NCT03668899

Brief Summary

proper disinfection of root canal system before obturation is a must for long term success of endodontic treatment, therefore a proper irrigant is mandatory, therefore investigators are studying the antibacterial effects of 4 different irrgating solutions in root canal treatment of patients diagnosed with necrotic pulps in their mandibular posterior teeth. patients will be recruited from outpatient clinic of the endodontic department in cairo university. endodontic treatment will be carried out as usual and samples from the infected root canals will be collected before and after preparation to be cultivated and analyzed at the laboratories of microbiology of faculty of medicine, cairo university
