Abstract

ALCANTARA DUFEU, Raúl; PENA FARFAL, Carlos  and  ALVAREZ MUNOZ, Mónica. Retrieval of Fractured Files Based on Electrochemical Dissolution. Int. J. Odontostomat. [online]. 2013, vol.7, n.3, pp.475-481. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2013000300022.

The purpose of this study was to investigate whether the Electrochemical Dissolution (DE) facilitates the retrieval of fractured files, from Endo-Training block with an artificial root canal, by using ultrasonic techniques (US). Twenty Endo-Training block with an artificial single canal with working length 16 mm and twenty nickel-titanium (NiTi) Protaper Universal rotary files were used. 10 Shaping S1 files and 10 Shaping S2 files, were sectioned transversally within the conduit, to 5mm of the apical tip. Twenty samples were divided into four groups: Group1 and 3 received the action of DE and US, and groups 2 and 4 received the action of US. To remove the fragments we used Staging Platform and Dental Microscope. Outcome was analyzed statistically by Student t test. Statistical Analysis showed a significant difference in retrieval time of the fragments and weight loss mass of Endo training block ultrasonic tips were used, between groups that applied Ultrasonic with electrochemical dissolution and the group using only ultrasonic. It can be concluded that there was weight loss mass of separated fragment by electrochemical action, however, it was not sufficient and its use alone was inconclusive to retrieve the fragments. The procedure needs to be complemented with the use of the staging platform, ultrasonic tips and Dental Microscope.

Keywords : retrieval of fractured files; electrochemical dissolution; Nickel-Titanium; staging platform; ultrasonic tips; dental microscope.
