简要总结
The study aims to compere mandibular splint versus botox injection in lateral pterygoid on cervical muscle activity in patients with temporomandibular disorders
详细描述
Temporomandibular disorders (TMD) are common chronic musculoskeletal pain conditions among orofacial pain, consisting of a group of conditions associated with pain and dysfunction of the temporomandibular joint (TMJ) and masticatory muscles. Temporomandibular joint displacement, also known as internal disc derangement, is an abnormal relationship between the articular disc, the mandibular condyle, and the mandibular fossa. The most frequent displacement of the disc is anterior to the mandibular condyle however, in rare cases it can be posteriorly.
Occlusal splint treatment is generally considered to be a basic treatment for Temporomandibular disorders. It could promote correction of the vertical dimension, maxillo-mandibular realignment, temporomandibular joint repositioning and cognitive awareness. Although various splints are currently available, the most used are stabilization splints and anterior repositioning splints.
Injection of BTX-A in LP muscle, considering the different methods, frequencies and injection dosages used in different studies, would decrease the clicks and other TMJ-related disorders such as pain, hyperactivity, and dysfunction. Based on the present review, most studies about the injection of botulinum toxin in LP muscle reported cases or were done as quasi-experimental studies.

研究组 & 干预措施
Botox injection group
Patients will be treated by Botox injection in lateral pterygoid muscle and medications like muscle relaxants, antidepressants, and nonsteroidal anti-inflammatory drugs.
A Botox-A vial was diluted with normal saline to a concentration of 10 U per 0.1 mL for injection in a 1-ml insulin syringe. This will be injected into the ipsilateral lateral pterygoid muscle
干预措施: Botox injection (Drug)
Mandibular stabilization splint group
Patients will be treated by mandibular stabilization splint and medications like muscle relaxants, antidepressants and nonsteroidal anti-inflammatory drugs.
干预措施: Mandibular stabilization splint (Drug)
Control group
Patients will be treated by medications like muscle relaxants, antidepressants and nonsteroidal anti-inflammatory drugs.
干预措施: Muscle relaxant (Drug)
结局指标
主要结局

时间窗: After injection for 3 months.
Muscle activity of upper trapizieus and sternocleidomastoid will be recorded before and after injection for 3 months by neurosoft Electromyography
次要结局
- Amplitude of muscle activity(After injection for 3 months.)
- Root mean square of muscle activity(After injection for 3 months.)
