The current clinical practice of endodontics involves utilization of a variety of new technological advances and materials. Technologies available for use in endodontic offices today include battery or electric motors using NiTi rotary file systems, new generation of electronic apex locators (EALs), improved digital radiographic sensors, surgical microscopes, and ultrasonic units. The aim of this study was to determine the prevalence and use of newer technologies among Iranian dental practitioners.
The population under study included the dental practitioners participating in the 49th and 50(th) Congress of Dentistry, who were selected with a simple sampling method. Data was collected by questionnaires which were completed by the participants in an anonymous manner. The contingency table and chi-squared test were used for data analysis by SPSS 13.5 software.
A total of 700 dental practitioners participated in the study; NiTi rotary systems were used by 50.1%; electronic apex locators were often employed by 46.3%; 21.7% reported that ultrasonic units were often used. Only 1.1% frequently used surgical microscopes. Males and females differed with respect to the use of newer technologies (P<0.05).
Based on the results of the present study, it seems necessary for dentists to take part in continuing dental education programs related to the newer technologies to improve their knowledge and practice.
目前牙髓病学的临床实践涉及多种新技术进展和材料的应用。如今可用于牙髓病治疗机构的技术包括使用镍钛旋转锉系统的电池驱动或电动马达、新一代电子根尖定位仪（EALs）、改进的数字放射成像传感器、手术显微镜和超声设备。本研究的目的是确定伊朗牙科从业者中较新技术的普及程度和使用情况。
研究人群包括参加第49届和第50届牙科大会的牙科从业者，采用简单抽样方法进行选取。数据通过问卷收集，参与者以匿名方式填写。使用列联表和卡方检验，通过SPSS 13.5软件进行数据分析。
共有700名牙科从业者参与了本研究；50.1%的人使用镍钛旋转系统；46.3%的人经常使用电子根尖定位仪；21.7%的人报告经常使用超声设备。只有1.1%的人经常使用手术显微镜。男性和女性在较新技术的使用方面存在差异（P<0.05）。
基于本研究结果，牙医似乎有必要参加与较新技术相关的继续牙科教育项目，以提高他们的知识和实践水平。
