Pulpotomy therapy and contamination of handpieces among children attending the dental hospital

الملخص EN

Background : The purpose of this study to determine the contamination with oral flora when used low speed handpieces for pulpotomy therapy on primary teeth.

Material and methods : Children aged 7 – 9 years attending the dental clinic were examined for 24 pulpotomies on primary teeth from 24 subjects then analyzed microbiologically to detect the extent of bacterial contamination from patients saliva by using brain – heart infusion broth, and blood agar.

Results : Microbial analysis indicated aerobic and anaerobic bacterial contamination at all 3 – sites from all 24 handpieces 100% bactrerial and blood contamination .The 3 – sites didn’t have significantly different levels (cfu / ml) at P < 0.001.

Conclusion : These data suggest that the inertial surface of low speed handpieces can become microbially contaminated during use with pulpotomies teeth unless properly sterilized between patients.
