92 children(seven years old) were examined in in this study. DMFindex, occlusal plaque index(OPI) and occlusal contact-area index(OCAI) of their first permanent molar were evaluated.Same children were repeatedly examined sfter two yearsStatisticaly significant decreas in mean OPI and increase in mean OCAI were found amang this two years. And high correlation coefficient was detected between OPI and OCAIThese redsult suggested that the plaque on the occlusal surface will removed by the contact of opposit teth in mastication.

在这项研究中检查了92名儿童（7岁）。评估了其第一个永久摩尔的DMFINDEX，咬合斑块指数（OPI）和咬合接触面积指数（OCAI）。该SAME的平均OPI和平均OPI的Sfter SFTER反复检查了SFTER SFTER SFTER SFTER SFTER，平均OPI显着下降，平均OCAI的增加在这两年中被发现。在OPI和OCEATHESE红色之间检测到高相关系数，这表明咬合表面上的斑块将通过咀嚼中对立的TETH接触去除。
