Considering the role of epidemiological information in planning and effective interventions, the purpose of this study was to systematically review the epidemiology of squamous cell carcinoma in Brazil. We searched the PubMed, LILACS, BBO and Cochrane databases using keywords "oral squamous cell carcinoma", "oral squamous cell carcinoma", "oral squamous cell carcinoma" and their equivalents in English and Spanish, in combination with epidemiology, prevalence, frequency, and Brazil by 2018, excluding studies that did not address the epidemiology of this neoplasm or those conducted in other countries. The mean age of the patients was 56.6 years, with a higher prevalence in males 3.29: 1, mainly located in tongue, 42% and mouth floor 22%. Associated risk factors are tobacco (72.85%) and alcohol (66.65%). It was observed that 47% of patients present with regional metastases at the time of cancer discovery. According to the observed observational studies it can be concluded that the epidemiological data of Brazil are high in comparison to other countries, especially the number of metastases, indicating the late diagnosis of the disease
Introduction: Repetitive Strain Injury (RSI) and Work-Related Musculoskeletal Disorders (WMSD) are considered a public health problem because of their high prevalence in various professions, including dental professionals. Because of poor posture and organization at work, for example, dental surgeons occupy the top spot on sick leave due to temporary or permanent disability, accounting for approximately 30% of the causes of premature abandonment between medical activities.Objectives: To identify the prevalence of musculoskeletal symptoms and their relationship with dentist activity and to evaluate the relationship between symptomatology and laboratory test results.Methodology: A scan was performed, but Scopus, Web of Sciences and Google Scholar indexing databases were used to unite musculoskeletal disorders, dental surgeons, prevalence, laboratory tests. We found 15,000 articles, of which 56 were selected based on the best h index score or Qualis rating on the Sucupira platform.Conclusion: The relationship between musculoskeletal pain and dentist activity is strong and in some cases, these disorders can be detected on laboratory tests.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
