Estudo do efeito de cério como sensibilizador e ativador, em matrizes de difenilfosfinatos de lantânio, dopadas com európio e/ou térbio

This paper aims the preparation, characterization and study of luminescence, particularly as for the cerium ion action as activator or sensitizer, in diphenylphosphinate of lanthanum compounds trivalent ions cerium-, europium-, and/or terbium-doped. The following compounds were prepared and studied: i) La1-(x+y)CexEuy(DFF)3; ii) La1-(x+y)CexTby(DFF)3; iii) La1-(x+y+z)CexEuyTbz(DFF)3, with x = 10%, y = 5% e z = 5%. The diphenylphosphinate of lanthanum, Ln[(Ph2)PO2]3, are complexes obtained by the mixture of lanthanides chlorides with diphenylphosphinic acid, ethanol medium. These compounds make white powders, crystalline, insoluble in normal temperature and pressure, and are chemically and thermally stable. When doping with Ce3+, Eu3+ and/or Tb3+, the compounds present characteristic luminescence. Luminescent materials are made of a host matrix incorporated with few amounts of ions called activators, which are able to present luminescence after being excited by UV light or high energy radiation, and sensitizer ions, which have the role of absorbing excitation energy and transfer it to the activator, for it to emit luminescence radiation. The infrared vibrational spectroscopy indicates that the coordination occurs by the oxygens of phosphorile group with ΔνPO of about 40 cm-1 compared to the free ligand. The X Ray difractograms of compounds Eu- and/or Tb-doped are similar, but they present profile of diffraction different observed by Stucchi and col. In previous papers, indicated an influence of Ce in the crystalline phase formation of these matrices. In luminescence spectrums, the excitation that can be made by the levels of ligand in 273 nm, or cerium ion in area between 300 and 400 nm were observed. In the emission spectrum, with excitation in 273 nm, is possible to observe the emission of Ce3+ below 400 nm and the Eu3+ in 592, 611 and 617 nm, and the...as a sensitizer to.

Estudo comparativo entre cinco diferentes tratamentos sobre as alterações clínicas e laboratoriais do rato diabético induzido pela aloxana

OBJETIVOS: Este estudo visa a analisar os efeitos, a longo prazo, de cinco diferentes tratamentos sobre o controle metabólico de ratos diabéticos aloxânicos. MÉTODOS: Foram analisados 7 grupos experimentais, com 50 ratos cada um, sendo: GN o grupo controle normal; GD o grupo controle diabético, sem tratamento; GI, GA e GIA os grupos tratados, respectivamente, com insulina, acarbose e associação insulina + acarbose; GTIL o grupo tratado com transplante de ilhotas de Langerhans; e o GTPD o grupo tratado com transplante pancreatoduodenal heterotópico. Parâmetros clínicos (peso, ingestão hídrica, ingestão alimentar e diurese) e laboratoriais (glicemia, glicose urinária e insulina plasmática) foram avaliados em todos os animais, no início do experimento, e após 1, 3, 6, 9 e 12 meses de seguimento. RESULTADOS: À exceção do GN, mortalidade foi observada em todos os grupos experimentais no seguimento de 12 meses (GD= 50%; GI= 20%; GA= 26%; GIA= 18%; GTIL= 4%; GTPD= 20%). em GD, GI, GA e GIA os óbitos ocorreram por distúrbios metabólicos ou hidroeletrolíticos e/ou pneumonia, diarréia e caquexia; em GTIL e GTPD todos os óbitos ocorreram por falhas técnicas no pós-operatório até 72h. Animais dos grupos GI, GA e GIA tiveram melhora significativa (p < 0,05) de todos os parâmetros clínicos e laboratoriais observados em ratos diabéticos, sem diferença de efetividade entre os tratamentos. Porém, os resultados observados nestes grupos, biologicamente não foram comparáveis aos observados em GTIL e GTPD, onde observou-se correção completa, aos níveis normais, de todas as variáveis analisadas (p<0,01). CONCLUSÕES: Os tratamentos convencionais com insulina, acarbose e insulina + acarbose melhoraram o estado diabético grave dos ratos tratados, contudo, a eficácia dos tratamentos foi significativamente inferior à oferecida pelo GTIL e GTPD.

Abordagens periodontais na promoção da harmonia do sorriso

Several therapeutic approaches have been proposed in order to achieve an esthetically pleasing and harmony smile. The present study reports a case in which gingivectomy was performed in the region of the upper anterior teeth combined with osteotomy in the region of the upper posterior teeth and removal of the superior labial frenum to promote harmony smile by decreasing the gummy smile and adequacy of buccal corridor. Osteoplasty gingivoplasty, and frenectomy procedures were planned and performed in a single session. The extraction of the maxillary third molars was also performed in order to avoid postoperative complications. Follow-up visits were performed at 7, 15, 30 and 180 days postoperatively. At 7 days, the gingival tissue was in the initial process of healing, demonstrating inflammation still in evidence. At 15 days, the gingival tissue was found in the final healing process, showing characteristics of normal health gum. At 30 days, there was complete healing of gingival tissues without clinical exposure of the root surfaces. After 180 days, tissues remained in healthy, demonstrating the success of the treatment. Patient showed complete satisfaction with the results. It can be concluded that, when properly indicated, the combination of gingivectomy, osteotomy and frenectomy procedures are promising therapeutic approaches for promoting harmony smile.

Diabetes mellitus: avaliação do conhecimento de cirurgiões-dentistas em municípios de três estados brasileiros

Introduction: Pathological changes in the bucal cavity associated with Diabetes mellitus (DM) may include gingivitis, periodontal disease, salivary gland dysfunction and xerostomia (dry mouth), susceptibility to bucal infections, burning mouth syndrome, and altered taste. Objective: This study assessed the technical and scientific knowledge of dentists working in primary care in the National Health System (SUS) on the DM. Material and method: The study was conducted in the municipalities of Birigui-SP, Maringá-PR and TrêsLagoas-MS, with the participation of 76 dentists working in the SUS primary care system.These professionals agreed to answer to a questionnaire developed for this study and the results of the questions were submitted to a quantitative analysis. Result: Showed that 94.7% were in contact with diabetic patients; 97.4% know what is DM; about other types of DM, 77.6% said they know, the most mentioned (by 55.9%) was the gestational DM. The DM2 was indicated as the most prevalent by 59.2%; the normal range of fasting blood glucose level was quoted correctly by 2.6% of the participants; obesity was reported by 98.7% of participants as a risk factor for DM; 96.0% stated correctly what are the main signs and symptoms related to Diabetes; periodontal disease was reported by 92.1% as an bucal manifestation in diabetic patients. Conclusion: The dentist needs to develop specific knowledge about DM, being able to identify normal levels of blood glucose and ready to identify and meet the bearer of DM.

Parafunctional activities in brazilian children and adolescent

The etiology of TMD in children and adolescents is considered multifactorial and has been related to parafunctional habits.The objective of this research was to determine the prevalence of parafunctional habits in elementary school students of “Colégio Ipê de Assis” (Assis, SP - Brazil). In the present research was administered questionnaire (15 questions) proposed by the Center for Diagnosis and Treatment of TMD, School of Dentistry of Araçatuba, UNESP. The sample was composed of 80 elementary school students of the “Colégio Ipê de Assis” (Assis, SP - Brazil). The project was approved by the Ethics Committee in Research of the School of Dentistry of Araçatuba/ UNESP. All parents and responsible of the students received instruction about the research and preservation of identity and provide clarification if in doubt. Beyond that, they were requested to sign the informed consent in order to facilitate the participation of students. Females comprised 47,5% and males 52,5%, with age ranging from 10 to 14. The students were classified into two groups as follows: Group I-female, Group II- male. In addition, brazilian students from Groups I and II were classified according to type of oral habits presented. All students presented a parafunctional habit. Among the parafunctional habits chewing gum was the most common in both groups (72.2%, Group I and 78.5%, Group II) followed by resting chin on hand for both genders (69,5% for Group I and 67% for Group II). Tongue biting (5%) was less founded in Group II and stomach sleeping in Group I. The results obtained show the necessity of carring out preventive programs. Beside, resources of Health should increase preventive treatments.

Tratamento tardio de traumatismo dentário anterior pela técnica de apicificação

Introdução: paciente do sexo masculino, 37 anos de idade. Após a anamnese, foi constatado que o dente 11 apresentava abertura coronária e presença de hidróxido de cálcio com histórico de trauma dentário nesse dente. Radiograficamente, o dente 11 apresentava formação radicular incompleta, paredes dentinárias finas e frágeis, com divergência foraminal associada a imagem radiolúcida periapical. Objetivo: relatar um caso clínico de apicificação, realizado com trocas de curativo de hidróxido de cálcio. Métodos: o tratamento de escolha foi a apicificação, a qual teve início na segunda sessão, após 15 dias, por meio de desbridamento químico-mecânico de todo o canal radicular, com limas tipo K e irrigação com uma solução de hipoclorito de sódio a 2,5%. Em seguida, pasta de hidróxido de cálcio (hidróxido de cálcio, iodofórmio e propilenoglicol) foi aplicada e trocada de 15 em 15 dias, durante 4 meses. O exame radiográfico foi novamente realizado e demonstrou o fechamento completo da abertura foraminal e regressão da radiolucência periapical. O canal radicular foi obturado utilizando-se um cone confeccionado a partir da união de três cones #60 e pela técnica de condensação lateral com Sealapex. Resultados: seis meses após a obturação, exames revelaram tecidos periapicais normais e ausência de sintomas. Conclusão: concluiu-se que o tratamento do traumatismo dentário associado à necrose do tecido pulpar e à lesão periapical, com trocas sucessivas de pasta de hidróxido de cálcio, foi adequado para se obter a regressão da lesão periapical, formação de barreira mineralizada e promoção de saúde ao paciente.
