In Dr. Zhugang Zheng Dental Office, we have traditionally used resin modified glass ionomer (RMGI) liner/bases for deep cavities and composite procedures. By their nature, RMGI liners are typically fluid materials that can adapt more readily to the internal aspects of a cavity preparation. In the past three years, our practice has become accustomed to using RMGI liner/base products with almost every procedure. As a dental assistant, it's crucial to know when and why RMGI liner/base products should be used as well as what your role is in placing the product.
Dr. Zhugang Zheng Dental Office uses a RMGI liner/base on practically every procedure because of the added benefits for patients. In addition to providing a foundation for the restoration, RMGI liner/bases provide extra protection for your patients by preventing microleakage under the restoration, inhibiting bacterial growth, reducing sensitivity, and releasing fluoride into the tooth. Additionally, they're very easy to place and offer versatile protection for many types of restorations.
