Abstract
Fused deciduous teeth can be found with a high incidence in the clinical area of pediatric dentistry. However, the incidence of fused permanent teeth is lower than that of fused deciduous teeth. A 12year one-month old boy presented with a case of fused permanent teeth involving the maxillary anterior teeth (fused teeth of the right central incisor and lateral incisor) which is one of the rarest exampies among fused permanent teeth cases. We report here the results of the dental evaluation of this case.
1. According to the answers to the questionnaire, the fused deciduous teeth were not found during the deciduous dentition.
2. When the mesio-distal crown size of_??__??__??_was measured separately,1 showed a value less than -3S. D. while_2_was within the average range.
3. Except_??__??__??_and_5, the mesio-distal crown size of all maxillary teeth were within the average range.
4. Using roentgenographic cephalometry, it was indicated that the size of the maxilla and those of the mandible were within normal ranges.
