OBJECTIVE: To determine whether there is a correlation between halitosis and mouth breathing in children. STUDY DESIGN: Fifty-five children between 3 and 14 years of age were divided into two groups (nasal and mouth breathing) for the assessment of halitosis. A descriptive analysis was conducted on the degree of halitosis in each group. The chi-square test was used for comparison between groups, with a 5% level of significance. RESULTS: There was a significantly greater number of boys with the mouth-breathing pattern than girls. A total of 23.6% of the participants had no mouth odor, 12.7% had mild odor, 12.7% had moderate odor and 50.9% had strong odor. There was a statistically significant association between halitosis and mouth breathing. CONCLUSIONS: The occurrence of halitosis was high among the children evaluated, and there was a statistically significant association between halitosis and mouth breathing.
PURPOSE: to determine the occurrence of anterior open bite and harmful oral habits in children from four to six-year old. METHODS: a total of 266 four-to-six-year-old male and female children in the city of Suzano (São Paulo, Brazil) were evaluated. An assessment chart for detecting the occurrence of harmful oral habits was administered to the guardians and clinical exams were performed for assessing occlusion in the children. RESULTS: a total of 221 children (83.1%) had at least one harmful oral habit, the most frequent of which was the use of a feeding bottle (n=167; 75.6%). The occurrence of simultaneous harmful habits and dental occlusion abnormalities was observed in 119 children (44.1% of the sample); among these children, the greatest prevalence was of anterior open bite (n=89; 79.8%). CONCLUSION: anterior open bite was the most prevalent occlusion alteration in the children and had a statistically significant association with harmful oral habits, such as the use of a bottle and/or pacifier and teeth grinding.
OBJETIVO: verificar a ocorrência de mordida aberta anterior e de hábitos orais deletérios em crianças de quatro a seis anos de idade. MÉTODOS: foram avaliadas 266 crianças de quatro a seis anos incompletos, de ambos os gêneros, na cidade de Suzano - São Paulo. As avaliações constaram de aplicação de ficha de avaliação para detecção de ocorrência de hábitos bucais deletérios aos responsáveis e da realização de exame clínico constituído por avaliação da oclusão das crianças. RESULTADOS: verificou-se que 221 crianças (83,1%) apresentaram pelo menos um hábito bucal deletério, sendo o mais frequente o uso de mamadeira 167 (75,6%). A ocorrência simultânea de hábitos deletérios e alterações de oclusão dentária foi observada em 119 crianças (44,1% da amostra) e nestas, a maior prevalência foi a presença da mordida aberta anterior, presente em 89 (79,8%). CONCLUSÃO: a mordida aberta anterior (MAA) foi a alteração oclusal mais prevalente nas crianças, havendo associação estatisticamente significante entre hábitos orais deletérios, como uso de mamadeira, chupeta e ocorrência de bruxismo e presença de mordida aberta anterior.
