Dens evaginatus (DE) is a dental anomaly with a supernumerary tubercle projection that typically contains dentin and pulp tissue. However, the tubercle projection can fracture, exposing the dentin and potentially the dental pulp, which induces pulpal diseases. Managing DE should be primarily based on the clinical diagnosis of the pulp.
The literature search in prevalence, prophylaxis, and management of dens evaginatus was performed in PubMed database as well as by manual search, in which the related contents were collected and descriptively analyzed.
Of the 264 searched literatures, 62 articles were included for this scoping review. The prophylactic management of the tubercle of DE teeth with a normal pulp should be performed as early as possible by the prep-and-fill technique or the reinforcement technique to preserve tooth vitality and continued root development, with the former reported to be superior compared with the latter. Furthermore, DE teeth with reversible pulpitis should be managed with the prep-and-fill technique. For DE teeth with irreversible pulpitis, vital pulp therapy, ie, partial or full/coronal pulpotomy, should be considered when the pulpal inflammation is limited to the coronal pulp to preserve the vitality of the radicular pulp that induces apexogenesis. A pulpectomy should be performed if the pulpal inflammation has progressed into the radicular pulp. For DE teeth with pulpal necrosis (or after pulpectomy) and immature roots, mineral trioxide aggregate apexification or regenerative endodontic procedures are the treatment options. For DE teeth with pulpal necrosis and complete root formation, nonsurgical root canal treatment is the treatment of choice. A flow chart of the decision-making for managing DE teeth based on pulpal diagnosis is proposed.
DE teeth should be properly managed, by prophylaxis or treatment, depending on pulpal diagnosis and related factors.
齿凹(DE)是一种牙齿异常,具有额外的结节状突起,通常包含牙本质和牙髓组织。然而,结节状突起可能会断裂,暴露出牙本质,并可能暴露出牙髓,从而引发牙髓疾病。DE 的处理应主要基于牙髓的临床诊断。
在 PubMed 数据库中进行了关于 DE 的流行率、预防和管理的文献检索,并进行了手动搜索,收集并描述性分析了相关内容。
在检索到的 264 篇文献中,有 62 篇文章被纳入本范围综述。对于具有正常牙髓的 DE 牙齿的结节,应尽早通过预备和填充技术或加固技术进行预防性处理,以保持牙齿活力和持续的牙根发育,前者被报道优于后者。此外,对于可逆性牙髓炎的 DE 牙齿,应采用预备和填充技术进行处理。对于不可逆性牙髓炎的 DE 牙齿,如果牙髓炎症仅限于冠部牙髓,以保持诱导根尖形成的根髓活力,可以考虑活髓治疗,即部分或全冠牙髓切断术。如果牙髓炎症已经进展到根髓,则应进行牙髓切除术。对于有牙髓坏死(或牙髓切除术后)和未成熟根的 DE 牙齿,可选择使用三氧化矿物聚合体根尖诱导成形术或再生性牙髓治疗。对于有牙髓坏死和完全根形成的 DE 牙齿,非手术根管治疗是首选的治疗方法。提出了一种基于牙髓诊断的 DE 牙齿处理决策流程图。
根据牙髓诊断和相关因素,DE 牙齿应通过预防或治疗进行适当处理。
