Evaluation of Antimicrobial Efficacy of Etidronic Acid against in Primary Teeth: An Study.

Background: In pulpectomy, to remove the inflamed or diseased pulp tissues and smear layer, the root canal is disinfected with mechanical instrumentation and copious irrigation.

Aim: The purpose of this present study is to evaluate the antibacterial efficacy of etidronic acid as an irrigant in primary teeth.

Materials And Methods: A total of 60 necrotic primary teeth in children aged 3-8 years were included. Of these, 30 were irrigated with 2% chlorhexidine (CHX) gluconate (group I) and 30 with 9% etidronic acid (group II). Two microbiological samples were collected with sterile paper points from the canal in both groups during the pulpectomy process-first after access opening and before the first irrigation (S1), and second after instrumentation and final irrigation, before filling (S2). The presence of was determined using colony-forming units per milliliter (CFU/mL) in all samples (S1 and S2).

Results: After analyzing the samples before and after irrigation in groups I and II, there was a statistically significant reduction in CFU/mL ( < 0.05). Group II had a statistically significant advantage when the two groups were compared after irrigation.

Conclusion: As a result, etidronic acid can be recommended as a pulpectomy irrigating solution for necrotic primary teeth.
