Abstract
Ten cases on and after mixed dentition were clinico-histopathologically diagnosed as epulis at the Pedodontic Clinic of Niigata University Dental Hospital during a period of 13 years and 9 months from September 1979 to May 1993. We analysed those cases and compared them with 11 cases of epulis in the deciduous dentition.
The results were as follows:
1. The patients consisted of 2 males and 8 females. The age of the patients ranged from 6 years to 28 years. Two patients were adults, one had autism and another was mentally-retarded, both without prescription of anticonvulants.
2. Four patients came with tumor of the gingiva as their chief complaints, and others showed lesions during the dental treatments or dental check-ups.
3. Seven cases occurred in the maxilla; six were located in the anterior segments and one in the posterior, and three in the mandible; two in the anterior and one in the posterior.
4. All of the lesions were smaller than 10 mm in diameter.
5. Histopathologically, all of the cases showed inflammatory epulis. One case showed epulis granulomatosa,3 cases epulis granulo-fibrosa,6 cases epulis fibrosa.
6. The tumors were removed surgically in 9 cases. In one case, the tumor disappeared after biopsy. The prognosis is good and no recurrence has been observed to date.
7. The etiological factors were considered to be tooth eruption, labial arch appliance, trauma, mobile tooth, and so on.
