Summary

This study followed 190 adults who had or were about to have a stem cell transplant from a donor. Researchers tracked changes in the mouth, like dryness or sores, to learn more about chronic graft-versus-host disease (cGVHD). Participants provided saliva, mouth swabs, and had dental exams over three years. The goal was to better understand how cGVHD develops in the mouth, not to test a new treatment.
