Scientists created a new type of artificial saliva that can help protect teeth from acid and decay. This is especially important for patients with head and neck cancer who often experience dry mouth after radiation therapy.

Patients with head and neck cancer often undergo radiotherapy near the mouth, which can damage salivary glands and reduce saliva production. Without enough saliva, bacteria can grow and cause serious dental problems. Researchers at the Bauru School of Dentistry in Brazil created a new type of artificial saliva using a lab-modified sugarcane protein called CANECPI-5. This artificial saliva was delivered as a mouthwash and formed a protective layer over teeth, defending enamel from acids found in beverages like juice and alcohol, as well as acids from the stomach.

The researchers tested the artificial saliva by applying it to small pieces of animal teeth once a day for one minute. The results showed that CANECPI-5 works best when combined with fluoride and xylitol. In testing, the artificial saliva reduced bacterial activity and slowed tooth demineralization, making teeth more resistant to cavities.

This development is especially important because there is currently no dedicated product available to treat the severe cavities that often occur after radiation therapy for head and neck cancer.

Why It Matters

This discovery matters in India because it can help patients with head and neck cancer who are treated at hospitals like Tata Memorial Centre or AIIMS. It also highlights the importance of oral health, which is often overlooked despite its impact on overall well-being.
