Output: no

Input: Consider Input: Question: Does melatonin prevent radiation-induced oxidative stress and periodontal tissue breakdown in irradiated rats with experimental periodontitis?
Answer: It was found that radiotherapy increased oxidative stress, the periodontal attachment level and alveolar bone loss, and protective melatonin administration significantly reduced the oxidative parameters and prevented periodontal damage in irradiated rats with experimental periodontitis. Further research is needed regarding the use of systemic melatonin administration before radiation therapy.
Output: yes
