Investigation of the relationship between periodontal disease and serum and gingival crevicular fluid sclerostin and tumor necrosis factor-α levels in women with postmenopausal osteoporosis

Aim: In this study, it has aimed to reveal the relationship between postmenopausal osteoporosis and periodontitis by comparing inflammatory (TNF-α) and bone destruction biomarker (sclerostin) levels in serum and GCF and clinical periodontal parameters in postmenopausal women with decreased BMD. Materials and Methods: A total of 80 postmenopausal female have included in our study. Patients have divided into 4 groups according to radiological and clinical examination results as control (Group K), periodontitis (Group P), osteoporosis (Group O) and osteoporosis-periodontitis (Group OP). Clinically, PI, GI, BI, PPD and CAL have measured. TNF-α and sclerostin levels have measured by ELISA method in serum and DOS samples. In addition, L1-L4, femoral total and femoral neck BMD values have determined by DXA method. For statistical analyses, Shapiro Wilk test, Mann Whitney U test, Anova test, Kruskal Wallis test, Post Hoc Bonferroni test, Pearson Chi-Square test, Fisher's Exact test, Pearson and Spearman correlation have used. Results: Serum sclerostin level of Group OP and Group P and GCF sclerostin level of Group OP, Group P and Group O have higher than Group K (p<0.05). A positive correlation has found between serum sclerostin level and serum TNF-α (p=0.013, r=0.278) with GCF TNF-α (p=0.001, r=0.356) levels (p<0.05). A positive correlation has found between GCF TNF-α (p=0.002, r=0.334) and GCF sclerostin level (p<0.05). Conclusion: The increased level of sclerostin in serum and DOS in osteoporosis patients may increase the severity of periodontal disease by creating a destructive effect on the periodontium; It is also thought that it can be used as a biomarker to elucidate the common mechanism in the relationship between postmenopausal osteoporosis and periodontitis.
