Abstract

Introduction: Dens invaginatus (DI) and Dens evaginatus (DE), the developmental anomalies affecting the morphology of the tooth structure are extremely rare to occur. DI occurs because of invagination of a crown into dental papillae. DE is a tubercular emergence from occlusal surfaces of posterior teeth and lingual surfaces of anterior teeth. The two anomalies on separate teeth are frequently mentioned, but their co-occurrence in a single tooth is a rare entity.

Patient concerns: A 20-year-old male patient presented with the rare combination of DE and DI on a dilacerated maxillary right lateral incisor diagnosed using cone beam CT. Treatment: The patient was managed conservatively and is undergoing fixed orthodontic treatment for malocclusion. Despite its uniqueness, very few localized cases have been documented.

Takeaway lessons: These anomalies act as an etiological factor for several dental problems for neighboring & opposing tooth. Early diagnosis of such anomalies should be done so that prophylactic management can be initiated.

利用锥形束计算机断层扫描诊断的上颌侧切牙缺损中的 "畸形牙 "和 "畸形牙"--病例报告和文献综述。
导言:内陷牙(Dens invaginatus,DI)和外陷牙(Dens evaginatus,DE)是影响牙齿结构形态的发育异常,极为罕见。内陷牙(DI)是由于牙冠内陷于牙乳头。DE是后牙的咬合面和前牙的舌面出现结核。这两种异常在不同的牙齿上经常被提及,但同时出现在一颗牙齿上的情况却很少见:一名 20 岁的男性患者通过锥形束 CT 诊断出,他的上颌右侧切牙扩张,罕见地同时存在 DE 和 DI。治疗患者接受了保守治疗,目前正在接受错颌畸形固定矫正治疗。尽管这种情况很独特,但很少有局部病例的记录:这些异常是导致邻牙和对生牙出现多种牙科问题的病因。应及早诊断此类异常,以便采取预防措施。
