The study was conducted in intensive care units and included patients diagnosed with COPD. The study was conducted with a total of 60 COPD patients, 30 in the intervention group and 30 in the control group. Individuals in the intervention group were given an oral care protocol containing propolis for 15 days, in addition to the clinic's standard oral care protocol. The control group continued to receive standard oral care. Oral mucosa was assessed on days 1, 7 and 15 using the World Health Organization (WHO) Oral Mucositis Scoring Index and the Oral Assessment Guide (Oral Mucosa Score, OMS).
