Abstract

There are many reasons for tooth discoloration. An increase in the bilirubin level may cause tooth discolorations. Such cases are rare, but most involve tooth discoloration with a greenish hue. The purpose of this case report is to describe green discoloration of the primary dentition in the presence of neonatal hyperbilirubinemia. 2 boys aged 16 and 22-months presented with chief complaints of erupting teeth of abnormal color. Their primary teeth exhibited a greenish discoloration along enamel hypoplasia. Both patients were born prematurely with a low birth weight and had been diagnosed with neonatal hyperbilirubinemia. Systematic diseases can affect the hard tissue of teeth during their formation and result in changes in tooth color. Periodic follow-ups are required for establishing a normal dental condition and meeting the esthetic needs of patients. A pediatric dentist may be the first person to observe patients with discoloration in their primary dentition. In such cases the dentist can deduce the systematic disease responsible for this discoloration.

치아 변색을 일으키는 다양한 원인들이 있다. 혈중 빌리루빈의 증가도 치아변색을 일으킬 수 있는데 이는 드문 경우이나, 대부분 초록색 변색이 보고 되었다. 본 증례는 신생아 고빌리루빈혈증 병력이 있는 환아의 유치의 초록색 변색에 대한 것이다. 16개월, 22개월 두 남아가 맹출한 치아의 비정상적인 색을 주소로 내원하였다. 두 환아의 유치는 법랑질저형성증을 수반한 초록색 변색을 보였다. 두 환아 모두 저체중, 조산아였으며, 신생아 고빌리루빈혈증을 진단받았다. 전신적인 질환은 치아의 형성시기에 경조직에 영향을 줄 수 있으며, 변색도 일으킬 수 있다. 정상적인 치아 발육과 환아의 심미적 요구를 충족시키기 위해 정기적인 관찰이 필요하다. 소아치과의사는 유치열기의 변색을 먼저 관찰 할 수 있다. 이와 같은 증례들을 통해 치과의사는 치아변색에 대해 전신적 질환을 추론할 수 있다.
