The aim of this study was to explore oral malodour in 30 healthy, 7-15-year-old children who attended a dental faculty with this complaint. Organoleptic measurements, which is a subjective method for measuring malodour, and volatile sulphur compounds (VSCs) together with other parameters such as caries prevalence and tongue surface coating were recorded. These were taken before and after instruction in oral home care, which included tongue-brushing and the restoration of carious teeth but not use of mouthwashes. Tongue coating, periodontal disease measurements, plaque index and age were associated with oral malodour but there were no relationships with caries activity, gender or frequency of toothbrushing. Treatment resulted in resolution of oral malodour although '3 subjects (10%) remained in the malodor group'.
