Consequences of bottle-feeding to the oral facial development of initially breastfed children

OBJECTIVE To identify and assess the possible consequences of bottle-feeding on the oral facial development of children who were breastfed up to at least six months of age. METHOD Two hundred and two children (4 years of age) enrolled in an early health attention program participated in the study. The sample was divided into two groups: G1 (children who used only a cup to drink) and G2 (those who used a bottle). RESULTS Lip closure was observed in 82% of the children in G1 and in 65% of those in G2 (p = 0.0065). The tongue coming to rest in the maxillary arch was found in 73% of the children in G1 and in 47% of those in G2 (p = 0.0001). Nasal breathing was observed in 69% of G1 and in 37% of G2 (p = 0.0001). The maxilla was shown to be normal in 90% of G1 and in 78% of G2 (p = 0.0206). CONCLUSION Use of the bottle, even among breastfed children interferes negatively with oral facial development.

Conseqüências do uso da mamadeira para o desenvolvimento orofacial em crianças inicialmente amamentadas ao peito

OBJETIVO: Identificar e avaliar as possiveis consequencias do uso da mamadeira sobre o desenvolvimento orofacial em criancas que foram amamentadas ate pelo menos, os 6 meses de vida. METODOS: Participaram do estudo 202 criancas (4 anos de idade) que frequentaram o Programa de Atencao Precoce a Saude. A amostra foi dividida em: G1 (criancas que utilizaram apenas copo para ingestao de liquidos) e G2 (utilizaram mamadeira). RESULTADOS: Selamento labial foi observado em 82% das criancas do G1 e em 65% do G2 (p = 0,0065). Repouso da lingua no arco superior foi encontrado em 73% das criancas do G1 e em 47% do G2 (p < 0,0001). Observou-se maior ocorrencia de respiracao nasal em 69% do G1 e em 37% do G2 (p < 0,0001). A maxila mostrou-se normal em 90% do G1 e em 78% do G2 (p = 0,0206). CONCLUSAO: Usar mamadeira, mesmo entre criancas que receberam aleitamento materno, interfere negativamente sobre o desenvolvimento orofacial.

Hipoplasia de esmalte em dentes decíduos

Enamel hypoplasia may be the result or environmental, systemic or genetic events that interfere in the development of a normal enamel matrix. The present study describes cases of deficient enamel development in patients of the Research and Dental Treatment Center for Special Patients (FOP - Unicamp). With this purpose a first survey was carried out to select patients with complete teething in the period of August to December, 2003. Considering this period of time it was identified 31 children that presented some kind of enamel deficiency and showed 175 affected teeth. Greater frequencies of enamel deficiency were observed in second molar teeth, followed by first molars, canines, lateral and central incisives. Vestibular and occlusal tooth faces were those more frequently observed in the studied sample. Key words: pediatric dentistry, enamel defects, hypoplasia.
