Orthodontic treatment involves manipulation of tooth position that can temporarily lead to occlusal interferences capable of inducing bruxism. The objectives of this study were to determine the self-reported incidence of bruxism and its association with factors such as facial type, divergence, skeletal and dental malocclusions in orthodontic patients.
80 patients who underwent a minimum of six months of orthodontic treatment were surveyed using a validated self-reported bruxism questionnaire for the presence or absence of bruxism. Data regarding patients' facial type, divergence, skeletal and dental malocclusions were measured and collected from the patients' orthodontic records. Binomial logistic regression analysis was used to assess the association of these factors with bruxism.
About 45% of the orthodontic patients reported bruxism after the commencement of orthodontic treatment. The median age of the sample was 19.8 (17.7, 24.3) years and 60% of them were women. Binomial logistic regression analysis showed an insignificant association of gender and age with bruxism. When analyzing the association with facial type, divergence, skeletal and dental malocclusion no statistically significant association was found. However, patients with hypodivergent face [odds ratio (OR) = 2.4; 95% confidence interval (CI) = 0.7-8.5] and dental class III [OR = 4.0; 95% CI = 0.3-51.0] were more likely to report bruxism after the initiation of orthodontic treatment. A statistically significant association was found with jaw fatigue or soreness upon awakening (28.7%), clenching (27.5%) and grinding (25%) in the bruxism group (p-value ≤ 0.001). Teeth and gum soreness were also significantly associated with bruxism, affecting 25% of the orthodontic patients (p-value ≤ 0.001). On the contrary, nocturnal grinding (10%) and temporal headaches (21.3%) were negatively correlated with bruxism.
There is a risk of bruxism among orthodontic patients, with 45% of them reporting bruxism following the initiation of treatment. Patients with bruxism commonly reported jaw fatigue or soreness upon awakening, clenching, grinding, teeth and gum soreness. Factors such as facial type, facial divergence, skeletal and dental malocclusions have no impact on the onset of bruxism during orthodontic treatment.
正畸治疗涉及牙齿位置的调整，这可能会暂时导致咬合干扰，进而引发磨牙症。本研究的目的是确定正畸患者自我报告的磨牙症发病率及其与面部类型、面部差异、骨骼和牙齿错颌等因素的关联。
使用经过验证的自我报告磨牙症问卷，对80名接受了至少六个月正畸治疗的患者进行调查，以确定是否存在磨牙症。从患者的正畸记录中测量并收集有关患者面部类型、面部差异、骨骼和牙齿错颌的数据。采用二项逻辑回归分析来评估这些因素与磨牙症的关联。
约45%的正畸患者在正畸治疗开始后报告有磨牙症。样本的中位年龄为19.8（17.7，24.3）岁，其中60%为女性。二项逻辑回归分析显示，性别和年龄与磨牙症的关联不显著。在分析与面部类型、面部差异、骨骼和牙齿错颌的关联时，未发现统计学上的显著关联。然而，面部低角型患者[比值比（OR）=2.4；95%置信区间（CI）=0.7 - 8.5]和安氏III类错颌患者[OR = 4.0；95% CI = 0.3 - 51.0]在正畸治疗开始后更有可能报告有磨牙症。在磨牙症组中，发现与醒来时颌部疲劳或酸痛（28.7%）、紧咬（27.5%）和磨牙（25%）有统计学上的显著关联（p值≤0.001）。牙齿和牙龈酸痛也与磨牙症显著相关，影响了25%的正畸患者（p值≤0.001）。相反，夜间磨牙（10%）和颞部头痛（21.3%）与磨牙症呈负相关。
正畸患者存在磨牙症风险，45%的患者在治疗开始后报告有磨牙症。有磨牙症的患者通常报告醒来时颌部疲劳或酸痛、紧咬、磨牙、牙齿和牙龈酸痛。面部类型、面部差异、骨骼和牙齿错颌等因素在正畸治疗期间对磨牙症的发生没有影响。
