What is A 40 year old male patient complains of decayed tooth. Patient gives history of cavity preparation and restoration with mixture of spherical alloy particles and mercury done with 26. Intra-oral examination reveals proximal caries with 26. Which of the following is not the property of alloy particles used to restore the tooth in this patient?​ and explain in detail?
It was demonstrated that​ by spherodizing the alloy particles, the particles​ packed more efficiently and required​ much less mercury to make a practical mixture. Spherical particles also increased the fluidity of the mixture by​ presenting less resistance to particle sliding. Using some​ or all spherical alloy particles, it is possible to reduce the​ mercury portion of the mixture to less than 50% by​ weight.​
