In cariously exposed immature permanent teeth, the treatment choice is controversial in pediatric dentistry. Radical root canal treatment usually appears to be the solution for these teeth. Even partial pulpotomy is a vital treatment for traumatically exposed immature permanent teeth; extending the borders of indication towards cariously exposed immature permanent teeth with reversible pulpitis may abolish the necessity of pulpectomy. This article describes the partial pulpotomy of a cariously affected immature permanent teeth and the follow-up for 1 year. A healthy 11-year-old male patient was referred to Gazi University Faculty of Dentistry Department of Pediatric Dentistry. The patient had reversible pulpitis symptoms on teeth numbered 45. At radiographic examination, immature apex and deep caries lesion were observed and partial pulpotomy was performed by using calcium hydroxide to maintain vitality of the pulp and allow continued development of root dentin expecting the root will attain full maturity. Clinical and radiographic follow-up demonstrated a vital pulp besides not only closure of the apex (apexogenesis), but also physiologic root development (maturogenesis) after 1 year. Partial pulpotomy is an optional treatment for cariously exposed immature permanent teeth for preserving vitality and physiological root development.
在龋源性暴露的未成熟恒牙中，治疗选择在儿童牙科领域存在争议。彻底的根管治疗通常似乎是这些牙齿的解决方案。即使是部分牙髓切断术对于外伤性暴露的未成熟恒牙也是一种重要的治疗方法；将适应证范围扩展至患有可逆性牙髓炎的龋源性暴露未成熟恒牙，可能会消除牙髓摘除术的必要性。本文描述了一颗龋源性受累未成熟恒牙的部分牙髓切断术及1年的随访情况。一名健康的11岁男性患者被转诊至加齐大学牙科学院儿童牙科。患者45号牙有可逆性牙髓炎症状。影像学检查发现根尖未成熟且有深龋病变，遂采用氢氧化钙进行部分牙髓切断术，以维持牙髓活力并使根牙本质持续发育，期望牙根能达到完全成熟。临床和影像学随访显示，1年后牙髓活力尚存，不仅根尖闭合（根尖形成），而且牙根出现生理性发育（成熟形成）。部分牙髓切断术是一种可选择的治疗方法，用于龋源性暴露的未成熟恒牙，以保留牙髓活力和促进牙根生理性发育。
