The aim of this study is to evaluate in vivo the post operative pain after laser root canal treatment in necrotic teeth in an evidence-based clinical trial. The null hypothesis being tested is that there is no difference in post operative pain between conventional irrigation and the two types of lasers used. Forty-five patients are equally divided into 3 separate groups : * Group A (Conventional): 2.5% NaOCL and 17% EDTA. * Group B(Dual): saline along with Er,Cr:YSGG laser and diode laser combination * Group C(Combined): saline along with 17% EDTA and diode laser combination Each patient is given pain scale chart Numeric Rating Scale (NRS) to record his/her pain level before any endodontic treatment. All data will be collected, tabulated, summarized, and statistically analyzed.
