Hyaluronic Acid in the Treatment of Hyposalivation

The goal of this clinical trial is to learn if drug containing non-crosslinked hyaluronic acid and amino acids solution (Sunecos-200) works to treat hyposalivation in adults. It will also learn about the safety of drug Sunecos-200. The main questions it aims to answer are: * Does Sunecos-200 improve the saliva secretion and improve a life comfort? * What medical problems do participants have when taking Sunecos-200? Researchers will compare drug containing non-crosslinked hyaluronic acid and amino acids solution (Sunecos-200) to a control group (without intervention) to see if drug Sunecos-200 works to treat hyposalivation. Participants will: * Take drug Sunecos-200 by into oral mucosa injection or nothing every two weeks for 4 times. * Visit the clinic once every 2 weeks for checkups and tests * Keep a diary of their symptoms after injection and fill out a primary and final questionary.

Repeated Mesenchymal Stem Cell Therapy for Radiation-Induced Hyposalivation and Xerostomia in Head and Neck Cancer Survivors

Dry mouth leads to debilitating symptoms 24/7. The two primary causes for dry mouth are Sjögrens disease and after radiotherapy of a head and neck cancer. Former clinical trials have investigated mesenchymal stem cell treatment for dry mouth with promising results. However, few of the participants evolved normal salivary flow rate. Therefore, in this randomized clinical trial, two treatments of mesenchymal stem cells are administered, 4 months apart. This has not been done before. The hypothesis is that two treatments of mesenchymal stem cells results in a higher salivary flow rate and ameliorate symptoms from dry mouth.
