Background: Infection control in dentistry is becoming more important , new products and methods are being developed to prevent cross- contamination between dental patients and dental personal via impression ,model ,record base and appliance however ,there is growing concern on dental cast disinfection ,incorporation of disinfection solution in dental stone could provide an effective method to disinfect stone cast.
Methods: this project was under taken in an attempts to study the effect of the disinfection solutions on the compressive strength of dental stone .accordingly , three type of disinfectant solution were incorporated into one brand of dental stone.(60) samples made from dental stone materials divided into( 4) group first group was control mixing dental stone with distil water; the second group was mixed dental stone with(Corsodyl) mouth wash glaxo smith line group of companies united kingdom groupes mixing dental stone with (chlorhexidine digluconate 0.2%), the third group that mixed dental stone with (Zak DNV Syria) mouth wash (chlorhexidine digluconate 0.12%), the foure group that (AL-Mansor) mouth wash almansor company(chlorhexidine digluconate 0.2%).
The properties evaluated was compressive strength the results were compared with those obtained from (Hi-Stone) which was used as control.
Results: the results revealed that incorporation of disinfection solution in stone mixture improved compressive strength of dental stone.
Conclusions: In conclusion, dental stone containing chlorhexidine diglucanate (0.2% Almansor company Iraq) provide to be superior among the other tested groups
