Abstract

Aim: Comparative evaluation of isthmus cleaning ability of photodynamic therapy versus sonically and ultrasonically activated sodium hypochlorite: an in vivo study. Materials and Methods: A total of eighty-eight non vital teeth were selected. After biomechanical preparation teeth were randomly divided into 4 groups for final irrigation and disinfection. Group1 - Control group (n=22): No irrigant activation. Group 2 - Sonic irrigation group (n=22). Group 3- Passive ultrasonic irrigation group (n=22). Group 4- Photoactivated disinfection group. The sterile cotton pellet was placed in the pulp chamber and the pulp chamber was sealed with temporary cement followed by immediate extraction. Teeth were stored in formalin and sent for histological preparation. Sectioning off each group’s slides was performed and stained. Blinded and mounted sections of all the groups were evaluated using a stereomicroscope at 40X/100X/400X magnification.  Result: Mean cleanliness values of the isthmus at different levels (1,3 and 5mm) levels evaluated and comparison of isthmus cleanliness were evaluated. There were significant differences between cleanliness in all groups at different levels. The highest cleanliness was found in group 3 (ultrasonic) (p < .000). Conclusion: From the results of this dissertation, it was concluded that the proultra tips gave the better result.
