Eficacia del hipoclorito de sodio usando técnica convencional vs ultrasónica pasiva en la desinfección del conducto radicular. Revisión de literatura.

Abstract

NTRODUCTION: NaOCl is an antimicrobial agent used as an irrigant for root canals of organic tissue. Different techniques are used for the activation of the irrigating agent; the manual method, using syringes of various volumes and needles with various gauges; the ultrasonic method, by means of specialized tips, generates acoustic movement that infiltrates the irrigant, operates athigh frequency, but at low amplitude. OBJECTIVE: To compare the efficacy of root removal by sodium hypochlorite using the conventional technique vs. passive ultrasonic during endodontic therapy. MATERIALS AND METHODS: A descriptive and analytical crosssectional study was presented; literature review through various search engines, 30 articles were used as a sample following the inclusion and exclusion criteria. RESULTS: The analysis of the scientific literature was separated by variables: endodontic irrigation materials, endodontic irrigation time, endodontic disinfection technique, sodium hypochlorite irrigation volume, sodium hypochlorite irrigation concentration. Information was collected from each variable of the scientific articles to obtain the results. CONCLUSION: The passive ultrasonic technique for irrigation does not have a cutting effect on the canal walls and transmits energy to the irrigating solution. Irrigation lasting less than 5 minutes and a concentration of 2.5% NaOCl with a volume of 5ml per root canal with 2 or 3 changes of the irrigating solution has proven to be the most effective.
