In the present study the reproducibility of horizontal dimensions and of overlappings of two filmholder techniques with aiming devices (Eggen-bite and Kwik-bite) and additionally the number of overlappings on the resulting bitewing radiographs were compared. The overlapping reproducibility was significantly higher with Kwik-bite. The microdensitometric reproducibility demonstrated the same tendency, but the result was not significant. Bitewings carried out by an oral radiologist demonstrated fewer overlappings with Eggen-bite than with Kwik-bite, while bitewings carried out by inexperienced students revealed no difference between the methods. Both reproducibility and number of overlappings should be taken into consideration when bitewing filmholder techniques are used in epidemiological and longitudinal studies.
在本研究中，比较了两种带有瞄准装置（Eggen-bite和Kwik-bite）的胶片夹技术在水平尺寸和重叠情况方面的可重复性，此外还比较了由此产生的咬合翼片X线片上的重叠数量。Kwik-bite的重叠可重复性显著更高。显微密度测定的可重复性也显示出相同趋势，但结果不显著。由口腔放射科医生进行的咬合翼片检查显示，使用Eggen-bite时的重叠比使用Kwik-bite时少，而由缺乏经验的学生进行的咬合翼片检查则显示两种方法之间没有差异。在流行病学和纵向研究中使用咬合翼片胶片夹技术时，应同时考虑可重复性和重叠数量。
