What type of cavity is typically restored with glass ionomer cement?

• A. Larger Class I cavities
• B. Class V cavities
• C. Deep Class II cavities
• D. Class III cavities

Answer: (B)

Glass ionomer cement is particularly suitable for restoring Class V cavities, which are located at the gingival third of the tooth and may be affected by cervical erosion or abrasion. The unique properties of glass ionomer cement, such as its ability to chemically bond to both enamel and dentin, make it particularly advantageous for these types of restorations. Moreover, glass ionomer releases fluoride, which helps in providing additional prevention against caries at the margins of the restoration, a crucial aspect given that Class V cavities often occur in areas susceptible to decay. While the other types of cavities mentioned can be restored with different materials like composite resin or amalgam, Class V cavities stand out as the ideal candidates for glass ionomer cement due to the material’s efficacy in bond strength and fluoride release in these areas. This makes it a preferred choice in cases where aesthetics are less of a concern and where managing sensitivity and enhancing protection against further carious activity are priorities.
