OBJECTIVES
This study aimed to establish a difference in mandibular bone density between bruxer and non-bruxer patients, based on panoramic radiographs.
METHODS
Panoramic radiographs of bruxer and non-bruxer patients were analyzed with ImageJ. Several radiological determinants were studied on the patients' panoramic radiographs: gray values of cancellous bone and cortical bone, and bony exostoses at the mandibular angle.
RESULTS
Thirty-seven bruxers and forty-seven non-bruxers were included in the study. A statistically significant difference (p < 0.05) was noted in the cancellous to cortical bone ratios of bruxers and non-bruxers: the density of cancellous bone was greater in bruxers than in non-bruxers. The number of bony exostoses at the mandibular angle was significantly higher in bruxers (p < 0.05).
CONCLUSIONS
This study obtained radiological determinants of bruxism from panoramic radiographs. Further studies are needed to supplement this preliminary approach, especially via the analysis of three-dimensional imaging to overcome the limitations of panoramic radiography.
目的
本研究旨在基于全景X线片确定磨牙症患者与非磨牙症患者下颌骨密度的差异。
方法
使用ImageJ分析磨牙症患者和非磨牙症患者的全景X线片。在患者的全景X线片上研究了几个放射学决定因素：松质骨和皮质骨的灰度值以及下颌角的骨外生骨疣。
结果
本研究纳入了37名磨牙症患者和47名非磨牙症患者。磨牙症患者和非磨牙症患者的松质骨与皮质骨比率存在统计学显著差异（p < 0.05）：磨牙症患者的松质骨密度高于非磨牙症患者。磨牙症患者下颌角的骨外生骨疣数量显著更高（p < 0.05）。
结论
本研究从全景X线片中获得了磨牙症的放射学决定因素。需要进一步的研究来补充这种初步方法，特别是通过三维成像分析来克服全景X线摄影的局限性。
