- 1give reason : the oral enviroment is very conductive to formation of corrosion products ?as it is moist and subjected to fluxion in temp. and PH .
- 2eggs can corrode some restoratins ?they contain sulfur that can corrode silver , copper,murcury and similar metals which can be found in dental alloys and amalgam .
- 3storage of amalgam can affect the process of amalgamation ?the oxidiation of amalgam containing eutictic phase of AG_CU forms a layer that prevents good wetting of mercury and affecting amalgamation process .
- 4solder joints between dental alloys may corrodebecause of the difference in composition between solder and alloy thus having different electrode [otentials that may lead to local galvanic corrosion .
