Abstract

Aim :To determine the effect of the combined use of solvents (eucalyptus oil and orange oil), file retreatment, ultrasonic irrigation and rotary brushes on the cleanliness of the apical thrirdroot canal that were re-treated.
Materials and Methods :25 dental samples which were divided into 5 treatment groups.  Each group consists of five sample groups.  Group A were specimens whose root canal filling material was removed using eucalyptus oil, file rotary retreatment and ultrasonic irrigation techniques.  Group B were specimens whose root canal filling material was removed using eucalyptus oil, file rotary retreatment and rotary brushes irrigation techniques.  Group C were specimens whose root canal filling material was removed using orange oil, file rotary retreatment and ultrasonic irrigation techniques.  Group D were specimens whose root canal filling material was removed using eucalyptus oil, file rotary retreatment and rotary brushes technique.  The control group was specimens whose root canal filling material was removed using only a rotary retreatment file.
Results : Statistical assessment in all groups had effect and a significant difference in root canal re-treatment using solvents (eucalyptus and orange oil) and irrigation techniques (PUI and rotary brushes) was third apical root canal cleaning (p < 0.05).
Conclusion :This study showed that was an effect of using solvents (eucalyptus and orange oil) with irrigation techniques (PUI and rotary brushes) on the cleanliness of apical third of root canal. Also there was no significant difference between used eucalyptus oil with orange oil and PUI irrigation with rotary brushes on the cleanliness of the apical third root canal. However, the use of solvents and irrigation techniques can help clean the filling material in the apical third root canal in endodontic retreatment.
