The purpose of our study is to determine whether bucco-palatal/lingual (BPL) root dilacerations (RD), especially in single root teeth, can be determined using the ImageJ program through only one periapical radiography. Extracted teeth without any RD ( = 8) were determined as the control group (Group 1) and with RD in apical 1/3 part at least 20° with the longitudinal axis in the BPL direction ( = 8) as the study group (Group 2). With the help of a simple holder system prepared, digital periapical radiographs of all teeth were taken in an anteroposterior position. Histogram analysis of all periapical radiographs was performed using the spectrum feature of ImageJ software. It was aimed to make a dilaceration analysis by comparing the groups using mean, standard deviation, minimum, maximum, and bin width values. As a result of the Mann-Whitney test, all mean and maximum values showed a statistically significant difference between the study and control groups ( < 0.05). This pilot study revealed that the ImageJ software can be used to diagnose BPL dilaceration in the apical 1/3 part of the root. It is important for dentists and patients that it can contribute to limiting the radiation dose to which patients will be exposed.
本研究的目的是确定是否可以仅通过一次根尖射线照相,使用 ImageJ 程序来确定颊-腭/舌(BPL)根扭转(RD),特别是在单个根牙中。无 RD 的拔除牙( = 8)被确定为对照组(第 1 组),而至少有 20°的根尖 1/3 部分且 BPL 方向的长轴与 RD 方向一致的牙( = 8)被确定为研究组(第 2 组)。借助于制备的简单夹持系统,对所有牙齿进行了前后位的数字化根尖射线照相。使用 ImageJ 软件的光谱特征对所有根尖射线照片进行了直方图分析。目的是通过比较各组的均值、标准差、最小值、最大值和箱宽值来进行扭转分析。Mann-Whitney 检验的结果表明,研究组和对照组之间所有的均值和最大值均存在统计学差异( < 0.05)。这项初步研究表明,ImageJ 软件可用于诊断根尖 1/3 部分的 BPL 扭转。对于牙医和患者而言,重要的是它可以有助于限制患者接受的辐射剂量。
