Early diagnosis and treatment of periodontitis, which can cause loss of bone support of the teeth, is of great importance. The use of fractal analysis method is being investigated in order to differentiate periodontal disease radiographically. Fractal analysis presents the degree of complexity in the structure of fractal objects as a numerical data, and has been used to measure changes in trabecular bone. The aim of this study was to compare the trabecular bone fractal dimension (FD) values of patients with periodontitis and gingivitis using panoramic radiographs, and to evaluate the possible relationship between age and gender with fractal dimension.
Panoramic radiographs of 64 patients with gingivitis and 64 patients with periodontitis were evaluated retrospectively in the study. Using the radiographs of the patients, FD values measured from the trabecular bone were calculated with the box-counting method in the Image J programme. The FD values of both groups were compared. In addition, the relationship between age and gender parameters and FD values was evaluated within the groups.
According to the results of the study, the calculated average FD value of the patients in the gingivitis group was 1.195, while the calculated average FD value of the patients in the periodontitis group was 1.196. No statistically significant difference was observed between the FD values of the gingivitis group and the periodontitis group (p > 0.05). No statistically significant correlation was observed between FD values and age and gender (p > 0.05).
No statistically significant results were obtained for the calculated mean FD values of the patients in the gingivitis and periodontitis groups.
早期诊断和治疗牙周炎（可导致牙齿骨质丧失）非常重要。目前正在研究使用分形分析方法来对牙周病进行放射学诊断。分形分析将分形物体结构的复杂程度表示为数值数据，并已用于测量小梁骨的变化。本研究旨在通过全景片比较牙周炎和牙龈炎患者的小梁骨分形维数（FD）值，并评估年龄和性别与分形维数的可能关系。
本研究回顾性评估了 64 例牙龈炎患者和 64 例牙周炎患者的全景片。使用患者的 X 光片，通过 Image J 程序中的盒子计数法计算出小梁骨的 FD 值。比较两组的 FD 值。此外，还评估了组内年龄和性别参数与 FD 值之间的关系。
根据研究结果，牙龈炎组患者的平均 FD 值为 1.195，牙周炎组患者的平均 FD 值为 1.196。牙龈炎组和牙周炎组的 FD 值无统计学差异（p>0.05）。FD 值与年龄和性别无统计学相关性（p>0.05）。
牙龈炎和牙周炎组患者的平均 FD 值无统计学差异。
