Psoriasis Patients Suffer From Worse Periodontal Status—A Meta-Analysis

Abstract

Background and Objective: Patients with psoriasis have a significantly elevated risk of periodontitis compared with the nonpsoriasis controls. However, the data regarding the difference in the periodontal health status of the psoriasis patients and the nonpsoriasis controls are limited and inconsistent; hence, a specialized meta-analysis that quantitatively compared the periodontal status between the psoriasis and nonpsoriasis subjects by evaluating the related clinical periodontal indexes was needed. The aim of this meta-analysis was to quantitatively evaluate whether the periodontal status of psoriasis patients is worse than that of nonpsoriasis subjects.Methods: We searched PubMed and EMBASE for all eligible studies that compared the periodontal status between psoriasis patients and nonpsoriasis subjects. The studies were screened based on pre-established inclusion criteria. After extracting the available periodontal indexes from the included studies, the weighted mean difference (WMD) with 95% confidence intervals (CIs) was calculated by pooling the mean and standard deviations (SD) of each index.Results: In total, 8 studies, including 812 psoriasis patients and 772 nonpsoriasis subjects, were included in our meta-analysis, and the publication dates ranged from 2013 to 2019; eight periodontal indexes were analyzed. The WMD (95% CIs) for each index were: bleeding on probing (%), 9.188 (4.046–14.330, P < 0.001); probing depth (mm), 0.524 (0.183–0.865, P = 0.003); clinical attachment loss (mm), 0.408 (0.051–0.765, P = 0.025); plaque index, 0.186 (−0.170 to 0.543, P = 0.306); gingival index, 0.458 (−0.413 to 1.328, P = 0.303), remaining teeth, −1.709 (−2.106 to −1.312, P < 0.001); missing teeth, 1.130 (0.275–1.985, P = 0.010); the level of alveolar bone loss (mm), 0.400 (0.102–0.698, P = 0.008).Conclusion: In summary, our meta-analysis revealed that psoriasis patients suffer from worse periodontal health than do nonpsoriasis subjects, mainly characterized by worse gingival inflammation, more alveolar bone loss, fewer remaining teeth and more missing teeth. Considering the limitations of this meta-analysis, more high-quality and well-designed studies are needed to validate our conclusions in the future.

Smoking and Periodontitis Can Play a Synergistic Role in the Development of Psoriasis: A Nationwide Cohort Study

“…Second, periodontitis and psoriasis share common risk factors and comorbidities, and it is thought that this may serve as a link between the two diseases [30, 31]. Several reports suggest that patients with periodontitis exhibit an increased risks of metabolic syndrome and CVD, which is a common comorbidity in psoriasis [8, 13, 30, 32, 33]. Chronic periodontitis has been suggested to be a distant source of inflammatory byproducts associated with insulin resistance and obesity [13, 34, 35].…”

“…Previous systematic reviews have studied the relationship between periodontitis and psoriasis (Qiao et al, 2019;Ungprasert et al, 2017).…”

Identification of venular capillary remodelling: a possible link to the development of periodontitis?

“…Identical venous capillary changes occur in patients with Sjögren syndrome [ 32 ]. This is interesting as there is a significant association linking periodontitis, cardiovascular disease, Sjögren syndrome, rheumatoid arthritis, and psoriasis; these all have an inflammatory element that is associated with microvascular proliferation, and a significant increase in venous capillaries is a feature of the disease process in all of these conditions [ 33 34 35 36 ].…”
