Table 2.
Comparisons of mean anti-S100-stained Langerhans cell (LC) count with mean anti-CD1a-stained LC count in the lining epithelium or in the subepithelial connective tissue of 80 dentigerous cysts.
| Inflammation in focal fibrous cystic wall site | Mean LC count ± SD (cells/high-power field) |
|
|---|---|---|
| Lining epithelium | Subepithelial connective tissue | |
| Severe inflammation (n = 9) | ||
| Anti-CD1a stain | 18.9 ± 7.0 | 6.7 ± 5.8 |
| Anti-S100 stain | 21.0 ± 7.0 | 11.1 ± 6.5 |
| aP-value | 0.540 | 0.149 |
| Mild/moderate inflammation (n = 33) | ||
| Anti-CD1a stain | 6.8 ± 1.8 | 2.4 ± 2.0 |
| Anti-S100 stain | 8.1 ± 2.0 | 4.5 ± 2.3 |
| aP-value | 0.010 | <0.001 |
| No inflammation (n = 80) | ||
| Anti-CD1a stain | 0.5 ± 0.5 | 0.2 ± 0.3 |
| Anti-S100 stain | 0.6 ± 0.6 | 0.7 ± 0.6 |
