objective: confocal laser scanning microscopy (clsm) is relatively a new light microscopical imaging technique with a wide range of applications in biological sciences. primary value of clsm for the biologist is its ability to provide optical sections from three-dimensional specimen. the present study was designed to assess the thickness content of in vivo accumulated dental plaque using clsm a...

introduction: the aim of this study was to compare several metallurgic properties of neoniti instrument with four other commonly used endodontic rotary files. methods and materials: neoniti a1 (25/0.08), race (25/0.06), mtwo (25/0.06), twisted file (25/0.06) and protaper next x2 (25/0.06) were examined by differential scanning calorimetry (dsc) before and after heat treatment at 500 ° c. x-ray ...

introduction: the purpose of this study was to evaluate the morphologic surface of gutta­percha cones after cutting with different methods. materials and methods: the apical 3 millimeters of forty standardized, gutta-percha cones size 40 were cut off using scissors or a scalpel against a glass slab. the samples were then examined under scanning electron microscopy (sem) for topographic deformit...
