RESUMO
Age estimation is a major challenge in anthropology and forensic odontology laboratories, as well as in judicial settings, as one of the tools used in human identification. The aim of this study was to evaluate the usefulness of age estimation methods based on the accurate measurement of tooth color changes. A systematic review was carried out following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and in compliance with Cochrane criteria recommendations (PROSPERO registration number CRD 42022343371). An electronic search was performed in the following databases: Pubmed, Web of Science, Medline, Current Contents Connect, SciELO, KCI-Korean Journal Database, Derwent Innovations Index and Russian Citation Index. The search strategy yielded a total of 18 articles. A randomized meta-analysis model of the results for the CIE L*a*b* color variables stratified by age (less than 30 years, 30-60 years, 60 years and older) was performed with 9 of the 18 studies included in this systematic review. According to our results, sex and location of color measurement are the most influential factors in color estimation. All studies were carried out in healthy anterior teeth by spectrophotometry as the most commonly used method for color measurement, with CIE L*a*b* being the most commonly analyzed parameters. Studies based on age as a dependent variable showed R2 values between 0.28 and 0.56, being higher in ex vivo teeth. Studies based on age as an independent variable showed R2 values ranging from 0.10 to 0.48. The random model showed high heterogeneity for the L*, a* and b* parameters in all age groups, which is explained by discrepancies in age range and non-standardized conditions for color measurement. This systematic review highlights the need to protocolize age estimation studies that measure tooth color, in order to apply this method in different forensic settings.
RESUMO
This study aimed to analyze the schools that teach ethical and legal aspects within the subject of palliative care in the degrees of medicine and nursing in Spain. MATERIAL AND METHODS: Descriptive Analysis of the palliative care subject and their ethical and legal curricular competencies in the Spanish Nursing and Physicians undergraduate. The training received in legal ethical aspects related to palliative care was compared with the criteria established by the European Association for Palliative Care (EAPC). DATA SOURCES: The National Conference of Nursing Deans, The National Conference of Spanish Medical Faculty Deans and The Ministry of Science, Innovation, and Universities databases were searched. RESULTS: Twenty-one universities have an undergraduate in medicine with palliative care in their curricular training explicitly. The degree in nursing is present in fifty-six universities, palliative care is present in 62.5% of the cases. The degrees of nursing and medicine receive approximately the same level of training in ethical and legal aspects of palliative care. CONCLUSION: The specific training received in ethical and legal issues of palliative care must be improved in medical and nursing to meet the EAPC levels.
