Frequency of dens evaginatus of permanent anterior teeth

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

Comparison of vertical with lateral condensation technique in obturation of root canal system

To compare vertical condensation with laterally condensed gutta-percha technique in obturation of root canal system. Design: A comparative study. Place and Duration of Study: The Armed Forces Institute of Dentistry [Operative Deptt], Rawalpindi. Subjects and Fifty six human permanent extracted teeth were collected from central incisor to second molar from the both arches and in vitro root canal procedure was carried out. Warm vertical technique resulted in a uniform smooth surface and least observable space between gutta percha and canal wall, especially in middle and apical region. Root canal obturation by warm vertical condensation is better than cold lateral condensation

Autotransplantation of endodontically treated third molars

To determine the success rate in autotransplantation of endodontically treated third molars. Design: A descriptive study. Place and Duration of Study: This study was carried out at Armed Forces Institute of Dentistry [AFID], Rawalpindi [Pakistan] from January 2002 to December 2002. Patients and A total of 50 patients meeting the inclusion criteria were selected who had their first or second molars in unrestorable condition with intact third molars. The donor teeth were extracted after the preparation of recipient site. After endodontically treated in vitro the donor teeth were carried to the recipient site and immobilized. Postoperative variables were recorded and analyzed on SPSS version 10. The overall success rate after six months of the transplantation of third molars was 88% with complete root formation after endodontic treatment. All the patients[12%] who had complaints were more than 35 years of age. Third molars are good substitute for the unrestorable first or second molars and would be as effective as endosseous implants. The procedure is likely to have complications in the advanced age group
