To make the transition curve in the process of gear modeling be more reasonable, the parameterized 3D model of involute cylindrical spur gears with whole profile was made with Pro/Engineer software, based on the study of equations of the dual-arc rack cutter＇ s profile curves and the cut gear＇ s tooth profile curves.

为了使齿轮建模时过渡曲线部分更符合工程实际，在对双圆弧齿条型刀具轮廓曲线方程和齿轮的廊线方程研究的基础上，利用Pro/Engineer软件建立了可变位的渐开线完整齿廊直齿圆柱齿轮的三维参数化模型，并对齿廊曲线连续性进行了分析。

Results: 1. The three-dimension (3D) model reconstructed by Micro-CT scan data objectively reflected the real contour and the pulp cavity figure of the tooth.

实验结果： 1。本研究采用Micro-CT扫描，准确、安全、无创伤、分辨率高，所得到的断层信息可以较清晰的显示牙体组织及根管系统等结构，又不破坏标本的完整性。

METHDOS: Pulp cavity perforations were created in the pulpal floor of 55 extracted tooth. They were repaired with amalgam、flowable resin、Chinese gall compound recipe under amalgam、Chinese gall compound recipe under resin and MTA. Then the sealing ability of different materials by dye penetration were evaluated.
