11 patients with radio-opaque concrements in the sinus maxillaris underwent a preoperative computerized tomographic examination of the sinus maxillaris and the sinus concrements. 8 patients (72.7%) with the occurrence of radio-opaque concrements presented postoperative a histological and microbiological infection with aspergillus fumigatus. The CT-numbers of radio-opaque concrements in patients with aspergillus were 2802 +/- 302.4 HU (Hounsfield Unit). Concrements of patients without aspergillus infection (n = 3) had lower density (368.6 +/- 149.1 HU; p < 0.001). The root filling materials showed nearly the same CT-numbers in patients with aspergillus infection (2537 +/- 398.5 HU) and in patients without aspergillus infections (2544.3 +/- 460.6 HU). Density of root filling material was at the same level as density of radiopaque concrements in patients with aspergillus infections. According to CT-examinations a direct connection between root filling materials and aspergillus infection was noted. Therefore in patients with radio-opaque concrements computerized tomographic examination helps to determine the kind of sinus infection.
11例上颌窦内有不透X线结石的患者接受了术前上颌窦及窦内结石的计算机断层扫描检查。8例（72.7%）出现不透X线结石的患者术后出现了烟曲霉的组织学和微生物学感染。感染烟曲霉患者的不透X线结石的CT值为2802±302.4 HU（亨氏单位）。未感染烟曲霉的患者（n = 3）的结石密度较低（368.6±149.1 HU；p < 0.001）。感染烟曲霉的患者（2537±398.5 HU）和未感染烟曲霉的患者（2544.3±460.6 HU）的根充材料显示出几乎相同的CT值。感染烟曲霉患者的根充材料密度与不透X线结石的密度处于同一水平。根据CT检查，发现根充材料与烟曲霉感染之间存在直接联系。因此，对于有不透X线结石的患者，计算机断层扫描检查有助于确定鼻窦感染的类型。
