Abstract
BACKGROUND Halitosis in children implies psychosocial repercussions. Risk factors associated with this condition are unclear, and detection methods are inaccurate. AIM To quantify the levels of sulfur-like compounds in children with asthma and healthy children from a novel validated assay, and to establish the risk factors related to halitosis. DESIGN One hundred and twenty-eight individuals (63 healthy and 65 asthmatic) from 3 to 17 years of age were tested using a passive colorimetric sensor to measure the levels of sulfur-like compounds in breath and saliva. Information was collected on oral hygiene habits, gingival and dental health, breathing type, and dental malocclusion. RESULTS The mean values of hydrogen sulfide were 4.0 ± 6.8 and 19.7 ± 12.2 ppbv (parts per billion in volume) in the control and asthmatic groups, respectively (p < .001). The presence of higher concentrations of sulfur compounds was significantly associated (p < .05) with the presence of gingival inflammation, tongue coating, dental plaque, mouth breathing, hypomineralization, age, tongue brushing, and the use of dental floss. CONCLUSION The level of sulfur in breath and saliva was significantly higher in patients with asthma. These results can serve as a precedent to raise awareness among paediatricians and parents about oral hygiene care in children and adolescents.

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
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
BACKGROUND Research indicates that adolescents may have difficulties to adopt the tooth brushing recommendations delivered in prophylaxis programs. However, it is not clear whether these difficulties are seen amongst the entire age range of adolescence (10-19 years) or only occur at certain developmental stages of the adolescence. The present study analyzes the tooth brushing performance of adolescents and compares it to the best-practice of tooth brushing demonstrated during prophylaxis programs. METHODS A random sample of N = 66 adolescents, comprising 10-year-olds (n = 42) and 15-year-olds (n = 24), were asked to perform oral hygiene to the best of their abilities in front of a tablet camera. Videos were analyzed for tooth brushing duration, location, and brushing movements, and the difference between the actual and expected behaviour was tested for consistency using repeated measures ANOVAs and Student's t-tests. For the direct comparison across different age groups, already available data from 12- and 18-year-olds were reanalysed. RESULTS The average brushing time (mean ± SD) of the 10-year-olds and 15-year-olds was 195.8 s (74.6 s) and 196.1 s (75.8 s), respectively. Regardless of age, the adolescents distributed their brushing time unevenly across the inner, outer and occlusal surfaces. The inner surfaces in particular were neglected to a considerable extent, as no age group spent more than 15.8% of the total brushing time on them. Furthermore, all age groups showed a high proportion of horizontal movements on the inner and outer surfaces, regardless of the movements instructed for the respective surfaces. CONCLUSION Even if adolescents brush to the best of their abilities, they neglect or skip one or many of the tooth surfaces. The reasons for the lack of compliance to tooth brushing instructions are discussed in light of the methods used in prophylaxis programs and the influence of parents.

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
Introduction Halitosis as a common dental problem results in psychological social problems and relates to many factors. The aim of this study was to evaluate the prevalence of halitosis and its associated factors among students aged from 14 to 18 years in Kermanshah in 2015. Materials and methods The study was conducted in high school students of Kermanshah city in 2015. The questionnaire including questions about bad breath and other associated factors (demographic information, background diseases, oral and dental problems, decay-missing-filled (DMF) index, etc.) was completed by students or determined by the examiner. Organoleptic evaluation was conducted. Prevalence of organoleptic and self-reported halitosis and related factors was reported. The relationship between malodor and variables was evaluated and the most important factor was determined by multiple logistic regression analysis. The diagnostic agreement between self-perception and organoleptic halitosis was assessed using Kappa coefficient as well. Results The prevalence of halitosis in the organoleptic evaluation was 29.75% and higher in boys (32.6% male vs. 25.2% female) and 27.47% in self-perception (32.9% male vs. 19% female). The diagnostic agreement between organoleptic and self-perception halitosis was moderate or poor. Among the studied factors, the most important factor related to the organoleptic evaluation of halitosis was DMF≥4 (P<0.001 and OR=2.253). Conclusion The DMF index was the factor most strongly associated with organoleptic halitosis in this sample of high school students. Other factors with significant association included parent's lower education level, not brushing, not flossing, bleeding gums, tongue coating, pericoronitis, and plaque index. Also, older age, male gender, and gastrointestinal disease increased the possibility for halitosis.

Abstract
BACKGROUND: Smoking is associated with various systemic conditions and contributes to a huge financial burden to economies around the world. AIM: The study aimed to evaluate global data about the prevalence of tobacco use among male and female adolescents and to discuss smoking-related oral complications. METHODS: The prevalence data of tobacco use among adolescents (13-15 years) was retrieved from the World Health Organization (Global Health Observatory). The World Bank’s statistics about gross national income (GNI) per capita were used to categorise low-income, lower-middle-income, upper-middle-income, and high-income countries. PubMed, Web of Science, Scopus, and Embase databases were searched to gather updated evidence about the adverse consequences of smoking on oral health among adolescents. RESULTS: The prevalence of tobacco use was 19.33%, and there were 23.29% of male and 15.35% female smoker adolescents in 133 countries (p < 0.001). The highest prevalence of tobacco use in male (24.76%) and female (19.4) adolescents was found in high-income countries. Significantly higher proportions of male adolescents were smokers than female counterparts in low-income, lower-middle-income, and upper-middle-income (p < 0.001). However, there were no statistically significant differences in tobacco use between male and female adolescents in high-income countries. Low-income countries had the lowest prevalence (14.95%) of tobacco use, while high-income countries had the highest prevalence estimates (22.08). Gingivitis (72.8%), gingival bleeding (51.2%), oral malodor or halitosis (39.6%) is common oral conditions among smoker adolescents. Smoking habit is significantly associated with dental caries, periodontal disease, hairy tongue, smoking-related melanosis, and hyperkeratosis among adolescents. CONCLUSION: There was a high prevalence of tobacco use among male and female adolescents around the globe. Available evidence suggests a strong association between smoking and compromised oral health among adolescents. Globally, measures should be taken to prevent and control the menace of tobacco use to reduce systemic and oral complications.

Abstract
Objective To evaluate the prevalence of halitosis and the factors associated with it among dental students and interns in Lahore, Pakistan. Methods A cross-sectional study design was chosen, and a sample of dental students and interns was collected from seven dental colleges in Lahore, Pakistan. A total of 833 participants were approached in person as convenient sample population. A self-reported questionnaire was administered and informed consent was obtained. The associations between oral malodor and different variables of the study were explored using analytical statistics (Chi-square test and logistic regression analysis). Statistical significance was determined using a 95% confidence interval (CI). Results Six hundred and fifteen participants (aged 19-27 years) completed the survey with a response rate of 73.8%. The prevalence of self-reported halitosis was 75.1%. More female (51.4%) than male students (23.7%) reported oral malodor, and most participants (61%) reported early morning halitosis. Thirteen percent of respondents had examination for oral malodor by a dentist and 37.6% treated the condition with self-medication. Binary logistic regression model showed that male gender (odds ratio [OR] =0.44, CI = 0.22-0.87), daily use of dental floss (OR = 0.28, CI = 0.13-0.58), and drinking tea with mint (OR = 0.44, CI = 0.22-0.89) were significantly associated with oral malodor. The participants with tongue coating had higher odds (OR = 2.75, CI = 1.13-6.69) of having oral malodor than those without tongue coating, and the association was statistically significant. Conclusions The study identified high prevalence of oral malodor among dental students and interns. They should receive appropriate diagnosis and management of the condition from dentist. The regular use of dental floss and removal of tongue coating can significantly reduce halitosis.

Abstract
Objective To examine: (I) the current evidence of the impact of fixed orthodontic appliances on the development of halitosis in patients undergoing orthodontic treatment, and (II) the influence of different orthodontic bracket systems on halitosis. Material and methods Three electronic databases (PubMed, Scopus, and Cochrane Library) were searched prior to March 15, 2018. The review was systematically conducted and reported according to the Cochrane Handbook and the PRISMA statement. Only Randomised Clinical Trials (RCTs) were considered. Selected full-text papers were independently assessed by four investigators and any disagreements were resolved by consensus. The Cochrane Handbook was used to grade the risk of bias and the quality of evidence was rated according to GRADE. Results Out of 363 identified studies, three RCTs on halitosis and fixed orthodontic appliances met the inclusion criteria. The risk of bias in the three studies was rated as high and the quality of evidence was rated as very low. Conclusions/clinical implications There is a lack of scientific evidence that subjects with fixed orthodontic appliances develop halitosis during treatment. Additional well-conducted RCTs with extended periods of assessment are needed as well as consensus concerning cut-off values for the diagnosis of halitosis.

Abstract
Background Many countries offer systematic group prevention programs in kindergarten and school in order to promote children’s oral health. Little is known, however, about the actual toothbrushing abilities of children when group prevention programs end. Methods In Germany, all children take advantage from a nationwide group prevention program (called “Gruppenprophylaxe”) lasting from kindergarten up to sixth grade (12 years of age). Standardized recommendations are given concerning brushing systematics and brushing movements. N = 174 children at the age of 12 were thus randomly selected from two German towns and were asked to perform toothbrushing to the best of their abilities in front of a mirror which also served as a camera. Brushing behavior was analyzed by video analysis. Results Children brushed their teeth for an average of 200 s ± 80.48 s (mean ± SD). Still, more than 55% missed at least one sextant when brushing inner surfaces, 16% missed them all. Only 7.5% of the children brushed both inner and outer surfaces by the intended movements (vertical movements on the inner surfaces and circular movements on the outer surfaces) for at least 90% of the respective brushing time. Instead, horizontal brushing was very common on the lateral surfaces. Conclusions The present analysis indicates that children have low efficiency to adopt the tooth-brushing recommendations given in prevention programs. This is surprising as great endeavors are made to help children internalize the recommendations. Future research is needed to better understand which factors impede adoption of toothbrushing recommendations in children and which efforts are necessary to improve their toothbrushing abilities.

Abstract
Bad breath or halitosis affects a majority of the population from time to time, causing personal discomfort and social embarrassment. Here, we report on a miniaturized, microelectromechanical systems (MEMS)-based, amperometric hydrogen sulfide (H2S) sensor that potentially allows bad breath quantification through a small handheld device. The sensor is designed to detect H2S gas in the order of parts-per-billion (ppb) and has a measured sensitivity of 0.65 nA/ppb with a response time of 21 s. The sensor was found to be selective to NO and NH3 gases, which are normally present in the oral breath of adults. The ppb-level detection capability of the integrated sensor, combined with its relatively fast response and high sensitivity to H2S, makes the sensor potentially applicable for oral breath monitoring.

Abstract
BACKGROUND Little data are available regarding halitosis in Japanese children. The aim of the current study was to investigate the prevalence and risk factors associated with halitosis in Japanese elementary and junior high school children. METHODS The subjects consisted of 520 elementary (1st-6th grade: boys, n = 284; girls, n = 236) and 248 junior high (7th-9th grade: boys, n = 136; girls, n = 112) school children aged 6-15 years in Saitama Prefecture, Japan. A self-administered questionnaire survey; halitosis measurement using an organoleptic assessment method; and clinical oral examination were conducted. RESULTS Overall, 44.9% of subjects had halitosis. The proportion of boys with halitosis was 43.6% and that of girls was 46.6%. On logistic regression analysis, grade and tongue coating were significant predictors of halitosis. The 7th-9th graders were significantly more likely to have halitosis than 1st-3rd graders (OR, 1.83; P = 0.007). Subjects with area of tongue coating score 2 or 3 were 5.51-fold more likely to present with halitosis (P < 0.001) than those with area of tongue coating score 0 or 1. Similarly, subjects with thickness of tongue coating score 2 or 3 were 3.28-fold more likely to have halitosis than those with thickness of tongue coating score 0 or 1 (P < 0.001). CONCLUSIONS Halitosis in the school children is not a rare condition; instead, its occurrence is relatively high. Therefore, inclusion of a halitosis prevention and management component in school oral health programs would lead to the promotion of overall oral health.

Abstract
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.

Abstract
Background/purpose Periodontal diseases have been considered as a source of oral malodor or halitosis. Improvement of oral malodor in chronic periodontitis patients has recently been observed after nonsurgical periodontal therapy in combination with tongue cleaning and/or chlorhexidine mouth rinsing. The present study, however, evaluated the impact of nonsurgical periodontal therapy alone on the oral malodor in chronic periodontitis patients by comparing the intraoral concentrations of volatile sulfur compounds (VSCs) before and after nonsurgical therapy. Materials and methods Using a sulfide monitor, the total VSCs in exhaled breath were measured in 80 patients with chronic periodontitis prior to and 1 month after nonsurgical periodontal therapy (re-evaluation phase). Malodor was defined as a VSC score > 75 parts per billion (ppb) and > 110 ppb, respectively. Results Significantly lower level of VSCs was recorded at periodontal re-evaluation (55 ± 9.7 ppb) than before treatment (89 ± 16.3 ppb). Before treatment, 27 (34%) patients were considered to have malodor, defined as VSCs > 75 ppb. After treatment, 16 patients (20%) had VSC scores > 75 ppb, including 10 of 27 patients with baseline VSC scores > 75 ppb and six of 53 patients with baseline scores ≤ 75 ppb. The risk of malodor differed significantly before and after treatment (P = 0.035, McNemar's test). However, when malodor was defined as VSCs > 110 ppb, the difference in risk showed only borderline significance (P = 0.077). Conclusion On the basis of our findings, we suggest that nonsurgical periodontal therapy has a mild impact on oral malodor.

Abstract
Objective To investigate the factors associated with halitosis in Chinese white-collar employees. Materials and Methods Subjects in three randomly selected office buildings in Shanghai, China, were enrolled in this cross-sectional study using cluster random sampling. Oral malodor was assessed by measuring volatile sulfur compounds (VSCs) with a portable sulfide monitor. Subjects’ oral health, including dental caries, periodontal status, and tongue coating, was evaluated clinically. A questionnaire was used to obtain information about participants’ demographic characteristics, oral hygiene habits, and health behaviors. Results Of the 805 subjects invited to participate in this study, 720 were enrolled (89.4% response rate). Data from these subjects were used for statistical analyses. The prevalence of halitosis was 33.2%. In the final regression model, halitosis was significantly related to tongue coating thickness, periodontal pocket depth, no food consumption within 2 hours prior to oral examination, and less intake frequency of sweet foods. Conclusions In this Chinese white-collar population, tongue coating and periodontal disease were associated with halitosis. Oral hygiene education should be provided at the population level to encourage the maintenance of oral health and fresh breath. Consumption of sweet foods may reduce VSC production, although this finding requires further investigation.

Abstract
AIM No epidemiological data on halitosis are available from Italy. Thus, the aim of this population-based cross-sectional study was to estimate the prevalence of halitosis in an urban adult population from North Italy and to explore related oral risk indicators. MATERIALS AND METHODS The survey used a two-stage probability sampling method to collect a representative sample of inhabitants, aged between 20 and 75 years, in the city of Turin. Seven hundred and forty-four adults were clinically examined (47% of sampled subjects) for oral malodor and periodontal conditions. Using a standardized questionnaire social, health and halitosis-related parameters were collected. Logistic models with interaction terms between tongue coating scores (TCS) and periodontal status were used to explore halitosis risk indicators. RESULTS The prevalence estimate of halitosis according to the organoleptic assessment was 53.51% (95% CI: 48.55-58.50). A statistically significant correlation was found between organoleptic and gas chromatography measurements (p < 0.0001). Stronger associations between halitosis and periodontitis were observed in people having higher TCS: adjusted odds ratio considering low and high TCS in individuals with severe periodontitis were 2.95 and 20.77 (p ≤ 0.003). CONCLUSIONS Due to the high prevalence of halitosis in the Turin population, its diagnosis and management should be incorporated in comprehensive dental care.

Abstract
Aim: To assess the role of periodontal health in oral malodor causation and compare the two methods (organoleptic and Halimeter) of malodor measurement. Materials and Methods: A total of 240 subjects (60 subjects without any evidence of periodontal disease and 180 patients with gingivitis and periodontitis) were evaluated for periodontal and oral malodor parameters. Periodontal parameters included Plaque Index (PI), Gingival Index (GI), mSBI, calculus component of OHIS, pocket depth (PD), and clinical attachment level (CAL), and oral malodor was assessed by organoleptic scores, Halimeter readings, and Tongue Coating Index (TCI). Results: 80% of the sample when assessed organoleptically (i.e. 192 subjects) and 74.6% when assessed with Halimeter (i.e. 179 subjects) presented with varying degrees of halitosis. All the clinical parameters were significantly associated with oral malodor (P < 0.001). The amount of tongue coating and bleeding on probing played the most important role in increasing VSC concentration, followed by periodontal status, plaque indices, and calculus component. Conclusion: There was a high prevalence of halitosis in the present study population. All the clinical parameters were significantly related to oral malodor in this study, and the results indicate that determining VSC levels with Halimeter is a useful means of diagnosing halitosis objectively.

Abstract
Background There is some research on taste disorder/hyposensitivity in special groups such as the elderly or patients presenting with specific taste problems, however few studies have been conducted among young populations. The objectives of this study were to estimate the prevalence of taste hyposensitivity and to investigate the relationship between taste hyposensitivity and oral health status in Japanese schoolchildren. Methods Subjects were 237 primary and 112 junior high school students in Saitama Prefecture, Japan. In total, 349 (boys: 181, girls: 168) students aged 6–15 years participated in the study. Oral examinations and whole-mouth taste tests using four tastes (sweet, salt, sour and bitter) solutions were conducted on the subjects. A subject who could not recognize the taste of the solution was defined as demonstrating hyposensitivity. Results Hyposensitivity was observed in 6.3% of all subjects for sweet-taste, 14.3% for salt-taste, 20.9% for sour-taste and 6.0% for bitter-taste. The prevalence of sweet, sour and bitter-taste hyposensitivity decreased as the subjects’ grade advanced. In contrast, the prevalence of salt-taste hyposensitivity increased in 7th-9th grade subjects. Furthermore, the prevalence of bitter-taste hyposensitivity was significantly higher in males than females among 1st-3rd graders. Taste hyposensitivity had little association with oral health status, such as decayed teeth, filled teeth, dental plaque, gingival status and tongue coating. Conclusions In this study, taste hyposensitivity was observed in 6.0%-20.9% of the students. There was little association between taste hyposensitivity and oral health status. The current study implies that the factors affecting the taste hyposensitivity in children may different from those in the elderly. Therefore it is necessary to further investigate the causes of taste hyposensitivity among younger generation.

Abstract
OBJECTIVES To describe the characteristics of patients who visited halitosis clinic and to investigate the factors that may associate with halitosis. MATERIALS AND METHODS Nine hundred and eleven patients, who visited halitosis clinic for consultations, underwent organoleptic tests and volatile sulfur compound (VSC) measurements with a portable sulfide monitor. The oral health of patients, including dental caries, oral hygiene, and gingival inflammation status, was assessed. Questionnaires were used to obtain information on demographics, oral hygiene practices, and dietary habits. RESULTS Of the 911 patients, more females than males visited the clinic. Patients' age ranged from 18 to 82 years (mean ± s.d.: 40.8 ± 14.1). Almost 30% of patients had complained of halitosis for over 5 years before looking into treatments. Approximately half of the patients self-perceived that they were unable to get close to others. Around 77% of patients had halitosis. Results of multiple logistic regressions for organoleptic scores and VSC values showed that tongue coating and tongue scraping were significantly associated with halitosis (P < 0.05). CONCLUSIONS Among these Chinese patients, over three-quarters of patients had halitosis, and negative impacts on social communications were observed. Tongue coating was the most important factor responsible for halitosis.

Abstract
OBJECTIVE Previous research has suggested that oral malodor could be a useful motivational tool for increasing the awareness of oral health in adolescents and improving their oral health behaviors. Hence, the aims of this research were: (1) to develop an oral health education program that included oral malodor prevention and (2) to test the effects of the program in Japanese senior high school students by comparing the changes of oral health outcomes between the intervention and control groups. MATERIALS AND METHODS Subjects were 163 Grade 1 and 135 Grade 2 senior high school students in Tokyo, Japan. A novel oral health education program, which incorporated prevention of oral malodor, was developed and conducted on all Grade 1 students (intervention group). Grade 2 students (control group) did not receive the program. Changes in oral health status from baseline to 1-year follow-up were compared between the intervention and control groups. RESULTS The intervention group, compared with the control group, had a significantly higher proportion of students who improved or maintained good oral health status (i.e. dental plaque, gingivitis, tongue coating and oral malodor). Among students in the intervention group, the change was more evident in subjects with detectable oral malodor at the commencement of the program. CONCLUSIONS An oral health education program focusing on the prevention of oral malodor is effective for promoting oral health among Japanese senior high school students. Therefore, embedding such a program in the school oral health curriculum would be beneficial for adolescents.

Abstract
PURPOSE OF REVIEW The present article reviews the current knowledge of halitosis with particular emphasis upon the interplay of diet and disease of the gastrointestinal tract upon oral malodour. RECENT FINDINGS Transient-altered breath smell usually reflects the effects of foodstuffs, whereas longstanding halitosis is almost always because of oral disease such as gingivitis or periodontitis. There is, however, increasing evidence that upper gastrointestinal tract disease may give rise to halitosis and that extracts of foodstuffs may be future therapeutic agents for the treatment of halitosis derived from the mouth or upper gastrointestinal tract. SUMMARY There is some interplay between the halitosis and the gastrointestinal tract, and it is possible that the therapy of halitosis may be aided by investigations of the effects of foodstuffs upon bacteria that give rise to volatile sulphur compounds.

Abstract
AIM The main objective of this study was to investigate the prevalence of taste hyposensitivity and the relationships between sex, oral health status, and eating habits with taste hyposensitivity in Japanese senior high school students. METHODS Oral examinations, sweet and salt whole-mouth taste tests, and a questionnaire about eating habits were conducted on 234 senior high school students. Factors affecting taste hyposensitivity were investigated using a multivariate analysis. RESULTS Sweet-taste hyposensitivity was observed in 7.3% of the students, and salt-taste hyposensitivity in 22.2%. Approximately 3% of the students had both sweet- and salt-taste hyposensitivity, and 22.6% had either sweet- or salt-taste hyposensitivity. In total, 26% had a taste hyposensitivity. There were significant relationships between the intake of instant noodles with sweet-taste hyposensitivity, and the intake of vegetables or isotonic drinks with salt-taste hyposensitivity. CONCLUSIONS There was a significant association between eating habits and taste hyposensitivity in Japanese senior high school students. Taste tests would be a helpful adjunct for students to recognize variations in taste sensitivity, and a questionnaire about their eating habits might provide an effective self-review of their eating habits, and therefore, provide motivation to change.
