An 11-year-old female patient was referred with a chief complaint of pain in the right mandibular second premolar. Clinical and radiographic examinations showed secondary caries under an old composite restoration, a negative response to a pulp test and an immature root with an open apex. After root canal cleaning and shaping, bleeding was invoked in the canal up to 2 mm short of the cemento-enamel junction (CEJ). After 10 min to allow clotting at this level, a plug of Biodentine was placed over the blood clot and the tooth was temporized with glass ionomer cement. At the next visit, the tooth was free of symptoms and a permanent filling was placed. Clinical and radiographic examinations during a two-year follow-up showed complete root maturation and intact supporting soft tissues without sinus tract, pain or swelling.
The use of Biodentine in a single-visit apexification protocol to treat an immature permanent tooth with necrotic pulp can create a suitable environment for revascularization, resulting in the completion of root maturation.
一名11岁女性患者因右下颌第二前磨牙疼痛为主诉前来就诊。临床和影像学检查显示,旧复合树脂修复体下方存在继发龋,牙髓测试呈阴性反应,牙根未发育成熟且根尖孔开放。根管清理和预备后,在距牙骨质-釉质界(CEJ)短2 mm处的根管内引发出血。10分钟后,在此水平让血液凝固,在血凝块上放置一块BioDentine,并用玻璃离子水门汀暂时封闭患牙。下次复诊时,患牙无症状,进行了永久性充填。两年随访期间的临床和影像学检查显示牙根完全成熟,支持软组织完整,无窦道、疼痛或肿胀。
在一次性根尖诱导成形术方案中使用BioDentine治疗牙髓坏死的未成熟恒牙,可为血管再生创造适宜环境,从而实现牙根成熟。
