This article introduces the interactive computer application program EPIX and the associated personal computer/digitizer system. The system is used to measure marginal alveolar bone height and to record angular alveolar bone defects, defective margins of dental restorations and dental calculus from 5 X-magnified periapical radiographs in cross-sectional epidemiological investigations. The 134-kBytes compiled BASIC program provides 17 menu options. A complete recording of interproximal tooth surfaces takes on average 20 minutes per subject. Data from 200 subjects can be stored on one 5.25" floppy disk. EPIX transforms data files into text files to enable transfer to main-frame computer for statistical analyses. Data displays on VDU or paper are available. Routines for data location and processing, file processing and visual display of an operator's manual provide additional facilities. EPIX has been used to process an epidemiological material of 912 subjects and has proved to be useful.
本文介绍了交互式计算机应用程序EPIX及相关的个人计算机/数字转换器系统。该系统用于在横断面流行病学调查中，从5倍放大的根尖X线片中测量牙槽嵴顶骨高度，并记录牙槽骨角形缺损、牙齿修复体的缺损边缘和牙结石。这个134千字节的编译BASIC程序提供了17个菜单选项。每位受试者平均需要20分钟才能完整记录邻面牙表面情况。200名受试者的数据可以存储在一张5.25英寸软盘上。EPIX将数据文件转换为文本文件，以便传输到大型计算机进行统计分析。数据可以在视频显示器或纸上显示。数据定位与处理、文件处理以及操作员手册中的视觉显示例程提供了更多功能。EPIX已用于处理912名受试者的流行病学资料，且已证明其有用性。
