%X OBJECTIVE: To evaluate the association of breastfeeding duration, pacifier use and nasal air flow with occlusal disorders among children. METHODS: This cross-sectional observational study included 138 children aged 4 and 5 years selected in all the daycare centers of the city of Campo Limpo Paulista, Brazil. Questionnaires were applied to mothers to identify total duration of exclusive breastfeeding and non-nutritive sucking. The independent variables were: Sucking (pacifier, bottle, finger), breastfeeding duration and nasal air flow. The dependent variables were: Open bite, crossbite, overjet, overbite, diastema and maxillary deficiency. Frequency distribution calculations were performed, a chi-square test, the Fisher exact test and, after that, stepwise logistic regression were used for statistical analysis, and the level of significance was set at 5%. RESULTS: The use of a pacifier was the most deleterious factor and increased chances of having open bite in 33.3 times, marked overjet in 2.77 times and posterior crossbite in 5.26 times. CONCLUSION: There was a significant association between non-nutritive sucking, particularly the use of a pacifier, and occlusal disorders. These findings are important to plan the treatment of preschoolers. OBJETIVO: avaliar a associa  o do tempo de amamenta  o natural, tempo de uso de chupeta e aera  o nasal em rela  o a problemas oclusais em crian as. M¨¦TODOS: foi realizado um estudo observacional transversal com universo de 138 crian as entre 4 e 5 anos, de creches de Campo Limpo Paulista/SP. Foram aplicados question¨¢rios ¨¤s m es com o intuito de identificar o tempo de amamenta  o natural total e exclusiva e h¨¢bitos delet¨¦rios. Utilizaram-se as vari¨¢veis independentes h¨¢bitos delet¨¦rios (chupeta, mamadeira e dedo), tempo de amamenta  o natural e aera  o nasal; e as vari¨¢veis dependentes mordida aberta, mordida cruzada, overjet, sobremordida, presen a de diastema e atresia. Foram realizados c¨¢lculos das distribui  es das frequ¨ºncias, teste de associa  o do qui-quadrado, exato de Fisher e, em seguida, regress o log¨ªstica pelo m¨¦todo de stepwise, utilizando n¨ªvel de significancia de 5%. RESULTADOS: o uso de chupeta foi considerado o mais prejudicial dos h¨¢bitos delet¨¦rios, aumentando em 33,3 vezes a chance de mordida aberta; 2,77 vezes a chance de apresentar overjet acentuado e 5,26 vezes as chances de apresentar mordida cruzada posterior. CONCLUS O: houve uma forte associa  o entre h¨¢bitos delet¨¦rios (especialmente o tempo de uso de chupeta) e problemas oclusais, sendo esse fato importante no planejamento do tratament
