4·Some level of residual stresses in periodontal ligament was left after one mastication period.
一个咀嚼周期结束后，牙周膜有残余应力存在。
5·Furthermore, it can also stimulate proliferation and differentiation of periodontal ligament cell.
它还可诱导牙周膜细胞的增殖和分化。
6·The stress in the periodontal ligament near apex increased more rapidly than that near the alveolar bone crest.
