Cephalometric norms of McNamara analysis have been studied in various populations due to their optimal efficiency. Dolphin cephalometric software greatly enhances the conduction of this analysis for orthodontic measurements. However, Dolphin is very expensive and cannot be afforded by many clinicians in developing countries. A suitable alternative software program in Farsi/English will greatly help Farsi speaking clinicians. The present study aimed to develop an affordable Iranian cephalometric analysis software program and compare it with Dolphin, the standard software available on the market for cephalometric analysis.
In this diagnostic, descriptive study, 150 lateral cephalograms of normal occlusion individuals were selected in Mashhad and Qazvin, two major cities of Iran mainly populated with Fars ethnicity, the main Iranian ethnic group. After tracing the cephalograms, the McNamara analysis standards were measured both with Dolphin and the new software. The cephalometric software was designed using Microsoft Visual C++ program in Windows XP. Measurements made with the new software were compared with those of Dolphin software on both series of cephalograms. The validity and reliability were tested using intra-class correlation coefficient.
Calculations showed a very high correlation between the results of the Iranian cephalometric analysis software and Dolphin. This confirms the validity and optimal efficacy of the newly designed software (ICC 0.570-1.0).
According to our results, the newly designed software has acceptable validity and reliability and can be used for orthodontic diagnosis, treatment planning and assessment of treatment outcome.
由于麦克纳马拉分析法的测量效率高，因此已在不同人群中对其头影测量标准进行了研究。海豚头影测量软件极大地提高了这种正畸测量分析的操作效率。然而，海豚软件非常昂贵，许多发展中国家的临床医生难以负担。一款合适的波斯语/英语替代软件程序将极大地帮助讲波斯语的临床医生。本研究旨在开发一款价格实惠的伊朗头影测量分析软件程序，并将其与市面上用于头影测量分析的标准软件海豚软件进行比较。
在这项诊断性描述性研究中，从伊朗主要以波斯族（伊朗主要民族）为主的两个大城市马什哈德和加兹温选取了150张正常咬合个体的头颅侧位片。在描绘完头颅侧位片后，分别使用海豚软件和新软件测量麦克纳马拉分析标准。头影测量软件是使用Windows XP系统下的Microsoft Visual C++程序设计的。在这两组头颅侧位片上，将新软件的测量结果与海豚软件的测量结果进行比较。使用组内相关系数测试有效性和可靠性。
计算结果表明，伊朗头影测量分析软件与海豚软件的结果之间具有非常高的相关性。这证实了新设计软件的有效性和最佳效能（组内相关系数为0.570 - 1.0）。
根据我们的结果，新设计的软件具有可接受的有效性和可靠性，可用于正畸诊断、治疗计划制定以及治疗效果评估。
