In order to facilitate the rapid penetration of resin, the tooth surface should be properly prepared. This can be achieved by removing any debris, plaque, or calculus from the tooth surface using mechanical or chemical methods. Cleaning the tooth surface allows for better bonding between the resin and the tooth structure.

Using a dental bonding agent can also aid in the rapid penetration of resin into the tooth structure. These bonding agents contain various chemicals that help to create a strong bond between the tooth and the resin material. Applying the bonding agent onto the prepared tooth surface before applying the resin can enhance its penetration.

Applying a thin layer of acid etchant to the tooth surface can increase the micromechanical retention of resin material. The acid etchant creates small irregularities on the tooth surface, known as microporosities, which allow the resin to interlock with the tooth structure more effectively. This enables better penetration of the resin into the tooth, resulting in improved bonding.

Using light-curing techniques can also promote the rapid penetration of resin. Light-curing involves using a dental curing light to activate photoinitiators in the resin, causing it to harden and bond to the tooth structure. This method helps to ensure that the resin material fully penetrates into the tooth, creating a strong and durable bond.

Applying a bonding agent or adhesive primer specifically designed for resin penetration can further enhance the bonding process. These products contain special ingredients that improve the resin's ability to infiltrate the tooth structure effectively. Using a compatible bonding agent or primer in combination with the resin material can significantly improve its penetration and bonding strength.
