Definition: A cavity liner is a dental material used to protect the pulp from irritants and bacteria during the restorative process of filling a cavity, providing a protective barrier between the restoration material and the tooth’s pulp.
Variations: There are different types of cavity liners, such as calcium hydroxide liners or resin-based liners, each with specific applications based on the clinical scenario and patient needs.
Common Uses: Cavity liners are commonly used in deep cavities or cases where the cavity is close to the pulp, to prevent sensitivity and potential pulp damage during the placement of the filling material.
Procedure: Cavity liners are applied in a thin layer directly on the dentin surface before the placement of the restorative material, ensuring proper isolation and protection of the pulp. The application may vary depending on the specific liner type used.
Risks: Improper placement of a cavity liner can lead to issues like pulp irritation, pulp necrosis, or incomplete sealing, emphasizing the importance of precise application and proper technique.
Maintenance Requirements: After the application of a cavity liner, it is essential to follow up with the correct restorative procedure and provide adequate post-operative care to ensure the longevity and success of the restoration.
Associated Terms: Cavity liners are often used in conjunction with dental bonding agents, etchants, and restorative materials to create a durable and long-lasting restoration.
Recent Developments: Recent advancements in cavity liner technology focus on biocompatibility, longevity, and ease of application, enhancing the overall success rate of restorations in dental practice.
Regulations: Dental professionals must adhere to specific guidelines and regulations set forth by regulatory bodies to ensure the safe and effective use of cavity liners in clinical practice.
