摘要

目的:应用分形维数分析(分形维数分析)探讨根管治疗与未根管治疗牙齿正畸运动时根周组织的变化是否存在差异。方法:采用固定正畸治疗前(T1)和后(T2)的全景x线片进行回顾性档案研究。将32颗下颌第一、第二磨牙的全景x线片分为两组:第一组(n:17),对照组为未进行根管治疗的下颌第一、第二磨牙x线片;第二组(n:15)为进行根管治疗的下颌第一、第二磨牙x线片。分形分析进行了四个不同的区域-尖周,分岔,尖周内侧和尖周远端区域的下颌磨牙包括在研究共128个分析。结果:对照组正畸治疗对牙齿四个区域分形维数的影响无统计学意义(p >0.05)。在根管治疗组中,正畸治疗后中尖周区域分形维数值升高有统计学意义(p <0.05)。结论:本研究FA值显示根管治疗组和根尖周内侧区域发生了更多的生物相互作用。因此,将正畸力控制在牙齿的生理极限内是非常重要的,以避免在正畸治疗过程中应力积累的尖周区域损伤牙齿。k kkaraca E, Sarıçam E.用分形维数分析评价ⅱ类固定正畸治疗对根管治疗后下颌磨牙根周骨结构的影响。国际医学杂志,2013;13(S1):38-43。https://doi.org/10.5577/idr.2023.vol13.s1.6语言修改:本手稿中的英语已由至少两名专业编辑检查,他们都是英语母语者。

Evaluation of the effect of class II fixed orthodontic treatment on the periradicular bone structure of endodontically treated mandibular molar teeth using fractal dimension analysis
Aim: The aim of this study was to investigate whether changes in periradicular tissues with orthodontic movement of root canal-treated teeth differ from those without root canal treatment using fractal dimension analysis (FA). Methodology: A retrospective archive study was performed using panoramic radiographs taken before (T1) and after (T2) fixed orthodontic treatment. Panoramic radiographs of a total of 32 mandibular 1st and 2nd molar teeth were divided into groups: Group 1 (n:17), the control group, comprised radiographs of mandibular 1st or 2nd teeth without root canal treatment, and Group 2 (n:15) comprised radiographs of 1st or 2nd mandibular molars with root canal treatment. Fractal analyses were performed in four different regions—the periapical, bifurcation, mesial periapical, and distal periapical regions—of the mandibular molar teeth included in the study for a total of 128 analyses. Results: In the control group, orthodontic treatment did not make a statistically significant difference to the fractal dimension values in the four regions of the tooth (p > 0.05). In the endodontically treated group, the fractal dimension values of the mesial periapical regions increased statistically significantly after orthodontic treatment (p < 0.05). Conclusion: The FA values of this study showed that more biological interaction occurred in the root canal treatment group and in the mesial periapical region. Thus, it is important to keep orthodontic force within the tooth’s physiological limits to avoid damaging the tooth in the periapical areas where stress accumulates during orthodontic treatment.
