Resumo

Objective: The aim of this study was to investigate the development of microorganisms in extracted teeth that did not receive any prior sterilizing treatment. Study design: Thirty human permanent teeth were transferred to individual glass vials in which aliquots of sterile saline solution were added. After sonication, 10 microliters of each suspension were dispensed on six different culture media surfaces. Post-incubation grown colonies were counted. Results: High numbers of colony forming unities (CFU) were detected in Letheen Agar, MacConkey Agar, and Xilose Lisine Deoxycholate Agar, demonstrating the high dental contamination by aerobic Gram-negative rods. Yeasts also were found in great number occurring in the teeth. Pathogenic bacteria as staphylococci and pseudomonades did not appear in Mannitol Salt Agar and Cetrimide Agar, respectively. Conclusions: Based on these results, we propose that contamination could be due to either an excess of manipulation after the extractions, or to the storage in inappropriate sanitary conditions.
