Histological damage score

	C (n=9)	P (n=9)	P+Cr (n=9)	P
Interstitial inflammation	0 (0-0)^a	2 (2-3)^b	1 (0-2)^c	<0,001
Tubular epithelium injury	0 (0-1)^a	2 (1-3)^b	1 (0-1)^c	<0,001
Tubular basement membrane injury	0 (0-0)^a	2 (1-2)^b	0 (0-1)^a	<0,001
Total damage score	0 (0-1)^a	7 (6-9)^b	2 (1-3)^c	<0,001

Groups: C: control; P: periodontitis; P-Cr: periodontitis + crocin. In each row, significant difference (P<0.001) is denoted with different superscripts
