ABSTRACT In this article, based on Appreciative Inquiry, we present and discuss the best practices of a group of preceptors from a multiprofessional health residency program in Brazil. The best practices we identified are the multiprofessional consultation, the reception given to residents, and the integrated actions among different majors of the residency. In addition, we identified their strategies to develop the practices in health settings. The practices follow the presuppositions of interprofessional education, as they promote the reflection of different actors on the construction of practices that aim at the provision of better healthcare for users of the Brazilian National Health System (SUS).(AU)

Assessment of the effects of decontamination and storage methods on the structural integrity of human enamel / Avaliação dos efeitos de métodos de descontaminação e armazenamento sobre a integridade estrutural do esmalte humano

Introduction: The storage of teeth for use in research is a controversial issue with no consensus on the most appropriate treatment method for this purpose. Objective: The aim of this study was analyze the effectiveness and the influence of different methods of decontamination and storage of human enamel samples, in order to maintain their integrity. Material and method: The sample consisted of 124 molars distributed randomly into three groups according to the method: control - distilled water, 0.1% thymol and 0.02% sodium azide. The tests performed were laser fluorescence, surface microhardness and profilometry analysis (0, 15 and 30 days) and Microbiological test (7, 15 and 30 days). Data were analyzed by the ANOVA and Tukey tests (P <0.05). Result: In the laser fluorescence test, thymol proved to be more feasible for maintaining the integrity of the dental organ, since it did not show significant variations in values among the analyzed periods (P> 0.05). The surface microhardness analysis showed loss of tooth structure in all methods, and sodium azide led to a lower level of tooth loss. Profilometry analysis showed loss of mass in all groups whereas sodium azide showed the greatest loss. None of the methods was able to inhibit bacterial growth. Conclusion: Among the processing methods analyzed none was able to combine effective decontamination and storage with maintenance of the structural integrity of the human enamel.

Introdução: O armazenamento de dentes para utilização em pesquisas é uma questão controvérsia e não há consenso sobre o método de tratamento mais apropriado para esta finalidade. Objetivo: O objetivo deste estudo foi analisar a efetividade e a influência de diferentes métodos de descontaminação e armazenamento do esmalte dentário humano, a fim de manter sua integridade. Material e método: A amostra foi constituída por 124 molares distribuídos aleatoriamente em três grupos, de acordo com o método: controle – água destilada, soluções de timol a 0,1% e de azida de sódio a 0,02%. Os testes realizados foram fluorescência a laser, microdureza de superfície e análise de perfilometria (0, 15 e 30 dias) e teste microbiológico (7, 15 e 30 dias). Os dados foram analisados por meio dos testes ANOVA e Tukey (p<0,05). Resultado: No teste de fluorescência a laser, a solução de timol a 0,1% demonstrou ser mais viável na manutenção da integridade do órgão dentário, uma vez que este não apresentou variações significativas nos valores entre os períodos avaliados (p<0,05). A análise de microdureza de superfície evidenciou perda de estrutura dentária em todos os métodos, sendo que a azida de sódio promoveu menor perda dentária. Na análise de perfilometria observou-se perda de estrutura em todos os grupos, com maior perda no grupo azida de sódio. Nenhum dos métodos conseguiu inibir o crescimento bacteriano. Conclusão: Dentre os métodos de processamento analisados nenhum foi capaz de aliar a efetividade na descontaminação ao armazenamento com manutenção da integridade estrutural do esmalte dentário humano.

Randomized controlled clinical trial of long-term chemo-mechanical caries removal using PapacarieTM gel

Objectives: Compare the effectiveness of PapacarieTM gel for the chemo-mechanical removal of carious lesions on primary teeth to conventional caries removal with a low-speed bur with regard to execution time, clinical aspects and radiographic findings. Material and Methods: A randomized controlled clinical trial with a split-mouth design was carried out. The sample was composed of 20 children aged four to seven years, in whom 40 deciduous teeth were randomly divided into two groups: chemo-mechanical caries removal with PapacarieTM and removal of carious dentin with a low-speed bur. Each child underwent both procedures and served as his/her own control. Restorations were performed with glass ionomer cement. The time required to perform the procedure was also analyzed. The patients underwent longitudinal clinical and radiographic follow-up of the restorations. Results: No statistically significant difference between groups was found regarding the time required to perform the procedures and the radiographic follow up. Statistically significant differences between groups were found in the clinical evaluation at 6 and 18 months after treatment. Conclusion: PapacarieTM is as effective as the traditional method for the removal of carious dentin on deciduous teeth, but offers the advantages of the preservation of sound dental tissue as well as the avoidance of sharp rotary instruments and local anesthesia. .

Efficacy of Papacarie¯ in reduction of residual bacteria in deciduous teeth: a randomized, controlled clinical trial

OBJECTIVES: The aim of the present study was to analyze the efficacy of Papacarie¯ gel compared with the traditional method (low-speed bur) in reducing the counts of total bacteria, Lactobacillus, total Streptococcus and Streptococcus mutans group. METHODS: A randomized, controlled clinical trial with a split-mouth design was performed. The sample comprised 40 deciduous teeth in 20 children (10 males and 10 females) aged four to seven years. The teeth were randomly allocated to two groups: G1, or chemomechanical caries removal with Papacarie Duo¯, and G2, or the removal of carious dentin tissue with a low-speed bur. Infected dentin was collected prior to the procedure, and the remaining dentin was collected immediately following the removal of the carious tissue. Initial and final counts of bacterial colonies were performed to determine whether there was a reduction in the number of colony-forming units (CFUs) of each microorganism studied. ClinicalTrials.gov: NCT01811420. RESULTS: Reductions were found in the numbers of total bacteria, total Streptococcus and Streptococcus mutans group following either of the caries removal methods (p<0.05). A reduction was also noted in the number of Lactobacillus CFUs; however, this difference did not achieve statistical significance (p>0.05). CONCLUSION: Papacarie¯ is an excellent option for the minimally invasive removal of carious tissue, achieving significant reductions in total bacteria, total Streptococcus and S. mutans with the same effectiveness as the traditional caries removal method. .

Análise microbiológica do efeito da terapia fotodinâmica antimicrobiana na descontaminação de superfície de titânio / Microbiological analysis of the effect of antimicrobial photodynamic therapy in the decontamination of titanium surface

Diversos métodos de descontaminação de superfícies de implantes têm sido propostos para o tratamento da peri-implantite, como uso de clorexidina, ácidos e lasers. Até o momento, nenhum método foi totalmente estabelecido como ideal para o tratamento da doença. Diante disso, este estudo objetivou avaliar a capacidade de descontaminação da terapia fotodinâmica antimicrobiana em superfície de titânio. Discos de titânio de superfície rugosa foram divididos em 3 grupos de 5 discos cada um: a PDT, constituído por discos contaminados por placa dentobacteriana e descontaminados pela terapia fotodinâmica antimicrobiana; E, discos estéreis (controle negativo) e C, discos contaminados por placa dentobacteriana e não tratados (controle positivo). A avaliação do potencial descontaminante da terapia fotodinâmica antimicrobiana foi feita através da quantificação do crescimento bacteriano pela contagem das unidades formadoras de colônia após semeadura em ágar sangue. Aos resultados, foram aplicados ANOVA a um critério e pós-teste de Tukey com nível de significância de 5%. O grupo a PDT demonstrou potencial descontaminante significativo em relação ao grupo C, embora tenha permanecido inferior ao grupo E. A terapia fotodinâmica antimicrobiana apresentou apenas potencial bacteriostático nas primeiras 8 horas, quando não foi possível visualizar crescimento bacteriano. Concluiu-se que, ainda não existem evidências suficientes para que a terapia fotodinâmica antimicrobiana possa ser definida como um adjuvante no tratamento para os casos de peri-implantite

Several methods for decontamination of implant surfaces have been proposed to the treatment of peri- -implantitis, including the use of chlorhexidine, acids, and lasers. Until this moment, no method is fully established as a gold standard to the treatment of the peri-implantitis. Therefore, this study aimed to evaluate the potential of antimicrobial photodynamic therapy for decontamination on titanium surface. Rough surface titanium discs were divided into 3 groups of 5 discs each: a PDT, which consisted of discs contaminated by dental plaque and decontaminated by antimicrobial photodynamic therapy; E, sterile discs (negative control) and C, discs contaminated by dental plaque and untreated (positive control). The evaluation of the potential of antimicrobial photodynamic therapy for decontamination was made through the quantification of bacterial growth by counting the colony forming units after sowing in agar-blood. On the results was applied one way ANOVA and Tukey post-test with 5% of significance. The PDT group showed significant potential for decontamination in relation to the C group, although the a PDT remained insufficient in relation to the E group. The antimicrobial photodynamic therapy presented bacteriostatic potential only at the first 8 hours, when it was impossible to see bacterial growth. It was concluded that there is no sufficient evidence to establish antimicrobial photodynamic therapy as an adjuvant to the treatment of peri-implantitis cases

Genetic lineages in the yellow fever mosquito Aedes (Stegomyia) aegypti (Diptera: Culicidae) from Peru

The yellow fever mosquito Aedes aegypti was introduced in Peru in 1852 and was considered to be eradicated in 1958. In 2001, Ae. aegypti had been recorded in 15 out of 24 Peruvian Departments. Peru has great ecological differences between the east and west sides of Andes. Because of this, we consider that Ae. aegypti populations of both east and west sides can have a genetically distinct population structure. In this study we examined genetic variability and genealogical relationships among three Ae. aegypti Peruvian populations: Lima, Piura (west Andes), and Iquitos (east Andes) using a fragment of the ND4 gene of the mitochondrial genome. Three haplotypes were detected among 55 samples. Lima and Iquitos showed the same haplotype (Haplotype I), whereas Piura has two haplotypes (Haplotype II and III). Haplotype II is four mutational steps apart from Haplotype I, while Haplotype III is 13 mutational steps apart from Haplotype I in the network. The analysis of molecular variation showed that mostly of the detected genetic variation occurs at interpopulational level. The significant value phist suggests that Piura population is structured in relation to Lima and Iquitos populations and the gene flow of the ND4 is restricted in Piura when compared to Lima and Iquitos. Genetic relationship between haplotype I and haplotype II suggests introduction of the same mtDNA lineage into those localities. However the existence of a genetically distant haplotype III also suggests introduction of at least two Ae. aegypti lineages in Peru.
