Effectiveness of Two Techniques in Removal of Calcium Hydroxide Medicament from Root Canals: An in-vitro Assessment [PDF]
Journal of Clinical and Diagnostic Research, 2018 Introduction: Calcium Hydroxide {Ca(OH)2 } is widely used as intracanal medicament. However, complete removal of Ca(OH)2 is very difficult from canal walls resulting in its residues on canal wall which interfere with bonding of sealers and reduce success

Tribological and dry drilling performance of WS2/Cr-AlCrN coatings
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021 Dry drilling gives a higher request to the anti-friction property of cutting tools. However, most tool coatings commonly have less lubricant effect. In present paper, WS2/Cr layer was deposited on AlCrN layer by a radio frequency magnetron sputtering ...
