Clinical Trial Summary

Psoriasis is a chronic inflammatory disease with a multi-factorial etiology which affects the epidermis and dermis. It affects around 1-3% of the general population and its most frequent form is plaque psoriasis (around 80-90% of the overall psoriasis cases). Psoriasis severity and extension are usually measured through 2 scores: Psoriasis Area Severity Index (PASI) and Body Surface Area (BSA). Periodontitis is a chronic inflammatory disease mediated by the biofilm and with a multi-factorial etiology. Its manifestation entails the destruction of the periodontal tissues surrounding the teeth; the final stage of disease is characterised by tooth loss. Periodontitis severity and extension are usually evaluated through surrogate variables such as: BoP (Bleeding on Probing), PPD (Probing Pocket Depth) e REC (Recession). Both diseases present overlapping genetic and pathophysiologic features, as well as common risk factors (e.g. genetic polymorphisms, smoking habit, obesity, diabetes etc.).

miRNAs are small non-coding molecules involved in the regulation of various biologic processes thanks to their interaction with mRNAs. Active inflammatory processes either in the oral cavity or at a systemic level tend to alter the concentration of salivary miRNAs. No study so far has ever profiled the levels of specific salivary miRNAs in patients with psoriasis and periodontitis.

Some case-control studies highlighted a higher prevalence of periodontitis in patients with psoriasis when compared to healthy controls. Nonetheless, epidemiological data regarding periodontitis prevalence in patients with psoriasis are lacking; moreover, few data are available regarding the relationship between the severity of psoriasis and the severity of periodontitis, together with the effect of common risk factors (e.g. diet, obesity, physical activity, sleep quality etc.).

• Plaque Psoriasis
• Psoriasis

Intervention

Diagnostic Test:
• Full periodontal chart
A full periodontal chart will be carried out including all biometric periodontal variables: Probing Pocket Depth (PPD), Bleeding on Probing (BoP), presence of Plaque, recession (REC), Full Mouth Plaque Score (FMPS), Full Mouth Bleeding Score (FMBS), presence of furcation and mobility. Periodontal status, as assessed by the periodontal chart, will be evaluated following the New Classification of Periodontal and Peri implant diseases.

Other:
• Saliva sampling
Saliva samples for miRNAs detection will be taken before starting the visit.
