And, it is also possible to conclude the monitoring and execution control are paramount to the success of the diaphragm wall construction

Produção de biofilme por bastonetes gram negativos isolados de água de hemodiálise

No Brasil, 90% de pacientes com insuficiência renal crônica ou aguda dependem dos procedimentos de hemodiálise para remover produtos de degradação metabólica, excesso de água e de sais minerais do organismo, a fim de restaurar o equilíbrio ácido-base e eletrolítico. Entretanto, o processo de osmose reversa, que visa remover todos os íons da água, também remove o cloro, que exerce efeito bacteriostático sob diversas bactérias autóctones, que passam a se multiplicar na água. Entre os principais grupos dessas bactérias, estão os bastonetes Gram negativos não fermentadores (BGN) e os mais frequentemente associados a bacteremias, em pacientes de hemodiálise são Pseudomonas aeruginosa, Stenotrophomonas maltophilia e Burkholderia cepacia. Essas bactérias podem produzir biofilmes, o que torna sua eliminação do encanamento quase impossível. Assim, o objetivo do trabalho foi a análise de água e do dialisato, da Unidade de Hemodiálise de um Hospital Universitário, na pesquisa dos três BGNs citados. Também foram utilizadas 42 cepas previamente isoladas do mesmo local. Entre as 67 amostras de água, foram isoladas 8 cepas de Pseudomonas aeruginosa e as 50 cepas foram submetidas à pesquisa do gene rpoS, um dos responsáveis pela produção de biofilme. Esse gene foi observado em 20 (40%) cepas, sendo 16 (80%) P. aeruginosa, seguida por 3 (15%) cepas de S. maltophilia e 1 (5%) de B. cepacia. Essas cepas foram submetidas à produção de biofilme a 35ºC (temperatura ótima de crescimento) e a 20ºC (temperatura média da água no encanamento da Unidade de Hemodiálise), em aço inoxidável (material de muitos instrumentos cirúrgicos), PVC (matéria prima da tubulação) e plástico de poliestireno (capacidade de produção de biofilmes em diferentes materiais). Em poliestireno, somente 1 (5%) cepa de P. aeruginosa produziu biofilme a 35ºC e a 20ºC, 2 (10%) cepas foram... (Resumo completo, clicar acesso eletrônico abaixo)

Fechamento de diastema anterior: associação de procedimentos ortodôntico e restaurador

Several aspects beyond the restorative phase itself such as orthodontic movement and periodontal treatment must be considered in cases of closure of diastemas. In such cases, a multidisciplinary approach is essential. As patients during orthodontic treatment may show high risk of developing dental caries and periodontal disease, inflammation of the gingival tissue is a common finding. For this reason, a preliminary basic periodontal treatment is critical to the success of restorative procedure. In addition, postoperative care and instruction in phonetics, oral hygiene and periodic control must be considered by professionals and patients. Thus, this paper demonstrates through a case report, pre and postoperative issues that should be considered during the closure of diastemas using a layering technique with resin composites

Estudo cefalométrico comparativo dos traçados predictivos e resultados ortodôntico-cirúrgicos em pacientes com face longa

The purpose of this research was to compare, by cephalometric analysis (McNamara and Legan & Burstone) the predictive tracings (by methods manual, and by softwares Dentofacial Planner Plus and Dolphin Image) with the post surgical results. Were selected the pre and post surgical lateral telerradiograph (six months after orthognatic surgery) of the 25 long face patients treated with combined orthognatic surgery. Were made the prediction tracings for each method and comparing cephalometrically with the post surgical results. This protocol was repeated once more for the error method evaluation, and the statistical was made by variance analysis and Tuckey overtest. The results show more frequency of the cephalometric values' aproximation of the post surgical results when the manual method (50% of the similarity with the post surgical result), followed of the DFPlus (31,2%) and Dolphin (18,8%) softwares. The experimental condition permits to conclude that the manual method had more precision, although the previsibility of the digital methods was reasonable satisfactory.

Clareamento interno em dentes despolpados como alternativa a procedimentos invasivos: relato de caso

The increasing interest of patients for a better aesthetic appearance of their smile, associated with the development of new materials and techniques, encouraged by media couverage of this concept of beauty, provided an important evolution of cosmetic dentistry. As the darkness of a single anterior tooth or a group of teeth, in most cases, impairs the appearance of the smile and there is growing appreciation of the less invasive procedures, the technique of tooth bleaching is an important option for aesthetic treatment. To have success in the bleaching treatment, it is important to have knowledge of the origin, nature and composition of the stain. Among the causes of color changes acquired post-eruptive, dental trauma, with or without pulp necrosis, is one of the most commonly encountered etiologies, characterized by a reddish-brown color. Current techniques of bleaching for teeth treated endodontically employ oxidative agent hydrogen peroxide. The objective of this paper is to describe the immediate technique of bleaching non-vital tooth by presenting a clinical case.

Repercussões endodônticas dos procedimentos clareadores

Tooth bleaching is a treatment modality that raises great interest, due to the important role played by aesthetics in current life style. To perform such procedure, nowadays, there are several bleaching substances at several concentrations, as well as, diverse clinical techniques. When suggesting this procedure, the dentist should take into consideration several factors related to the patient to determine which will be the most appropriate technique/material combination for solving the clinical problem. The procedure indication should not only be based on the expectations exhibited by the patient, but also on respecting the biological principles to maintain the integrity of both the endodontic and periodontal tissues.

Conhecimento de mães sobre os procedimentos de emergência nos casos de avulsão dentária

Introduction: Despite tooth avulsion following trauma being relatively common in children, the available studies show that adults have limited knowledge about it. Aim: The purpose of this study was to assess, by a questionnaire, the mothers’ general knowledge about the immediate management of tooth avulsion. Material and method: This descriptive study was carried out on a convenient sample of mothers (n= 65) who participated of the “Pastoral da Criança”, from Araraquara, SP, Brazil. The questionnaire comprised 15 questions about personal data and knowledge on tooth avulsion management. Results: Participants were, on average, 35 years old. A total of 30.8% of the mothers reported that their children suffered dental trauma. The majority had never received advice on this subject (76.9%); and did not know how teeth are kept in the dental arch (69.2%). Almost a half of the sample believed that an avulsed tooth can be replanted (49.2%). In relation to the management of tooth avulsion, 40% of them would clean the avulsed tooth with water, even if it was not dirty (38.5%). Most of them (69.2%) would take the tooth by hand for cleaning purposes, regardless the tooth region; and believed that brushing the tooth was important to take the dirty out (67.7%). Conclusion: The general knowledge of mothers about the immediate management of tooth avulsion was considered inadequate endangering the successful treatment of tooth avulsion.
