Assessment of the Quality and Readability of Web-Based Arabic Health Information on Halitosis: Infodemiological Study.

BACKGROUND: Halitosis, characterized by an undesirable mouth odor, represents a common concern. OBJECTIVE: This study aims to assess the quality and readability of web-based Arabic health information on halitosis as the internet is becoming a prominent global source of medical information. METHODS: A total of 300 Arabic websites were retrieved from Google using 3 commonly used phrases for halitosis in Arabic. The quality of the websites was assessed using benchmark criteria established by the Journal of the American Medical Association, the DISCERN tool, and the presence of the Health on the Net Foundation Code of Conduct (HONcode). The assessment of readability (Flesch Reading Ease [FRE], Simple Measure of Gobbledygook, and Flesch-Kincaid Grade Level [FKGL]) was conducted using web-based readability indexes. RESULTS: A total of 127 websites were examined. Regarding quality assessment, 87.4% (n=111) of websites failed to fulfill any Journal of the American Medical Association requirements, highlighting a lack of authorship (authors' contributions), attribution (references), disclosure (sponsorship), and currency (publication date). The DISCERN tool had a mean score of 34.55 (SD 7.46), with the majority (n=72, 56.6%) rated as moderate quality, 43.3% (n=55) as having a low score, and none receiving a high DISCERN score, indicating a general inadequacy in providing quality health information to make decisions and treatment choices. No website had HONcode certification, emphasizing the concern over the credibility and trustworthiness of these resources. Regarding readability assessment, Arabic halitosis websites had high readability scores, with 90.5% (n=115) receiving an FRE score ≥80, 98.4% (n=125) receiving a Simple Measure of Gobbledygook score <7, and 67.7% (n=86) receiving an FKGL score <7. There were significant correlations between the DISCERN scores and the quantity of words (P<.001) and sentences (P<.001) on the websites. Additionally, there was a significant relationship (P<.001) between the number of sentences and FKGL and FRE scores. CONCLUSIONS: While readability was found to be very good, indicating that the information is accessible to the public, the quality of Arabic halitosis websites was poor, reflecting a significant gap in providing reliable and comprehensive health information. This highlights the need for improving the availability of high-quality materials to ensure Arabic-speaking populations have access to reliable information about halitosis and its treatment options, tying quality and availability together as critical for effective health communication.

The association between halitosis and periodontitis: a systematic review and meta-analysis.

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.

[Halitosis. Multidisciplinary approach]. / Khalitoz ­ mezhdistsiplinarnaya problema.

Halitosis is a common complaint among patients. Up to 50% of people worldwide claim to have persistent or intermittent bad breath. Often, bad breath not only disrupts the social life of patients, but is also a symptom of systemic diseases. An important step in the treatment of halitosis is the localization of the source and possible cause of the unpleasant smell. Most often, the problem of halitosis is solved by dentists, because intraoral halitosis accounts for up to 90% of all cases, but doctors of many specialties should deal with the differential diagnosis of its causes. This article considers the main causes of halitosis in patients with diseases of various organ systems.

Effectiveness of lasers and aPDT in elimination of intraoral halitosis: a systematic review based on clinical trials.

In recent years, there has been increasing interest in research showing positive results in antimicrobial photodynamic therapy (aPDT) and laser therapy (LT) in dentistry. The authors of this review tried to answer the question: "Is the effectiveness of lasers and aPDT in the elimination of intraoral halitosis possible?" For this purpose, the electronic database of PubMed and Cochrane Library were searched until September 2021 using a combination of different keywords: (bad breath OR fetor ex ore OR halitosis OR oral malodor) AND (laser OR PDT OR PACT OR photodynamic inactivation OR photodynamic therapy OR photodynamic antimicrobial chemotherapy). Initially, 83 studies were identified. A total of 9 articles were qualified after the application of the eligibility criteria. Eight works concerned aPDT treatment, and only one dedicated to the Er,Cr:YSGG laser. A significant reduction in halitosis occurred immediately after both LT and aPDT. The review found the confirmation of the effectiveness of laser therapy in reducing the number of volatile sulfur compounds (VSC) and the amount of anaerobic bacteria responsible for VSC formation. In most studies, a positive effect was observed for a 1-week follow-up. Laser therapy (aPDT, Er,Cr:YSGG) effectively eliminates microorganisms that produce volatile compounds and can effectively eliminate bad breath for the longer period of time than traditional methods of combatting this ailment.

Prevalence of halitosis among young adults in Dunedin, New Zealand.

OBJECTIVES: To investigate the prevalence of halitosis in young adults. METHODS: Young adults (n = 372; mean age = 21.0 ± 2.6 years old, range = 18-30 years) in Dunedin, New Zealand, were recruited into the cross sectional study after providing informed consent. The prevalence of halitosis was determined using both objective measurements (parts per billion [ppb] volatile sulphur compounds [VSCs] in the exhaled air) and subjective measurements (self-reported halitosis questionnaire, tongue coating index, and organoleptic assessment). RESULTS: Volatile sulphur compounds measurements indicated that the prevalence of halitosis (values ≥140 ppb) was 31.2%; 25.6% of participants self-reported halitosis. The organoleptic assessment revealed that 14.3% of the participants had a score of ≥2. A positive correlation was found between the VSC measurements and organoleptic assessment (p < 0.05). No significant relationship was found between self-reported halitosis and either organoleptic assessment or VSC measurements. Self-reported dry mouth, smoking, oral hygiene index, DMFT index, and tongue coating score were significantly associated with the organoleptic assessment (p < 0.05). The self-reported dry mouth, mouth breathing and tongue coating score were significantly associated with the VSC scores (p < 0.05). CONCLUSION: Halitosis, as represented by VSC, was found in 31.2% of the participants. VSC scores and organoleptic assessment were positively correlated. There was no significant relationship between self-reported halitosis and either organoleptic assessment or VSC measurements.

Clinical and self-reported oral conditions and quality of life in the 1982 Pelotas birth cohort.

AIM: To investigate and compare the effects of clinical and self-perceived oral conditions on oral health-related quality of life (OHRQoL) among young adults. MATERIALS AND METHODS: Adults enrolled in the 1982 Pelotas birth cohort were included in this study. OHRQoL was assessed by the Oral Health Impact Profile-14 (OHIP-14) instrument. Clinical parameters such as dental caries, periodontitis, aesthetics, and occlusal characteristics, and tongue coating were collected through clinical evaluation, while dental anxiety and halitosis were self-reported. Direct and indirect effects of clinical and self-perceived oral conditions on OHRQoL were assessed using structural equation modelling. RESULTS: Five-hundred and thirty-nine individuals participated in this study. Dental caries (ß = 0.12) and periodontitis (ß = 0.11) were directly and indirectly (via halitosis, ß = 0.05 for periodontitis only) associated with greater OHIP-14 scores, while the other clinical conditions did not influence the OHIP-14 scores. Dental anxiety and halitosis were also associated with higher OHIP-14 scores (ß = 0.31 and ß = 0.27, respectively). CONCLUSIONS: This study found a positive association between clinically diagnosed and self-reported oral conditions and OHRQoL; however, the self-reported conditions had a higher impact on OHRQoL.

The association between halitosis and oral-health-related quality of life: A systematic review and meta-analysis.

AIM: To investigate whether halitosis is associated with impaired oral-health-related quality of life (OHRQoL). MATERIALS AND METHODS: This is a systematic review of the literature. Electronic searches were performed in PubMed via Medline, Web of Science, Scopus, and EMBASE up to and including June 2021. Observational studies that assessed halitosis in association with OHRQoL were included. The pooled standardized mean difference (SMD) was estimated by meta-analysis. RESULTS: Thirteen studies were included in the review; however, the meta-analysis included only 10 studies, all cross-sectional, comprising 2692 individuals. The overall meta-analysis showed an association between halitosis and impaired OHRQoL (SMD 0.51; 95% confidence interval 0.27-0.75). Subgroup analyses, however, indicated that this association remained only among adults. Neither the OHRQoL instrument nor the halitosis assessment method, or the cultural background, influenced the pooled estimates. Meta-regression analyses revealed that the OHRQoL instrument, the halitosis assessment method, and the sample composition did not explain the between-study heterogeneity. Methodological quality appeared to explain 20% of the overall heterogeneity, as studies with high risk of bias overestimated the magnitude of the association. CONCLUSION: Our findings suggest that halitosis is associated with impaired OHRQoL.

Periodontitis and self-reported halitosis among young adults from the 1982 Pelotas Birth Cohort.

OBJECTIVE: To investigate the association between periodontitis and self-reported halitosis among young adults, and whether there is an interaction between the effects of smoking and periodontitis on halitosis. METHODS: Data from the 1982 Pelotas birth cohort, Brazil, were used. The controlled direct effect of periodontitis on self-reported halitosis, not mediated by tongue coating, was estimated using marginal structural modeling. In addition, an interaction between the effects of smoking and periodontitis on halitosis was also tested. Confounders comprised sociodemographic information, obesity, diabetes, and oral hygiene habits. RESULTS: The controlled direct effect of periodontitis on halitosis not mediated by tongue coating showed that individuals with periodontitis had 90% higher risk of self-reporting halitosis (RR 1.90) compared to healthy individuals. Individuals with mild periodontitis had twice the risk of reporting halitosis than periodontally healthy individuals (RR 2.31). We also found an interaction between the effects of smoking and periodontitis on halitosis, as noted among smokers with mild (RR 2.91) and moderate-to-severe periodontitis (RR 5.84). CONCLUSION: There is a controlled direct effect of periodontitis on halitosis not mediated by tongue coating. Additionally, an interaction between the effects of smoking and periodontitis on halitosis was also detected.

The OralChromaTM CHM-2: a comparison with the OralChromaTM CHM-1.

OBJECTIVES: Already decades ago, the diagnosis of halitosis was facilitated with the arrival of chair-side instruments to score the breath odor. These devices are used for a more objective assessment of halitosis compared with organoleptic scoring, but these too have their disadvantages. To overcome some of the drawbacks of the original model of the OralChromaTM (CHM-1), few years ago a second generation of this machine (CHM-2) was introduced. This study compared both devices in a clinical setting. MATERIALS AND METHODS: All records of the patients visiting a specialized halitosis consultation over a period of 5 years (2012-2017) were examined. The correlations of the OralChromaTM CHM-1 and CHM-2 with the organoleptic and Halimeter® measurements were analyzed. Additionally the sensitivity, specificity, and negative and positive predicted values were calculated. RESULTS: A total of 581 data points were included (CHM-1: 292, CHM-2: 289). The correlations between both models with the organoleptic measurements were not statistically significant different. The CHM-2 seemed superior to the CHM-1 in the quantification of dimethyl sulfide with a detection rate of 95% and 61%, respectively. Additionally, the CHM-2 was significantly more sensitive for dimethyl sulfide than the CHM-1. However the latter showed in turn a better sensitivity for hydrogen sulfide and methyl mercaptan. CONCLUSION: The CHM-2 showed a better sensitivity for dimethyl sulfide than its predecessor. However, its sensitivity for hydrogen sulfide and methyl mercaptan was worse. CLINICAL RELEVANCE: Dimethyl sulfide is the main volatile implicated in extra-oral blood-borne halitosis, this makes the OralChromaTM CHM-2 the instrument of choice when this is suspected.

Halitosis: Helicobacter pylori or oral factors.

INTRODUCTION: Halitosis is a common complaint among people which has various socioeconomic effects. The prevalence of halitosis includes a variety of 22% up to 50% in different societies. According to studies, there have been reports of remarkable improvements in halitosis after Helicobacter pylori eradication treatment. In studies on the relationship between H. Pylori and halitosis, the role of oral factors as the most important cause of halitosis has been neglected. This study was conducted with the aim of investigating the effect of oral factors on halitosis in patients with H. Pylori. MATERIALS AND METHODS: A total of 100 dyspeptic patients who had H. pylori-positive serologic test were examined by an organoleptic method for the presence of halitosis. DMFT index was used in order to record the dental status. Oral hygiene was evaluated using the simplified oral hygiene index (OHI-S). RESULTS: The mean DMFT index was 9.09 ± 3.97. The score of simplified oral hygiene index was 1.79 ± 0.949. There was a direct and significant relationship between halitosis with DMFT, OHI-S (P < 0.01). There was no significant relationship between halitosis and coated tongue (P > 0.01). CONCLUSIONS: According to the results of this study, there is a relation between oral factors and halitosis in patients with positive H. pylori test. Due to the lower level of all these indices in patients with halitosis, we cannot attribute halitosis in patients with H. pylori infection to the presence of this microorganism with certainty.

Estimated prevalence of halitosis: a systematic review and meta-regression analysis.

OBJECTIVE: This study aims to conduct a systematic review to determine the prevalence of halitosis in adolescents and adults. METHODS: Electronic searches were performed using four different databases without restrictions: PubMed, Scopus, Web of Science, and SciELO. Population-based observational studies that provided data about the prevalence of halitosis in adolescents and adults were included. Additionally, meta-analyses, meta-regression, and sensitivity analyses were conducted to synthesize the evidence. RESULTS: A total of 584 articles were initially found and considered for title and abstract evaluation. Thirteen articles met inclusion criteria. The combined prevalence of halitosis was found to be 31.8% (95% CI 24.6-39.0%). Methodological aspects such as the year of publication and the socioeconomic status of the country where the study was conducted seemed to influence the prevalence of halitosis. CONCLUSIONS: Our results demonstrated that the estimated prevalence of halitosis was 31.8%, with high heterogeneity between studies. The results suggest a worldwide trend towards a rise in halitosis prevalence. CLINICAL RELEVANCE: Given the high prevalence of halitosis and its complex etiology, dental professionals should be aware of their roles in halitosis prevention and treatment.

The effect of professional tooth cleaning or non-surgical periodontal therapy on oral halitosis in patients with periodontal diseases. A systematic review.

OBJECTIVE: The aim of this systematic review was to give the best available evidence on the impact of professional tooth cleaning (PTC) and scaling and root planing (SRP) on oral halitosis in patients with periodontal diseases. MATERIAL AND METHODS: Three databases were screened for relevant studies. Only randomized controlled trials (RCTs) or controlled clinical trials (CCT) were included. The primary outcome in all included studies was volatile sulphur compounds (VSC) measured by Halimeter or OralChroma and organoleptic scores as secondary outcome. Only studies investigating healthy adults except for periodontitis or gingivitis were included. The considered intervention strategies were professional tooth cleaning and non-surgical periodontal treatment. For both strategies, additional oral hygiene instructions (OHI) were possible. Two independent reviewers performed the study selection and quality assessment. SEARCH RESULTS: After abstract and title screening and subsequent full-text reading of potential papers, a placebo-controlled RCT could not be found. However, eight studies or particular arms used PTC or SRP as sole interventions and were included in this review. All trials or study arms included showed a positive effect on VSC levels or organoleptic scores after intervention. CONCLUSIONS: Based on best available evidence, PTC and SRP in combination with oral hygiene instructions reduced VSC values in patients with oral halitosis and/or periodontal diseases, independent of tongue cleaning and the use of mouth rinses.

Is periodontitis associated with halitosis? A systematic review and meta-regression analysis.

AIM: To systematically review the literature in order to investigate a potential association between periodontitis and halitosis. METHODS: Electronic searches were performed in four different databases: PubMed, Scopus, Web of Science and Scielo. Population-based observational studies that tested the association between periodontitis and halitosis were included. Additionally, meta-analysis, meta-regression and subgroup analyses were performed to synthesize the evidence. RESULTS: A total of 1,107 articles were identified in electronic searches; out of which, five were included within the meta-analysis. Pooled estimates revealed that individuals with periodontitis presented 3.16 times higher odds (OR 3.16; 95% CI: 1.12-8.95) of having halitosis. Meta-regression and subgroups analyses showed that criteria used for halitosis and periodontitis assessment explained nearly 45% and 24% of heterogeneity between studies, respectively. CONCLUSIONS: Positive association between periodontitis and halitosis was found in pooled results of population-based observational studies. However, this evidence is derived from cross-sectional studies.

The long-term effect of a zinc acetate and chlorhexidine diacetate containing mouth rinse on intra-oral halitosis-A randomized clinical trial.

AIM: To evaluate the long-term effects of a zinc acetate and chlorhexidine diacetate mouth rinse (Zn/CHX) on intra-oral halitosis. MATERIALS AND METHODS: Forty-six adults with intra-oral halitosis were randomized into a 6-month, double-blind, placebo-controlled clinical study. The presence of intra-oral halitosis was evaluated at baseline, 3 and 6 months after treatment by assessment of organoleptic score (OLS) and by total volatile sulphur compounds (T-VSC), hydrogen sulphide (H2 S) and methyl mercaptan (MM) concentrations in exhaled air. RESULTS: A Zn/CHX mouth rinse provided significantly better control of intra-oral halitosis than a placebo mouth rinse. At 3 and 6 months, individuals rinsing with the Zn/CHX rinse presented with reductions of the OLS, T-VSC (p < .01, respectively), H2 S (p < .001), and MM (p < .01) in subjects' exhaled air. At 6 months, 68.2% of individuals using the Zn/CHX rinse experienced a 1 or 2 category improvement in OLS compared with 19.1% of placebo-treated subjects. 91% of subjects in the Zn/CHX group were categorized as being effectively treated for intra-oral halitosis (i.e. H2 S < 112 ppb), compared to 43% in the placebo group. CONCLUSION: Zn/CHX mouth rinse provides effective long-term efficacy against intra-oral halitosis, assessed both objectively and subjectively. With regular rinsing, the effect was sustained for 6 months.

The effect of periodontal therapy on intra-oral halitosis: a case series.

AIM: The aim of this study was to evaluate the effects of non-surgical periodontal therapy on intra-oral halitosis 3 months after therapy. MATERIAL AND METHODS: Sixty-eight adults with intra-oral halitosis were included in a case series. Intra-oral halitosis was evaluated at baseline, and at 3 months after treatment using the organoleptic scores (OLS), Halimeter® , and a gas chromatograph. RESULTS: Significant reductions for OLS (p < 0.01), total sum of volatile sulphur compounds (T-VSC) (p < 0.01) and methyl mercaptan (MM) (p < 0.05) values were found after treatment. Hydrogen sulphide (H2 S) levels were not significantly reduced. The numbers of probing pockets 4 mm, 5 mm and 6 mm were significantly reduced as a result of therapy (p < 0.001). Bleeding on probing (BOP) and plaque indices were also significantly reduced (p < 0.001). For the 34 individuals with successful periodontal treatment (BOP<20% and a ≥50% reduction of total pocket depth) reductions in OLS (p < 0.01) and T-VSC scores (p < 0.01) were found. Eleven individuals were considered effectively treated for intra-oral halitosis presenting with a T-VSC value <160 ppb, a H2 S value <112 ppb and a MM value <26 ppb. CONCLUSION: Non-surgical periodontal therapy resulted in reduction of OLS, MM and T-VSC values 3 months after therapy. Few individuals were considered as effectively treated for intra-oral halitosis.

The effect of different mouth rinse products on intra-oral halitosis.

AIM: To evaluate the effect of different mouth rinses 12 h after rinsing on genuine intra-oral halitosis. MATERIALS AND METHODS: Twenty-four adults with halitosis were included in a double-blind, crossover, randomized clinical trial. Halitosis was evaluated 12 h after rinsing with placebo and five mouth rinse products containing zinc acetate and chlorhexidine diacetate; zinc lactate, chlorhexidine and cetylpyridinium chloride; zinc acetate and chlorhexidine diacetate with reduced amounts of mint and menthol; zinc chloride and essential oil; and chlorine dioxide using the organoleptic method and a gas chromatograph. Test periods were separated by 1 week. RESULTS: Hydrogen sulphide (H2 S), methyl mercaptan (MM) and the organoleptic scores (OLS) were significantly reduced 12 h following rinsing with all substances compared to placebo (P < 0.05). H2 S was more effectively reduced after rinsing with zinc acetate and chlorhexidine diacetate and zinc acetate and chlorhexidine diacetate with reduced amounts of mint and menthol compared to rinsing with zinc chloride and essential oil (P < 0.05), and significantly lower values of MM were obtained after rinsing with zinc acetate and chlorhexidine diacetate compared to zinc lactate, chlorhexidine and cetylpyridinium chloride (P < 0.05). The percentage effectively treated individuals (H2 S (<112 ppb), MM (<26 ppb) and OLS score <2) varied from 58% percentage (zinc acetate and chlorhexidine diacetate) to 26% (zinc chloride and essential oil). CONCLUSION: All treatments resulted in reduction in halitosis 12 h after rinsing compared to placebo. H2 S and MM were most effectively reduced by zinc acetate and chlorhexidine diacetate.

The effect of water on morning bad breath: a randomized clinical trial.

OBJECTIVES: To assess the effects of water on the parameters of 'morning bad breath' (MBB) and to evaluate whether there is a difference between rinsing with water and drinking a glass of water. MATERIALS AND METHODS: A total of 50 participants were recruited and were randomly divided into two equal groups. One group rinsed with 15 ml of water for 30 s, and another group drank 200 ml of water within 30 s. Clinical assessments were carried out during one visit between 7:30 am and 12:00 pm. Pre- and post-intervention measures were assessed organoleptically as primary outcome parameters, and a secondary outcome parameter was assessed using both the Halimeter(®) and OralChroma(™) apparatuses to evaluate volatile sulphur compounds (VSCs), hydrogen sulphide (H2 S), methyl mercaptan (CH3 SH) and dimethyl sulphide ((CH3 )2 S). In addition, the presence of tongue coating (discoloration/thickness) and tongue fissures was assessed. RESULTS: All 50 participants completed the study. In both groups, a significant reduction in the organoleptic score and the OralChroma(™) H2 S and CH3 SH readings was obtained after the intervention. Both regimens resulted in a CH3 SH reduction of approximately 60%, whereas the reduction in H2 S was between 30% and 50%. The acceptable change between pre- and post-assessments of the clinical parameters was not significantly different between the drinking and rinsing groups. CONCLUSION: Rinsing with water or drinking a glass of water had a statistically significant effect on the MBB parameters. No significant difference was obtained between the two regimens.

Treatment of oral malodour. Medium-term efficacy of mechanical and/or chemical agents: a systematic review.

FOCUSED QUESTION: What is the effect of a dentifrice (DF), a mouthwash (MW), tongue cleaning (TC), or any combination of these as adjunct to toothbrushing on intra-oral malodour and tongue coating as compared to toothbrushing alone in systemically healthy patients, when used for a minimum follow-up period of 2 weeks? MATERIAL AND METHODS: The MEDLINE-PubMed, Cochrane-CENTRAL and EMBASE databases were searched up to August 2014. Measurements of Volatile Sulphur Compounds and organoleptic scores of oral malodour were selected as outcome variables. Data were extracted and a descriptive analysis was performed. RESULTS: Independent screening of 1054 unique papers resulted in 12 eligible clinical trials with a medium-term (≥2 weeks) duration. The majority of studies provided a significant reduction in oral malodour when evaluating products with an active ingredient (incorporated into a DF or a MW) used adjunctively to toothbrushing. The added value of tongue cleaning over a MW was evaluated in one study. CONCLUSION: Due to very limited evidence, the potential effect of a specifically formulated dentifrice, a mouthwash or a tongue scraper for treating oral malodour is, in general, unclear. For mouthwashes containing the active ingredients chlorhexidine + cetylpyridinium chloride + zinc (CHX + CPC + Zn) and zinc chloride + cetylpyridinium chloride (ZnCl + CPC) most evidence was available. The strength of a recommendation to use these products was graded to be 'weak'.

Multi-Sensor Approach for the Monitoring of Halitosis Treatment via Lactobacillus brevis (CD2)-Containing Lozenges--A Randomized, Double-Blind Placebo-Controlled Clinical Trial.

The aim of this randomized clinical trial was to evaluate whether a recently described multi-sensor approach called BIONOTE(®) is accurate enough to verify the efficacy of treatment of patients with halitosis. A treatment with Lactobacillus brevis (CD2)-containing lozenges, compared with placebo was tested. The BIONOTE(®) was compared with traditional techniques used to detect halitosis: OralChroma™ and two calibrated odor judges enrolled for the organoleptic assessments. Twenty patients (10 treated and 10 placebo), suffering from active phase halitosis were included in the study. Treatment consisted of Lactobacillus brevis (CD2)-containing lozenges or placebo, 4 tablets/day for 14 days. t0 was before the beginning of the study; t1 was day 7 and t2 was day 14. The effectiveness of treatment was assessed through: (1) Rosenberg score; (2) Winkel tongue coating index (WTCI) anterior and posterior; (2) OralChroma™; (3) the new developed multi-sensor approach, called BIONOTE(®) (test technique). Only the WTCI anterior revealed statistically significant changes between t0 and t2 data (p = 0.014) in the treated group. Except for the WTCI anterior, all diagnostic methods revealed the lack of effectiveness for halitosis of a 14-days treatment with Lactobacillus brevis (CD2)-containing lozenges. The BIONOTE(®) multisensor system seems accurate in addition to OralChroma™ to assess the initial condition of halitosis and its mitigation during treatment.
