Abstract: On routine medical checkups of 1st MBBS students during the admission into medical college,2 boy students were found to have persistent primary mandibular central incisors and 1 girl student was found to have only 2 maxillary incisors instead of 4 in the upper jaw where the lateral maxillary incisors were missing. In the first two cases, on inspection of dentition of both boys, the primary milk teeth were present in the mandible only. These were small when compared to other secondary dentition. Gums were normal. There was no eruption of permanent mandibular central incisors. The primary teeth were as strong as the other permanent teeth. There was no considerable difficulty in speech or mastication.
