Abstract：
Taurodontism is a morphological anomaly involving multirooted teeth that is characterized by a vertical shift of the pulp chamber and shortening of the roots. The literature was analyzed to determine the impact of a diagnosis of taurodontism on dental treatment. A total of 85 full-text publications from the years 2005-2021 were analyzed and 20 publications were included in this research. The endodontic treatment of a taurodont tooth is challenging due to the apical displacement of the pulpal chamber floor and the incorrect configuration of the root canal system, or the presence of additional canals. In terms of prosthetics, the use of taurodont teeth as abutments is not recommended as they lack stability due to shorter roots. The extraction of taurodont teeth can be complicated due to an apical shift of the root furcation. In periodontology, taurodont teeth can have a better prognosis as there is less chance of furcation involvement. From an orthodontic point of view, it is important to note that taurodont teeth are not sufficiently embedded in the alveolus and have a greater tendency for root resorption. With regard to genetic diseases, it has been reported that this anomaly can exist as an isolated feature. However, the majority of authors agree that taurodontism is associated with conditions such as Down syndrome, Klinefelter syndrome, cleft lip and palate, hypodontia, amelogenesis imperfecta, and others. From a clinical standpoint, it is very important to diagnose taurodontism before treatment. A diagnosis of taurodontism can be important in the early diagnosis of malformations that commonly occur with this condition.
摘要：
Taurodontism是一种形态异常，涉及多根牙齿，其特征在于牙髓腔的垂直移动和根部的缩短。对文献进行了分析，以确定诊断为牙体病对牙科治疗的影响。对2005-2021年的85篇全文出版物进行了分析，本研究包括20篇出版物。由于牙髓腔底板的根尖移位和根管系统的不正确配置，对牛磺酸牙的牙髓治疗具有挑战性，或额外的运河的存在。在假肢方面，不建议使用牛磺齿作为基台，因为它们由于根部较短而缺乏稳定性。由于根分叉的根尖移位，牛磺酸牙的拔除可能很复杂。在牙周学中，由于分叉参与的机会较少，因此牛磺酸牙可以有更好的预后。从正畸的角度来看,重要的是要注意，牛磺酸牙没有充分嵌入肺泡中，并且有更大的根吸收趋势。关于遗传疾病，据报道，这种异常可以作为一个孤立的特征存在。然而,大多数作者认为，牛磺酸症与唐氏综合症等病症有关，Klinefelter综合征,唇腭裂,缺省症,釉质发育不全,和其他人。从临床的角度来看，在治疗前诊断牛磺酸症非常重要。在这种情况下通常发生的畸形的早期诊断中，对牛磺酸症的诊断可能很重要。
