Percepção materna sobre atenção odontológica e fonoaudiológica na gravidez / Maternal perception of dental, speech and hearing care during pregnancy

Objetivo: Conhecer a percepção das gestantes atendidas no Pré-Natal Obstétrico do Hospital Universitário de Santa Maria (RS) sobre a atenção odontológica e fonoaudiológica durante a gravidez. Método: Foram entrevistadas 75 gestantes por meio de questionário contendo perguntas relacionadas à saúde materna e do bebê. A análise foi de natureza descritiva. Resultados: Apenas 58,7% das gestantes frequentaram o consultório odontológico durante a gestação, embora todas as entrevistadas consideram importante cuidar da saúde bucal durante este período. A maioria das grávidas apresentou dúvidas sobre até que período o bebê deveria ser amamentado e qual o momento adequado para o desmame. A maioria (96,0%) informou que é necessário realizar a higiene bucal do recém-nascido, porém houve inúmeras dúvidas com relação ao modo de como fazê-la. Um número significativo de gestantes (77,0%) considerou prejudicial beijar o filho na boca assim como provar o leite e a comida. Sessenta e dois por cento tiveram controle da ingestão de açúcar durante o período gestacional e 92,0% das gestantes nunca ouviram falar do teste da orelhinha. Conclusão: Pôde-se observar que as gestantes detêm algum conhecimento sobre as questões abordadas, no entanto, alguns pontos precisam de maiores esclarecimentos, sobretudo em saúde, com enfoque odontológico e fonoaudiológico, propiciando uma atenção holística para o binômio mãe-bebê.

Objective: The objective of this study is to investigate how pregnant women seen at the Prenatal Obstetric Clinic of the University Hospital in Santa Maria perceive dental, speech and hearing care. Method: A questionnaire was administered to 75 pregnant women with questions related to mother and baby health. The analysis was of a descriptive nature. Results: Only 58.7% of the pregnant women saw a dentist on a regular basis during pregnancy, although all interviewees believed that oral care during this period was important. The majority of the pregnant women were uncertain about how long to breastfeed and when to wean. Most of them (96%) stated that oral hygiene of the newborn was necessary, but there were many doubts on how to do it. A significant number (77%) of pregnant women thought kissing the baby´s mouth or tasting his or her milk or other foods was harmful. More than half (62%) of the women controlled their sugar intake during pregnancy and 92% of them had never heard of the ear test. Conclusion: The results showed that pregnant women have some knowledge of the issues discussed; however, some points need clarification, especially health issues. There should be a focus on teeth, speech and hearing so as to provide a holistic care for the mother-child dyad.

Comparative scanning electron microscopic study of the effect of different dental conditioners on dentin micromorphology

This study evaluated comparatively by scanning electron microscopy (SEM) the effect of different dental conditioners on dentin micromorphology, when used according to the same protocol. Forty dentin sticks were obtained from 20 caries-free third human molars and were assigned to 4 groups corresponding to 3 conditioners (phosphoric acid 37 percent, Clearfil SE Bond and iBond) and an untreated control group. After application of the conditioners, the specimens were immersed in 50 percent ethanol solution during 10 s, chemically fixed and dehydrated to prepare them to SEM analysis. In the control group, dentin surface was completely covered by smear layer and all dentinal tubules were occluded. In the phosphoric acid-etched group, dentin surface was completely clean and presented exposed dentinal tubule openings; this was the only group in which the tubules exhibited the funnel-shaped aspect. In the groups conditioned with Clearfil SE Bond primer and iBond, which are less acidic than phosphoric acid, tubule openings were occluded or partially occluded, though smear layer removal was observed. SE Bond was more efficient in removing the smear layer than iBond. In the Clearfil SE Bond group, the cuff-like aspect of peritubular dentin was more evident. It may be concluded all tested conditioners were able to change dentin morphology. However, it cannot be stated that the agent aggressiveness was the only cause of the micromorphological alterations because a single morphological pattern was not established for each group, but rather an association of different aspects, according to the aggressiveness of the tested conditioner.
