Cention N: A Review

The aim of a dental restorative material is to simulate the biological, functional and esthetic properties of healthy tooth structure. Silver amalgam which has a long record of clinical success is gradually phasing out because of its disadvantages including its metallic grey colour, lack of adhesion and mainly the controversial debate on its safety. Resin based composite have also become a popular alternative to amalgam in posterior teeth however they are also perceived as expensive, time consuming, technique sensitive and exhibit failure related to excessive wear, polymerization shrinkage and microleakage. Cention N is a recently introduced, tooth coloured, direct filling material for posterior load bearing restoration. It is analkasiterestorative which utilizes alkaline filler which is capable of releasing acid-neutralizing ions and an isofiller which reduces polymerization shrinkage. It is a self-curing filling material with optional light curing. Cention N is a cost efficient substitute of amalgam for posterior load bearing restoration.
