Effect and Comparison of two Different Irrigation Protocols and two Irrigating Needles on Post Operative Pain and Oral Health Related Qualityof Life (OHQOL) after Endodontic Treatment – A Randomised Clinical Trial.

During endodontic treatment, Conventional irrigation with NaOCl& EDTA, forms precipitate and decreases surface hardness of root dentin hindering NaOCl action. To overcome the above disadvantage , combination of NaOCl& HEBP(1-Hydroxyethylidene-1, 1-Bisphosphonate) used which does not alters the NaOCl action and surface hardness of root dentin.

In conventional needle irrigation, the chances of apical extrusion of debris and irrigants are more which is the most important factor in  causing post operative pain. Hence to overcome the Post operative pain, newer advances like double side vented needles were introduced. Hence, a combination of new irrigation protocol using NaOCl + HEBP(1-Hydroxyethylidene-1, 1-Bisphosphonate) and double side vented irrigation needle tips might be helpful in reducing the post operative pain and improves the oral health quality of life.
