The 5 most common pathological conditions, lesions, cysts, or tumors of the temporomandibular joint (TMJ) in order from least common to most common are as follows:

1. Synovial Chondromatosis: A rare condition characterized by the formation of cartilaginous nodules in the synovium of the TMJ. These nodules can calcify and become loose bodies within the joint space.

2. Osteochondroma: This benign bone tumor can arise in the TMJ and is relatively uncommon. It may lead to joint dysfunction, facial asymmetry, or limited mandibular movement.

3. Osteoarthritis: A degenerative joint disease that affects the TMJ, leading to the breakdown of cartilage and resulting in pain, stiffness, and crepitus. It is more common in older individuals.

4. Temporomandibular Joint Disorder (TMD): A broad term encompassing a variety of conditions affecting the TMJ, muscles of mastication, and associated structures. Symptoms may include pain, restricted movement, and clicking or popping sounds. TMD is one of the most common TMJ-related conditions.

5. Internal Derangement: The most common pathological condition affecting the TMJ, characterized by an abnormal relationship between the articular disc and the mandibular condyle. It often presents with pain, clicking, or locking of the jaw.

These conditions vary in their frequency and impact, with internal derangement and TMD being the most commonly encountered in clinical practice.
