Table 1.

Mean anti-S100-stained Langerhans cell (LC) number in the lining epithelium and 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	P-value
Severe inflammation (n = 9)	21.0 ± 7.0	11.1 ± 6.5	0.007
aP-value	<0.001	<0.001
bP-value	<0.001	<0.001
Mild/moderate inflammation (n = 33)	8.1 ± 2.0	4.5 ± 2.3	<0.001
aP-value	<0.001	<0.001
No inflammation (n = 80)	0.6 ± 0.6	0.7 ± 0.6	0.879
