	abstract = {<p>Objective: To assess the efficacy of agitation of chlorohexidine (CHX) and Silver nanoparticles {\textquotedblleft}AgNps{\textquotedblright} with 810nm diode laser or sonic endoactivator compared to side {\textendash}vented needle on infected root canals with Enterococcus {\textquotedblleft}E{\textquotedblright} Faecalis biofilms. Material and Methods: Sixty-five extracted human premolars with single oval canals were instrumented by protaper system up to F3. Biofilms of E. faecalis were generated based on a previously established protocol. Two teeth were used to check the biofilm formation, then the remaining Teeth were randomly divided into three equal experimental groups according to agitation techniques used: group 1 (810 nm diode laser with 1 watt), group 2 (sonic endoactivator) and group 3 (Side vented needle). Each group was further divided into three equal subgroups according to the irrigant solution into; subgroup A: chlorohexidine, subgroup B: silver nanoparticles and subgroup C: distilled water: Confocal laser scanning microscopy {\textquotedblleft}CLSM{\textquotedblright} was used to assess bacterial viability. Data were analyzed by appropriate statistical analyses with P = 0.05. Results: Regarding the activation method, all groups had a significantly high percentage of dead bacteria (P \&lt; 0.05). However, Laser was significantly the highest and Endoactivator the least (P \&lt; = 0.001). Diode laser agitation of AgNps irrigant showed the highest reduction percentage of bacteria (78.1\%) with a significant difference with both CHX and water irrigation, Conclusion: Under the condition of the present study; results reinforced that laser activation is a useful adjunct, 810 nm diode laser agitation of AgNps or chlorhexidine was more effective in disinfection of oval root canals than endoactivator and side vented needle techniques.KeywordsDentinal infection; Silver-nanoparticles; chlorohexidine; agitation; Diode Laser; Sonic endoactivator.</p>
