Dens invagination is a developmental anomaly requiring specific treatment approaches. Oehler's Type III dens in dente, extends into the root and perforates at the apical area or lateral surface of the root. In this case endodontic treatment of the invaginated tooth was carried out through the central lumen of the invagination with calcium hydroxide without manipulation of the main pulp canal, thereby leaving the tooth vital. The 18-month follow-up examinations were indicative of treatment success; the periapical lesion resolved completely and the tooth remained vital.
Information about the three dimensional anatomy of the teeth especially those with an abnormality is necessary for a successful treatment.
牙内陷是一种需要特定治疗方法的发育异常。奥勒(Oehler)III型牙中牙,延伸至牙根并在根尖区或牙根侧面穿孔。在该病例中,对陷入牙通过陷入中央管腔进行氢氧化钙根管治疗,而不处理主牙髓管,从而使牙齿保持活力。18个月的随访检查表明治疗成功;根尖病变完全消退,牙齿保持活力。
对于成功治疗而言,了解牙齿尤其是异常牙齿的三维解剖结构信息很有必要。
