Background: Considering the mechanical properties essential for effective root canal cleaning, this study aimed to compare the effectiveness of pediatric rotary and manual files in reducing Enterococcus faecalis bacteria and postoperative pain in root canals of necrotic primary molars.
Materials and Methods: In this clinical trial, 36 necrotic second primary mandibular molars of 6 to 8 years old children were selected. First, x-rays were performed then children were divided into two groups. In first group (A) canals were cleaned using Universal Protaper rotary files and manual endodontic files in the second group(B). For bacterial evaluation sampling was carried out using paper points sizes 15 and 20, before and after cleaning the canals. The samples were then transferred to the laboratory. I n the second session a questionnaire was filled by parents concerning postoperative pain. A week after patients was recalled for repairing the tooth crown with a stainless steel crown. Data were analyzed using Wilcoxon and Mann-Whitney tests.(α=0.05)
Results: The pain level in group B was significantly higher than group A (p<0.001). Enterococcus faecalis colony count was significantly lower in group A after treatment (p<0.001).
Conclusion: Rotary files showed a better ability to remove Enterococcus faecalis bacteria in necrotic primary molars. Also, children were more satisfied with rotary files because of the reduction of postoperative pain.
