Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to assess in vivo the efficacy of Er,Cr:YSGG/diode laser and Diode/EDTA on bacterial count in root canal treatment in an evidence-based clinical trial. The null hypothesis being tested is that there is no difference in total bacterial count reduction between conventional irrigation and the two types of lasers used.

Thirty 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 Microbiological analysis will be done for both aerobic and anaerobic bacteria using Colony forming units. All data will be collected, tabulated, summarized, and statistically analyzed.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The use of lasers in disinfection of the root canal has been recently implemented. Lasers have bactericidal effect, and have deep penetration depth inside the root canal up to 1000 um. Thus, it can be used effectively for disinfection of the root canal system following biomechanical instrumentation reaching areas which were considered before non-reachable.

The aim of this study is to assess in vivo the efficacy of Er,Cr:YSGG/diode laser and Diode/EDTA on root canal treatment in an evidence-based clinical trial. The null hypothesis being tested is that there is no difference in total bacterial count reduction between conventional irrigation and the two types of lasers used.

Thirty 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 After disinfection, local anesthetic and tooth isolation and access cavity preparation, the first microbial samples (S1) will be collected using 3 sterile paper points and immediately placed inside sterile tubes containing transport medium of thioglycolate, cleaning and shaping with final disinfection protocol will be performed according to the group in which the participant was allocated to. Followed by S2 sample. obturation using warm vertical compaction technique. Microbiological analysis will be done for both aerobic and anaerobic bacteria using Colony forming units. All data will be collected, tabulated, summarized, and statistically analyzed.
