Among the 67 studies in Osteoporosis with a site in Turkey, from their registry updates:
This study examines saliva samples from patients with osteoporosis. The levels of cytokines and Matrix Metalloproteinase-8 (MMP-8) enzyme in saliva will be measured. Additionally, the dental caries status of participants will be evaluated. The aim of this study is to understand the relationship between osteoporosis and oral health. Only saliva samples will be collected from participants; no treatment or medication will be administered.
The criteria were revised on the registry on Nov 3, 2026. See what changed
Patients diagnosed with osteoporosis who applied to the outpatient clinic. Saliva samples and dental caries status will be evaluated. Participants will be selected according to inclusion and exclusion criteria.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
