Introduction: Enterococcus faecalis is a common bacterial species in resistant and recurrent infections. It has an active proton pump which prevents its easy inhibition leading to endodontic treatment failure. LASER and photodynamic therapy have been employed lately in improving antimicrobial chemotherapy of localized infections. Aim: To compare disinfection efficacy of 940nm Diode LASER & Photodynamic therapy(PDT) to Conventional method using 3% Sodium hypochlorite in canals of endodontically treated primary teeth. Method: Single sitting Pulpectomy was performed on 60 mandibular first primary molars, divided into 3 groups, disinfected using mentioned modalities. Disinfection potential was compared collecting samples at 3 stages using paper points, cultured and incubated for 24hrs to check change in Colony Forming Units of the bacteria. Results: Data analysis with SPSS version 20 software using Kruskal-Wallis and Mann Whitney-U test. Conclusion: The three groups showed effective disinfection as revealed by the reduction in the colony forming units of the bacteria at baseline and after intervention. However, diode laser when used in conjunction with sodium hypochlorite as a disinfecting modality was found to be the most effective for the eradication of Enterococcus faecalis from infected root canals.

Objective: To assess the efficacy of agitation of chlorohexidine (CHX) and Silver nanoparticles “AgNps” with 810nm diode laser or sonic endoactivator compared to side –vented needle on infected root canals with Enterococcus “E” 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 “CLSM” 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 < 0.05). However, Laser was significantly the highest and Endoactivator the least (P < = 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.

Objective. In endodontics, Nd:YAG laser (1064 nm) and diode laser (810 nm and 980 nm) devices are used to remove bacteria in infected teeth. A literature review was elaborated to compare and evaluate the advantages and disadvantages of using these lasers.Methods. Using combined search terms, eligible articles were retrieved from PubMed and printed journals. The initial search yielded 40 titles and 27 articles were assigned to full-text analysis. The studies were classified based upon laser source, laser energy level, duration/similarity of application, and initial and final bacterial count at a minimum of 20 prepared root canals. Part of the analysis was only reduced microorganisms and mechanically treated root canals upon preparation size ofISO 30. All studies were compared to evaluate the most favorable laser device for best results in endodontic therapy.Results. A total of 22 eligible studies were found regarding Nd:YAG laser 1064 nm. Four studies fulfilled all demanded criteria. Seven studies referring to the diode laser 980 nm were examined, although only one fulfilled all criteria. Eleven studies were found regarding the diode laser 810 nm, although only one study fulfilled all necessary criteria.Conclusions. Laser therapy is effective in endodontics, although a comparison of efficiency between the laser devices is not possible at present due to different study designs, materials, and equipment.
