Table 4. Comparison of the morphometric parameters in patients with Sjögren’s syndrome with and without xerostomia-related dental disease.
| Parameter | Xerostomia-related dental disease | No xerostomia-related dental disease | p value |
|---|---|---|---|
| Depth-integrated LMSG surface filling factor (IFF) | 0.14 (0.09-0.15) | 0.05 (0.04-0.06) | 0.03 |
| LMSG surface filling factor at z1 (FF1) | 0.05 (0.04-0.10) | 0.01 (0.00-0.03) | 0.02 |
| LMSGs’ surface density at z2 (ρ2), cm−2 | 4.06 (3.19-4.57) | 3.04 (2.66-3.09) | 0.02 |
| Average single LMSG area A in tissue sample, mm2 | 3.13 (3.02-3.63) | 2.26 (1.75-2.89) | 0.01 |
| Epithelium heterogeneity SDep | 12 (12-13) | 10 (9-11) | 0.03 |
| Glandular tissue heterogeneity SDgl | 16 (15-16) | 13 (12-13) | 0.05 |
*The data are presented as median (interquartile range). Tissue depths: z1 = 500 µm, z2 = 650 µm, z3 = 800 µm. LMSG – labial minor salivary gland, SD – standard deviation.
