Dentin dysplasia (DD) Type I is a developmental condition affecting dentin, inherited in an autosomal-dominant pattern or occurring due to a new mutation. Whilst the crowns of DD Type I affected teeth appear clinically normal, the roots are blunt and shortened. Pulp necrosis and periapical pathoses may be seen in the absence of obvious causes. Pulp stones and calcifications are frequently encountered. Endodontic management of DD may be challenging. A case of DD Type I, sub-classification d, in which spontaneous irreversible pulpitis developed on three mandibular incisors is documented. The case was managed by conventional endodontic treatment. Knowledge of this uncommon dental condition may assist dentists to adequately diagnose and manage these cases. Extraction should not be considered the first-line treatment option when sufficient root length is available to attempt endodontic treatment. Referral for medical evaluation is recommended to rule out systemic diseases which may mimic this condition.
牙本质发育不全（DD）I 型是一种影响牙本质的发育性疾病，以常染色体显性遗传模式遗传，或由于新的突变而发生。虽然 DD I 型受累牙齿的牙冠在临床上看起来正常，但牙根钝且缩短。在没有明显原因的情况下，可能会出现牙髓坏死和根尖周病。牙髓结石和钙化经常发生。DD 的牙髓治疗可能具有挑战性。本文记录了一例 DD I 型，亚类 d，在三颗下颌切牙中发生自发性不可复性牙髓炎。该病例通过常规根管治疗进行管理。了解这种不常见的牙科状况可能有助于牙医充分诊断和治疗这些病例。在有足够的牙根长度尝试根管治疗时，不应将拔牙视为一线治疗选择。建议进行医学评估以排除可能模仿这种情况的全身性疾病。
