A preliminary scanning electron microscope examination of wear striation direction on primate teeth.
نویسنده
چکیده
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 to mandibular movement during mastication.

Wear 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 کاملPostcanine Tooth Function and Jaw Movement in the Gomphodont Cynodont
The postcanine dentition of Diademodon was well adapted, in both morphology and pattern of replacement, to exercising and maintaining precise occlusion. These teeth may be grouped into three morphological classes, consisting of conical, gomphodont and sectorial teeth. The anterior conicals may have acted as gripping teeth, and the posterior sectorials may have been utilized as food "tenderizers...
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...
متن کاملInvestigation on the Tribological Behavior and Wear Mechanism of Five Different Veneering Porcelains
OBJECTIVES The primary aim of this research was to investigate the wear behavior and wear mechanism of five different veneering porcelains. METHODS Five kinds of veneering porcelains were selected in this research. The surface microhardness of all the samples was measured with a microhardness tester. Wear tests were performed on a ball-on-flat PLINT fretting wear machine, with lubrication of ...
متن کاملDry and Wet Wear Characteristic of TiO2 Thin Film Prepared by Magnetic Sputtering in Ringer Solution
In this research, a thin film of TiO2 was applied on AZ91D using the method of magnetic sputtering. Microstructure investigations were done using field emission scanning electron microscope (FESEM) and X-ray diffraction (XRD). Wear resistance for the coating was investigated using the pin on the disk in the form of dry and in the Ringer's solution. After this test, the worn surface of the sampl...
