ABSTRACT
<p><b>OBJECTIVE</b>This study aimed to investigate the expression and correlation of secreted frizzled-related protein 1 (SFRP1) and β-catenin in gingival tissues of patients with chronic periodontitis (CP). The role of the classical Wnt/β-catenin signaling pathway in the development of periodontitis was also explored.</p><p><b>METHODS</b>Twenty-eight patients with CP (CP group) were enrolled in this study. Among them, 16 cases were moderate CP, and 12 demonstrated severe CP. Twelve healthy cases comprised the controls (normal group). Gingival tissue was collected, and the probing depth, bleeding index, and clinical attachment loss were recorded. The expression levels of SFRP1 and β-catenin were detected by immunohistochemistry, and staining intensity was evaluated by double scoring method. SPSS 19.0 was used for statistical analysis.</p><p><b>RESULTS</b>The staining strength scores of SFRP1 and β-catenin were 2.16±0.65 and 1.12±0.51 in the normal group, 3.57±0.45 and 2.36±0.49 in the CP group, 3.61±0.40 and 2.30±0.44 in the moderate CP group, and 3.52±0.52 and 2.45±0.55 in the severe CP group, respectively. The expression of SFRP1 and β-catenin in the CP group was higher than that in the normal group (P<0.01). A significant difference was noted between the normal group and the moderate and severe CP groups (P<0.01) but none between the moderate and severe CP groups (P>0.05). A positive correlation was found between the expression of SFRP1 and β-catenin (r=0.657, P<0.01). The expression levels of β-catenin and SFRP1 were related to periodontal indexes. The correlation between the expression of SFRP1 and probing depth was most significant (r=0.723, P<0.01), as well as that between β-catenin and bleeding index (r=0.697, P<0.01).</p><p><b>CONCLUSIONS</b>Patients with CP exhibit elevated expression of SFRP1 and β-catenin in gingival tissues, and this event is related to the degree of periodontal destruction. Abnormal expression of SFRP1 and β-catenin may promote the development of periodontitis.</p>
