3. Retentive point
4. Retentive pin

Conservative Dentistry Answer: 1

Explanation:�In modified Class III cavity restorations,
particularly those involving composite materials, retention is often achieved
through acid etching. This process creates micro-retentive features on the
enamel and dentin surfaces, allowing the bonding agent to penetrate and create a
strong bond with the tooth structure. While retentive grooves, points, and pins
can also be used, acid etching is a fundamental technique that enhances
retention in adhesive dentistry.
