Brief summary
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.
Detailed description
Postoperative pain is a common complication following conventional endodontic treatment. According to a systematic review, the frequency of endodontic postoperative pain is between 3% and 58% of patients.Postoperative pain is attributed to chemical, mechanical and microbiological factors. Residual microorganisms remaining due to the complexity of the root canal system and the limited penetration capability of conventional irrigants are directly responsible for Post operative pain 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 will be given pain scale chart (NRS scale) to record his/her pain level before any endodontic treatment. After disinfection, local anesthetic, tooth isolation, access cavity preparation and final obturation. Patients are asked to mark on a numeric rating scale (NRS) to determine incidence of postoperative pain and rate its intensity at 6, 12, 24, 48, 72 hours, and 7 days after the procedure All data will be collected, tabulated, summarized, and statistically analyzed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative pain assessment | Measure changes in post-operative pain 6 hours after intervention in the three groups using NRS | Patients will be asked to mark Numeric rating scale (NRS) to determine incidence of postoperative pain and rate its intensity. The NRS consisted of a line anchored by two extremes "No pain" and "the worst pain". * Pain level assigned to one of 4 categorical scores: * No pain (0), Mild (1-3), Moderate (4-6) and Severe (7-10). |
