AIMS AND BACKGROUND
The success of endodontic treatment in open apex teeth depends on the establishment of an ideal apical barrier so that apical canal space between the periodontium and the root canal system is filled. Biodentine is a calcium silicate-based cement having several advantages over mineral trioxide aggregate (MTA), glass ionomer cement (GIC), and calcium hydroxide in the treatment of teeth with open apices. Orthograde delivery of biodentine is technique-sensitive and requires multiple radiographs for verification, as well as retrograde placement of biodentine requires surgical intervention. To use the advantages of biodentine and to overcome the disadvantages of placement techniques, an innovative technique was done to obturate the tooth with an open apex using a custom-fit prefabricated BioRoot inlay in this case report.
CASE DESCRIPTION
In the present case, biodentine has been used as a BioRoot inlay to overcome the disadvantages of various management options of open apex with parallel dentinal walls. BioRoot inlay is an intraradicular custom-made prefabricated restoration which provides the three-dimensional seal of the root canal space and promotes an apical barrier formation in a wide-open apex. This BioRoot inlay, placed passively in the canal, had a good seal laterally and apically along with the Biodentine as sealer forming a monoblock. This sealer helps in sealing milder discrepancies between the plug and the root, providing a three-dimensional seal which had resulted in good healing of periradicular bone.
CONCLUSION
Biodentine, when used as BioRoot inlay, has been shown to induce faster periapical healing. It provides promising results when used in open apices with parallel walls. It establishes three-dimensional obturation and proper apical seal, which promotes effective root-end induction.
CLINICAL SIGNIFICANCE
It can be considered as the effective and definitive alternative for nonsurgical and surgical approaches to treating open apex.

目的与背景
根尖孔开放牙齿的根管治疗成功与否取决于建立理想的根尖屏障，从而填充牙周组织与根管系统之间的根尖管间隙。生物活性牙本质是一种硅酸钙基水门汀，在治疗根尖孔开放的牙齿方面，相对于矿物三氧化物凝聚体（MTA）、玻璃离子水门汀（GIC）和氢氧化钙具有若干优势。生物活性牙本质的顺行输送对技术要求较高，需要多张X光片进行验证，而且生物活性牙本质的逆行放置需要手术干预。为了利用生物活性牙本质的优势并克服放置技术的缺点，在本病例报告中采用了一种创新技术，使用定制的预制BioRoot嵌体来充填根尖孔开放的牙齿。
病例描述
在本病例中，生物活性牙本质被用作BioRoot嵌体，以克服根尖孔开放且牙本质壁平行的各种治疗方法的缺点。BioRoot嵌体是一种根管内定制的预制修复体，可提供根管空间的三维密封，并促进宽大开髓孔的根尖屏障形成。这种被动放置在根管内的BioRoot嵌体，与作为封闭剂的生物活性牙本质一起，在根管侧方和根尖具有良好的密封性，形成一个整体。这种封闭剂有助于封闭充填体与牙根之间的轻微缝隙，提供三维密封，从而使根尖周骨得到良好愈合。
结论
生物活性牙本质用作BioRoot嵌体时，已显示出能诱导更快的根尖周愈合。在根尖孔开放且牙本质壁平行的情况下使用时，它能提供有前景的结果。它建立了三维充填和适当的根尖密封，促进了有效的根尖诱导。
临床意义
它可被视为治疗根尖孔开放的非手术和手术方法的有效且确定性替代方案。
