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.

Volatile Sulfur

Schizophyllum commune is a causative agent of allergic bronchopulmonary mycosis, allergic fungal rhinosinusitis, and basidiomycosis. Diagnosis of these diseases remains difficult because no commercially available tool exists to identify the pathogen. Unique volatile organic compounds produced by a pathogen might be useful for non-invasive diagnosis. Here, we explored microbial volatile organic compounds produced by S. commune. Volatile sulfur compounds, dimethyl disulfide (48 of 49 strains) and methyl ethyl disulfide (49 of 49 strains), diethyl disulfide (34 of 49 strains), dimethyl trisulfide (40 of 49 strains), and dimethyl tetrasulfide (32 of 49 strains) were detected from headspace air in S. commune cultured vials. Every S. commune strain produced at least one volatile sulfur compound analyzed in this study. Those volatile sulfur compounds were not detected from the cultures of Aspergillus spp. (A. fumigatus, A. flavus, A. niger, and A. terreus), which are other major causative agents of allergic bronchopulmonary mycosis. The last, we examined H2S detection using lead acetate paper. Headspace air from S. commune rapidly turned the lead acetate paper black. These results suggest that those volatile sulfur compounds are potent targets for the diagnosis of S. commune and infectious diseases.
