Scanning electron microscopic and profilometric study of different sharpening stones
(2006-12-01)
Scaling and root planing contribute to the recovery of periodontal health. All periodontal instruments loose their fine cutting angle after use. To maintain this angle, correct sharpening is required using specifically ...
Flexibility and torsional resistance of three nickel-titanium retreatment instrument systems
(2011-08-01)
Aim To assess the dimensional characteristics, flexibility and torsional behaviour of nickel-titanium retreatment instruments. Methodology Using image analysis software and high-resolution digital images, the instrument ...
Micro-CT assessment of two different endodontic preparation systems
(2013-01-01)
The aim of this study was to compare two endodontic preparation systems using micro-CT analysis. Twenty-four one-rooted mandibular premolars were selected and randomly assigned to two groups. The samples (n = 12) of Group ...
