What are the common diseases in dentistry?

There are various common diseases in dentistry, mainly including dental pulp diseases, periodontal diseases, oral mucosal diseases, and oral surgical diseases. Specifically, common dental pulp diseases include dental caries, pulpitis, and periapical periodontitis, which may cause tooth pain, defects, and even tooth loosening. Periodontal diseases, such as gingivitis and periodontitis, are characterized by symptoms like gingival bleeding, redness, swelling, and pain, and can lead to tooth loss in severe cases. Oral mucosal diseases, such as oral ulcers and lichen planus, may affect the normal function of the oral mucosa, causing pain and discomfort. Oral surgical diseases include zygomatic fractures, jaw fractures, and dental trauma, which often require surgical treatment. In addition, oral diseases also include some more severe conditions, such as oral cancer, which require early detection and treatment. Therefore, maintaining good oral hygiene and undergoing regular dental checkups are essential.
