Clinical and radiographic evaluation and comparison of six cases of fusion involving the primary dentition

摘要

Fusion occurs infrequently, but could cause esthetic, spacing, and periodontal problems. An understanding of fused teeth and their associated problems is important to provide prophylactic measures, thereby preventing or minimizing possible complications. The purpose of this case report was to highlight the infrequency of fused primary teeth by virtue of the number of such cases reported in the literature. Six cases of asymptomatic dental twinning anomalies in the primary dentition are reported in this study, and a clinical and radiographic presentation of the cases of fusion of primary incisor teeth is illustrated. This clinical entity has been found to appear with varied clinical and radiographic appearances. All cases are different from each other. This study's fourth patient is of particular interest because he is the second known case of bilateral fusion of the primary mandibular central and lateral incisors to be reported in the literature. An association of fusion of primary incisors with the number of succedaneous teeth was observed.
