As a consequence of occupational stresses placed on their bodies, oral health care providers (OHP) are vulnerable to musculoskeletal disorders (MSDs). Muscular imbalance, neuromuscular inhibition, and pain and dysfunction may frequently be observed among OHP. Repeated unnatural, deviated or inadequate working postures, forceful hand movements, inadequate equipment or workplace designs and inappropriate work patterns are likely to be the particular risk factors. However, WMSDs are not an avoidable part of OHPs' professional lives. Paying the necessary attention to occupational and individual risk factors, prevalence, symptoms and consequences of WMSDs, and implementing the recommended health and safety measures can enable a long and healthy career. This review essentially aims to provide background information for OHP regarding the magnitude of the problem, particular risk factors and the available recommendations for prevention. 相似文献

BACKGROUND: Volumetric features of gingival crevicular fluid (GCF) are under the influence of many factors, including sampling variables. Standardizing such factors may enable a more precise methodology. Thus, analysis of the possible impact of the clinical periodontal status and the distinct location of sampling sites on fluid volume was performed. METHODS: Clinical parameters were recorded, and fluid samples were obtained from 931 maxillary sites. The potential site-specific volumetric differences among healthy, gingivitis, and periodontitis sites; between multirooted or single-rooted teeth and mesio-buccal or disto-buccal sampling sites; and the correlations between volume and clinical measures were statistically analyzed. RESULTS: Although volume increased in a disease-related pattern (healthy < gingivitis < periodontitis; P <0.05), the distribution range of volume was widespread, with prominent overlaps between the different clinical periodontal conditions. Multirooted teeth presented more fluid volume, and even mesio-buccal or disto-buccal sites exhibited some volumetric differences (P <0.05). Constant correlations between volume and clinical parameters could be observed only at gingivitis sites (P <0.05). CONCLUSIONS: The spectrum of fluid volume is disease related in general. However, the wide range of volumetric distribution, the site-specific nature, and the clear impact of the distinct sampling site on volume are important volumetric features of this biologic fluid. Whenever possible, standardization of the extent of probing depth, degree of gingival inflammation, and distinct sampling area is likely to improve the reliability of GCF methodology. 相似文献

BACKGROUND: During the assessments made at presurgical, surgical, and follow-up phases, the clinician may benefit from a wide array of clinical and/or image-based measures. Because analysis of the potential associations among the various measures could improve the evaluation process for dental implants, this study attempted to determine the potential correlations among peri-implant sulcus fluid (PISF) volume, implant stability, nitric oxide content of PISF, and marginal bone loss. METHODS: Seventeen completely edentulous patients seeking prosthetic rehabilitation were included. Two ball attachment mandibular overdentures were given to all patients, and early- (N = 18) and delayed-loaded (N = 16) dental implants were compared during 24-weeks of follow-up. Resonance frequency analysis (RFA), marginal bone level, and PISF samples were taken for all dental implants. RESULTS: A consistent and negative correlation was observed between RFA measurements and marginal bone level, whereas some correlations also existed between RFA and PISF volume. The pattern of loading seemed to affect the relationship between RFA measurements and marginal bone level and, to a limited extent, the association between PISF volume and nitrite levels. CONCLUSIONS: Where the potential associations among various implant-related measures are concerned, the factors that may affect such associations (e.g., healing and loading) need to be considered. Data arising from the analysis of the associations between the wide arrays of available implant-related measures may improve dental practitioners' assessment concerning endosseous dental implants. 相似文献
