摘要

本文提出的臨床病例報告為一位五歲的男童,在左上乳側門齒區有一多生牙，並且與左上乳犬齒fusion。根據統計，乳牙發生多生牙的機率僅有0.44% (Morioka et ai, 1991)；發生fusion的機率大約有0.5% (Grahanen & Granath, 1961 )；好發生在下顎前牙，乳齒齒列時發生於乳側門齒典乳犬齒最常見，而當乳齒多生牙伴隨fusion的盛行率更是罕見。(Taiwan J Pediatr Dent 2(4): 116-120, 2002)

We reported a 5 year-old boy with a fused tooth of the maxillary primary left canine. This fused tooth is composed of a primary canine and a supernumerary tooth, which is similar to a primary lateral incisor. The prevalence of supernumerary teeth in Chinese reported by Morioka et a1 (1991) is 0.44%, was calculated excluding mesiodens. Fusion has an incidence of 0.5% and is more common in the primary dentition (Grahanen and Granath, 1961). Fusion occurs most common in the anterior teeth. When present in the primary dentition, fusion usually occurs in the mandibular lateral incisors and canines. Supernumerary tooth fused with a normal tooth has rarely been presented.
