简要总结
This study aim to evaluate the effects of a 6-week self-management program on pain, muscle stiffness, and temporomandibular joint (TMJ) functions in sedentary individuals aged 18-40 with bruxism. Thirty-five individuals will be evaluated. Bruxism will be assessed using the Bruxism Assessment Questionnaire, while temporomandibular joint dysfunction (TMJD) will be evaluated using the Helkimo Clinical Dysfunction Index and the Fonseca Questionnaire. Masseter muscle pain threshold will be measured with a digital algometer, muscle stiffness with a Shore Durometer, mandibular depression range of motion with a bicondylar caliper, and TMJ proprioception with TMJ position sense. Assessments will be conducted pre-intervention and at the end of the fourth week.
详细描述
The 4-week self-management program significantly increased the masseter pain threshold (p<0.001) and reduced muscle stiffness at rest and during contraction (p<0.001). TMJD severity, as measured by the Helkimo Index (p=0.010) and Fonseca Questionnaire (p<0.001), was significantly reduced. Additionally, TMJ position sense and mandibular depression range of motion improved significantly (p<0.001). Self-management strategies positively impact bruxism symptoms, including pain, muscle stiffness, and TMJ functions. These strategies should be considered an integral part of TMJD and bruxism management.

结局指标
主要结局
Temporomandibular Joint Dysfunction
时间窗: 8 weeks
Temporomandibular Joint Disorder (TMJD) will be evaluated using the Helkimo Clinical Dysfunction Index (HCDI). This instrument is considered valid and reliable measures of TMJD. The scoring system categorises participants into four groups: no clinical symptoms (score 0), mild TMJD (scores 1-4), moderate TMJD (scores 5-9), and severe TMJD (scores 10-25)
Bruxism Assessment
时间窗: 8 weeks
Bruxism will be assessed using self-reports, which are considered appropriate for both clinical and research purposes. Awake bruxism will be diagnosed based on participants' self-awareness, determined by asking whether they had noticed clenching or grinding their teeth while awake in the past six months. Individuals who respond affirmatively will be classified as having awake bruxism. Sleep bruxism will be diagnosed using the 2014 criteria established by the American Academy of Sleep Medicine (AASM). Participants will be asked whether they frequently noticed teeth grinding during sleep, will be informed of it by others, or observed excessive tooth wear. Additionally, they will be questioned about symptoms upon waking, such as jaw fatigue, tension, or pain; sensations of clenching or pain in the mouth; temple pain; difficulty opening the mouth; tension in the jaw joint requiring movement to release; or clicking sounds in the jaw joint that disappear afterward.
Masseter Muscle Pain Threshold Measurement
时间窗: 8 weeks
The pain threshold of the masseter muscle will be assessed bilaterally over the muscle belly using a JTECH Commander digital algometer. Three measurements will be taken from the muscle belly, and the average value will be calculated. Participants will be instructed to indicate the moment they first perceived pain, and the value will be display on the device will be recorded as the pain threshold in pounds. Higher scores indicate better pain threshold.
Masseter Muscle Stiffness
时间窗: 8 weeks
The stiffness of the masseter muscle will be assessed using a Shore Durometer OO (M\&A Instruments Inc., United States), a handheld device designed for convenient and non-invasive measurement of muscle stiffness. The durometer evaluates tissue properties by measuring oscillations generated through mechanical contact with the assessed muscle. Measurements will be performed bilaterally over the belly of the masseter muscle during both resting and maximum contraction states. Each measurement will be repeated three times, and the average values will be recorded in Newtons per meter.
次要结局
- Temporomandibular Joint Position Sense(8 weeks)
- Mandibular Depression Range of Motion(8 weeks)
