Halitosis In Children Research Articles

Volatile sulfur compounds in asthmatic children and adolescents: A cross-sectional study in breath and saliva.

Halitosis in children implies psychosocial repercussions. Risk factors associated with this condition are unclear, and detection methods are inaccurate. 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. 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. 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. 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.

Prevalence of Halitosis in Children and Associated Factors: A Systematic Review and Meta-Analysis

Risk Factors, Diagnosis, and Management of Halitosis in Children: A Comprehensive Review

The present manuscript aims at providing a comprehensive overview of the epidemiology, risk factors, diagnostic aids, and management of halitosis in a pediatric population. Halitosis refers to bad breath from the mouth that seems unpleasant or offensive to others. This condition is prevalent worldwide, including all age-groups. However, studies on the pediatric population are limited. Self-confidence and personality development are important factors that the child builds up during their developmental stages. Halitosis may affect them both on personal and social aspects; hence, it is important to have beforehand knowledge and the modes to intercept it, paving the way to a positive growth of the child. On reviewing the literature, the common risk factors for halitosis in children constituted predominantly oral factors that varied from poor oral hygiene, gingivitis, periodontal diseases, dental caries, tongue coating, mouth breathing, and so on. Their diagnosis commonly included the organoleptic test, sulfide monitoring, and gas chromatography along with the assessment of questionnaire by the parents and older children. The management was predominantly directed toward the identified source of halitosis along with instructions and counseling on the benefits of a good oral hygiene regime. The importance of cultivating a day-to-day practice of oral hygiene regime in the children will not only accustom them toward the benefits of good oral health but also help them to tackle halitosis and in turn their inhibitions associated with it. Halitosis, though a prevalent condition experienced at various stages of life, is crucial to identify and manage, especially in the pediatric population owing to its influence on personal and on social aspects of life.

Halitosis and Associated Risk Factors in Children: A Cross-sectional Study

To investigate risk factors associated with halitosis in children using OralChroma™. Sixty-seven children between the ages of 3 and 8 who attended a pre-general anesthesia assessment at the Dental University Hospital at King Saud University, Riyadh, Saudi Arabia, were enrolled in this study after satisfying the inclusion criteria. Demographic data, medical history, and oral hygiene practices were obtained by a standardized questionnaire completed by the parents of each child. Clinical dental examination was conducted to record the following: caries index (dmft/DMFT), simplified debris index (DI-S), modified gingival index (MGI), and Winkel tongue coating index (WTCI). Clinical halitosis was assessed using the OralChroma™ device that measures the concentration of volatile sulfur compounds (VSCs) including hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3SCH3). Statistics were completed using Spearman's correlation coefficient and Mann-Whitney U-test to assess the association with the VSC scores with continuous and binary variables, respectively. Then, multivariate linear regression analysis was performed to detect the degree of association. High VSC measures were detected in 58 children (87%). The dmft/DMFT was significantly associated with H2S level (β = 26.84, p = 0.034) and CH3SH level (β = 19.96, p = 0.016) after controlling possible confounders. There was no significant association of DI-S, MGI, and WTCI with the VSC measures. The result suggested that dmft/DMFT score (children's caries experience) is associated significantly with high levels of H2S and CH3SH in the sample studied. Caries experience in children is a significant risk factor for halitosis and should be considered during the management of halitosis.

Dynamic Alterations of Oral Microbiota Related to Halitosis in Preschool Children.

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

Halitosis in Children Undergoing Full Mouth Rehabilitation under General Anesthesia.

Interventions and management modalities of pediatric halitosis have been suggested in the literature, however, the effect of full mouth rehabilitation (FMR) under general anesthesia (GA) on pediatric halitosis was not reported. Therefore, the present study was conducted to investigate parents’ perceptions of their child’s halitosis before and after FMR under GA; and to evaluate the effect of FMR on clinical halitosis. Fifty-seven children between 3–8 years old, scheduled for FMR under GA, were included after satisfying the inclusion criteria and upon parental consent. Parents’ perception of halitosis in their children was evaluated using a standardized questionnaire and a breath sample was collected to assess the level of volatile sulfur compounds (VSCs) using OralChromaTM before and after FMR under GA. Sixty percent (n = 34) of the parents perceived halitosis in their children before FMR and about 80% (n = 27) of them reported improvement in halitosis after FMR. Clinical halitosis was detected in 84.2% (n = 48) of the sample before treatment. A statistically significant reduction in halitosis was found in 56.3% (n = 27) of the children after treatment (p < 0.001). In conclusion, majority of parents perceived an absence or reduction of halitosis in their children following FMR and significant improvement of clinical halitosis.

Accuracy of a portable breath meter test for the detection of halitosis in children and adolescents

OBJECTIVES:This study aimed to determine the accuracy of the Breath-Alert™ portable breath meter (BA) for the detection of halitosis in children and adolescents, considering the organoleptic test (OT) as the gold standard in this assessment.METHODS:A cross-sectional study was conducted on 150 children (aged 6-12 years). OT was performed by three independent examiners on a single occasion, obtaining three scores of 0-5 points on the Rosenberg’s organoleptic scale. The median of the three evaluations for each child was used for analysis. BA was used according to the manufacturer’s instructions, with breath odor scored from 0-5 points. Scores ≥2 on both tests were considered indicative of halitosis.RESULTS:A total of 26 (17.3%) and 23 (15.3%) children were detected with halitosis on the OT and BA tests, respectively. The sensitivity and specificity of the BA scores for the detection of halitosis were 80.76% and 98.38%, respectively. The positive and negative predictive values for BA were 91.3% and 96.06%, respectively.CONCLUSION:In the present study involving children, who require fast, practical examinations, BA proved to be an auxiliary tool to OT for the detection of halitosis in the practice of pediatric dentistry, demonstrating high sensitivity and specificity.

Dental health, halitosis and mouth breathing in 10-to-15 year old children: A potential connection.

The relationship between mouth breathing and dental caries, gingival inflammation, and halitosis in children is contentious with studies reporting positive and negative associations; this study aimed at investigating the effect of mouth breathing on dental, gingival health status, and halitosis. An observational cross-sectional study was carried out involving 785 randomly selected children and adolescents between the ages of 10 and 15 in the city of Leipzig, Germany (LIFE Child cohort). Caries levels and gingival health status for the upper-right and the lower-left central incisors were assessed by evaluating ICDAS scores and CPI scores, respectively. A standardised questionnaire was used to assess self-reported mouth-breathing habit and halitosis. This study showed a statistically significant association between halitosis and mouth breathing (OR=3.0; 95% CI: 1.5-6.2), and a significant increase in mouth breathing habit in males compared to females (59.7% vs. 40.3%; p<0.05). There were no statistically significant differences in ICDAS scores, orthodontic treatment, CPI scores, or socioeconomic status between the mouth and nasal-breathing groups. Mouth breathing habit has no effect on the prevalence of caries or gingivitis based on examining the upper-right central incisor (11) and the lower-left central incisor. However, mouth breathers showed a significant increase in halitosis compared to nasal-breathing individuals.

The correlation between different techniques for the evaluation of oral malodour in children with and without orthodontic treatment.

The aim of this work was to evaluate the correlation between different methods (organoleptic evaluation, gas chromatography, salivary ?-galactosidases activity) for the evaluation of halitosis in children. The secondary purpose was to investigate the influence of orthodontic treatment on halitosis. Study Design: Oral malodour was detected with different methods in 50 children in the Paediatric Dentistry Unit, University of Rome Tor Vergata, Rome, Italy. During the dental visit, level of oral hygiene, tongue coating scores and presence of an orthodontic device, fixed or mobile, were recorded. Two trained and calibrated operators performed the organoleptic evaluation; the Oral ChromaTM device was used for the volatile sulfur compounds (VSCs) quantification and salivary ?-galactosidases (S?-g) activity was evaluated through the spectrophotometric method. The Cohen's Kappa score was used to evaluate the level of agreement between the operators. The Pearson's correlation coefficient was used to evaluate the linear relationship between continuous variables (e.g. S?-g vs. VSCs values) and the Spearman's correlation coefficient was calculated for ordinal variables (e.g. organoleptic scores) vs. other parameters. The LSD test was used to compare the parameters analysed in the study. A positive and significant correlation between the organoleptic evaluation, the S?-g, the levels of hydrogen sulfide (H2S) and methyl mercaptan (CH3SH) was found. The Spearman's correlation has shown that organoleptic scores were significantly correlated with S?-g (0.664, p<0.001) and the Oral ChromaTM measurements of H2S (0.538, p<0.001) and Ch3SH (0.316, p=0.026). The Pearson's correlation showed that S?-g was statistically significantly correlated with the Oral ChromaTM measurements of H2S (0.379 p=0.007) and Ch3SH (0.299, p=0.0035). Stratifying results for orthodontic treatment, it was possible to show that children under orthodontic treatment, both fixed or removable, were characterised by higher level of S?-g. The organoleptic evaluation and Oral ChromaTM measurements showed that children wearing fixed orthodontic were characterised by higher scores. There was a significant correlation between the three different techniques for the evaluation of oral malodour in children. Like in the adult population, the increase of S?-g activity was associated with oral malodour. The presence of fixed orthodontic appliances was correlated to increased scores of all methods for the evaluation of halitosis.

Halitosis in children with adenoid hypertrophy

This paper attempts to identify the sources and evaluate the prevalence of halitosis in children with adenoid hypertrophy. The study included pediatric patients admitted for adenoidectomy due to obstructive symptoms. Patients with possibly other causes of halitosis, were excluded from the study. Halitosis was detected in 30 out of 136 children (22.1%). The effect of adenoid hypertrophy on halitosis was confirmed by the significant reduction in the organoleptic score rated according to the Rosenberg scale (on average by 2°) and the levels of volatile sulfur compounds (on average 84 ppb) post-adenoidectomy, as compared to pre-surgery results. In total, we reported a statistically significant decrease in the abovementioned values in 90% of patients with halitosis. It was found that in patients with halitosis, as compared to patients with no oral malodor, anaerobic bacteria and Staphylococcus aureus were more frequently observed in the adenoid tissue. Streptococcus oralis strains were more commonly reported in the material taken during adenoidectomy in children without oral malodor.

Perception and awareness of halitosis in children by caregivers seen in our pediatric outpatient department

Introduction: Halitosis is defined as bad breath which is offensive to others, there are several causes of halitosis, however, diseases of the oral cavity are the most common causes such as periodontal disease, bacterial coating of tongue; in addition, sinusitis, suppurative diseases of the lungs, esophageal diseases, systemic disorders, and different types of food have been implicated. It is one of the common indications for dental consultation. However, there are limited studies that have explored caregivers' perception of halitosis in their children and their help-seeking attitudes toward halitosis in children. Materials and Methods: This study was cross sectional. It was conducted over 4 months from August 2017 to December 2017. Pretested questionnaires were administered by trained medical officers and house officers; a systematic random sampling method was employed. Results: There were 31 (20.7%) males and 119 (79.3%) females, with male-to-female ratio of 1:4. Most respondents did not perceived their ward's breath; similarly, they believed their wards did not have bad breath; however, among those with bad breath, majority were concerned, but most had not sought medical treatment. Surprisingly, majority of the respondents did not know the cause of bad breath; and educational qualification and ethnicity had no significant association with knowledge of the causes of halitosis. Majority of the ethnic groups were aware of halitosis, except the Fulanis; and this observation was statistically significant (χ2 = 15.170, df = 4, P = 0.004). Conclusion: There was poor knowledge of the causes of halitosis among the respondents; and few respondents sort for medical treatment for halitosis.

Halitosis in children

Halitosis is manifested by fetid breath, unpleasant for the affected person and for those with whom he interacts, with unfavourable impact on quality of life and self esteem. Epidemiological data about the prevalence in the general population differs, being between 8% and 45.7%. Halitosis is three times more common in men and is reported in particular after the age of 20 years. References to the child in the medical literature are sporadic.

An objective assessment of halitosis in children with adenoid vegetation during pre- and post-operative period

ObjectivesAlthough most specialists in otorhinolaryngology and pediatrics find halitosis to be a common problem in children with adenoid hypertrophy, there are no objective data on this topic in the literature. Whether adenoid hypertrophy is a risk factor for halitosis or whether halitosis is a sign of adenoid hypertrophy remains unclear. Thus, the aim of this study was to investigate whether children diagnosed with adenoid hypertrophy have a higher probability of halitosis than do children in the normal population and whether adenoidectomy can decrease oral malodor. MethodsForty children with adenoid hypertrophy and 40 healthy subjects aged 5–15 years were included in the study. The children with adenoid hypertrophy underwent adenoidectomy operations and were followed for 3 months. We measured volatile sulfur compounds (VSCs), hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3)2S using an objective method, a portable gas chromatograph (OralChroma; AbiMedical, Osaka, Japan). ResultsThe mean CH3SH and (CH3)2S levels were significantly different (p < 0.05) between the adenoid hypertrophy group and the controls. The H2S, CH3SH, and (CH3)2S levels in the third postoperative month were significantly lower (p < 0.05) than those in the preoperative period, and there was no significant difference postoperatively between the patients with adenoid hypertrophy and controls. There was a positive correlation between age and VSC levels, and CH3SH levels were significantly higher in patients with ventilation tube insertion, rather than just adenoidectomy. ConclusionsThere was a statistically significant association between halitosis and adenoid hypertrophy, and a significant improvement in halitosis was obtained following adenoidectomy. The present study provides an association between halitosis and adenoid hypertrophy. If there is no other oral pathology causing halitosis, halitosis can be a sign of adenoid hypertrophy in children.

Impact of Chlorhexidine Pretreatment Followed by Probiotic Streptococcus salivarius Strain K12 on Halitosis in Children: A Randomised Controlled Clinical Trial.

The aim of this study was to examine the effect of chlorhexidine disinfection, as a chemical method of oral hygiene practice, and subsequent use of probiotics on halitosis in children. The effects of mechanical and chemical oral hygiene practice methods on the severity of halitosis were also assessed. 208 children with organoleptic test (OLT) scores of 2 or more were randomly assigned to four groups: A: conventional oral hygiene practices (COH) including toothbrushing and flossing; B: COH + tongue scraping (TS); C: COH + TS + chlorhexidine; D: COH + TS + chlorhexidine + probiotics. OLT was performed at 1-week and 3-month follow-ups. A significant and stable number of participants showed major and moderate levels of improvement in OLT scores in group D (p < 0.001). The improvement of OLT scores in group C was also significant (p < 0.001), but not stable over the follow-ups (p = 0.44). Neither significant nor stable improvements in the OLT scores were detected in groups A and B through follow-ups (p > 0.05). Probiotic therapy following oral disinfection with chlorhexidine may reduce the severity of halitosis over longer periods.

Use and perceived benefits of mouthwash among Malaysian adults: An exploratory insight

Halitosis has become a major concern, as it is the third most common reason for dental visits and affects individuals across all ages, genders, and ethnicities. Only a few limited studies have explored the prevalence and etiology of halitosis in the pediatric population. Therefore, the aim of this review was to identify the etiological factors influencing the widespread occurrence of halitosis in pediatric dentistry in order to guide therapy based on the identified causes, thereby improving children's quality of life. The etiology of halitosis is multifactorial; however, in most cases, halitosis is associated with the oral cavity. It can also be related to otorhinolaryngological and respiratory or even gastric diseases. Although halitosis in children is widely associated with poor oral hygiene, we cannot rule out other possible causes, such as otorhinolaryngological and respiratory causes.

Association between the organoleptic scores, oral condition and salivary β-galactosidases in children affected by halitosis.

The goal of this work is to evaluate the association between organoleptic scores, oral condition and salivary β-galactosidases, to facilitate the differential diagnosis of halitosis in children. Fifty systemically healthy children with a primary complaint of oral malodour were included in this cross-sectional study. The organoleptic evaluation was carried out by two judges, evaluating the intensity of malodour of the air exhaled 5 s through the mouth of the patients, at a distance of approximately 10 cm from their noses; the level of salivary β-galactosidases was quantified spectrophotometrically after a chromatic reaction between a salivary sample of each patient and a specific chromatic substrate of the enzyme. Clinical conditions, such as visible plaque and gingival bleeding index, tongue coating score, localized food stagnation and other oral parameters, were evaluated by qualified dentists through an oral check-up. The β-galactosidase level was significantly related to the organoleptic scores and clinical parameters, such as the tongue coating score and the visible plaque index. Stratifying results with respect to the different phase of the day at which parents complained halitosis in their children, statistical analysis showed that the organoleptic scores and the level of β-galactosidases were significantly higher in children who suffered of halitosis during the whole day, A = 40%, with respect to those without this problem, N = 20% (P = 0.001 and P = 0.006, respectively). Certain oral parameters such as halitosis during the whole day, high tongue coating score and high visible plaque index were particularly associated with an increase in the salivary β-galactosidase level.

Prevalence of halitosis in children considering oral hygiene, gender and age

To date, few studies have addressed halitosis in the paediatric population. As such, the aim of the present study was to investigate symptoms, signs and risk factors associated with halitosis in healthy children and to present a model based on the clinical data that predicts the presence of halitosis. A total of 101 individuals were included. All patients received a questionnaire that queried on sociodemographic characteristics, self-reported halitosis and dental treatment history. Individuals received a thorough intra-oral examination, and the volatile sulphur compounds (VSC) were measured to test the presence of halitosis with a portable sulphide monitor (Halimeter(®); Interscan Co., Chatsworth, CA, USA). The distribution of the sociodemographic characteristics, self-reported halitosis, dental treatment history and other oral features was evaluated. Finally, a statistical model was constructed with the best set of features to predict halitosis in children. The median age was 12.0 years (mean: 11.7 ± SD 2.7) with 54.5% males. Halitosis (VSC > 100 parts per billion, or ppb) was objectively measured in 37.6% of patients. For comparison purposes, Bayesian network was obtained using clinical and demographic data. The model consisted of four variables (sex, age, oral hygiene status and self-reported halitosis) directly related to the presence of halitosis (VSC > 100 ppb). This model achieved 76.4% area under receiver operating characteristics curve (AUROC). Overall, female patients or individuals with dental plaque on more than 25% of the dental surfaces or patients older than 13 year old were more prone to present with halitosis. The results suggest that halitosis in the paediatric population is related to poor oral hygiene and may be more common in females and older individuals. This specific predictive model may be useful to identify subgroups to target for intervention to treat oral halitosis.

The relationship between tongue brushing and halitosis in children: a randomized controlled trial

The study aimed to investigate the clinical and microbiological effects of tongue brushing on malodour in children. One hundred and fifty-one caries-free children were included. After clinical evaluation, halitosis was determined by organoleptic assessment and sulphide monitoring. Then, 69 children with high levels of volatile sulphur compounds (VSC) were randomly assigned into two groups (group 1: scaling-polishing + tooth brushing + tongue brushing and group 2: scaling-polishing + tooth brushing), and tongue coating samples were collected for microbiological analysis. After 2 weeks, VSC measurements, organoleptic assessment, clinical evaluations and sample collection were repeated. In both groups, organoleptic scores, VSC levels, gingival index, plaque index (PI), bleeding on probing and Winkel tongue coating index (WTCI) scores decreased after 15 days. However, only the change in WTCI and PI scores showed a statistically significant intergroup difference. The most prevalent anaerobic bacteria were Veillonella spp., Prevotella spp., Fusobacterium spp., and no intergroup difference was observed in terms of colony counts of bacteria. Tongue brushing did not provide an additional benefit to the treatment for malodour. According to the microbiological culture results, a specific bacterium responsible for halitosis in children could not be identified and more sensitive methods might be used for this purpose.
