Gingivitis
Gingivitis is a non-specific inflammation of the gingival soft tissue caused by dental plaque on the tooth surface, and it is one of the most common gingival diseases. Common manifestations of this disease include bright red, swollen gums, and bleeding gums when brushing teeth or biting hard objects.
View detailsCysts of the oral and maxillofacial region
Oral and maxillofacial cysts refer to a group of diseases characterized by the presence of non-purulent pathological masses (cysts) in the oral and maxillofacial regions. As the disease progresses, cysts can also become purulent masses due to secondary infection. Cysts grow slowly, and patients often have no subjective symptoms. The main treatment method is surgical removal. Due to the diverse classification of oral and maxillofacial cysts, there are currently no definitive and unified epidemiological data. The incidence of cysts is low in infancy and gradually increases with age, with a high incidence in school-age children.
View detailsApical periodontitis
Periapical periodontitis is an inflammatory disease that occurs in the periapical tissues (including the cementum at the apex of the tooth root, the periodontal ligament, and the alveolar bone). It is mainly characterized by pain, pain when biting, gingival swelling (bulge), and gingival sinus tract (pus discharge). Periapical periodontitis can be divided into acute periapical periodontitis and chronic periapical periodontitis. Acute periapical periodontitis includes: acute serous periapical periodontitis (serous stage), acute suppurative periapical periodontitis (periapical abscess stage, subperiosteal abscess stage, submucosal abscess stage). Chronic periapical periodontitis includes: periapical granuloma, chronic periapical abscess, periapical cyst, and periapical condensing osteitis.
Oral and maxillofacial tumors
Oral and maxillofacial tumors refer to tumors that occur in the oral cavity, salivary glands, maxilla and mandible, face, and neck. They include both benign and malignant tumors. Malignant tumors are commonly carcinomas, with a very small proportion developing into sarcomas. Benign tumors typically present as painless masses, while malignant tumors manifest as expanding indurations, protruding masses, and surface ulcerations, gradually infiltrating surrounding and deeper tissues, accompanied by pain.
View detailsPeriodontal disease
Periodontal disease refers to diseases affecting the supporting tissues of the teeth (periodontium), including gingivitis, which only affects the gingival tissue, and periodontitis, which involves the deeper periodontal tissues (periodontal ligament, alveolar bone, cementum). Periodontal disease is a common oral disease and one of the main causes of tooth loss in adults. It is also a major oral disease that endangers human teeth and overall health.
View detailsPeriodontitis
Periodontal tissues are the tissues surrounding the teeth, primarily functioning to support, stabilize, and nourish the teeth. They include the alveolar bone, gingiva, periodontal ligament, and cementum. Periodontitis is a chronic inflammation that occurs in the periodontal tissues. The inflammation can affect the gingival soft tissues and the deeper supporting tissues of the teeth. In severe cases, it can lead to tooth loosening or loss. This disease commonly affects individuals over 35 years of age. Aggressive periodontitis, however, is more prevalent in adolescents. The main symptoms include red, swollen, and bleeding gums accompanied by halitosis. As the inflammation spreads, periodontal abscesses and tooth loosening may occur.
View detailsPulpitis
Pulpitis is an inflammatory disease of the dental pulp tissue, which can be divided into acute pulpitis, chronic pulpitis, and acute exacerbation of chronic pulpitis. Acute pulpitis is mainly characterized by spontaneous, severe, and often unbearable pain, while chronic pulpitis is primarily characterized by pain triggered by temperature changes.
View detailsDentofacial deformities
Dentofacial deformity, also known as dentomaxillofacial deformity, refers to deformities of the teeth, jawbones, and craniofacial structures caused by congenital genetic factors or acquired environmental factors during a child's growth and development. It mainly manifests as abnormal relationships between the upper and lower jawbones, and between other craniofacial bones, as well as systemic functional abnormalities.
View detailsDental caries
Dental caries, also known as tooth decay or cavities, is primarily caused by bacteria. Under the influence of multiple factors, it leads to chronic and progressive destruction of tooth hard tissues. It can occur in people of any age after the eruption of primary teeth, but is more common in children. It mainly manifests as chalky white or dark brown patches on the tooth surface, some forming cavities, and pain upon probing or temperature stimulation.
