Résumé
To calculate the frequency of dens evaginatus in permanent teeth. Design: A descriptive study. Place and Duration of Study: The study was conducted at Armed Forces Institute of Dentistry [AFID], Rawalpindi from April 2002 to April 2003. Subjects and A clinical and radiographic analysis of 5400 permanent anterior teeth was conducted to determine the occurrence of this developmental malformation. Dens evaginatus was found in about 2.4% of the permanent anterior dentition and was more frequent in the maxilla, particularly in the lateral incisor. This anomaly was less frequent in the mandible. This study shows that dens evaginatus of anterior teeth is more common in the permanent dentition particularly, the maxillary incisors. Furthermore, the frequency of dens evaginatus is high in males than females
