Abstract

Morphological variations are seen in both primary and permanent dentitions. Cusp of Carabelli is also one of them. It is suggested that it is due to over activity of dental lamina but definitive aetiology is unknown. It is a type of accessory cusp, occurs more often in permanent maxillary first molars, whereas, its occurrence in primary tooth is rare. The present case series discusses the presence of cusp of Carabelli in primary maxillary second molars in three different cases. This case series will help clinicians to identify, diagnose and take proper preventive care and also adds to the incidence in literature.

摘要

在乳牙列和恒牙列中均可见形态变异。卡氏尖就是其中之一。有人认为这是由于牙板活动过度，但确切病因尚不清楚。它是一种额外牙尖，更常见于恒牙上颌第一磨牙，而在乳牙中很少见。本病例系列讨论了三例不同病例中乳牙上颌第二磨牙出现卡氏尖的情况。该病例系列将有助于临床医生识别、诊断并采取适当的预防措施，同时也增加了文献中的发病率。
