Knowledge and perception of parents regarding halitosis in their children in Saudi Arabia.

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

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

AIM: To investigate risk factors associated with halitosis in children using OralChroma™. MATERIALS AND METHODS: 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. RESULTS: High VSC measures were detected in 58 children (87%). The dmft/DMFT was significantly associated with H2S level (ß = 26.84, p = 0.034) and CH3SH level (ß = 19.96, p = 0.016) after controlling possible confounders. There was no significant association of DI-S, MGI, and WTCI with the VSC measures. CONCLUSION: 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. CLINICAL SIGNIFICANCE: Caries experience in children is a significant risk factor for halitosis and should be considered during the management of halitosis.

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.
