Abstract

Objectives: This study examined changes in magnetic resonance imaging (MRI) of temporomandibular joints (TMJ) with anterior displacement disk without reduction (DDwoR) and its correlation to clinical symptoms.

Methods: 190 individuals with DDwoR were evaluated according to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and MRI. Pain's chronicity/intensity and limited mouth opening (locking) were correlated with: TMJ degeneration (MRI T1), effusion (T2), disc's shape and position (proton density).

Results: In 103 TMJ with DDwoR, hemiconvex shape (41.6%), sclerosis (45.6%) and mild effusion (47.6%) were the most prevalent findings. There was not association (p > .05) between: different DDwoR positions with pain's intensity/chronicity; effusion with locking. Disk deformation was associated with degeneration (p = .034) and pain's intensity (p = .006). Locking was associated with degeneration (p = .05).

Conclusions: Condylar osteodegeneration is often related to DDwoR. Locking by DDwoR is associated with severe levels of chronic pain and articular disk deformation.

颞下颌关节伴关节盘移位无复位的MRI变化和临床特征——一项横断面观察研究。

目的：探讨颞下颌关节（TMJ）前盘无复位移位（DDwoR）的磁共振成像（MRI）变化及其与临床症状的相关性。方法：根据《颞下颌疾病诊断标准》（DC/TMD）和MRI对190例DDwoR患者进行评估。疼痛的慢性/强度和张嘴受限（闭锁）与：TMJ退变（MRI T1）、积液（T2）、椎间盘形状和位置（质子密度）相关。结果：103例DDwoR患者中，以半凸型（41.6%）、硬化症（45.6%）和轻度积液（47.6%）最为常见。不同DDwoR位置与疼痛强度/慢性程度无显著相关性（p < 0.05）；积液带锁。椎间盘变形与退变（p = 0.034）和疼痛强度（p = 0.006）相关。锁定与退变相关（p = 0.05）。结论：髁突骨变性常与DDwoR有关。DDwoR导致的锁定与严重的慢性疼痛和关节盘变形有关。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
