scanning electron microscopy study of dental gutta-percha after cutting
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...
متن کاملScanning Electron Microscopy of Dental
Dental calculus, a type of stone formed even under normal conditions, plays an important role in some periodontal diseases. Deposition of dental calculus follows plaque formation, and the variations in the degree of calcification reflect the changes in environment and form of its lamellar structure[1]. Dental plaque is composed of rods, cocci and filamentous bacteria[2], and these morphological...
متن کاملEffect of Repeated Sterilization Cycles on the Physical Properties of Scaling Instruments: A Scanning Electron Microscopy Study
BACKGROUND Repeated sterilizations cycles cause undesirable alterations in the material properties of the instruments, such as corrosion, alterations in the hardness of the metal and the loss of the cutting sharpness of the instrument. This research examined the effect of repeated dry heat sterilization and autoclaves cycles on carbon steel (CS) and stainless steel (SS) curettes during the scal...
متن کاملpreliminary study of in vivo formed dental plaque using confocal microscopy and scanning electron microscopy
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...
