Temporomandibular Disorders Quiz

The upper joint compartment formed by the articular disc and the temporal bone, responsible for the secondary gliding motion of the jaw during wide opening.

The part of the mandible that connects to the undersurface of the articular disc.

The part of the temporal bone that joins the upper surface of the articular disc.

Factors that increase the risk of developing temporomandibular disorders.

Factors that directly lead to the onset of temporomandibular disorders.

Factors that hinder healing or worsen existing TMJ disorders.

The relationship between the upper and lower teeth when the jaws are closed.

Behavioral patterns like grinding, clenching and abnormal head posture that can contribute to perpetuating TMJ disorders.

Negative thoughts and attitudes that can make it harder to recover from a condition.

Conditions that increase the risk of developing Temporomandibular Disorders (TMD). These can be physical, psychological or structural issues.

A bite where the upper front teeth are far forward and don't touch the lower front teeth.

When the jaw shifts more than 4mm when moving from a relaxed position to a biting position.

Injuries caused by dental procedures that can lead to TMD.

Systemic diseases that can affect the jaw joint and potentially lead to TMD.

Symptoms that may indicate a problem with the temporomandibular joint.

A situation where the jaw locks and it's hard to open or close the mouth. It can be caused by stress, misalignment, or teeth grinding.

Limited opening of the jaw (reduced range of motion) due to muscle spasm, often caused by clenching or other factors. Can temporarily interfere with eating, speaking, and oral hygiene.

Pain originating from the temporomandibular joint, often accompanied by jaw clicking or popping.

Pain originating from the muscles surrounding the temporomandibular joint.

A grinding or creaking sound in the TMJ, often indicating arthritis or other degenerative processes.

A clicking or popping sound in the TMJ, usually associated with the displacement of the disc.

Pain that can cause difficulty opening the mouth and is often accompanied by headaches or soreness in the neck and face.

A condition where the jaw muscles are constantly clenched or tightened, often happening during sleep (bruxism) and contributing to TMJ disorders.

A condition that specifically affects the muscles of mastication (chewing) and can cause pain, limited jaw movement, and clicking in the jaw.

A condition where the articular disk is displaced anterior to the condyle, resulting in limited jaw opening (locked jaw) and pain in the ear and around the TMJ.

A clicking, snapping or popping sound that occurs when the articular disk moves onto or off the condylar head during jaw opening.

The most common form of internal TMJ derangement where the articular disk is displaced forward.

A condition where the articular disk remains anterior to the condyle, even with jaw opening, resulting in restricted jaw movement and pain.

A condition where the articular disk returns to its correct position on the condylar head during jaw opening, leading to limited pain and clicking.

Abnormal jaw movement due to congenital or acquired problems like trauma or arthritis.

Painful condition causing difficulty in opening mouth, usually accompanied by headaches or soreness in neck and face.

Occurs when the disk displaced anterior, causing limited opening and pain in the joint.

A temporary condition where the jaw pops without associated pain, often caused by habits like teeth grinding or clenching.

A disorder affecting the temporomandibular joint (TMJ) causing discomfort, limited movement, and sometimes clicking or popping sounds.

A medical condition where joint cartilage weakens, causing pain and restricted movement. It's often associated with popping or clicking in the TMJ.

A temporary locking of the jaw, often caused by the articular disc in the TMJ shifting out of place. It's typically painful, and opening the mouth is difficult.

A specific symptom of TMD, characterized by limited jaw opening due to muscle spasms, joint stiffness, or structural issues like ankylosis (fusion of the joint).

A process used to objectively measure and document the range of jaw movement in different directions, helping diagnose and assess TMD.

A comparison of jaw opening capabilities between individuals with TMD and healthy individuals, often revealing significant differences in jaw opening amplitude.

Patients with TMD may be categorized into subgroups based on the underlying cause of pain, like muscle pain (myogenous) or joint pain due to disc displacement (arthrogenous).

Excessive anterior movement of the jaw and articular disc, often causing clicking sounds and deviation of the jaw away from the affected side. Can be linked to connective tissue disorders like Marfan syndrome.

A condition where the articular disc fails to reduce back into place on closing the mouth, leading to a locked jaw that's stuck open. Often occurs after extreme jaw movements or dental procedures.

The most widely used diagnostic criteria for Temporomandibular Disorders (TMD), relying on patient history and physical examination findings.

Pain that lasts for more than three months, signifying a chronic condition.

Physical exam signs suggesting TMD, including abnormal jaw movement, limited range of motion, pain in jaw muscles, and tenderness in the neck or shoulders.

A clicking sound during jaw opening might indicate an anterior disk displacement. A second click during closure signifies the disk moving back into place, indicating a disk displacement with reduction.

A condition involving the TMJ that affects how the joint moves, often accompanied by clicking, popping, grating, or locking.
