The restorative management of deep carious lesions and the preservation of pulp vitality of immature teeth present real challenges for dental practitioners. New tricalcium silicate cements are of interest in the treatment of such cases. This case describes the immediate management and the follow-up of an extensive carious lesion on an immature second right mandibular premolar. Following anesthesia and rubber dam isolation, the carious lesion was removed and a partial pulpotomy was performed. After obtaining hemostasis, the exposed pulp was covered with a tricalcium silicate cement (Biodentine, Septodont) and a glass ionomer cement (Fuji IX extra, GC Corp.) restoration was placed over the tricalcium silicate cement. A review appointment was arranged after seven days, where the tooth was asymptomatic with the patient reporting no pain during the intervening period. At both 3 and 6 mon follow up, it was noted that the tooth was vital, with normal responses to thermal tests. Radiographic examination of the tooth indicated dentin-bridge formation in the pulp chamber and the continuous root formation. This case report demonstrates a fast tissue response both at the pulpal and root dentin level. The use of tricalcium silicate cement should be considered as a conservative intervention in the treatment of symptomatic immature teeth.
对于牙科医生而言,对深龋病变进行修复性治疗以及保留未成熟恒牙的牙髓活力是一项切实的挑战。新型硅酸三钙水门汀在这类病例的治疗中备受关注。本病例描述了对右侧下颌第二未成熟前磨牙广泛龋损的即刻处理及随访情况。在局部麻醉并使用橡皮障隔离后,去除龋损组织并进行了部分活髓切断术。止血后,用硅酸三钙水门汀(Biodentine,Septodont公司)覆盖暴露的牙髓,然后在硅酸三钙水门汀上方放置玻璃离子水门汀(Fuji IX extra,GC公司)进行修复。七天后安排了复诊,期间患牙无症状,患者表示未感到疼痛。在3个月和6个月的随访中,发现患牙活力正常,对温度测试反应正常。对该牙的影像学检查显示髓腔内有牙本质桥形成且牙根持续发育。本病例报告表明在牙髓和牙根牙本质层面均有快速的组织反应。在有症状的未成熟恒牙治疗中,应考虑使用硅酸三钙水门汀作为一种保守的干预措施。
