ABSTRACT
Abstract Objective: To characterize the lingual frenulum of full-term newborns using two different protocols and to assess the association of the lingual frenulum with breastfeeding. Methods: This non-probabilistic sample consisted of 449 mother/baby binomials. For the anatomo-functional evaluation of the frenulum, the Neonatal Tongue Screening Test and the Bristol Tongue Assessment Tool were used for the evaluation of the lingual frenulum. Breastfeeding was evaluated using the protocol proposed by UNICEF. Scores were created (good, fair, poor) to evaluate every aspect of the breastfeeding to be observed. The results were analyzed through descriptive and inferential statistics and association tests (Pearson's chi-squared and Fisher's exact test). Results: The study showed that 14 babies had a lingual frenulum alteration, of whom three had difficulties during suction, requiring frenotomy in the first week of life, whereas 11 had no difficulties during breastfeeding. Regarding the breastfeeding evaluation, 410 mother/baby binomials had good, 36 regular, and three had bad scores. There was a statistically significant association between the tongue-tie test protocol and breastfeeding (p = 0.028) and between the Bristol Tongue Assessment Tool protocol and breastfeeding (p = 0.028). Conclusion: Alterations in the lingual frenulum are associated with interferences in the quality of breastfeeding and thus, evaluation of the lingual frenulum in newborns is important.
Resumo Objetivo: Caracterizar o frênulo lingual de recém-nascidos a termo, utilizando dois protocolos diferentes e verificar a relação do frênulo lingual com o aleitamento materno. Método: A amostra não probabilística foi constituída por 449 binômios mãe/bebê. Para a avaliação anatomofuncional do frênulo, utilizou-se o protocolo de avaliação do frênulo lingual para bebês "Teste da Linguinha" e o Bristol Tongue Assessment Tool. A mamada foi avaliada com o protocolo proposto pelo UNICEF. Foram criados escores (bom, regular, ruim) para avaliar cada aspecto da mamada a ser observada. Os resultados foram analisados através de estatísticas descritivas e inferenciais e testes de associação (Qui-quadrado de Pearson e Exato de Fisher). Resultados: O estudo mostrou que 14 bebês apresentaram alteração de frênulo lingual, nos quais três com dificuldade durante a sucção, necessitando de frenotomia na primeira semana de vida e 11 sem dificuldades durante a amamentação. Quanto à avaliação da mamada, 410 binômios mãe/bebê apresentaram o escore bom, 36 regular e 3 ruim. Houve associação estatisticamente significativa entre o protocolo "Teste da Linguinha" e amamentação (p = 0,028) e entre o protocolo Bristol Tongue Assessment Tool e amamentação (p = 0,028). Conclusão: Alterações no frênulo lingual estão associadas a interferências na qualidade da amamentação, sendo importante a avaliação do frênulo lingual em recém-nascidos.

Objective: To evaluate the use of nanosilver fluoride in the enamel remineralization process through optical coherence tomography. Material and Methods: All samples were submitted to demineralization process by pH cycling during 14 days and randomly distributed into three groups (n = 11): Nanosilver Fluoride (NSF), Sodium fluoride (NaF), and negative control. Optical coherence tomography images were acquired at three different moments: initial stage (T0), post caries formation (T1), and post pH cycling (T2). The integrity of the enamel surface and the measurement of the volume loss for the tissue after pH cycling in comparison to initial images were obtained from optical coherence tomography images. Results: After analyzing the exponential decay of A-scans from each group, it was possible to identify differences in light propagation among samples. In T1 it is not possible to visualize the dentin-enamel junction, probably due to the higher back scattering of the demineralized enamel, which does not allow light to reach the dentin. The decay curves obtained from NaF and nanosilver fluoride groups showed similar behavior, while the negative group showed lower extinction coefficient. Conclusion: Nanosilver fluoride showed the best effect against caries compared to conventional fluoride treatments.

Objetivo: Avaliar se os critérios radiográficos clássicos de indicação de terapia pulpar em dentes decíduos vêm sendo observados no cotidiano das atividades clínicas. Método: Foram avaliados 359 prontuários de pacientes atendidos na clínica de odontopediatria da Faculdade de Odontologia de Pernambuco (FOP/UPE), no período de janeiro de 2011 a junho de 2013. Dentre os 359 prontuários avaliados, 64 registraram tratamento pulpar em 78 dentes decíduos, os quais compõem a amostra final deste estudo. Mediante as radiografias intraorais, contidas nos prontuários, foram observados o grau de destruição coronária, o estágio de desenvolvimento de Nolla da raiz do sucessor permanente e o grau de rizólise do dente decíduo. Resultados: observou-se que a idade média das crianças incluídas no estudo foi de 6,62 anos (± 1,98). Em 11,5% dos casos, o critério que previa condições para que o dente decíduo pudesse ser restaurado não foi seguido, e em 32% dos casos não foram levados em consideração o grau de rizólise do dente decíduo ou o estágio de Nolla. Conclusão: Os critérios radiográficos clássicos de indicação para terapia pulpar em dentes decíduos não estão sendo rigorosamente observados na clínica odontopediátrica da instituição de ensino avaliada, indicando o risco de iatrogenias serem reproduzidas pelos futuros profissionais.
Aim: To assess whether the radiographic classic criteria of pulp therapy indication in deciduous teeth have been observed in daily clinical activities. Methods: A total of 359 records of patients attended in pediatric dentistry clinic of the Faculty of Dentistry of Pernambuco (FOP / UPE), from January 2011 to June 2013. Of the 359 records evaluated 64 registered pulp treatments in 78 primary teeth, which make up the final sample. Through intra-oral radiographs, contained in the medical records, the degree of coronary destruction, the Nolla stage of development of the permanent successor root and the degree of tooth root resorption deciduous were observed. Results: It was observed that the average age of the children included in the study was 6.62 years (± 1.98). In 11.5% of cases, the criterion which provided conditions for the deciduous tooth could be restored was not followed, and in 32% of cases were not taken into account the degree of tooth root resorption deciduous or Nolla stage. Conclusion: The classic radiographic criteria indication for pulp therapy in primary teeth, are not being strictly observed in Pediatric Dentistry of assessed educational institution, indicating the risk of iatrogenic be reproduced by future professionals.
