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.

The number of appointments necessary to treat infected root canals is one of the most controversial issues in endodontics. This study evaluated, in dogs, the response of the periradicular tissues to the endodontic treatment of infected root canals performed in a single visit or in two visits, using different interappointment dressings. Periradicular lesions were induced by inoculating Enterococcus faecalis in the root canals. After confirming that a periradicular lesion developed, the root canals were treated within one or two visits, using either ozonized oil or calcium hydroxide in camphorated paramonochlorophenol (CMCP) as an intracanal medication. After 6 months, the animals were sacrificed and the specimens were processed for histological and histobacteriological analysis. The root canals treated in a single visit showed a success rate of 46%. When a calcium hydroxide/CMCP-based interappointment intracanal medication was used, 74% of the cases were categorized as success. In cases where ozonized oil was used as the intracanal medication, a success rate of 77% was observed. These results of the present study demonstrated that the two-visit treatment offered a higher success rate compared to one-visit therapy. In addition, ozonized oil may potentially be used as an intracanal medication.
