Temporomandibular joint ankylosis

Joint ankylosis is the fixation and loss of movement of a joint due to disease, injury, or surgery. Temporomandibular joint ankylosis can be clinically classified into intra-articular ankylosis and extra-articular ankylosis. It often presents as chronic, painless limitation of mouth opening. Extra-articular ankylosis involves lesions in the skin, mucous membranes, or deep tissues between the upper and lower jaws outside the joint, also known as intermaxillary contracture, or sometimes referred to as pseudoankylosis. This condition can be divided into fibrous intermaxillary contracture and bony intermaxillary contracture based on the nature of the lesion. Intra-articular ankylosis is caused by lesions occurring within one or both joints, ultimately leading to fibrous or bony adhesions within the joint. This is simply called joint ankylosis, or sometimes true ankylosis. According to pathological changes, it can be divided into fibrous ankylosis and bony ankylosis. Furthermore, when both intra-articular and extra-articular ankylosis are present simultaneously, it is called mixed ankylosis.

Temporomandibular ankylosis

Temporomandibular joint contracture refers to a condition where the temporomandibular joint is damaged, leading to scar formation and shortening of the surrounding ligaments and joint capsule. This prevents the joint from fully extending, resulting in limited mouth opening. The main symptom is varying degrees of limited mouth opening, or complete difficulty in opening the mouth.

Acute apical periodontitis

Acute apical periodontitis refers to the acute inflammation of the tooth root and its surrounding tissues (cementum, periodontal ligament, and alveolar bone). It often develops from acute pulpitis or is an acute exacerbation of chronic apical periodontitis. Clinically, it can be divided into two types: acute serous apical periodontitis and acute suppurative apical periodontitis. The main symptoms of this disease are pain and pain on biting.

Black hairy tongue

Black hairy tongue is a condition characterized by hypertrophy and hyperkeratosis of the filiform papillae, along with increased local pigmentation due to the action of pigment-producing bacteria or fungi, resulting in a black or brownish-gray appearance of the tongue surface. It is more common in middle-aged individuals, with a higher incidence in males than females, and is rare in children. The main symptom is black "hairs" on the dorsum of the tongue, with the color becoming darker towards the midline.

Alveolar osteitis

Alveolar osteitis is a localized oral infection that occurs after tooth extraction (especially after the extraction of complex mandibular molars). It is a bone wound infection caused by oral bacteria, most commonly occurring after the extraction of mandibular third molars, with an incidence rate between 5% and 30%. The main symptoms are severe pain in the alveolar socket 2 to 3 days after tooth extraction, radiating outwards, accompanied by a foul odor.

Radicular cyst

A radicular cyst, also known as a periapical cyst, is an odontogenic jaw cyst that is a chronic lesion of chronic periapical periodontitis, developing from a periapical granuloma or chronic alveolar abscess. In its early stages, this disease has no obvious symptoms. In later stages, it may present with tooth discoloration, recurrent gum abscesses, and gum swelling.
