Brief Summary

The goal of this study is to evaluate the short- and long-term effects of a self-administered exercise program on pain levels, jaw movement range, and jaw function in patients with temporomandibular joint (TMJ) disorders. The main question it aims to answer is: Does adding a self-administered exercise program to arthrocentesis improve pain, mouth opening, and jaw function compared to arthrocentesis alone in patients with TMJ disorders? Participants with acute or chronic TMJ pain lasting at least three months and limited mouth opening will undergo arthrocentesis, with one group also following an exercise regimen. Outcomes will be assessed over a 6-month follow-up period.

Outcome Measures

Primary Outcomes (2)

• Maximum Amount of Mouth Opening

  For mouth opening measurement, the distance between the incisal edges of the lower and upper first incisors will be measured using a digital caliper and will be recorded in millimeters at the end of each examination. In patients with missing teeth, the teeth on the left side will be used for the measurement. In order to determine the amount of movement of the lower jaw in the lateral direction, patients will be asked to shift their lower jaws to the right and left. The amount of displacement of the midline of the lower jaw teeth relative to the midline of the upper jaw teeth will be measured with a digital caliper. The distances obtained will be recorded in millimeters at the end of each examination.

  Measurements will be conducted at five time points, from enrollment through the 6-month follow-up period: (1) pre-arthrocentesis, (2) postoperative 1st week, (3) postoperative 1st month, (4) postoperative 3rd month, and (5) postoperative 6th month.

• Pain Intensity

  A visual analog scale (VAS) will be used to measure pain intensity. The scale consists of a 10-centimeter straight line, with '0' at the starting point indicating no pain and '10' at the endpoint representing the highest pain level tolerable. During each examination session, individuals will mark the point on the line that corresponds to their pain intensity. The distance from the '0' point to the marked position will be measured in centimeters, with greater distances indicating higher pain intensity.

  Measurements will be conducted at five time points, from enrollment through the 6-month follow-up period: (1) pre-arthrocentesis, (2) postoperative 1st week, (3) postoperative 1st month, (4) postoperative 3rd month, and (5) postoperative 6th month.

Secondary Outcomes (1)

• Jaw Function Limitation

  Measurements will be conducted at five time points, from enrollment through the 6-month follow-up period: (1) pre-arthrocentesis, (2) postoperative 1st week, (3) postoperative 1st month, (4) postoperative 3rd month, and (5) postoperative 6th month.

Study Arms (2)

Arthrocentesis Group

Patients with arthralgia and limited mouth opening at least 3 moths, if volunteered, will be enrolled to this group. The patients will undertake a TMJ arthrocentesis, will be recommended behavioural modifications and diet alterations.

Procedure: Temporomandibular Joint Arthrocentesis

Self-Exercise Following TMJ Arthrocentesis

Patients with arthralgia and limited mouth opening at least 3 moths will be enrolled to this group. The patients, if volunteered, will undertake a TMJ arthrocentesis, will be recommended behavioural modifications and diet alterations. Following the arthrocentesis procedure, the patients will be instructed an exercise regimen adopted from the current literature, and asked to perform the regimen for postoperative six weeks.

Procedure: Self Exercise Following Arthrocentesis

Interventions

Temporomandibular Joint Arthrocentesis PROCEDURE

The symptomatic temporomandibular joint (TMJ), either right or left, will be anesthetized using an auriculotemporal nerve block and intracapsular anesthesia. The arthrocentesis procedure will be performed using the double-puncture technique. A 21-gauge needle will be inserted into the posterior region of the joint capsule, targeting the upper joint compartment at a point located 10 mm anterior to the tragus. A second 21-gauge needle will be introduced into the anterior region of the joint capsule, also targeting the upper compartment, at a point located 20 mm anterior to the tragus. The upper joint compartment will then be irrigated with a minimum of 200 mL of saline solution through one of the needles.

Arthrocentesis Group

Self Exercise Following Arthrocentesis PROCEDURE

Following the arthrocentesis procedure described for the other study group, patients will undergo a standardized exercise regimen based on established literature. The regimen includes two sets of movements. The first set involves freely opening the jaw, shifting it right, left, and forward, and repeating these movements while applying finger resistance-closing the mouth against the pressure or forcing the jaw open with the fingers. Each movement will last 10 seconds and be performed 10 times daily. The second set aims to improve the mandibular condyle-articular disc relationship. Patients will open their mouth as wide as possible, advance their lower jaw fully, and close their teeth in an edge-to-edge position. These movements will be performed three times daily for 5 minutes after meals.
