A preliminary scanning electron microscope examination of wear striation direction on primate teeth.
Wear striations experimentally produced on initially unworn teeth were examined at high magnification using a scanning electron microscope. Certain characteristics of individual wear striations on these teeth indicate the direction of motion that produced them. Other striations on worn teeth of American Indians and the Paleocene primate Phenocolemur show similar characteristics and correspond t...
متن کاملWear striation direction on primate teeth: a scanning electron microscope examination.
Two experimental methods were used to produce wear striations in one direction on unworn teeth. These include: (1) sliding 22 American Indian (Juntunen site, Michigan; Late Woodland) newly erupted incisors, by hand, across a flat grass surface covered with fine loose sand; and (2) using a unidirectional motor driven mechanical wear machine to draw 56 modern human dental extractions across a fla...
متن کاملDental Wear: A Scanning Electron Microscope Study
Dental wear can be differentiated into different types on the basis of morphological and etiological factors. The present research was carried out on twelve extracted human teeth with dental wear (three teeth showing each type of wear: erosion, attrition, abrasion, and abfraction) studied by scanning electron microscopy (SEM). The study aimed, through analysis of the macro- and micromorphologic...

15 صفحه اولA Scanning Electron Microscope Examination of Heligmosomum costellatum
The morphology of Heligmosomum costellatum, a nematode of field mice (Microtus epiraticus), was described by scanning electron microscope. The scanning electron microscopic view of this nematode revealed that the anterior end was surrounded by 2 cephalic vesicles. The 2 copulatory spicules of the male were enveloped in membrane and the male bursa was large. The female posterior end was characte...
