The temporomandibular joint is the joint that connects jaw to skull. When this joint is injured or damaged, it can lead to a localized pain disorder called temporomandibular joint (TMJ) syndrome or temporomandibular disorder (TMD), also said as TMJ Arthritis as it related to inflammation of joint. The prognosis of this case is good. Some patient able to get this disorder resolve by some treatment and home remedies. Only a few of them need to get the surgery.
3. INTRODUCTION
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.

4. TMJ Facts!
The only mobile joint of skull
formed between head of mandible
and articular fossa of temporal
bone.

The only joint in human body that have
a rigid endpoint of closure.
Stress can make
TMJ disorder
worse.
5. The temporomandibular joint is the
joint that connects your jaw to your
skull. When this joint is injured or
damaged, it can lead to a localized pain
disorder called temporomandibular
joint (TMJ) syndrome or
temporomandibular disorder (TMD).

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
9. Symptoms:
▪ Pain or tenderness of your jaw
▪ Pain in one or both of the temporomandibular joints
▪ Aching pain in and around your ear
▪ Difficulty chewing or pain while chewing
▪ Aching facial pain
▪ Locking of the joint, making it difficult to open or close your
mouth
▪ Headaches, backaches, ear ringing (tinnitus)

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.
