Spee曲线高度与咀嚼效率的相关性研究

To study the relation between the height of Spee curve and masticatory efficiency

目的:研究Spee曲线高度与咀嚼效率的相关关系。方法:测量203名在校大学生的咀嚼效率和Spee曲线高度,将结果进行Pear son相关性检验,以P<0.05为差异有统计学意义。结果:Spee曲线高度在0到2mm范围内与咀嚼效率呈显著正相关,r=0.631,P<0.01;Spee曲线高度在2到5mm范围内与咀嚼效率呈显著负相关,r=-0.759,P<0.01。结论:当Spee曲线高度在2-2.5mm范围内时,咀嚼效率最大,过大或者过小的Spee曲线高度都有可能降低咀嚼效率。

Objective： To evaluate the correlation between the height of Curve of Spee and masticatory efficiency. Methods： The masticatory efficiency and height of Curve of Spee of 203 college students were measured, and analyzed by using the Pearson correlation test. The statistical significance level is 0.05. Results： The height of Curve of Spee within the range of 0 to 2 mm was positively related to the masticatory efficiency （r=0.631 and P〈0.01）; the height of Curve of Spee within the range of 2 to 5mm is negatively correlated to the masticatory efficiency （r = 0.631 and P〈 0.01）. Conclusion： With the height of Curve of Spee within the range of 2-2.5mm, the masticatory efficiency reaches the highest, the masticatory effi- ciency decreases with the height of Curve of Spee beyond the range of 2 to 2.5mm.
