Polishing for glass ceramics: Which protocol?

Purpose: The execution of adjustments on ceramic restorations is sometimes necessary for either correction of occlusion and/or inadequate contours or esthetical improvements. Clinically, the surfaces undergo weariness through fine grinding diamond burs which remove the superficial glazing layer. Several materials for ceramic polishing have been used in an attempt to reach a satisfactory surface smoothness. The aim of this study was to perform a literature review on different polishing protocols of several dental ceramics. Study selection: This is a literature review performed through scientific articles published between 2004 and 2012, indexed in MEDLINE, PubMed and Scielo databases. The study selected and analyzed a total of 20 relevant articles that evaluated different types of ceramics, polishing treatment and surface roughness.Results: After an extensive literature review, this study observed: 1 - after the rupture of the glazing layer due to the adjustments of the restorations, the best choice for the polishing of the surface will depend on the type of ceramics used; 2 - glazing procedure provide excellent results regarding to the superficial smoothness; however, if reglazing is impossible, either abrasive rubber cups/points or sandpaper discs followed by the use of diamond polishing pastes results in a satisfactory superficial smoothness; 3 - clinical studies that take into account the behavior of the protocols polishing are scarce and should be encouraged; 4 - the large number of variables influence the final outcome of polishing should be considered. Conclusions: The necessity in standardization of methodologies to enable a comparison among researches. (c) 2014 Japan Prosthodontic Society. Published by Elsevier Ireland. All rights reserved.

Efeito de intervenções não farmacológicas nos níveis de estresse em cuidadores de pacientes com doença de Alzheimer: uma revisão sistemática

Beside aging process comes the incidence of dementia and, among them Alzheimer's disease (AD) accounts for approximately 60% of cases. This disease is characterized as a neuropathology with unknown etiology that causes cognitive deficits and behavioral disorders. Caring for patients with AD can cause an overload, both physical and psychological, which can cause high levels of stress on the primary caregiver. It is necessary that the caregiver also receives attention and develop activities that promote health benefits, while providing moments of distraction from the task of caring. Nonpharmacological interventions may be favorable for improving health with consequent decreased on the levels of stress. The objective of this study was to conduct a systematic review of scientific papers that aimed to verify the effect of nonpharmacological interventions on stress levels in caregivers of patients with AD. To contamplate this goal was accomplished a systematic search in the following databases: Biological Abstracts, PsycINFO, PubMed/Medline, Web of Science, LILACS and SciELO. The following keywords and Boolean operators was used: “caregivers” OR “family” and “nonpharmacological interventions” OR “support groups” OR “therapies” AND “Alzheimer's disease” OR “Alzheimer's dementia” OR “Alzheimer” OR “elderly” AND “stress”. There were found 3studies that met inclusion criteria adopted for the present work, and none showed significant results for the variable stress. It is not possible to affirm, according to the studies, that nonpharmacologial interventions programs for caregivers of patients with AD are effective to influence and to control the stress. However, studies show benefits for other variables such as self-efficacy and confidence in relation to care... (Complete abstract click electronic access below)

Enfermagem e o gerenciamento de custos: revisão sistemática nacional e internacional

Objectives: conduct a systematic review of national and international literature, to classify the types of production, comparing the two literatures and synthesize knowledge in the area. Method: Systematic Review of Literature, in the databases LILACS, CINAHL and MEDLINE for selection of articles in their entirety, the data extracted from the articles selected were: the study of bibliographic information (title, author, journal, place of study and year of publication), and general information (multidisciplinary production or specific area, language, type of study, type of population and contributions of the study). The categories established for classification of publications were: raising the cost of procedures/ interventions, economic evaluation of specific intervention, inclusion of nursing in the economic context, using cost as an important variable in the study. Results: The study included 39 publications, with 31% of national production and the remaining 69%, internationally. Most publications were classified according to category of economic evaluation of specific intervention, followed by the category of raising the cost of procedure / intervention, which fits the majority of national production. Human resources is shaped as an important variable for obtaining cost studies that proposed to make this calculation. Conclusion: The production of literature in nursing cost management is relevant in number of publications within the proposed period and is directed to different areas within this theme. There are significant differences in national and international literature: these last use more accurate methods, have more content theorized, use more the economic evaluation tools and related more costs with a amplified context. The production of such knowledge should continue as far as possible and putting that knowledge relating the current reality, in order to amplify the field of nursing and add value

Photodynamic antimicrobial chemotherapy for prevention and treatment of dental caries: a critical review

Introduction: Photodynamic antimicrobial chemotherapy studies regarding dental caries have been present more frequently in the literature. However, photodynamic antimicrobial chemotherapy depends on the adjustment of variables such as the type of light source and, photosensitisers target microorganism; this makes it difficult to draw meaningful comparisons. The purpose of this paper was to provide a critical review related to this coadjuvant approach in the prevention and treatment of dental caries. Materials and Methods: A database search was made via Medline/PubMed (keywords: photodynamic therapy and dental caries) and 33 articles were found. Results: Twelve articles were included after using the filter tool, being excluded reviews and manuscripts reporting works not related to the studied area. Conclusion: The manuscripts showed that photodynamic therapy presents optimal results against dental caries, even though better understanding of photodynamic antimicrobial chemotherapy and its components are necessary before the clinical application of this alternative modality in the dental practice.

Avaliação das alterações dentárias e esqueléticas induzidas pelo uso do aparelho de Herbst no tratamento da classe II na dentadura mista: Revisão sistemática

Objective: evaluate the immediate dental and skeletal changes induced by the Herbst appliance on early treatment of Angle´s Class II malocclusion. Material and Method: several electronic databases such as Scopus, Pub Med, Medline, Cochrane Library, Lilacs and Scielo were searched. The abstracts that fullfilled the selection criteria were selected and those that did not provide enough information about these criteria were selected but the final decision of including them or not on the research, was taken after the complete reading of the article. The selection criteria were: clinical studies with Class II individuals, both male and female, with initial age of 7 to 10 years, treated with the Herbst appliance that analysed the dental and/or skeletal changes evaluated on lateral cephalometric radiographs; researches where the treatment performed did not involve extractions or surgical interventions; studies that included patients without syndromes or health concerns and articles published in English or Portuguese. Results and Conclusions: five articles were selected. The articles showed that significant changes happened in the mandibular sagittal lenght, on facial convexity angle, on maxillo-mandibular relationship, on retroclination of the upper incisors and on distal movement of the upper molars, on proclination of the lower incisors and on extrusion of the lower molars. The appliance exerted a limited effect on the anterior relocation of the maxillary complex and on facial heights. However, more studies about the performance of the Herbst appliance on early treatment of Class II are needed.

Cariogenicidade do leite materno: mito ou evidência científica

Introduction: Breast-feeding has stood out as health care measure and is part of the Government’s National Health Policy, involving dental professionals. However, it has been suggested that breast milk could be a risk factor for the development of early childhood caries. Objective: The purpose of this report was to search for scientific evidence that would support or refute the statement that breastfeeding is associated with the development of early childhood caries. Method: Medline and SciELO databases were consulted to retrieve studies, ranging from laboratory investigations to epidemiological surveys, which relate breastfeeding to dental caries. The key words ‘breast-feeding’ and ‘dental caries’ were used on the reference search. There was no scientific evidence that could demonstrate a clear relationship between breast milk and cariogenicity. This is attributed to fact that dental caries is a multifactorial disease that is susceptible to multiple confusing factors, among which the early introduction of sucrose to the infant’s diet and late introduction of oral hygiene habits. The dentist should encourage exclusive breast-feeding because, in addition to the undeniable benefits to the child’s physical and psychological health, it contributes to a harmonic facial growth and prevents the development of atypical deglutition and malocclusions, in combination with early introduction of oral hygiene habits and noncariogenic diet. Conclusion: There is no scientific evidence to demonstrate an association between breast-feeding and early childhood caries.

Extensão universitária e trabalho voluntário na formação do acadêmico em odontologia

The aim of the present study was to point out the importance of the experience of undergraduate dental students in extra-curricular activities and volunteer work, as a means through which to gain essential knowledge and abilities for their professional lives. A literature review of the Medline, Scielo, and Lilacs databases was carried out in an attempt to select articles related to the university extension and volunteer work of undergraduate dental students. It is still extremely difficult to include university extension and volunteer work as an important activity in Dentistry courses. However, the presentday work market demands professionals who have expertise not only in dental techniques, but also in the socio-cultural characteristics of communities, considering that people need to be comprehensive in their psychosocial aspects in order to be treated as a complete professional. Therefore, university dentistry courses should give equal consideration to both oral rehabilitation skills and the promotion of general healthcare, acquired mainly through extracurricular activities, in an attempt to redeem the integral education of the healthcare professional. Moreover, students should pay closer attention to the opportunities offered during their undergraduate courses, as the work market for dentists is becoming more and more competitive. Moreover, the dentist whose professional life is limited to the dental office will most certainly forgo the opportunity to act in other social areas as well as the recognition that comes with such acts.
