Bruxism is defined as a movement disorder of the masticatory system leading to serious problem in the integrity of the oral dentition; it is characterized by teeth grinding and clenching and has been typically classified into three types: a) bruxism occurring during sleep, b) awake-related bruxism, and c) mixed sleep/awake-related bruxism.
The aim of this study was to assess any bone apposition in the mandibular angle in a group of adult patients diagnosed with bruxism using digital panoramic radiographs.
In the sample of 150 digital panoramic radiographs of 66 women and 84 men with an age range of 24-78 years and diagnosed with bruxism were evaluated.
Among the 300 mandibular angles evaluated, 156 (52%) showed bone apposition against 144 (48%) who did not.
The changes in the mandibular angle, especially bone apposition, can help diagnosing long term bruxism on panoramic radiographs.
磨牙症被定义为咀嚼系统的一种运动障碍，会导致口腔牙列完整性出现严重问题；其特征为磨牙和紧咬牙，通常分为三种类型：a）睡眠期间发生的磨牙症，b）与清醒相关的磨牙症，以及c）睡眠/清醒混合相关的磨牙症。
本研究的目的是使用数字化全景X线片评估一组被诊断为磨牙症的成年患者下颌角的骨增生情况。
对年龄在24至78岁之间、被诊断为磨牙症的66名女性和84名男性的150张数字化全景X线片样本进行了评估。
在评估的300个下颌角中，156个（52%）显示有骨增生，144个（48%）未显示。
下颌角的变化，尤其是骨增生，有助于在全景X线片上诊断长期磨牙症。
