Abstract
Exposure of white rats to vibration of [plus or minus] 0.05 inch amplitude at a frequency of 2600 cycles per min., 8 hrs. daily, 6 days/wk., for 28 days, did not affect the rate of growth of the incisor teeth, or the calcification of the dentin as shown by the constant avg. width and number of measurable dark plus light incremental rings in the dentin. Histologic examination of the dentin, pulp, alveolar periosteum, alveolar bone, and the structures, of the tempo-romandibular articulation failed to disclose any greater variation of cellular changes than occur normally.
