View detailsWarthin's tumor
Warthin's tumor, also known as papillary cystadenoma lymphomatosum or adenolymphoma, is one of the common benign tumors of the salivary glands, and its histogenesis is related to lymph nodes. The etiology of this disease is still unclear, but it may be associated with smoking. It mainly presents as a slow-growing, painless mass located in the posterior-inferior pole of the parotid gland.
Dentin hypersensitivity
Dentin is the yellowish tissue that forms the bulk of the tooth, located between the enamel and the pulp. Dentin hypersensitivity, commonly known as sensitive teeth, refers to the transient, sharp pain or discomfort that occurs when teeth are exposed to external stimuli such as cold, heat, sweet, sour, or mechanical forces, due to exposed dentin. This condition is most prevalent in individuals aged 50-59 years. The number of affected women is significantly higher than men, and the severity is also greater in women. The main symptom is a brief and sharp pain or discomfort after the tooth is stimulated.
View detailsMucocele
A mucocele is a cyst formed by the retention of secretions within a mucous gland due to obstruction of its excretory duct, leading to gradual expansion of the acini. Since mucous glands are primarily distributed in the oral cavity, mucoceles predominantly occur there, commonly found on the lower lip and tip of the tongue. Mucoceles appear as translucent, bluish, blister-like cystic protrusions in the oral cavity. They are soft and elastic, typically ranging in size from a soybean to a broad bean.
View detailsSoft Palate Paralysis
Palatal paralysis refers to a disease characterized by abnormal neuromuscular activity of the soft palate due to central or peripheral lesions, leading to impaired soft palate movement. Unilateral palatal paralysis is generally asymptomatic, while bilateral palatal paralysis presents with obvious symptoms, such as slurred speech, food regurgitation during swallowing, and restricted facial movement.

Maxillary sinus odontogenic cyst refers to a cyst formed in the maxillary sinus due to tooth development disorders or lesions. According to the origin of the cyst, this disease can be divided into two types: dentigerous cyst (also known as follicular cyst) and radicular cyst. Common symptoms of this disease include nasal obstruction, cheek bulging, and upward displacement of the eyeball.
View detailsRanula
A sublingual cyst is a cyst formed by the obstruction of the sublingual gland or submandibular gland duct, or by the extravasation of secretions due to duct rupture. The cyst is usually located on one side of the floor of the mouth under the tongue, with a thin wall, a purplish-blue color, and a fluctuating sensation upon palpation.
View detailsGingival hyperplasia
Gingival hyperplasia, also known as gingival overgrowth, refers to an increase in the volume of gingival tissue due to an increase in the cellular components of the gingiva. It can be observed in infectious diseases of the gingival tissue caused by dental plaque biofilm, as well as in non-inflammatory changes caused by factors other than local irritation. It is common in adolescents during puberty, pregnant women, and individuals who have been taking drugs such as nifedipine, cyclosporine, and phenytoin sodium for a long time.
