Salivary changes and dental caries as potential oral markers of autoimmune salivary gland dysfunction in primary Sjögren's syndrome

Table 2 Oral findings in the patients with primary Sjögren's syndrome (pSS) and the healthy controls. Results are given as number of patients or scores (yes/no) and in medians (ranges).

	pSS (n = 20)	Healthy controls (n = 20)	P-value
No. of teeth	22 (6–28)	28 (0–28)	0.011^a
DMFS*	83.0 (25–140)	43.0 (10–140)	0.001^a
Distribution of D/M/FS	23/745/1020	14/305/662	<0.001^b
Subjects with dentures (yes/no)	4/16	7/13	0.480^c
Distribution of PI (no. of 0/1/2/3 scores)	245/179/54/2	244/152/60/0	0.272^b
Distribution of GI (no. of 0/1/2/3 scores)	346/116/16/2	330/95/31/0	0.034^b
Probing pocket depth (PPD, mm)	2 (1–4)	2 (1–3)	0.523^a

*D/M/FS, decayed, missed, filled surfaces; PI, plaque index; GI, gingival index. P-values obtained by Wilcoxon rank sum test (a), Chi²- test (b), and Fisher exact test (c).
