The present study was to examine the radiographic and histologic correlation of the respective ultrasonographic findings.
Histologic examinations were performed in 12 fetuses who had died in utero between 16 and 34 weeks of gestation. The fetuses had been examined by intrauterine sonography for tooth germs and had been subjected to additional radiographic examinations post abortum or partum. During autopsy, the tooth germs were again examined sonographically and radiographically, and non-decalcified histological sections were obtained by means of the sawing and grinding technique.
The results obtained by histologically examining the 12 fetal jaws in the ultrasonic plane corresponded in all cases to those examined by sonography and radiology.
Sonographic proof of tooth germs might gain increasing importance in future because agenesia of tooth germs is one of the principal signs of a variety of hereditary syndromes, particularly those of ectodermal origin.
本研究旨在探讨超声检查结果与X线及组织学检查结果之间的相关性。
对12例妊娠16至34周死于宫内的胎儿进行组织学检查。这些胎儿在宫内已接受过牙胚超声检查，并在流产或分娩后接受了额外的X线检查。尸检时，再次对牙胚进行超声和X线检查，并采用锯切和研磨技术获取未脱钙组织切片。
对12例胎儿颌骨在超声平面上进行组织学检查所获得的结果，在所有病例中均与超声及X线检查结果相符。
牙胚的超声检查证据在未来可能会变得越来越重要，因为牙胚发育不全是多种遗传性综合征（尤其是外胚层起源的综合征）的主要体征之一。
