Intraoral radiograms can be made according to the long tube paralleling technique utilizing aiming devices. An important factor in the design of these instruments is the length of the teeth to be radiographed. Reliable data regarding the length of the teeth in the different regions of the mouth are not available. Information on the length of teeth was therefore collected by measuring 1,400 extracted teeth. A statistical analysis of the data finally resulted for each region of the mouth and for both sexes in length value which could be used for the design of aiming devices.
口腔内X光片可根据使用定位装置的长管平行技术来拍摄。这些仪器设计中的一个重要因素是要拍摄牙齿的长度。目前尚无关于口腔不同区域牙齿长度的可靠数据。因此，通过测量1400颗拔除的牙齿收集了有关牙齿长度的信息。最终，对这些数据进行统计分析，得出了口腔各区域以及男女两性的长度值，这些值可用于定位装置的设计。
