Chronology of permanent teeth mineralization in Brazilian individuals: age estimation tables
CONCLUSION: In the present study, we evaluated the mineralization stages of permanent teeth of Brazilian subjects from digital panoramic radiographs and found no correlation between the chronology of mineralization stages and sex, except for canines. From the obtained results, numerical tables of the chronology of dental mineralization stages were prepared.PMID:36949486 | DOI:10.1186/s12903-023-02837-y (Source: Health Physics)

Athlete's heart or heart disease in the athlete? Evaluation by cardiopulmonary exercise testing
J Sports Med Phys Fitness. 2023 Mar 23. doi: 10.23736/S0022-4707.23.14536-1. Online ahead of print.ABSTRACTRoutine or vigorous training, particularly in competitive and elite athletes practicing dynamic sports, leads to a constellation of structural and functional cardiovascular adaptations, facilitating an increased capacity to deliver oxygen to the working muscles during sustained physical exertion. Cardiopulmonary exercise testing is the most accurate and objective method to assess performance in athletes. Although still underutilized, it provides a window into the unique cardiovascular response to exercise in athletes,...
