Conjoining abnormalities occur in less than 1 percent of the population. Triplication of primary teeth is even a rarer phenomenon with a prevalence of 0.02 percent. This study describes the clinical features and the light microscopic appearance of a case of triplicated primary teeth. The teeth with the conjoined defect were examined by light microscopy to evaluate the exact level and appearance of the fusion area. The light microscopic examination revealed grooves and cracks consisting of enamel and dentine in the fusion area, fusion was irregular and both dentin and cementum were confluent. It is concluded that the clinician should identify children were conjoined anomalies and should be aware of the oncoming problems.
连体畸形在不到1%的人口中出现。乳牙三联症更是一种罕见现象，患病率为0.02%。本研究描述了一例乳牙三联症的临床特征和光学显微镜下的表现。对伴有连体缺陷的牙齿进行光学显微镜检查，以评估融合区域的确切水平和外观。光学显微镜检查显示，融合区域有由釉质和牙本质组成的沟和裂纹，融合不规则，牙本质和牙骨质均融合。结论是，临床医生应识别患有连体畸形的儿童，并应意识到随之而来的问题。
