南方医科大学深圳口腔医院（坪山）牙体牙髓病科近期正式开设活髓保存专病门诊和根管再治疗专病门诊1。这两个专科采用现代牙髓生物学理念，通过先进诊疗技术为患者提供微创天然牙保存治疗，改变了过去牙髓炎症只能进行根管治疗或拔牙的单一选择1。
活髓保存治疗适用于深龋近髓、意外露髓、外伤导致牙神经暴露、部分不可复性牙髓炎、年轻恒牙牙髓损伤等情况1，可通过间接盖髓、直接盖髓、部分或冠髓切断术等方式在轻度牙髓损伤时保留牙髓活力1。根管再治疗专科则为既往根管治疗失败的患牙提供二次救治机会1，适用于既往根管治疗后仍疼痛、牙龈反复肿胀、咬合不适、影像发现根尖炎症未愈合等情况1。
天然牙具有不可替代的咀嚼、感觉和生物学功能，保留天然牙比拔牙后种植更有利于口腔长期健康1。
Southern Medical University Shenzhen Oral Hospital (Pingshan) has recently launched two specialized clinics within its Department of Endodontics: a vital pulp preservation clinic and an endodontic retreatment clinic 1. These services represent a shift away from the traditional approach of root canal treatment or tooth extraction as the sole options for pulp inflammation 1.
The vital pulp preservation treatment can retain pulp vitality in cases of mild pulp injury through techniques such as indirect pulp capping, direct pulp capping, partial pulpotomy, or complete coronal pulpotomy 1. This approach applies modern pulp biology principles to address conditions including deep caries near the pulp, accidental pulp exposure, traumatic nerve exposure, certain cases of irreversible pulpitis, and pulp injury in young permanent teeth 1. The endodontic retreatment clinic serves patients whose previous root canal treatment has failed, addressing symptoms such as persistent pain, recurrent gum swelling, bite discomfort, or radiographic evidence of unresolved apical inflammation 1.
By preserving natural teeth through these minimally invasive treatments, the hospital aims to maintain the irreplaceable chewing, sensory, and biological functions that natural teeth provide 1. Retaining natural teeth offers greater long-term benefits for oral health compared to extraction followed by implant placement 1.
