Results: Among 1043 cases included in the current study, only three infants had the natal teeth. Here, prevalence is 0.29%. Conclusion: The causes of natal teeth, which are not mesiodens, remain unknown. However, for any clinical procedure, the punctilious examination and communication with the parents are necessary to avoid any potential misunderstandings.
