O uso do ultrassom para desinfecção dos canais radiculares: uma revisão de literatura

Abstract

Passive ultrasonic irrigation (IUP) is the most widely used method of irrigation with the use of ultrasound in endodontics, promoting the activation of irrigators within the root canal and increasing the temperature of the irrigation substance. This technique increases the capacity of tissue dissolution, which reinforces the effect of cleaning and disinfection, demonstrating a superior action compared to the conventional technique. Therefore, much has been discussed about the advantages that IUP has been presenting, improving the removal of organic tissue, bacteria and dentinal remains from the interior of the root canal. Thus, the purpose of this study is to analyze the effectiveness of ultrasonic activation of irrigation solutions in cleaning and disinfecting the root canal, through a review of descriptive literature, conducted through an electronic search of journals published between the years 2014 and 2019 in the MEDLINE, SCIELO, LILACS databases. IUP consists of a complementary approach to syringe irrigation (conventional technique) and root canal disinfection. Its main objective is to enhance the action of the irrigation solution in the effective cleaning of the conduit. It is concluded that the use of activated ultrasound and associated with irrigation solutions are allies in endodontic treatments and have proven effective in an indispensable step in endodontic therapy which is the biomechanical preparation, disinfecting and avoiding periapical re-infections.
