Sugarcane protein mouthwash helps protect oral health during head and neck cancer treatment

An artificial saliva in the form of a mouthwash, produced with the CANECPI-5 protein extracted from sugarcane and modified in a laboratory, can aid in treating teeth in patients with head and neck cancer. In these cases, radiotherapy very close to the mouth can destroy salivary glands and compromise saliva production, which is essential for controlling bacteria and disease.
