摘要/Abstract

摘要： 目的　分析偏侧咀嚼诱发因素去除之后的咀嚼功能改善情况。方法　采用口腔专科检查和问诊相结合的方法随机选择30例偏侧咀嚼患者（男女各半），年龄（19.3±0.5）岁，为实验组，其中左偏侧咀嚼者13人，右偏侧咀嚼者17人。实验前已去除造成偏侧咀嚼的常见诱发因素。用吸光度法分别检测在随意咀嚼、左侧咀嚼、右侧咀嚼三种咀嚼方式下的吸光度值，并进行比较分析。同时随机选择双侧咀嚼组为正常对照（n=30, 男女各半），年龄（19.6±0.3）岁。结果　实验组的吸光度值与对照组比较有显著性差异（P＜0.01），但两组中男、女间吸光度值均无显著性差异（P＞0.05）。同时，在实验组中，左偏侧咀嚼者的随意咀嚼与左侧咀嚼吸光度值无显著性差异（P＞0.05）,但均高于右侧咀嚼的吸光度值（P＜0.05）；而右偏侧咀嚼者的随意咀嚼与右侧咀嚼吸光度值无显著性差异（P＞0.05）,但均高于左侧咀嚼的吸光度值（P＜0.05）。结论　偏侧咀嚼患者在诱发因素去除之后对其测定的咀嚼效率仍低于双侧咀嚼者，提示常规的去诱因治疗不能真正达到恢复双侧咀嚼功能的目的，有必要考虑给予干预治疗。

Abstract: Objective　To analyze the possible function improvement after removal of inducing factors for unilateral mastication. Methods 　As the experimental group, 30 patients with unilateral mastication (male or female) were randomly selected by adopting the methods of combining clinical stomatology examination with inquiry, including 13 cases with left side chewing and 17 cases with right side chewing. The common inducing factors for unilateral mastication had been removed before the experiment. The absorbance value was tested and analyzed to compare masticatory efficiency under the circumstances of random chewing, left side and right side chewing respectively. Bilateral chewing people were randomly selected as the normal control (n=30, male or female). Results　There was significant difference in absorbance value between the experimental group and control group (P<0.01), while no significant difference was found between male and female cases in each group (P>0.05). In the experimental group, although there was no significant difference in absorbance value between random chewing and left side chewing for left side chewing people (P>0.05), each of them was higher than that of the right side chewing (P<0.05). Moreover, no significant difference was found between random chewing and right side chewing (P>0.05), but each of them was higher than left side chewing (P<0.05) for right side chewing people. Conclusions　After the removal of inducing factors for unilateral mastication, the masticatory efficiency of unilateral mastication cases is still lower than bilateral chewing group, suggesting that the conventional removal of inducing factors for unilateral mastication can not really achieve the purpose of restoring bilateral masticatory function, and a therapeutic intervention may be necessary as well.
