Timely extraction of the first permanent molars severely affected in mixed dentition.
Journal of Oral Research, 2019 The aim of this study was to establish a guide for general dentists that allow identifying the ideal moment to extract the first permanent molars with poor prognosis, in the hope of obtaining a spontaneous closure of space, regarding that the first ...

Impact of Surface Roughness on the Yield Drop of Hot‐Rolled AZX311 Mg Alloy
Advanced Engineering Materials, EarlyView.Rough‐surfaced AZX311 Mg alloy samples have significantly lower yield strength than polished ones due to stress concentrators forming at V‐notch irregularities. Surface profilometry confirms higher Ra values for rough samples. Highest hardness values were observed near scratched surfaces, indicating strain localization effects near the rough surface ...

THE FIRST PERMANENT MOLAR [PDF]
JAMA: The Journal of the American Medical Association, 1922 In 1887, Dr. Andrieu of Paris read a paper before the section on dental and oral surgery of the Ninth International Medical Congress, advocating the extraction of the first permanent molars. His argument was based on the fact that 75 per cent, of these teeth decay.

Advanced Engineering Materials, EarlyView.The microstructure of Cr‐rich Cr‐Si‐alloys is maintained by alloying with Ge, Pt, and Mo. The effects of these elements on A15‐phase fraction, partitioning, microstructural stability, grain size, and hardness are combinable. Molybdenum is found to be the most promising alloying element for microstructural stability during high‐temperature exposure.
