“AS RECEIVED” ELASTOMERIC CHAINS: ARE THEY CONTAMINATED?

YG Reddy, Deoashish Gupta

Abstract


BACKGROUND

Generally, the elastomeric chain is cut off from the spool and embedded in the oral cavity without being submitted to any procedure of sterilization

AIM & OBJECTIVE

To evaluate elastomeric chains from different manufacturers to verify the presence of pathogenic microorganisms at the moment of unpacking.

MATERIAL & METHOD

Elastomeric chains from D-tech orthodontics co., G&H orthodontics co. and American orthodontics co.were placed in tubes containing Nutrient broth medium, Robertson’s cooked meat broth medium and Nutrient broth medium. The samples were incubated at incubated at 37 0C for 5 days for culture of bacterial colonies. All the samples sub cultured on Sabouraud’s dextrose agar were incubated at 25 0C for 3 weeks for culture of fungal colonies

RESULT

No microorganism growth was detected after all incubation periods. No inhibition zones were identified surrounding the elastomeric chain.

CONCLUSION

The Elastomeric chains showed absence of microbial contamination on their surface in the present study.
