jaw joint pain

Introduction

Introduction Chin joint pain is one of the clinical manifestations of temporomandibular joint dysfunction syndrome, and is a common disease in the oral and maxillofacial region.

Cause

Cause

1. Trauma factors Many patients have a history of local trauma. Such as the impact of external forces, sudden biting hard objects, excessive mouth opening (such as yawning) and other acute trauma; there are often chew hard food, night molars and unilateral chewing habits. These factors may cause joint contusion or strain, and the dysfunction of the masticatory muscle group may also have an effect on the occurrence of this disease.

2. Occlusal factors Many patients have obvious occlusal disorders. Such as excessive cusp, excessive tooth wear, excessive tooth loss, poor dentures, and low distance between jaws. The disorder of the occlusal relationship can destroy the balance of functions between the internal structures of the joints and promote the occurrence of this disease.

3. Systemic and other factors Neuropsychiatric factors may have a relationship with this disease. For example, some patients have emotional irritability, nervousness, and excitement. In addition, some patients have a history of rheumatism, and some are related to cold.

Clinical manifestation

The main clinical manifestations of temporomandibular joint disorder syndrome are local soreness or pain, squeaking and movement disorders. The pain can be in the joint area or around the joint; it can be accompanied by tenderness of varying degrees of weight. Swelling or pain in the joints is especially noticeable when chewing and opening. The popping occurs when the mouth is open. The sound can occur at different stages of the jaw movement, and can be a crisp single or broken sound. Common movement obstruction is limited by mouth opening, but it can also occur when the mouth is too large or the mouth is bent. In addition, it can be accompanied by symptoms such as ankle pain, dizziness, and tinnitus.

diagnosis

According to the medical history, it is not difficult to diagnose the temporomandibular joint disorder syndrome with the above main symptoms. Common methods for assisted diagnosis are:

1X line plain film (synaptic Xue's position and sacral process through the pharyngeal side), can be found in joint space changes and bone changes, such as sclerosis, bone destruction and hyperplasia, cystic changes.

2 joint angiography (upper cavity angiography is easy to use and easy to use, lower luminal angiography is less domestic application), can find joint disc displacement, perforation, joint disc attachment changes and cartilage surface changes. In recent years, many scholars have used arthroscopy to detect early changes in the disease, such as articular disc and synovial congestion, oozing, adhesion, and "articular rat" formed by undifferentiated mature cartilage-like tissue. Because there are many types of this disease, the treatment methods vary. Therefore, a specific type of diagnosis should be made. Such as pterygoid tendon, reversible disc displacement or joint disc wear.

Diagnosis

Differential diagnosis

Differential diagnosis of chin joint pain:

Temporomandibular arthritis

1 acute suppurative arthritis of temporomandibulor joint, the joint area can be seen red and swollen, tenderness is obvious, especially can not up and down, a little exertion can cause severe pain in the joint area.

Two types of rheumatoid arthritis of temporomandibular joints, often accompanied by systemic migratory, multiple arthritis, especially the lower extremities of the limbs are most often involved, joint stiffness can occur in the late stage.
