RESTORATION FEATURES

 Ideal amount of dentine between amalgam & pulp – 2mm
 Amalgam average life span (when pt asks) ー15- 20 years or 2 decades
 For amalgam Restoration of weakened cusp you should reduce cusp by 2mm on a flat base for more resistance.
 Amalgam shows decreased microleakage with age
 It is least technique sensitive of all the current cases
 The base cement for amalgam should have – high modulus of elasticity
 Scale to measure marginal detoriation / leakage / fracture in amalgam – Mahler scale
