rom the point of view of deontological ethics, privacy is a moral right that patients are entitled to and it is bound to professional confidentiality. Otherwise, the information given by patients to health professionals would not be reliable and a trustable relationship could not be established. The aim of the present study was to assess, by means of questionnaires with open and closed questions, the awareness and attitudes of 100 dentists working in the city of Andradina, São Paulo State, Brazil, with respect to professional confidentiality in dentalpractice. Most dentists (91.43%) reported to have instructed their assistants on professional confidentiality. However, 44.29% of the interviewees showed to act contradictorily as reported talking about the clinical cases of their patients to their friends or spouses. The great majority of professionals (98.57%) believed that it is important to have classes on Ethics and Bioethics during graduation and, when asked about their knowledge of the penalties imposed for breach of professional confidentiality, only 48.57% of them declared to be aware of it. Only 28.57% of the interviewees affirmed to have exclusive access to the files; 67.14% reported that that files were also accessed by their secretary; 1.43% answered that their spouses also had access, and 2.86% did not answer. From the results of the present survey, it could be observed that, although dentists affirmed to be aware of professional confidentiality, their attitudes did not adhere to ethical and legal requirements. This stand of health professionals has contributed to violate professional ethics and the law itself, bringing problems both to the professional and to the patient.
Dental materials are developed as general materials for specific aplication in oral environment. To determine the functional properties of these materials, nonstandard approach and specific methods need to be utilized. In this study, two methodologies of material testing were used – artificial aging and quanti- fication of visual informations for life circle assesment of hydroxyapatite (Hap) based materials. Hap was chemically synthetized, resulting in high purity and crystallinity of the material. Artificially produced Hap is used in stomatology for repair of bone tissue, as a filling for periodontal defects, and as a preservative augmentation for alveolar ridges. These materials are also used for definitive root canal obturation in endodontic therapy procedure as an apical plug or as complete filling material. This research study was focused on the analysis of the bonding properties of Hap-based materiales to the root canal walls. The methodology of artificial aging was used together with the quantification of vi- sual informations for the purpose of quantifying the Hap bonding properties and bonding quality. Experiments were done in vitro, with the artificial saliva as the agressive agent. The experimental teeth were analysed by a high reso- lution optical microscope for the morphological characterisation of the bonding layer. A model for the bond life circle assesment was developed. Hap-based materials showed favorable properties for dental use. The presented results proved that the combination of the two methodologies (artificial aging and quantification of visual informations) could be used as a tool for analysing the material-dentine interaction.
dentists working in public indicated ‘Lack of time’ as a barrier, while ‘Limited guidelines available in the dental field’ and ‘Clinical guidelines being perceived as restricting the clinical freedom of dentists’ was indicated mostly by specialist, dentists working in public practice, and academics (p < 0.05). Regardless of demographic variables, more than 75% of dentists believed that ‘dental faculties and NDAs could collaborate for developing CG’ and more than 80% believed that they could collaborate for effective dissemination of CDGs. However, there were differences based on age, gender and type of practice, regarding the developing and disseminating body (E.g. universities, NDAs, ‘joint activity of various dental bodies’) and the duration of the validity of CDGs (in years) (p < 0.05). Although ‘when new evidence becomes available’ was the main answer with no impact of age and years in practice (p > 0.05), there was a difference between dentists working in private practice and university members compared to other modes of practice (p < 0.05) regarding the appropriate time for update.
(usually including and under dental anaesthesia) are usually discussed (1, 3, 5). When choosing a drug for premedication it is of a great importance to know the benefits, the contraindications and the possible side effects that must be complied with the general condition of the patient (4,5,6). Some of the most commonly prescribed schemes we proposed and presented in two categories: non-allergic patients negative to skin testing to local anesthetics and non-allergic patients positive to skin testing.
Abstract: Investigating career motivations and intentions of dental students provides a better understanding of their role in society and contributes to the debate on dental education and practices. This study describes the proile, career choice motivations, and career intentions of Brazilian dental students and evaluates factors related to these choices. A cross-sectional study was car- ried out among dental students from three Brazilian public universities (N=915), with a response rate of 83.7 percent. Students (N=766) responded to a self-administered questionnaire about sociodemographic factors, reasons for choosing dentistry as a career, and future career intentions. Job conception was found to be the main reason for choosing dentistry as a profession. Most students intended to become specialists and work in both the public and private sectors simultaneously. Female students (OR 2.23, 95 percent CI=1.62-3.08), low-income students (OR 1.86, 95 percent CI=1.10-3.13), and students beginning their program (OR 1.87, 95 percent CI=1.22-2.85) were more likely to work in the public and private sectors simultaneously than other types of students. This study suggests that choice of career and career plans are inluenced by factors related to the students’ character- istics and their conception of the profession. The opportunity to combine private and public dentalpractice may be viewed as a way to achieve income and job security.
A cross-sectional study was conducted to collect data among dentists in Xi’an from April to June 2013. There are three types of dentalpractice in China. These include: dental hospital, de- partment of dentistry in general hospital and dentistry. Stratified cluster sampling (by type of practice) was used to select participants. Firstly, practices from a list of all dental practices in Xi'an provided by Shaanxi Stomatological Association were divided into three groups accord- ing to their types. Next, practices were selected randomly in every type, and then all dentists worked in these selected practices were intended to be surveyed. The dentists were adminis- tered surveys in their office between seeing patients. Investigators were trained graduate stu- dents. An investigation team including two investigators was responsible for a district. When the dentists finished the questionnaire, the investigators checked whether all the questions were answered, if not, they would remind the dentists to finish all the questions.
The four processes responsible for the largest portion of waste and pollution from dentalpractice are: use of materials containing mercury (amalgam fragments and waste — mercury vapor release); conventional X-ray systems (equipment, film, sil- ver fixer, insoluble developer solutions); infection control methods including disposable barriers, toxic products for sterilization and disinfectants; conven- tional vacuum saliva suction systems. 8,9 Thus, green
Bajkin B.V. et al. in a study on 213 patients evaluated the effects of combined oral anticoagulant-aspirin therapy in patients undergoing tooth extractions. Patients were divided into three groups of 71 participants each. Patients in group A received combined anticoagulant-aspirin (100-milligram prophylactic dose) therapy. Patients in group B received oral anticoagulant therapy. Patients in group C received aspirin therapy (100-mg prophylactic dose). Bleeding was marked as an Event if it met the following criteria: the bleeding continued beyond 12 hours, patient had to call the surgeon or return to dentalpractice or emergency department, bleeding resolved with large hematoma or ecchymosis within the oral soft tissues or required a blood transfusion. The authors found no statistical significance in postoperative bleeding between these three groups. All cases of hemorrhage were controlled easily by using local hemostatic measures. 47
For many years, chemical properties were re- sponsible for the selection of materials used in dentalpractice. This paradigm was already pre- sent in the primitive dental prostheses made by the Etruscans. Mechanical properties were decisive in the predominant use of dental restorations based on silver amalgam, described by G. V. Black (1896), from the early 20th centu- ry until the mid-1980s. Proof of this trend is that the American Dental Association, one of the first associations to establish standards to specify the basic composition and properties of dental materials, published Guideline no. 1 in 1927 (Phillips, 1986). This standardization focused only on satisfactory mechanical prop- erties for a given material to be used as a den- tal amalgam.
There are several variables in the studies concern- ing ceramic bracket removal by lasers, such as: laser settings, type of brackets and bonding agents, as well as the employed methodology. Therefore, in view of the increased use of ceramic brackets in orthodon- tic patients and the improvements in laser technology and adhesive dentistry in dentalpractice, the aim of the current investigation was to assess in vitro the in- fluence of CO 2 laser use and of the type of ceramic bracket on the shear bond strength (SBS) to enamel. The null hypothesis tested was that the CO 2 laser ir- radiation does not decrease SBS values of the evaluat- ed polycrystalline ceramic brackets.
nas superiores na conservação da estrutura dental, uma vez que se torna desnecessário sacrificar cúspides para proteger o remanescente dental como se faz nas restaurações metálicas, devido à característica de reforço da técnica de cimentação adesiva. Entretanto, alertaram para as diferenças entre os preparos das inlays estéticas e das restaurações metálicas indiretas, considerando a preparação para as inlays estéticas bem mais fáceis de serem executadas. Comentaram que as paredes da cavidade devem divergir de 10 a 15º e os ângulos internos devem ser arredondados para permitir um melhor assentamento e evitar a concentração de tensão. As margens podem ter chanfros profundos, mas não bisel. A profundidade de desgaste deve ser de no mínimo 1,5 a 2 mm e a largura do istmo deve estar em torno de 2 mm. Advogou o uso do cimento de ionômero de vidro como base e enfatizou que os cimentos provisórios não devem conter eugenol, para não interferir na polimerização do cimento resinoso.
that serves especially young individuals aged between 14–30 years in Ankara, Turkey. Some of the patients waiting for dental care in the lounge refused to participate due to not having suficient time or not agreeing to ill out the questionnaires. Hence, 607 participants were enrolled in the study. Participants getting treatment for any psychiatric disorders in their medical histories were excluded from the study. All recruited patients gave informed consent after hearing about the aims and procedures involved in the study. Ethical approval was taken from the institutional ethics board.
the positive impact of PHC on health conditions and equity in health care, including a review of the results of FHS in Brazil, and has stated that stronger primary care should produce better outcomes than weaker primary care. This study tested the hypothesis that, in addition to individual socioeco- nomic and psychosocial determinants, inequalities in the use of public dental services for Brazilian low-income preschool children are mediated by the quality of the primary care system. Thus, oral health services with high PHC attributes should favor dental visits for children and would have the potential to minimize the social gradient in access.
Results: With regard to theoretical preparation in emergency situations 72.8% of the students assess the dental education as excellent, 11.8% of the students assess their knowledge as satisfactory and 15.4% of the dental students find difficulties to differentiate the emergency situations. No one of the students is feeling able to manage in those situations.
The practice-based studies assume that the social is not just related to human beings, but also symbolic and cultural artifacts. The notion of practice is rich, as you articulate the notion of space-time of what the actors do, it means, specific practices that involve uncertainties, conflicts and inconsistencies, which are intrinsic characteristics of these practices, enabling considerable insights and contributing to the understanding of the dynamics of an organiza- tion, as well as a course of changes inside a social system (Antonello & Godoy, 2009). Since knowledge is connected to what is done/practice, Cook and Brown (1999) point out that the epistemology of practice is able to convey the coordinated activities of an individual and groups at the moment of their tasks, considering the particular context of the individual and the organization.
In the present era of rapidly evolving technology and evidence based medicine, Good Laboratory Practice (GLP) shall play an important role in ensuring, consistency, reliability, reproducibility and quality of laboratory tests. It provides a frame work for laboratories to plan, perform, monitor, record and report their activities. It also reflects the quality of laboratory services during any assessments and accreditation process. The quality assessment statement is not GLP of compliance statement. The poor laboratory practice found were. 1
irradiação por luz halógena em clareamento a base de peróxido de hidrogênio (HP), avaliar as concentrações HP, eficácia do clareamento dental e as variações de temperatura dos agentes clareadores nas câmaras pulpares. Dezesseis pré-molares foram divididos aleatoriamente em dois grupos: Grupo BL (agente de clareamento com irradiação por luz halógena por 3 × 10 minutos) e Grupo B (somente o agente de clareamento). Concentrações de HP foram testadas antes e após o tratamento. Os valores de CIE L * a * b * das amostras foram obtidos utilizando um espectrofotômetro. Temperaturas dos géis clareadores e das câmaras pulpares foram mensuradas por um multímetro digital com K-tipo de termopar. Os dados foram analisados por ANOVA e teste t pareado. Após o tratamento, a HP concentração no grupo BL foi ligeiramente mais elevada do que no grupo B. O teste t pareado revelou diferenças significativas entre os grupos BL e B em todos os intervalos de tempo. O aumento da temperatura dos géis clareadores e das câmaras pulpares no grupo BL foi significativamente maior do que no grupo B. Os autores concluíram que clareamento de consultório foi eficaz para clareamento dental. O envolvimento de luz halógena foi benéfica para o efeito de clareamento imediato, mas teve pouco impacto sobre o efeito de clareamento a longo prazo.
During the bell stage, we observed in the enamel organ a conspicuous labeling of the cytoplasm and nucleus of the cells of the outer enamel epithelium, stellate reticulum and stratum intermedium (Fig. 1-B, C). However, some cells did not label for DMP1 in the internal dental epithelium (Fig. 1C) and cervical loop region (future root area) (Fig. 1D).
in order to start a process of nominating power of attorney. A point to reflect on is that participants with 10 or more years in practice from areas less closely related to mental health believed that they did not have sufficient in- formation to form an opinion. This highlights the need for additional provisions for all specialties. The hypothesis that some professionals are under more pressure to give opin- ions on a patient’s competence to assume responsibilities must be taken into account. Nevertheless, there are stud- ies 12 reporting only moderate agreement among experts in
