A CASE OF COMBINED DENTAL DEVELOPMENT ABNORMALITIES - IMPORTANCE OF ATHOROUGH EXAMINATION

This report describes a case of combined dental development abnormalit ies. A patient with a previous ectopically erupted supernumerary maxil lary canine presented a new ectopically erupted supernumerary premaxil lary tooth with dens invaginatus (Oehlers' type 2) and an aberrant cor onal morphology, including a pit in the distal portion of the palatal surface. This tooth would have been diagnosed earlier if a panoramic r adiograph had been taken at the first visit 5 months before. This case represents a good example of combined dental development abnormalitie s, i.e., a numerical anomaly (the supernumerary tooth), an alteration of dental position (the ectopic eruption), an alteration of dental mor phology (the aberrant coronal shape), and the invagination. This case highlights the importance of a thorough examination, including complem entary radiography, of patients with a dental anomaly.
