Atuação do residente cirurgião-dentista em equipe multiprofissional de atenção hospitalar à saúde materno-Infantil / Activities of a dental resident in a multiprofessional team focused on mother and child health care

A atuação do cirurgião-dentista no ambiente hospitalar é uma perspectiva recente no contexto brasileiro, sendo pouco investigada e sistematicamente relatada. Este estudo descritivo retrospectivo objetivou descrever as atividades desenvolvidas por cirurgiões-dentistas residentes, inseridos em uma equipe multiprofissional de um hospital universitário de referência. Buscou-se os registros e fichas clínicas dos pacientes atendidos pelos residentes em Odontologia da área de Atenção à Saúde Materno-Infantil do Hospital das Clínicas, da Universidade Federal de Goiás, na cidade de Goiânia-GO, entre fevereiro de 2011 e julho de 2012, para caracterizar os pacientes e descrever os procedimentos odontológicos executados. Os dados foram analisados por meio de estatística descritiva. Foram atendidos 740 pacientes no período analisado e 1290 consultas odontológicas foram realizadas. Uma diversidade de alterações sistêmicas foi verificada em 29% da amostra atendida (n=207 pacientes). As atividades educativo-preventivas (n=706) foram mais frequentes do que as atividades curativas (n=66). No período analisado, as atividades multiprofissionais foram realizadas foram estudos de casos (n=18), grupos de educação em saúde (n=49) e reuniões de planejamento multiprofissional (n=17). Concluiu-se que: o cirurgião-dentista pode atuar de forma abrangente no contexto hospitalar; considerando a área materno-infantil, as atividades educativo-preventivas ocorreram em maior número do que as curativas; o cirurgião-dentista deve ser estimulado, desde a graduação, a compreender os aspectos diferencias do contexto hospitalar no planejamento do tratamento odontológico e no trabalho multiprofissional.

The responsibility of the dentist in the hospital environment is a recent perspective in the Brazilian context, and this subject is rarely systematically investigated and reported. This retrospective descriptive study aimed to describe the activities performed by dental residents, entered into a multidisciplinary team of a university hospital. We selected records of patients seen by dental residents in the area Maternal and Child Health, in the Clinical Hospital, Federal University of Goiás, Goiânia-GO, between February 2011 and July 2012, to characterize them and describe dental procedures performed. Data were analyzed using descriptive statistics. A total of 740 patients were seen in that specific period and 1,290 dental consultations were held. A variety of systemic disorders were observed in 29% of the sample (n = 207 patients). Educative-preventive activities (n = 706) were more frequent than curative activities (n = 66). Over that period, the multidisciplinary activities were case studies (n = 18), heal the education for particular groups (n = 49), and planning meetings (n = 17). We concluded that: dentists have a broad spectrum of activities in hospitals; regarding the maternal and child health, educational and preventive activities were more frequent than therapeutic ones; dentists should be encouraged since undergraduation to understand the aspects of the hospital context that influence in treatment planning and multidisciplinary work.

Ação antimicrobiana de medicações intracanal sobre dentina infectada de dentes decíduos e permanentes

Objetivo: o objetivo deste estudo foi avaliar a efetividade antimicrobiana de medicações intracanal em dentina infectada de dentes decíduos e permanentes. Métodos:blocos de dentina foram inoculados com Enterococcus faecalis a cada 72 horas durante 60 dias; após, foram irrigados,secos e completamente preenchidos com uma das misturas a seguir: 1) pó de hidróxido de cálcio, própolis e propilenoglicol, 2) pó de hidróxido de cálcio e propilenoglicol,3) pó de hidróxido de cálcio e água destilada,4) própolis e propilenoglicol, 5) própolis e água destilada.Após 30 dias, as amostras foram lavadas com água destilada esterilizada, imersas em Letheen broth e incubadas por 48 horas a 37ºC. Resultados e Conclusão: a hipótese de que a associação do hidróxido de cálcio com própolis poderia ser mais eficaz do que os outros medicamentos não foi confirmada, pois os resultados indicaram que todas as misturas testadas não foram capazes de inibir o biofilme de E. faecalis, tanto nos blocos de dentina de dentes decíduos como permanentes

Mesiodistal root angulation of permanent teeth in children with mixed dentition and normal occlusion

OBJECTIVE: There is little information regarding the mesiodistal angulation of permanent teeth in mixed dentition. The aim of this study was to evaluate mesiodistal root angulation of permanent incisors, canines and first molars of 100 Brazilian children, using a new horizontal reference plane based on the midpoint of the intercuspation of primary canines and permanent first molars in panoramic radiographs during the mixed-dentition phase. MATERIAL AND METHODS: Children were equally divided between the genders with a mean age of 8.9 years (SD=0.76), normal occlusion and no eruptive disturbances. RESULTS: The angulation of the permanent maxillary first molars was close to the vertical, whereas the mandibular molars presented approximately 25 degrees of distal root angulation. The maxillary canines were the most distally angulated teeth, whereas the permanent mandibular canines were vertically positioned. The evaluation of the anterior maxillary area showed vertical position of permanent lateral, and central incisors with a slight distal angulation, whereas the permanent mandibular incisors tended to a mesial radicular convergence. CONCLUSIONS: The proposed reference line could be useful in mixed dentition root angulation evaluation; there was a slight asymmetry in the mesiodistal angulation among homologous teeth, and also a small variation between the male and the female groups, but no difference between 8-and 10-year-old children.

Structure and microstructure of coronary dentin in non-erupted human deciduous incisor teeth

The dentin structure of non-erupted human deciduous mandibular and maxillary central and lateral incisor teeth was studied employing light and scanning electron microscopy. For light microscopy, nitric-acid-demineralized and ground sections were used. The sections were stained by hematoxylin-eosin, picrosirius and azo-carmim methods, and ground specimens were prepared using a carborundum disk mounted in a handpiece. For SEM study, teeth were frozen in liquid nitrogen and fractured at longitudinal and transversal directions. Structurally, demineralization and ground methods revealed tubules with primary and secondary curvatures, canaliculi, giant tubules, interglobular dentin, predentin, and intertubular dentin. Scanning electron microscopy showed three-dimensional aspects of dentinal tubules, canaliculi, peritubular dentin, intertubular dentin, and predentin. This study contributes to knowledge about dentin morphology showing characteristics of teeth not yet submitted to mastication stress

A sem study of prismless enamel in non-erupted human deciduos teeth

The frequency, structure, and thickness of the prismless enamel layer in the bucal and lingual surfaces of nonerupted anterior deciduous teeth were described. The samples were fixed in a modified Karnovsky solution, longitudinally fractured in liquid nitrogen and observed by scanning electron microscopy. The aprismatic area was observed in the incisal and perpendicular to the enamel outer surface. Some depressions were observed on the enamel surface. The statistical analysis showed no significant differences related to prismless enamel thickness among upper and lower central incisors, lateral incisors and canines, which varied from 4,19 to 5.15um.
