Electrical resistance measurements may be used to determine the situation of the pulp horn tips of teeth prepared for crown restorations. The resistance value recorded for these sites of minimum dentin thickness depends on the thickness of the dentin layer and the degree of tooth development. A resistance value of 25 k omega revealed dentin thickness of 0.7-1.45 mm. The teeth of younger patients had thicker dentin layers than those of older patients.
电阻测量可用于确定为牙冠修复而预备的牙齿髓角尖端的情况。记录的这些牙本质厚度最小部位的电阻值取决于牙本质层的厚度和牙齿发育程度。25千欧的电阻值表明牙本质厚度为0.7 - 1.45毫米。年轻患者的牙齿比老年患者的牙齿有更厚的牙本质层。
