Question

Quizplus · Accepted Answer

A low-strength base or liner is placed in a thin layer on the walls and floor of the cavity preparation to provide thermal insulation and protection of the pulp from chemical irritation, as well as to enhance the retention of the final restoration. Luting agents are used for cementation of restorations, varnish is used to protect tooth surfaces from decay, and high-strength bases are used when additional support is needed for large restorations or when significant portions of tooth structure are missing.
