformed saponin from quinoa husks against halitosis-related bacteria. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 19:46. [PMID: 30755185 PMCID: PMC6373059 DOI: 10.1186/s12906-019-2455-2] [Citation(s) in RCA: 22] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/24/2017] [Accepted: 02/05/2019] [Indexed: 11/10/2022]
Abstract
Background Quinoa is a food crop native to the Andes. The process of dehulling quinoa can produce approximately 8–12% husk, which is often discarded because it contains bitter saponin. Saponin derived from quinoa has been reported to exhibit anti-inflammatory and antifungal activity. However, the antibacterial effects of quinoa saponin against halitosis-related bacteria are still unclear. Methods In this study, quinoa saponin (QS) and alkali-transformed saponin (ATS) were separated by AB-2 resin to obtain QS-30, QS-80, ATS-30 and ATS-80. Halitosis-related bacteria included Porphyromonas gingivalis (P. gingivalis), Clostridium perfringens (C. perfringens) and Fusobacterium nucleatum (F. nucleatum). The MIC and MBC were determined using gradient dilutions in 96-well plates, and the saponins were identified by HPLC and mass spectrometry. The changes in membrane integrity were tested using a microplate reader, the membrane potential was tested by spectrofluorometry, and the morphological characteristics were examined using a transmission electron microscope to explore the antibacterial mechanisms. Results Antibacterial assays indicated that QS-80 and ATS-80 showed inhibitory activity. In addition, ATS-80 exerted a stronger inhibitory effect than QS-80, especially against Fusobacterium nucleatum, with a lower minimum inhibitory concentration (31.3 μg/mL) and a lower minimum bactericidal concentration (125 μg/mL). ATS-80 destroyed the bacterial membrane structure, leading to bacterial death. Conclusions Based on the excellent antibacterial activity and economic prospects of quinoa husk, ATS-80 could be used as an antibacterial agent to treat halitosis.

Abstract
OBJECT Halitosis has great adverse impact on personal and social life. There is no strong evidence for the effect of Chinese medicine (CM) and combined Chinese and western medicine (CWM) on halitosis. The aim of the present study is to evaluate the effective rate of CM and CWM on halitosis. MATERIALS AND METHODS Literature search in English and Chinese was conducted in PubMed, Embase, CNKI, CBM, and Wanfang database. Study selection and data collection were conducted. Risks of bias were assessed by the Cochrane tool. Synthesis of results was done by RevMan 5.3. p<0.05 was considered significant difference. Subgroup analysis by classification of halitosis and sensitivity analysis were also conducted. RESULTS Seventeen studies were included. The follow-up length ranged from five days to eight weeks. CM had significantly better effect than WM on intraoral halitosis (I2 =24%; RR=1.21 (95% CI, 1.04, 1.40), P=0.01) and extraoral halitosis (I2 =0; RR=1.39 (95% CI, 1.19, 1.63), P<0.0001). CWM had significantly better effect than WM on intraoral halitosis (I2 =0; RR=1.25 (95% CI, 1.16, 1.35), P<0.00001) and extraoral halitosis (I2 =0; RR=1.19 (95% CI, 1.08, 1.31), P=0.0004). Subgroup analysis and sensitivity analysis showed insignificant results. CONCLUSION With the limitation of our study, both CM and CWM have significantly better effect on halitosis than WM. More effort should be made to explore long-term effect of CM and CWM on halitosis. This study was registered with the PROSPERO (ID: CRD42018107229).

[PMID: 30385826 PMCID: PMC6212478 DOI: 10.1038/s41598-018-34366-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Accepted: 10/12/2018] [Indexed: 01/18/2023] Open
Abstract
Mature biofilms are highly resistant to antimicrobial agents due to the presence of extracellular polymeric substances (EPS), which inhibit the penetration of external molecules. In this study, we developed a coordination compound consisting of zinc chloride and erythritol that exhibits penetrating and bactericidal activity against Streptococcus mutans biofilms. An in vitro biofilm model was established in microplates, and bactericidal activity against biofilms was evaluated using an Alamar blue assay. The cause of the antimicrobial activity of the zinc-erythritol mixture on mature biofilms was demonstrated using fast atom bombardment-mass spectrometry, confocal laser scanning microscopy and atomic force microscopy. We demonstrated that zinc chloride spontaneously formed cationic complexes with erythritol in water. The zinc-erythritol complexes reduced intra- and inter-molecular interactions between bacterial exopolysaccharides, a major component of EPS. This activity was confirmed by measuring the attenuation of the hardness of dried polysaccharides isolated from S. mutans biofilms. The reduction in the interactions between polysaccharides allowed the complexes to penetrate into biofilms and kill the embedded bacteria. While approximately 13% of biofilm-associated microbes were killed by a 10 min treatment with 6.6 mM zinc chloride, 45% were killed when a solution containing 19.8 mM erythritol and 6.6 mM zinc chloride was used. This strategy of leveraging the coordination properties of metal ions with sugar alcohols provides a simple way to effectively remove mature biofilms using only conventional substances without the need for intricate chemical synthesis processes.

Abstract
INTRODUCTION Oral malodour is a social malady affecting people of all the age groups. Effective management of oral malodour is the key to improve the quality of life of such people. AIM To evaluate the effectiveness of ayurvedic medication, G32 in controlling oral malodour and comparing the effects with Chlorhexidine (CHX). MATERIALS AND METHODS This was a single blind randomized controlled trial with parallel study design conducted at a hospital in the city of Udupi in Southern India. A total of 40 patients suffering with oral malodour, aged 17-35 years, were included in this trial. After inclusion into the study, the subjects were examined twice, with a one-week interval between both examinations. Volatile Sulphur Compounds (VSCs), gingival, plaque and tongue coating scores were assessed at both examinations. Subjects were randomly allocated to G32 group - ayurvedic formulation (intervention group) and CHX group (control group), and were provided with the respective formulations enough to be used twice daily for a period of one week. The difference between the mean scores of VSCs, plaque, and gingivitis and tongue coating were compared within the intervention and control groups, respectively, using paired t-test. RESULTS Both test and control groups showed a significant reduction in VSCs, plaque and gingivitis levels. The percentage reductions in VSCs, plaque and gingivitis were found to be similar among the two groups. There was no significant difference between the preintervention and postintervention scores in both the groups. CONCLUSION G32, an ayurvedic medication, can be an effective tool to deal with oral malodour.

Abstract
Objective Halitosis can be caused by microorganisms that produce volatile sulphur compounds (VSCs), which colonize the surface of the tongue and subgingival sites. Studies have reported that the use of natural products can reduce the bacterial load and, consequently, the development of halitosis. The aim of this study was to evaluate the antimicrobial activity of the essential oil of Melaleuca alternifolia on the growth and volatile sulphur compound (VSC) production of oral bacteria compared with chlorhexidine. Material and Methods The effects of these substances were evaluated by the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) in planktonic cultures of Porphyromonas gingivalis and Porphyromonas endodontalis. In addition, gas chromatography analyses were performed to measure the concentration of VSCs from bacterial cultures and to characterize M. alternifolia oil components. Results The MIC and MBC values were as follows: M. alternifolia - P. gingivalis (MIC and MBC=0.007%), P. endodontalis (MIC and MBC=0.007%=0.5%); chlorhexidine - P. gingivalis and P. endodontalis (MIC and MBC=1.5 mg/mL). M. alternifolia significantly reduced the growth and production of hydrogen sulfide (H2S) by P. gingivalis (p<0.05, ANOVA-Dunnet) and the H2S and methyl mercaptan (CH3SH) levels of P. endodontalis (p<0.05, ANOVA-Dunnet). Chlorhexidine reduced the growth of both microorganisms without altering the production of VSC in P. endodontalis. For P. gingivalis, the production of H2S and CH3SH decreased (p<0.05, ANOVA-Dunnet). Conclusion M. alternifolia can reduce bacterial growth and VSCs production and could be used as an alternative to chlorhexidine.

Abstract
Hydrogen sulfide (H2S) is emitted from industrial activities, and several chemotrophs possessing Sox enzymes are used for its removal. Oral malodor is a common issue in the dental field and major malodorous components are volatile sulfur compounds (VSCs), including H2S and methyl mercaptan. Paracoccus pantotrophus is an aerobic, neutrophilic facultatively autotrophic bacterium that possesses sulfur-oxidizing (Sox) enzymes in order to use sulfur compounds as an energy source. In the present study, we cloned the Sox enzymes of P. pantotrophus GB17 and evaluated their VSC-degrading activities for the prevention of oral malodor. Six genes, soxX, soxY, soxZ, soxA, soxB, and soxCD, were amplified from P. pantotrophus GB17. Each fragment was cloned into a vector for the expression of 6×His-tagged fusion proteins in Escherichia coli. Recombinant Sox (rSox) proteins were purified from whole-cell extracts of E. coli using nickel affinity chromatography. The enzyme mixture was investigated for the degradation of VSCs using gas chromatography. Each of the rSox enzymes was purified to apparent homogeneity, as confirmed by SDS-PAGE. The rSox enzyme mixture degraded H2S in dose- and time-dependent manners. All rSox enzymes were necessary for degrading H2S. The H2S-degrading activities of rSox enzymes were stable at 25–80°C, and the optimum pH was 7.0. The amount of H2S produced by periodontopathic bacteria or oral bacteria collected from human subjects decreased after an incubation with rSox enzymes. These results suggest that the combination of rSox enzymes from P. pantotrophus GB17 is useful for the prevention of oral malodor.

Abstract
Aim. To assess self-reported halitosis, oral hygiene practices, oral health conditions, general health problems, sociodemographic factors, and behavioural and psychological characteristics among workers in Ilala and Temeke municipals. Materials and Methods. This was a cross-sectional descriptive study. Four hundred workers were recruited using a self-administered structured questionnaire. Results. Self-reported tooth brushing practice was 100%, tongue cleaning 58.5%, dental flossing 4.3%, gum bleeding on tooth brushing 79.3%, presence of hard deposits on teeth 32%, mobile teeth 15.3%, and self-reported halitosis (SRH) 48.5%. Tea users were 95%, coffee users 75.8%, smokers 21%, and alcohol consumers 47%. The SRH was significantly associated with bleeding gums, hard deposits, and mobile and malaligned teeth. Tongue cleaning and regular change of toothbrush were associated with low prevalence of SRH (P < 0.001). Higher occurrence of SRH was significantly related to low education and smoking. Conclusion. Self-reported halitosis was prevalent among workers and was significantly associated with bleeding gums, hard dental deposits, mobile teeth, and smoking. All participants brushed their teeth and cleaned the tongue regularly but use of dental floss was extremely low. Oral health education and health promotion are recommended.

Abstract
Background Self-perceived halitosis could be a symptom of a psychosomatic or psychogenic disorder. The aim of this cross-sectional study was to clarify the relationship of self-perceived halitosis with psychological and oral health statuses. Methods One hundred participants with a history of halitosis were enrolled from a teaching hospital. They were divided into the self-perceived and suggested groups if they sensed and did not sense the malodor, respectively. Demographic and socioeconomic information, smoking status, and oral hygiene practices were noted. Complete nasal, oral, and periodontal examinations with organoleptic tests (OLTs) and N-benzoyl-DL-arginine-2-naphthylamide (BANA) tests were conducted. The participants also completed the validated Arabic version of the 90-item revised symptom checklist (SCL-90R). Data were compared by analysis of variance, chi-square test, Student’s t-test, and multivariate logistic regression. Results The self-perceived group had higher OLT scores (p = 0.005) and were significantly younger (p = 0.001) than the suggested group. A significantly higher number of its participants were smokers (p = 0.004). No significant differences were observed in socioeconomic information, oral hygiene practices, oral conditions, and BANA test results. Further, no significant association was noted between self-perceived halitosis and the nine psychological dimensions of SCL-90R. Conclusions Halitosis is a multifactorial symptom that requires multidisciplinary management. Self-reporting of the condition is unique entity and trust worthy symptom. It tends to be related to nonoral pathologies and extrinsic causes such as smoking.

Abstract
Background Breath odor is a nuisance problem for many people around the world. Bad breath affects social interactions of people in daily life by causing personal discomfort and emotional stress. There are chemical and mechanical methods for controlling oral malodor. Many studies of various mouth rinse applications and tongue cleaning procedures have been conducted. However, few studies have compared the effect of simultaneous chemical and mechanical procedures on the reduction of volatile sulfur compounds (VSCs) in subjects with oral malodor. The purpose of this study was to assess the effects of different oral hygiene procedures on reduction of VSCs in subjects with oral malodor. Methods Thirty male volunteers who matched with study criteria were divided randomly into two groups. Both groups performed tooth brushing, mouth washing with chlorine dioxide, tongue cleaning and combination of those in different sequence for five weeks. Total VSCs of subjects were measured with a Breathtron®, and oral health status was also examined. Quantitative analyses were performed using the Statistical Package for Social Science (SPSS 16.0). Results There were no significant differences in oral health status between the two groups at the baseline. No significant decrease in oral malodor was detected after one week of tooth brushing. Significant reductions in VSCs were shown by adding mouthwash or tongue cleaning to tooth brushing from the second week to fourth week (P <0.01). The greatest reduction in VSCs was found at the fifth week after the practice of all three oral hygiene regimens. Conclusions Tooth brushing alone does not significantly reduce oral malodor. Mouth washing and tongue cleaning significantly reduce oral malodor, but combining tooth brushing, mouth washing and tongue cleaning regimens is most effective for oral malodor reduction. The results of this study could contribute to the formulation of appropriate preventive strategies against oral malodor not only for the general public but also for dental professionals serving as oral malodor-related service providers.

J Appl Oral Sci 2015; 23:64-70. [PMID: 25760268 PMCID: PMC4349121 DOI: 10.1590/1678-775720140223] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2014] [Accepted: 10/30/2014] [Indexed: 01/10/2023] Open
Abstract
OBJECTIVE Acetaldehyde is the first metabolite of ethanol and is produced in the epithelium by mucosal ALDH, while higher levels are derived from microbial oxidation of ethanol by oral microflora such as Candida species. However, it is uncertain whether acetaldehyde concentration in human breath is related to oral condition or local production of acetaldehyde by oral microflora. The aim of this pilot study was to investigate the relationship between physiological acetaldehyde concentration and oral condition in healthy volunteers. MATERIAL AND METHODS Sixty-five volunteers (51 males and 14 females, aged from 20 to 87 years old) participated in the present study. Acetaldehyde concentration in mouth air was measured using a portable monitor. Oral examination, detection of oral Candida species and assessment of alcohol sensitivity were performed. RESULTS Acetaldehyde concentration [median (25%, 75%)] in mouth air was 170.7 (73.5, 306.3) ppb. Acetaldehyde concentration in participants with a tongue coating status score of 3 was significantly higher than in those with a score of 1 (p<0.017). After removing tongue coating, acetaldehyde concentration decreased significantly (p<0.05). Acetaldehyde concentration was not correlated with other clinical parameters, presence of Candida species, smoking status or alcohol sensitivity. CONCLUSION Physiological acetaldehyde concentration in mouth air was associated with tongue coating volume.

Abstract
Background: Halitosis or oral malodor is characterized by unpleasant odor arising from the oral cavity. The prevalence of halitosis however is not studied extensively. The aim of this study was to evaluate the self perception of oral malodor and oral hygiene habits amongst dental students. Materials and Methods: A structured questionnaire consisting of ten questions was administered to 285 undergraduate students of Madha Dental College and Hospital. The questionnaire was designed to evaluate the self perception of halitosis, oral hygiene aids used, presence of dental caries, gingival bleeding, and dryness of mouth. Results: Of the 285 students, 259 students completed the questionnaire. The response rate was 90%, with male response rate being 85.7% and female 95.8%. Self-perceived halitosis was reported by 44.1% males and 45.32% females. The difference in reporting self-perception of halitosis between females and males was found to be statistically significant (P < 0.05). Significant difference was found for use of mouth wash, presence of carious teeth, bleeding gums, and use of tongue cleaners between females and males (P < 0.05). Conclusion: The results of this study indicate higher prevalence of halitosis among this population consisting of dental students. The awareness of halitosis was also higher among this population. The awareness of halitosis as an individual entity should be promoted to the general population and the therapeutic measures should be made available to all.

Abstract
BACKGROUND The principal components of halitosis are volatile sulfur compounds (VSCs) such as hydrogen sulfide, methyl mercaptan, and dimethylsulfide or compounds such as butyric acid, propionic acid, putrescine, and cadaverine. OBJECTIVE The aim of this study was to evaluate the effect of Chinese herbs on VSCs in vitro. METHODS Saliva samples from volunteers were used as the source for the evaluation of bacterial activity and VSC inhibition. Extracted substances from Chinese herbs were identified by VSC inhibition tests with a Halimeter and microbial sensitivity testing. The effectiveness on halitosis was compared between a dentifrice containing one of the effective Chinese herbs (ie, chrysanthemum flower [Chrysanthemum morifolium flos]), 4 commercially available antihalitosis dentifrices, and a positive control that received no treatment. RESULTS Ten volunteers provided saliva samples for VSC testing. Of the 40 herbs tested, 14 extracts had percent inhibition rates of VSCs >50%. Ten herbs showed greatest effect against all culturable microorganisms with bacterial inhibition >70%. There was a weak positive correlation between bacteriostasis and the anti-VSC activity of the herbs with a correlation coefficient of 0.2579 (Pearson). The mean (SD) values of the VSC testing were as follows: dentifrice containing chrysanthemum flower, 55.91 (8.16) ppb; Crest Tea Refreshing Dentifrice®, 48.39 (7.48) ppb (P = NS); Cortex Phellodendri Dentifrice®, 139.90 (14.70) ppb (P < 0.01); Colgate Total Plus Whitening®, 120.94 (15.58) ppb (P < 0.01); Zhong Hua Chinese Herbs Dentifrice®, 136.96 (13.06) ppb (P < 0.01); and positive control, 312.38 (28.58) ppb (P < 0.01). CONCLUSIONS Of 40 herbs tested, 14 Chinese herbs were found to be effective for VSC inhibition. A dentifrice containing chrysanthemum flower reduced the formation of VSC in vitro, showing a significantly greater effect than the control group and 3 of 4 dentifrices already on the market.

Abstract
Context: The absence of a protocol for the treatment of halitosis has led us to compare mouthrinses with mechanical oral hygiene procedures for treating morning breath by employing a hand-held sulfide monitor. Aims: To compare the efficacy of five modalities of treatment for controlling morning halitosis in subjects with no dental or periodontal disease. Settings and Design: This is a five-period, randomized, crossover clinical trial. Materials and Methods: Twenty volunteers were randomly assigned to the trial. Testing involved the use of a conventional tongue scraper, a tongue scraper joined to the back of a toothbrush's head, two mouthrinses (0.05% cetylpyridinium chloride and 0.12% chlorhexidine digluconate) and a soft-bristled toothbrush and fluoride toothpaste for practicing oral hygiene. Statistical Analysis Used: Data analysis was performed using SPSS version 17 for Windows and NCSS 2007 software (P < 0.05). The products and the periods were compared with each other using the Friedman's test. When significant differences (P < 0.05) were determined, the products and periods were compared in pairs by using the Wilcoxon's test and by adjusting the original significance level (0.05) for multiple comparisons by using the Bonferroni's method. Results: The toothbrush's tongue scraper was able to significantly reduce bad breath for up to 2 h. Chlorhexidine reduced bad breath only at the end of the second hour, an effect that lasted for 3 h. Conclusions: Mechanical tongue cleaning was able to immediately reduce bad breath for a short period, whereas chlorhexidine and mechanical oral hygiene reduced bad breath for longer periods, achieving the best results against morning breath.

Abstract
This study aimed to: (1) determine concordance rates of self-reported and subjectively determined indicators of oral malodor in twins; (2) determine the relative contributions of genetic and environmental factors to levels of volatile sulfur compounds (VSCs) in intraoral and exhaled breath. Fifty-one twin pairs participated in the study. Measurements of VSCs were obtained by a halimeter. The presence of tongue coatings was determined and twins filled out a 32-item questionnaire on oral malodor indicators independently of one another. Estimates of heritability (h2) for halimeter measurements were computed by SOLAR. The concordance rates for the presence of tongue coating among identical and fraternal twins were 67% and 11%, respectively. In the 10 most informative items, 70% exhibited higher concordance rates for identical than for fraternal twins. Of particular interest were the differences in concordance rates for dry mouth, sinus infection and unusual sweating. The h2 for intraoral breath was 0.28 +/- 0.17 (NS), whereas the h2 for exhaled breath was 0.50 +/- 0.20 (p = .0207). The concordance rates of tongue coatings and malodor indicators were higher in identical twins than in fraternal twins. Intraoral breath VSC values were primarily attributable to environmental factors, whereas exhaled breath VSC values were partially explained by genetic factors.

Abstract
Background: Various mouth rinses have been used in the treatment of halitosis, but most of the evidence for the efficacy of mouth rinses is anecdotal. In the present study, 0.2% chlorhexidine rinse and an essential oil mouth rinse are compared for their efficacy in reducing the breath mercaptan levels. Materials and Methods: Fifteen patients with the chief complaint of oral malodor were randomly divided into 3 groups and were provided with the respective mouth rinses. Pre rinsing measurements were performed on the Day 1 and no other periodontal treatment was instituted. Post rinsing estimation of mercaptan levels was performed after 7 days. Results: When comparing chlorhexidine with the essential oil mouth rinse, the reduction in VSCs was highly significant in the chlorhexidine group (P<0.01). However, the reduction in the organoleptic scores was not significant among the two groups. Organoleptic scores showed very highly significant correlations with the VSC concentrations measured by the spectrophotometric method. Conclusion: The spectrophotometric technique employed in this study appears to be a promising new method for evaluation of oral malodor. Chlorhexidine still appears to be the agent of choice as a short term regimen in cases of oral malodor.

Abstract
OBJECTIVE To determine whether there is a correlation between halitosis and mouth breathing in children. STUDY DESIGN Fifty-five children between 3 and 14 years of age were divided into two groups (nasal and mouth breathing) for the assessment of halitosis. A descriptive analysis was conducted on the degree of halitosis in each group. The chi-square test was used for comparison between groups, with a 5% level of significance. RESULTS There was a significantly greater number of boys with the mouth-breathing pattern than girls. A total of 23.6% of the participants had no mouth odor, 12.7% had mild odor, 12.7% had moderate odor and 50.9% had strong odor. There was a statistically significant association between halitosis and mouth breathing. CONCLUSIONS The occurrence of halitosis was high among the children evaluated, and there was a statistically significant association between halitosis and mouth breathing.

Abstract
OBJECTIVES This work reviews the current knowledge of aetiology and measurement methods of halitosis. DATA Halitosis is an unpleasant or offensive odour emanating from the breath. The condition is multifactorial and may involve both oral and non-oral conditions. SOURCES A private, monthly with keywords halitosis, malodo(u)r, (a)etiology, measurement, and management from Medline and Pubmed updated database of literature was reviewed. CONCLUSIONS In approximately 80-90% of all cases, halitosis is caused by oral conditions, defined as oral malodour. Oral malodour results from tongue coating, periodontal disease, peri-implant disease, deep carious lesions, exposed necrotic tooth pulps, pericoronitis, mucosal ulcerations, healing (mucosal) wounds, impacted food or debris, imperfect dental restorations, unclean dentures, and factors causing decreased salivary flow rate. The basic process is microbial degradation of organic substrates. Non-oral aetiologies of halitosis include disturbances of the upper and lower respiratory tract, disorders of the gastrointestinal tract, some systemic diseases, metabolic disorders, medications, and carcinomas. Stressful situations are predisposing factors. There are three primary measurement methods of halitosis. Organoleptic measurement and gas chromatography are very reliable, but not very easily clinically implemented methods. The use of organoleptic measurement is suggested as the 'gold standard'. Gas chromatography is the preferable method if precise measurements of specific gases are required. Sulphide monitoring is an easily used method, but has the limitation that important odours are not detected. The scientific and practical value of additional or alternative measurement methods, such as BANA test, chemical sensors, salivary incubation test, quantifying beta-galactosidase activity, ammonia monitoring, ninhydrin method, and polymerase chain reaction, has to be established.
