Résumé
The management of two unusual cases of dens invaginatus and talon cusp is presented. The first concerns talon cusp in maxillary primary and permanent lateral incisors, a supplemental tooth with dens invaginatus hampering eruption of the permanent incisors. The other present with bizarre crown morphology of a lateral incisor with talon cusp, dens invaginatus and a palatal accessory cusp-like structure. Early diagnosis and management are important to avoid complications.

The management of two cases of hypertaurodontism, is presented. The first case shows this uncommon dental anomaly in all the four permanent first molars. The second case is concerned with endodontic management of a hypertaurodontic mandibular second premolar. The authors wish to highlight the importance of careful radiographic examination in diagnosing this rare dental anomaly in view of the difficulties encountered in performing endodontic treatment.

Papillon Lefevre Syndrome is a rare syndrome autosomal recessive in nature, manifesting as keratosis palmoplantaris with periodontitis. A case of Papillon Lefevre Syndrome present in a 12 year old boy is presented. Only the permanent maxillary canines were present in the oral cavity when the patient was first seen, and despite efforts towards preservation, they had to be extracted. (complete dentures were made and the patient was followed up for 26 months.

Supernumerary or extra teeth result from disturbances during the initiation and proliferation stages of dental development. Teeth formed in excess of the normal number are termed supernumerary teeth. A supernumerary tooth may closely resemble the teeth of the group to which it belongs i.e. molars, premolars or anterior teeth or it may bear little resemblance in size or shape to the teeth with which it is associated. Discussed here are reports of three cases with multiple supernumerary teeth in the mixed dentition and its management.
