Some manufacturers of dental alloys
permit the use of once melted alloys but not less than the 50% addition of the brand new material.
These findings suggest that exposure to Cd released from dental alloy
restorations may influence many aspects of mineralized hard tissue of teeth and their immediate surrounding periodontal tissues.
The standards for assessing the mechanical properties of dental alloys
 place emphasis on E, [A.sub.t], and [R.sub.P0.2] of the alloys.
Further it has been reported that water, oxygen, chloride, sulphur corrodes various metal present in the dental alloys
. Corrosion can severely limit the fatigue life and ultimate strength of the material leading to mechanical failure of the dental materials .

Our results are clinically significant because demonstrate that the individually oral conditions, the specific parameters and composition of the oral fluids are responsible for the corrosion behaviour and the biocompatibility of the precious and non-precious dental alloys
. The selection of the dental alloy
should be based on the salivary pH evaluation of each patient.

Metals or dental alloys
can cause inflammatory reactions due to toxic or irritant effect.
(5,6) It is a preferred metal for fabricating the prosthetic superstructure of an implant abutment since, use of different dental alloys
for the superstructure of the implants leads to detectable galvanic corrosion.
These dental alloys
need for the disinfection in order to prevent the transmission of infectious disease in dentistry.8 Most popular method is Functional Water because of its outstanding virucidal and bactericidal activities and its less adverse effects on environment and the biological tissues.89 Functional water is defined as an aqueous solution thatacquires useful functions and has reproducibility with artificialprocessing; those where scientific basis makes clear in regard toprocessing and function.10 This includes electrical magneticelec tromagnetic (infrared microwave or etc.) ultrasound andvortex implosion.
Titanium and its alloys provide strength, rigidity, and ductility, similar to those of other dental alloys
. Whereas, titanium and its alloy have excellent biocompatibility, low density, low thermal conductibility, good mechanical properties and greater corrosion resistance in saline and acidic environments.
