TMJ arthritis is the inflammation of the temporomandibular joint, which connects the jaw to the skull, and can cause localized pain and discomfort. Symptoms include jaw pain, difficulty chewing, and headaches, while investigations may include imaging techniques like MRI and ultrasound. Management options range from conservative treatments like physical therapy and medications to surgical interventions if necessary.

What is TMJ Arthritis
TMJ Arthritis is refer to inflammation of
Temporomandibular joint.
The TMJ is a ginglymoarthrodial joint, a term
that is derived from ginglymus, meaning a hinge
joint, allowing motion only backward and
forward in one plane, and arthrodia, meaning
a joint of which permits a gliding motion of the
surfaces.

TMJ FUNCTION

8. The temporomandibular joint combines a hinge
action with sliding motions. The parts of the bones
that interact in the joint are covered with cartilage
and are separated by a small shock-absorbing disk,
which normally keeps the movement smooth.
Cause
Painful TMJ disorders can occur if:
The disk erodes or moves out of its
proper alignment due to dental procedure
or craniofacial structure at birth due to
genetic
The joint's cartilage is damaged by
arthritis eg osteoarthritis
The joint is damaged by a blow or other
impact/trauma
Excessive gum chewing, nail biting,
bruxism (habitual teeth grinding)
Stress
Poor posture
In many cases, however, the cause of TMJ
disorders isn't clear.8

15. Risk factors
Factors that may increase the risk of developing TMJ disorders include:
1
Various types of arthritis, such
as rheumatoid arthritis and
osteoarthritis
2 Jaw injury
3
Long-term (chronic) grinding or
clenching of teeth
4
Certain connective tissue diseases
that cause problems that may affect
the TMJ

16. Prevention

✋Avoiding oral habits since child such as:
👆Manage stress
👉Avoiding chewing gum
👍Try softer foods to give your jaw a break from crunching and grinding your food
💃Practice good posture
🏃💑❤😸💣📌📖🔨🎈🎨🏈🏰🌏🔑👧👨👩
🎈non-nutritive sucking 🎈using pacifier
🎈mouth breathing 🎈tongue thrusting

17. Some of these effects may not be
noticeable until adulthood when most
TMJ disorder symptoms arise, although
some people have symptoms in the
teenage years. Women age 18-44 years
old tend to be more risky to get TMD.
