LOPES, Montalverne H. B et al. Prevalence of self-reported halitosis and associated factors in adolescents from southern Brazil. Acta odontol. latinoam. [online]. 2016, vol.29, n.2, pp.93-103. ISSN 1852-4834.

The aim of this study was to assess the prevalence of selfreported halitosis and associated factors in adolescents from Passo Fundo, Brazil. Additionally, we studied adolescents’ concern with their own breath and whether anyone had ever told them that they had halitosis. A crosssectional observational survey was conducted on 15to 19 year old high school students from public and private schools in the city of Passo Fundo, Brazil. The random sample consisted of 736 adolescents from 20 schools. An interview with a structured questionnaire was administered. The prevalence of selfreported halitosis and associated factors was analyzed by either the chisquare test or Fisher’s exact test. The prevalence of selfreported halitosis was 39.67%. The mother’s level of education was associated with the outcome. Gender and behavioral habits were not associated with selfreported halitosis. Halitosis reported by others presented a prevalence of 10.73% and was associated to male gender and oral hygiene habits. Individuals with less toothbrushing frequency and no use of dental floss were associated to halitosis reported by others. It was observed that 88.58% of the participants are concerned with halitosis. It is concluded that there is high prevalence of selfreported halitosis, which is associated with a socioeconomic pattern. Most adolescents report concern with their own breath.
