咬合纸痕尺寸被广泛接受为牙齿有力接触的指标。然而，标记大小仅指示接触位置和表面积，并且不量化咬合力。本研究的目的是确定纸痕的大小和施加在同一牙齿上的力的百分比之间是否存在关系。30名有牙列的女性受试者将牙尖交错成咬合纸条，以标记其上颌后牙的咬合接触，然后拍摄照片。然后每个受试者进行多咬合力百分比的数字化记录。以摄影像素计算每个象限（n = 60个象限）中最大和最暗的咬合纸标记（n = 240个标记）的表面积，并与同一牙齿上存在的力百分比进行比较。回归分析显示牙齿上的力%的双变量拟合（P<0.05）。标记面积与用力百分比之间的相关系数显示出较低的正相关。决定系数显示标记面积和力之间的因果关系较低（r2 = 0.067）。每个象限中最大的纸痕与同一象限中最有力的牙齿匹配的时间只有38.3%。只有62/3%的牙痕表面积可以用咬合力来解释，而大部分牙痕表面积是由与咬合力无关的其他因素造成的。本研究结果显示，以咬合纸痕大小来衡量咬合力，并不可靠。
Articulation paper mark size is widely accepted as an indicator of forceful tooth contacts. However, mark size is indicative of contact location and surface area only, and does not quantify occlusal force. The purpose of this study is to determine if a relationship exists between the size of paper marks and the percentage of force applied to the same tooth. Thirty dentate female subjects intercuspated into articulation paper strips to mark occlusal contacts on their maxillary posterior teeth, followed by taking photographs. Then each subject made a multi-bite digital occlusal force percentage recording. The surface area of the largest and darkest articulation paper mark (n = 240 marks) in each quadrant (n = 60 quadrants) was calculated in photographic pixels, and compared with the force percentage present on the same tooth. Regression analysis shows a bi-variant fit of force % on tooth (P<.05). The correlation coefficient between the mark area and the percentage of force indicated a low positive correlation. The coefficient of determination showed a low causative relationship between mark area and force (r2 = 0.067). The largest paper mark in each quadrant was matched with the most forceful tooth in that same quadrant only 38.3% of time. Only 6 2/3% of mark surface area could be explained by applied occlusal force, while most of the mark area results from other factors unrelated to the applied occlusal force. The findings of this study indicate that size of articulation paper mark is an unreliable indicator of applied occlusal force, to guide treatment occlusal adjustments.
