Introduction: Supernumerary anterior teeth are a frequent cause of alterations in the eruption of permanent teeth. These alterationes can be minimized if the removal of the supernumerary is done at the right moment. The objectives of this study were to evaluate alterations in permanent teeth and the influence of the age of the patient on the evolution. Material and methods: 125 pediatric patients who presented unerupted supernumerary anterior teeth were studied during the period 1994-2000. The factors analized were the patient´s age, characteristics of the supernumerary teeth and alterations in the eruption of permanent teeth, as well as post-surgical evolution. Results: The mean age was 9,9 years. 77% of the study population were male. In 69,6% of the cases,eruptive alterations in permanent teeth were seen. Of this group, after surgery, 41,4% erupted spontaneously, 11,5% erupted ectopically and 47,1% did not erupt at all. When relating the age of the patient to the failure of eruption, there was a statistically significant relationship. The patients treated before age 9,  had favourable results. Conclusions: The presence of unerupted anterior supernumerary teeth is associated with eruptive alterations on permanent teeth. The age of the patient at the time of treatment influences the evolution of the permanent teeth.
