Herein, what does an insulating base provide for the restoration of a tooth?

its placed in a deep cavity preparation to protect the tooth from thermal shock. It occurs when sudden temperature changes occur.

Subsequently, question is, where is a dental liner placed? A dental liner is a material that is usually placed in a thin layer over exposed dentine within a cavity preparation. Its functions are dentinal sealing, pulpal protection, thermal insulation and stimulation of the formation of irregular secondary (tertiary) dentine.

Simply so, what effect does eugenol have on the pulp?

Eugenol-containing dental materials are frequently used in clinical dentistry. When zinc oxide-eugenol (ZOE) is applied to a dentinal cavity, small quantities of eugenol diffuse through the dentin to the pulp. Low concentrations of eugenol exert anti-inflammatory and local anesthetic effects on the dental pulp.

Why would a dentist place a liner?

Dental cavity liners have historically been used to protect the pulp from the toxic effects of some dental restorative materials and to prevent the pain of thermal conductivity by placing an insulating layer between restorative material and the remaining tooth structure.
