The Hall Technique and exfoliation of primary teeth: a retrospective cohort study.

Introduction There has been speculation about early exfoliation of carious primary molar teeth treated with the Hall Technique (HT).Aim To investigate the hypothesis that there is a difference in exfoliation times between teeth treated with the HT and contralateral teeth not treated with the HT.Methods Split-mouth retrospective cohort study of children treated in Dundee Dental Hospital and School (DDH&S). Radiographs and clinical records were assessed to compare children's ages at exfoliation for HT-treated primary molars and their contralateral teeth not treated with the HT. Primary molars' root resorption was also evaluated to assess whether the HT influenced the rate of root resorption.Results Using DDH&S's clinical systems, children's records (n = 13,160) were screened for children's ages and sequential radiographs, with 192 children potentially eligible. After assessing radiographs and clinical records, 39 children met the inclusion criteria. Their mean age at time of HT treatment was 7.2 years (range = 4.0 to 11.0; SD = 1.5). There was no evidence of a difference (p = 0.41) between children's ages at exfoliation of HT teeth (10.7; SD = 1.2 years) and contralateral teeth (11.0; SD = 1.4 years).Conclusion There is no evidence that use of the Hall Technique is associated with early exfoliation of primary molars.

Graphene-poly(nickel complex) as novel electrochromic nanocomposite for the fabrication of a robust solid-state device.

An electrochromic nanocomposite based on a nickel-salen polymeric film - poly[Ni(3-Mesalen)], Mesalen=N,N'-bis(3-methylsalicylideneiminate) - and graphene nanoplatelets (GFNPs) with enhanced electrochromic stability was successfully prepared by anodic electropolymerization. Although the electrochemical processes typical of the polymer film were not changed by the presence of graphene, higher electroactive surface coverages could be obtained for nanocomposite films, which suggest the incorporation of GFNPs into the polymeric network. The nanocomposite showed multi-electrochromic behavior, with color changes between yellow (reduced state) and green (oxidized state). The inclusion of GFNPs into the poly[Ni(3-Mesalen)] structure accelerates the switching process, with the response time for green coloration decreasing by 50.7% and for yellow coloration by 60.0%, for films prepared with 30 electropolymerization cycles. In terms of electrochemical stability, after 10,000 electrochemical cycles the loss of charge was 7% for the graphene nanocomposite. The nanocomposite film was used as electrochromic material to assemble a flexible solid-state electrochromic device (ECD), which exhibited an outstanding electrochemical stability - only 3% of charge loss after 15days of continuous activity.

Conflito intergeracional na família: relato de um projeto terapêutico singular / Intergenerational conflicts to a family: a case reporting of a singular therapeutic project

Introdução: o Projeto Terapêutico Singular (PTS) é uma abordagem integral à família, que propõe intervenções biopsicossociais, priorizando ações que atenuem os agravos potencializados pelos conflitos intergeracionais. Objetivos: descrever a aplicação de um PTS a uma família com conflitos intergeracionais e morbidades para o estabelecimento de ações depromoção em saúde. Métodos: o trabalho é descritivo, modalidade de relato de caso. O PTS constituiu-se de visita familiar, formulação de hipóteses para intervenção, definição de metas, discussão das metas entre equipe e família e a reavaliação das intervenções planejadas. Nas visitas foi aplicado roteiro semiestruturado contendo o histórico, papeis e relacionamento familiar, agravos, saúde, condições de moradia e higiene, convívio social.Os dados foram compilados nos instrumentos: genograma, ecomapa,escala de risco e diagnóstico multiaxial. Após a concordância da família quanto à divulgação dos dados, os genitores assinaram o Termo de Consentimento Livre e Esclarecido (TCLE). Foi preservado o sigilo dos indivíduos e dos dados coletados. Resultados: por meio da escuta empática e construção de vinculo, a equipe e a família planejaram ações de promoção da saúde e de tratamento de doenças, com enfoque nos agravos: pré-natal de adolescentegravida, planejamento familiar, segmento e adesão ao tratamento dedoenças como hipertensão, hanseníase e erisipela que acometiam indivíduosda família, problemas relacionados ao tabagismo e etilismo; evasão escolar, atualização de vacinas e conflitos intergeracionais. Conclusão: a compreensão do contexto familiar possibilitou o entendimento e a resolução conjuntos do processo saúde-doença e dos agravos potencializados pelo conflito intergeracional.

Introduction: Singular Therapeutic Project (STP) is an integral approachto a family which proposes biopsychosocial interventions andprioritizes actions that mitigate injuries enhanced by intergenerationalconflicts. Objective: describe the application of a STP to a family and its intergenerational conflicts and morbidities to establish health promotionactions. Methods: the article is descriptive in a case reporting format. A STP is consisted of family visits, hypotheses for intervention, goal setting and discussion of goals between family and team and review of planned actions.During visits a semi-structured script with historic, documents, family relationship, injuries, health, living conditions and social interactionhas been applied. Data were compiled in genogram and ecomap, risk scale and multiaxial diagnosis. The family read the document Informed Consent Form (ICF), signed it and agreed whit the publicationof data. Individuals and data’s confidentiality have been preserved.Results: through empathic listening, team and family planned togetherhealth promotion actions and diseases treatment, focusing on the injuries:a pregnant teenager’s prenatal; family planning; adherence to treatmentof diseases such as hypertension, leprosy and erysipelas, whichhave affected members of the family; and problems related to smokingand alcoholism, high school escape, update immunization and intergenerationconflicts. Conclusion: the comprehension of family context enabled understandingand resolution of health-disease process and injuries potentiated by intergenerational conflicts.
