Longitudinal Clinical Evaluation of Undercut Areas and Rest Seats of Abutment Teeth in Removable Partial Denture Treatment

PURPOSE: Adequate preparation of abutment teeth for removable partial denture (RPD) rest seats allows appropriate masticatory force transmission, retention, and stability of supporting structures. It follows that careful preparation will be important for the longevity of the rehabilitation. The present study aimed to clinically evaluate rest seats and undercut areas of abutment teeth in RPD wearers after 2 years of use. MATERIALS AND METHODS: A total of 193 occlusal, incisal, and cingulum rest seats were evaluated in terms of shape, rest adaptation, wear, caries, fractures, and surface type (enamel, composite resin, or amalgam). Two hundred and fourteen undercut areas were evaluated in terms of surface type (enamel or restoration) and integrity. This study was approved by the Research Ethics Committee of the Federal University of Rio Grande do Norte, resolution 196/1996, protocol number 11/05. RESULTS: Intact preparations accounted for 92.2% of the total. Application of the Pearson test (p= 0.289) found no statistically significant differences among the materials on which the rest seats were prepared. For the undercut areas, 20.7% of those obtained on restorative material were nonintact. In addition, Fisher's exact test showed a statistically significant difference (p= 0.001) in surface type; enamel surfaces were shown to be 14 times more stable than restored surfaces. CONCLUSIONS: The results of this study suggest that rest seats are stable, regardless of the material on which they are prepared. Retentive areas were shown to be more stable when they were located in enamel.

O ambiente de trabalho no setor bancário e o bem-estar

Wich the big transformations at the world of labor, thus as the appearing of the negatives psicologicals consequencies? Publications in books and articles about the health of the workers have been seen in the last 40 years, pointing at the increase of occupational ills, increase of the absenteeism, reach the redation between the labor and the family. With the appearing of the neoliberal sistem, changed all the net of relations, thus as the temporary labor contract, the flexibility at the work timetable, and others, that privilege the capitalism, in detriment of the worker health. It was given emphasis to the banking worker, in time that the banks and the banking agencies were one of the departaments that more suffered the impact of the productive restructuring at the last years. 200 bank clerks shared the search, in that 41,9% was female and 58,1% was male, 60,9% presenting a civil state married, following of 28,4% of single. The participants answered the following instruments: Scale of Positives and Negative Kindness, General Health Questionaire GHQ 12, Scale of Organization, Conditions and Labor Relations, Scale of Desire (own authorship), Scale about economic situation and a social-demographic record car. With the objective of trying the instruments of measure, it was checking the psychometric parameter of the search scales. We could verify that it has been more positive than negative ones for the mental health, but it was found some kind of depression and unsatisfied with their lives in some pieces of the sample. We can finally say that the work place has an impact at the mental health of the bank clerks. So, some interventions actions to promote the worker health could be essential

As condições de trabalho na área de saúde e o processo de adoecimento da (o) assistente social

The requirements in the world of work in the contemporary impact on quality of life, health workers in their relations with users and other professionals of the healthcare team. Given this reality, this study discusses the working conditions in health and disease process of (a) having social goals as analyze the implications of working conditions in the disease (the) social workers in state hospitals Metropolitan Region Christmas (NMR); identify the main diseases affecting social workers in hospitals in the SESAP NMR and reveal the relationship between the disease processes of social and working conditions in hospitals in the state NMR. The research was guiding questions to reveal how to configure the work, conditions of work and of the disease process (the) social worker. To grasp the socioeconomic profile of (the) social workers, the characterization of the work, duties and responsibilities in the sociooccupational, factors that interfere with the disease process of (the) social workers of RMN, and actions and investments Policy on Occupational Health RN correlating to illness today is that we set for the unveiling of the movement of the object of study through the methodological approach with documentary research aimed at literature review; extensive direct observation correlated to real life observation and application of 66 (sixty-six) questionnaires. The data from the closed questions were treated using the Statistical Package for the Social Sciences (SPSS). The open questions were transcribed and then analyzed the light of theoretical work on the subject. The research reveals that social workers are subject to conditions and labor relations precarious illness causing health problems because some of these professionals, among them are: stress, allergies and skin conditions or, Read / WMSD among other diseases. Thus, we understand the need for debates about the relationship work (the) social worker and worker health before the contradictions of capital also present in public health services
